Alabama tornado outbreak visuals: jaw-dropping radar and satellite imagery

This post contains some of the most extraordinary imagery from Wednesday’s deadly and historic tornado outbreak in the South. The latest reports indicate fatalies from the outbreak now exceed 342 people, surpassing the number of deaths from the 1974, and the most people killed by tornadoes in a two-period since April 5-6, 1936 (when 454 people died).

Forecast: A superior Saturday Spring day

By and large, our Saturday’s this spring have been less than stellar. But aside from a high tree pollen count (which I can mitigate with a Zyrtec), there’s nothing I can find fault with today. Sunday doesn’t like bad either, but increasing clouds and a slight afternoon shower chance mean it won’t stack up to today. Enjoy this overall nice weekend, because the early to middle portion of next week look foul.

PM Update: Clearing out for an outstanding start to weekend

Lots of folks complained about the abrupt shift from winter to summer with no spring in between. But this weekend, we get spring weather at its finest. Today wasn’t too shabby either, with a fair dose of sunshine through early afternoon. And even though it’s clouded over late, we’ve still managed to reach around 70. We’ll shed these clouds soon, and you’ll love the outlook for Saturday...

Greg Carbin: On call at NOAA’s storm center

Greg Carbin is the warning coordination meteorologist at the National Oceanic and Atmosphere Administration’s Storm Prediction Center (SPC) in Norman, Okla., which has 43 employees, including more than 20 meteorologists. This federal center issues forecasts and watches for severe thu nderstorms and tornadoes across the entire United States. I talked with Carbin about his experience during Wednesday’s devastating tornado outbreak in the South.

PM Update: Welcome clearing skies

After a tumultuous nearly full day of monitoring the atmosphere for tornadoes, much neededtranquility has moved into the metro region. Skies have partially cleared with emergent afternoon sunshine. Well southeast of town toward St. Mary’s and Calvert county, a thunderstorm remains possible through sunset, but elsewhere, the clearing trend should continue.

Tornado outbreak for the record books: how did deadly, destructive event happen and what does it mean?

The devastating tornadoes that chewed up swaths of the South and Southeast yesterday were rare, mile-wide plus beasts, causing hideous damage, including denuded trees, flattened buildings, and pancaked cars. Thanks to the 139 tornadoes reported Wednesday (this number will change as the National Weather Service conducts their damage assessments), April 2011 has now almost certainly seen more tornadoes than any other April on record since 1954, beating out 1954, when an estimated 407 tornadoes descended from the heavens.

Tornado watch east and southeast of D.C. through 3 p.m.

Since just after 2 p.m. yesterday, the metro region has been under a tornado watch. By the time it expires at 3 p.m. (unless it’s canceled early), the watch will have run for more than a full day, longer than I have ever witnessed in this region. A Flash Flood Watch also covers the region through 3 p.m. Thunderstorms, some rotating, will continue moving from southwest to northeast through the metro region. Much of the activity has tracked through the far western suburbs this morning - from Fauquier county into Loudoun, eastern Frederick and western Montgomery county up into Carroll county. As the morning wears on, storms developing to the southwest should target the immediate metro region and then the eastern suburbs by midday into the early afternoon. Torrential rain, damaging winds and tornadoes are possible in storms moving through.

Yes, we finally lose the humidity, and get some nice days to enjoy all the May flowers that our earlier April showers have helped along. Yes indeed, May Day arrives on Sunday and it will be a fine one to dance around your May pole. Next storm potential is not expected until Monday night.

Washington D.C. area’s worst five tornado events

The tornado season in 2011, off to a fast and furious start, is likely to become one for the record books. Thus far, the Washington, D.C. metro region has largely been spared, with only very weak tornadoes in the region. While the Washington area does not get the quantity or usually the severity of tornadoes that impact the states to our west, we have experienced a number of dangerous twisters over the past century. This post contains a list of what I consider to be the Washington, D.C. area’s top five most damaging and deadly tornadoes...

Dangerous severe weather outbreak threatens for second straight day

Yesterday, more than 400 severe weather reports were logged by the National Weather Service, including 38 tornado reports. The worst tornado, estimated to be one half mile wide, occurred in Vilonia, Arkansas where there was major structural damage and at least four lives were lost. In many of the same areas where severe weather occurred yesterday, there is a moderate to high risk of severe thunderstorms today. In addition to severe thunderstorms, significant flooding has occurred and is ongoing.

Royal Wedding weather forecast: Turning cooler with shower risk for London Friday

It was too good to be true. Anyone who knows anything about London weather knew the recent stretch of sunny, warm weather wouldn’t last forever. As Prince William and Kate Middleton’s big Royal Wedding day approaches, some of the warmest late April weather in more than 100 years is fading away. In its place, more typical London weather settles in.

