Maryland, Virginia winters turn less snowy as New York, Boston enjoy snow bonanza

The northern end of the Northeast megalopolis lies in the proverbial sweet spot for snow, as general observations have shown over the years. A closer examination of the historical record reveals not only increases in the seasonal snowfall totals for Boston and New York City, but also unearths this all too predictable truth: Maryland and Virginia winters are becoming less snowy.

Could it snow in Tampa, Florida this weekend?

The jet stream promises to take a huge dip this weekend, with cold air plunging deep into the Sunshine State of Florida. Since last weekend, the GFS weather model has hinted a little light precipitation might team up with the incoming stream of arctic air. There’s a very small chance this combination could squeeze out a few rare snowflakes along Florida’s central west coast Sunday morning.

Asheville, N.C.: Suffering worse snow drought than Washington, D.C.

Here’s some news that may shock snow-starved Washingtonians: we don’t have it all that bad. For all the attention that’s been given to D.C.’s longest drought without a 2 inch or greater snow event, and rightfully so, one city in the South, Asheville, N.C., is actually suffering through a longer period of even paltrier snow amounts.

New England blizzard: Two feet of snow possible from East Coast bomb, Boston may be ground-zero

Confidence continues to grow that Boston will face a major to historic blizzard Friday into Saturday. New York City may also experience a period of blizzard conditions, but questions remain about how much precipitation falls as snow. Washington, D.C. will likely just get grazed by rain and, perhaps, a little wet snow at the onset.

Colorado wildfires: is lack of spring snow the smoking gun behind the blazes?

When we discussed the role of weather yesterday in Colorado’s wildfires, we mentioned the historic, sweltering temperatures, the state-wide drought, low humidity, and gusty winds. But we neglected perhaps the key environmental contributor: the profound lack of spring snowpack across the state.

More than 7,700 daily record high temperatures were set (or tied, compared to just 287 record lows), in some cases by mind blowing margins and over multiple days. It’s no surprise that, after data were crunched, scores of cities easily set March monthly records for warmth.

The warmth is so intense in some areas, high temperatures have reached mid-summer levels while it’s still winter. The longevity of the heat is as impressive as its intensity: temperatures have run some 20 to 45 degrees above normal for 6 to 10 straight days in some areas.

The dearth of snow this past winter was a bummer for skiers and winter weather lovers. But thanks to the paltry snow output, residents along the Mississippi and Missouri rivers can probably breathe easier this spring. NOAA announced today the risk of spring flooding is the lowest in four years.

Historic record warm weather brings summer to central and eastern U.S.

Temperatures more characteristic of June have broken hundreds of temperature records over the last several days and promise to continue into the next week in many areas. In some places, temperatures have been an eye-popping 30-40 degrees above normal, nearing or surpassing the warmest temperatures ever recorded so early in the season.

Widespread record warmth to continue next 7-10 days; Midwest severe weather possible next week

Large parts of the United States are right now experiencing one of the most spectacular warm spells in modern times. On Sunday, 188 record highs were tied or broken in the U.S. and 117 on Monday. Similar numbers will likely come in today as well. And record warmth is likely to keep coming for the next 7-10 days.

December through February, meteorological winter: 4th warmest on record in U.S.

Throughout the Lower 48 states, there was no escaping milder than average weather this past meteorological winter (December through February). Overall, it was the 4th warmest in the last 117 years.

After experiencing one of the mildest winters in modern times, the Lower 48 is staring down …you guessed it … a warm start to Spring. Earlier long-range forecasts for above average temperatures in March are now supported by multi-week predictions from the global weather models. Fortunately, as outlined by the Storm Prediction Center (SPC), severe weather prospects appear limited through the next week at least.

Tornado outbreak: recap of deadly March 2 storms in Tennessee and Ohio Valley, South

The tornado outbreak, which ravaged the Tennessee Valley, the Ohio Valley, and parts of the South last Friday, will go down in the record books as one of the worst, if not the worst, March tornado events on record. NOAA has confirmed 45 tornadoes touched town, and continues to conduct storm surveys. A lot has been written about Friday’s outbreak. Here’s a guide to some of the most significant information.