Forecast: Muggy 80s with slight storm chance

Yes, the humidity is ticking up and yes, thunderstorms will gradually be making their presence more known again. But can you argue that sun and 80s are really bad things for late April? When the showers/storms become more frequent late tomorrow into especially Thursday, I’ll tend to agree that we are in a deteriorating weather situation. By late tomorrow, we’ll also be back in the slight risk area for severe weather. The big cold front passes Thursday with more storms, but better weather (less humid, comfortable 70s, returning sunshine) arrives just in time for the weekend.

Cities, small towns, rural hamlets - even international airports - have suffered severe damage. The atmosphere has been behaving like an unruly teenager, with 275 tornadoes recorded so far this month. What, if anything, might La Nina and global warming have to do with this?

Rain continues tonight, but after a warm front pushes to our north, we should enjoy a dry interval for part of Saturday morning and afternoon. However, rain may return later in the day.

Powerful storm plows east, weakens some

Another big round of severe weather smacked the east central U.S. yesterday, resulting in just shy of 900 storm reports for high winds (493), large hail (349) and tornadoes (34). The responsible storm system, which also dropped 2-10 inches of snow in portions of Minnesota, Wisconsin ( a record 9.9 inches in Green Bay) and northern Michigan, lifts northeastward today, dragging a cold front through the East. Some severe thunderstorms are possible along the front, but they should be far less numerous than yesterday.

The width of a lightning bolt, part II

Last year, I wrote a post about determining the width of a lightning bolt by using a tree that was struck by lightning as a measuring post. By measuring the burn mark on the wood I was able to determine that the diameter of lightning is roughly the size of a pencil to about an inch. This winter, I found another tree that was struck by lightning. This tree’s measurements were consistent with what I had determined from the tree in my first post. However, whereas I found only the bark exploded on the first tree, both the wood and bark exploded on the second tree along the path of the electric current.

The weather this spring just cannot seem to hit a stride, and that trend is set to continue. We’ve got forecast highs ranging from the 80s to the 50s (maybe even the 40s) over the next several days, with some days dry and some days showery and/or stormy. Today is one of those potentially stormy days, and if storms do develop they could be severe.

Images of day: Surreal Texas wildfire photos from McDonald Observatory

In far west Texas lies McDonald Observatory, a major astronomical research center of the University of Texas at Austin. In recent days, large wildfires have burned in its vicinity, sparked by an extreme drought and fanned by gusty winds. On Monday, April 11, the wildfires briefly knocked out power to the Observatory. Though it has been closed to the public at times over the last week, the Observatory has not been harmed and plans to re-open Wednesday. The images in this post show some of the breathtaking imagery of the surrounding fires...

PM Update: A shot of heat tomorrow, but risk of strong storms

Depending on where you live, it’s been either rainy (frequent showers/storms) and cool, or cloudy and warm (with isolated, brief shower activity). The dividing line has been a warm front in the vicinity of central Maryland. To the north, temps have held in the 50s to low 60s, and to the south, it’s been in the mid-60s to near 70. As the warm front lifts north, everyone gets a taste of warmth tomorrow, before a cold front brings another round of showers and thunderstorms late in the day, which could be strong.

Forecast: Warmer, more clouds, some showers

The past several weeks have all offered one warm day in the 80s. For the past two weeks, that day was Monday, but this week’s winner is Wednesday. We’ll progress in that direction today with highs well into the 70s under mixed skies. But the warm air (and humidity) keep pumping into the area tomorrow too, allowing most locations to reach the 80s. Spring-time variability is the constant as Thursday goes cooler-than-normal (but nice) and Friday goes much cooler with maybe some wet weather (not-so-nice).

Tornadoes reported in Frederick, Carroll counties Saturday and near Leesburg

Tornadoes touched down in several places in Frederick and Carroll counties during Saturday’s severe weather outbreak in the region according to preliminary reports from the National Weather Service (NWS). Unlike the storms in the Carolinas and southeast Virginia, these storms were relatively weak, and caused only minor damage and no injuries.

Clouds didn’t keep temperatures from nearing 70 today, and we’ll surpass that mark tomorrow with little trouble. With flooding concerns still ongoing, just a few showers or storms threaten late Tuesday.

Massive three-day tornado outbreak kills dozens; storm video and imagery

One of the largest three-day tornado outbreaks in history swept across the country Thursday through Saturday, with 241 tornado reports in 14 states, and killing at least 45 people. Although the official tally of confirmed tornadoes is still being counted as meteorologists complete storm damage surveys, it’s already obvious that this was no ordinary early-spring severe weather event.

Forecast: Trending warmer, but episodic storm chances

As inconsistent as the weather has been this spring, it is trending warmer. Whereas over the last couple of weeks we saw several days with highs stuck in the 50s, none of that this week. But we do continue the maddening pattern of showers/storms every two or three days, including once again this Saturday. We will fit in the occasional pleasant day in between, starting with today.

Image of day: Explosive tornado producing Oklahoma storms from space, Texas fire

Over the course of just a few hours Thursday afternoon and evening, a seemingly harmless band of clouds stretching across central Oklahoma exploded into violent, rotating thunderstorms that produced multiple tornadoes. In the later frames of the video in this post, notice how clouds appear to bubble up. That’s evidence of overshooting tops - dome-like protrusions in the thunderstorm’s anvil, often indicative of severe storms. This animation also nicely illustrates the swirl and intensification of low pressure over western Kansas. Finally, if you look closely, you can see smoke extending from a fire in north central Texas, currently suffering from severe drought.

My words one week ago hold true again today: “Here’s to one of the rarities, a perfectly spring day.” See now, don’t you wish I was doing the forecast every day? It does appear that our timing is not doing so well right now as it is going to be a soggy Saturday, like around an inch wet. The showers put a chill back in the air and, unlike last week, there is no big warm up showing up to start the new work week.

NOAA Climate Service squashed in FY 2011

For an number of years, NOAA has been working toward the development of a Climate Service. The premise of the Climate Service is that it would make climate information and data available in “accessible and timely” formats to assist people in making decisions. But in their Continuing Resolution for Fiscal Year 2011, Congress and the White House have blocked any funding for the effort.

Putting this winter in context: how severe was it?

For all the talk of this past winter being one for the record books, the reality is much different. While extremely cold conditions gripped some sections of the country at various times during the past few months, the winter of 2010-2011 actually served up temperatures that were just a little cooler than average over the entire contiguous United States. Records from thousands of weather stations across the lower 48 states from December through February show the past season did not even crack the coldest one-third of winters since 1895, when very reliable recordkeeping began. So why was there so much talk about it being so cold?

We’re able to string together a pair of nice days tomorrow and Friday, before rain chances arrive again Friday night or Saturday morning. As a whole, the weekend doesn’t look great, though Sunday could be decent.

Congress turns a blind eye to climate science

Last week was a bewildering one for those who recognize the abundance of compelling scientific evidence showing that the climate system is changing, and that this is very likely due in part to human activities. While the news cycle was dominated by the down-to-the-wire budget negotiations in Washington, ongoing unrest in the Middle East, the nuclear crisis in Japan, a major congressional debate on climate change regulations took place in both the House and Senate that vividly demonstrated how far off the rails we’ve gone in public discourse of climate science and policy.

April 1861: The War Between the States begins— what was the weather like?

On April 12, 1861, Abraham Lincoln, 16th president of the United States, had been in office only 39 days when, at 4:30 A.M., Confederate cannons opened fire against Ft. Sumter, SC, a small Union garrison in Charleston harbor. The Civil War had begun. Most historians agree that the weather was a huge issue during the entire conflict but strangely, at the time of the Ft. Sumter bombardment, little was reported about the weather.

How accurate are April hurricane season outlooks?

When we published a blog post summarizing Colorado State’s 2011 Atlantic hurricane season outlook Wednesday, I was stunned by the skepticism expressed by readers about the credibility of such outlooks. So I thought it would make sense to take a look at how skillful at how well/poorly CSU’s April outlooks have performed over the years. I found that although they haven’t demonstrated significant skill from a purely statistical standpoint, most years they’ve been on the right track.

Washington D.C. March 2011 in review: slightly cold temps and wet

Our recently-ended March 2011 was a strange month with lots of temperature variability and some interesting precipitation events. From a temperature standpoint, the month was 5.6 degrees colder than last March and almost 1degree colder than the thirty-year fixed normal (1971-2000). Our warmest day was that excellent 80-degree high temperature on March 18 and our coolest day was the 41-degree high on March 3 followed by the 42F just last week on March 31.

UnitedCast: Cool 50s at the Plex

It’s a few degrees cooler than if this game were in the city at RFK. But overall we’ve got a decent evening for soccer with any shower likely to be a quickly passing one.

PM Update: Cold now, but temps rebound Wednesday

What a volatile past 24 hours. We’ve gone from record warmth in the mid-80s to early morning severe thunderstorms to wind-chilled 40s this afternoon. Although a blustery evening lies ahead, the next 24 hours promise to be much more placid than the previous.