Toughest places to forecast weather: a match for Washington D.C.?

From trying to nail down the rain-snow line in winter to predicting the timing and location of pop-up thunderstorms in summer, the fickle nature of D.C.’s weather presents problems for even the most seasoned forecasters. What forecast challenges do other regions contend with? Are they as difficult as Washington, D.C.’s?

Severe weather to strike central U.S. and Tennessee Valley, a precursor to active March?

A powerful storm system will move across the middle of the country today and introduce a chance for severe weather, including tornadoes, over a large area from the southern Plains to the Tennessee Valley. Given the impressive tornado numbers so far this year, and the fact that La Nina is expected to be in place until mid-spring at least, it might be tempting to think we’re lining up for another big year. Not so fast.

Is winter over for most of the U.S.?

For places like D.C., Philly, New York, and obviously points farther south, winter may well be about over (not that it really got started). With a mainly mild and wet close to February, and longer-range models predicting mostly warmer-than-average weather during March, I don’t think odds of adding to the meager snow totals along I-95 corridor are good. That’s not to say winter is over for everyone in the country. Far from it. There are some places that are staring down some nasty cold before the turn of the month.

According to the weather model consensus, a westerly flow of mild air has begun to flood western Canada in a way that will soon allow a broad cyclonic (counterclockwise) flow to develop west of the Continental Divide. This will provide relief from the recent frigid temperatures in the Plains, and more likely than not, set the stage for …and winter lovers will hate this… a mild and wet finish to February.

Unseasonably cold air to blast eastern U.S. this weekend

After a few mild, spring-like days this week in the East, a cold shot from Canada will move in for the weekend and deliver a brief dose of February for a change. It does seem a little odd that an upcoming 2-3 day bout with chilly air – carrying temperatures perhaps as much as 8-16°F below average- deserves headlines. But given that winter 2011-12 has so far given us a temperature map like this, a cold snap of any kind is worth discussing.

But, as we have seen so often this season, the chill didn’t last. In fact, as we move into early February, the weather pattern across the nation as a whole will instead be marked by bouts of mild conditions, rain and thunderstorms more reminiscent of early spring.

If you’ve followed the struggle by the U.S. Coast Guard Cutter Healy and the Russian tanker Renda to re-supply Nome, Alaska with badly needed fuel oil, you know that a crisis appears to have been averted. Ironically, exactly 87 years ago—in 1925--during a similar Alaskan January*, another crisis in Nome was narrowly averted—this one of a medical nature. It was called the “Great Race of Mercy,” the hastily arranged rescue operation to save Nome from a potential diphtheria epidemic.

Before then, however, exceptionally mild air will once again surge from the Plains to the East Coast late this week and bring a very warm start to the Thanksgiving weekend for many locations east of the Rockies.

Latest Texas drought outlook: grim with a few drops of hope

Among the long list of billion dollar weather-related disasters during 2011, there is one event that is still ongoing, with no end in sight, its economic ramifications growing with each passing day. The Texas drought - already the Lone Star State’s worst one-year drought on record - is now expected to last through at least next summer, and perhaps far longer than that, according to the latest climate projections released by NOAA’s Climate Prediction Center and recent testimony by the Texas state climatologist.

Record smashing cold in interior Alaska, Fairbanks

A frigid Arctic air mass, unusual even by Alaska standards, is dropping the mercury in the state’s interior to unheard of levels in mid-November. Stunningly low temperatures in the -35 to -50 range have gripped the region since Tuesday. These temperatures are some 25 to 40 degrees colder than average.

Multiple tornadoes, violent storms tear across Southeast, killing 6

As many as 16 tornadoes ripped through the Southeast Wednesday, killing at least six people and injuring dozens. Tornadoes touched down in Alabama, Georgia, South Carolina and North Carolina, states that have seen more than their share of tornado devastation in 2011.

Thanksgiving travel weather: Pacific Northwest and Southeast may be trouble spots

The Bureau of Transportation Statistics reports during the five days around Thanksgiving, typically about 10.8 million trips are taken each day, nearly double the daily average. For air, rail, and road travel, inclement weather can create major headaches.

Arctic air building in Alaska and Canada, will it stay there?

A core of exceptionally cold air has recently settled into parts of Northwestern Canada and Alaska. There are times when a temperature map like this one sends shivers down the spines of weather forecasters in the Lower 48. This is because in theory, it doesn’t require an unusual set of circumstances to drive that polar air into the United States. But this time around, the global weather pattern is in a shape that will likely keep most of that arctic air up there for a while.

Wild rides: the 11/11/11 Great Blue Norther and the largest wave ever surfed

Look out when giant waves come crashing down. That’s what happened in Chicago 100 years ago when the temperature dropped from a record high of 74 to a frigid 16 in the same day (November 11, 1911). Even more stunning, Springfield nose-dived from 80 to 8 degrees, a precipitous 72 degree drop.

Oklahoma weather stations record tornado measurements before destruction

On Monday, several large, dangerous tornadoes ripped through southwest Oklahoma. Two of Oklahoma’s 120 automated weather stations in its “Mesonet” stood in the way and were taken out. But they recorded valuable data in the process demonstrating jaw-dropping pressure drops and wind accelerations.

Alaska storm brings epic wind, waves, coastal flooding and snow

A storm of historic intensity continues to pound the west coast of Alaska today. Twice the size of Texas, the storm is as deep as a category 3 hurricane. The National Weather Service is calling it a “life-threatening epic storm” due to its dangerous combination of towering waves (observed at 40 feet in the Bering Sea), hurricane-force winds, storm surge flooding, and blinding snow.

The face of La Nina emerging

During the past few days, a new weather pattern has emerged that will likely stick around for the next one to two weeks at least. It will feature a strikingly different temperature and rainfall distribution than experienced during much of October.

Alaska storm to produce “historic” hurricane-like conditions

A ferocious, dangerous storm in the north Pacific is on a collision course with the west coast of Alaska. Referred to as the “Bering Sea Superstorm” by the National Weather Service Office in Fairbanks (NWS), damaging winds, severe beach erosion and major coastal flooding are expected. In some locations, heavy snow and blizzard conditions are also forecast.

Oklahoma earthquake: just one of state’s several record-setting natural events in 2011

In the heart of tornado alley, Oklahoma is no stranger to mother nature’s wrath. But in 2011, extreme environmental conditions have risen to another level, with records set for a potpourri of natural hazards including earthquakes, heat, cold, wind, hail, and snow!

Denver double whammy: second 6” snowstorm in week

Deja Vu for Denver. After six inches of heavy, wet snow weighed down the mile high city last Tuesday night and Wednesday, six inches of more powdery flakes stacked up exactly one week later.

Global warming and extreme weather: Northeast heavy precipitation spiking in winter

Was the weekend’s “epic” storm in the Northeast part of a long-term trend? It’s certainly not inconsistent with the region’s experience in recent years. Data from the National Climatic Data Center indicate heavy cold season (October to March) precipitation events are intensifying.

Historic October Northeast storm: Epic. Incredible. Downright ridiculous.

Epic. Incredible. Downright ridiculous. These words best describe the historic snowstorm that delivered a crippling wallop to parts of the mid-Atlantic and Northeast over the weekend. Widely referred to by its social media moniker, “Snowtober,” the storm smashed records that had stood since the beginning of the reliable instrument record in the late 1800s (and in some cases, even longer than that), and upended assumptions about what a fall nor’easter can do. The heavy, wet snow pasted onto trees still bearing foliage in many areas, weighed down power lines and caused more than three million power outages.

Nor’easter poses big snow, power outage risk to interior mid-Atlantic and Northeast

A powerful fall storm, more characteristic of winter, promises to bring a large swath of heavy snow for interior sections of the mid-Atlantic, and locations just west of I-95 in New England. According to NOAA, 25 million people are under winter storm watches.