On Sunday evening, thunderstorms blew up over the region as a warm front lifted northward (setting the stage for Monday’s record heat). While nowhere near as intense as the storms that came through this morning, Sunday’s storms were full of electricity. PhotographerMaxwell Kruger took full advantage of the light show

Recapping this morning’s severe storms

An intense thunderstorm squall line raced through the metro region between 3:30 and 5:30 a.m. producing powerful winds and torrential rain. But as the storms passed by at a stunning 60-80 mph clip, the worst of the weather was in and out of most areas in about 10-15 minutes. Five tornado warnings, five severe thunderstorm warnings and four special marine warnings were issued by the National Service (NWS) as the storms tore through.

Forecast: Soggy morning, turning sharply colder

Apparently it is far too early in this spring to expect more than one nice day in a row around here. After this morning’s clamor, we’re back to the story of cooler weather with brisk wind chills and below normal temperatures. We’ll try to do better tomorrow as temperatures make their way back up through the 60s, and Thursday has a shot at the low 70s. But Friday into the start of the weekend becomes a little murky again.

Intense storms blow by

Showers and thunderstorms are rapidly moving through West Virgnia out ahead of a front and they promise to bring rain in the overnight.

PM Update: Record heat before rain and storms

Today’s highs near or above 80 are fleeting, and tomorrow afternoon’s readings could easily be 30 degrees lower behind the cold front. Between now and then, some rain and storms are a decent bet.

Odd squirrel behavior and the weather

The Post’s John Kelly initiated the inaugural squirrel week today. Squirrels are no strangers to the Capital Weather Gang. Readers have frequently remarked about the behavior of these nut foraging rodents leading up to winter as well storms.

Another record low for Arctic sea ice

Each month seems to bring new evidence of the transformation underway in the rapidly warming Arctic. Late last month, the National Snow and Ice Data Center (NSIDC) announced that the maximum Arctic sea ice extent for 2011, which occurred on March 7, tied for the lowest such value since satellites began making observations in 1979.

Forecast: Warm spike, then a brief cold plunge

For weeks, many have awaited a day like today with sunshine and temperatures near 80. But a strong cold front punches through the region late tonight and early Tuesday with a round of gusty storms, smacking us back down to the blustery 50s. But from Wednesday through the weekend, temps should be at or above average, sure to put a smile on the face of warm weather fans...

Forecast: Spring makes a major comeback

After a fairly nice day today (cool to start but warming steadily), a few showers may pepper the region tonight. By Monday, wow, we have a gush of warm air - and instability that could have thunderstorms crackling Monday night into Tuesday morning.

NatCast: Nicer (warmer) than Opening Day

Decent game weather with some sun at least at the start - clouds try to increase as the game goes on - and temperatures rising through the 50s to maybe near 60.

Senators call for supporting NOAA satellites

On Thursday we reported on NOAA’s warning to congressional appropriators that budget cuts to a major satellite program, known as the Joint Polar Satellite System or JPSS, would severely erode the accuracy of weather forecasts. Today, six Democratic Senators took up NOAA’s cause, sending a letter to Senate Majority Leader Harry Reid (D-Nev.) as well as Minority Leader Mitch McConnell (R-KY) and the chair and ranking member of the Senate Appropriations Committee. The senators are seeking full funding for JPSS during the remainder of the 2011 fiscal year.

PM Update: Can’t shake the clouds

Darn clouds. Today’s dearth of sunshine resulted in temperatures failing to surpass 50 for the eighth time in nine days. On the other hand, it was about five degrees warmer than yesterday. Tomorrow we take another five or so degree step towards April normalcy. However, we may have to dodge some rain showers in the process.

Civil War relic hunting in snow

This past Sunday, I joined the Diggin’ in Virginia spring relic hunt in Culpeper, Virginia. The weather was anything but springlike, however, as the first day of the hunt began with the ground covered by an inch of wet snow and light snow falling steadily from the sky. The weather did not deter over 200 relic hunters who had signed up for the event and the hunt continued without a weather delay.

Video of day: Super sandstorm blasts Kuwait

Less than a week ago, Friday, March 25, a severe sandstorm very suddenly enveloped parts of Kuwait. It caused traffic jams, stranded travelers, disrupted cell phone service, damaged crops, hospitalized hundreds due to dust inhalation, and temporarily shut down Kuwait’s international airport. The Arab Times described the storm as a “tsunami of sand” with a “menacing black” wall of dust, noting it lowered visibility to almost zero.

NOAA warns weather forecasts will suffer from budget cuts

National Oceanic and Atmospheric Administration (NOAA) is sounding the alarm on budget cuts, telling Congress that a failure to restore funding for development of the next generation of polar orbiting satellites, known as the Joint Polar Satellite System (JPSS), would significantly reduce the accuracy of weather forecasts, particularly medium-range forecasts, and may have an outsized impact on forecasts for extreme events, such as blizzards or hurricanes.
