NatCast: Beautiful baseball weather

It’s about as good as it gets for a late afternoon spring game. Temps are near 70 to start, but fall back through 60s during the late innings when a light jacket may be warranted. Clear skies.

NatCast: Not too cool or too breezy

A fine night to hit the ball park. For those of you with a low chill threshold, a jacket for game's end is not a bad idea. The earlier in the day cold front and storms should be long gone and dry weather prevails.

Tornadic storms possible again early Thursday morning

A cluster of strong to severe thunderstorms is approaching the region from the south and southwest. The storms moving in have a history of producing hail and strong winds. They are likely to impact the metro region, generally west of I-95, between 6:00 and 8 p.m from south to north. A tornado watch remains in effect through 8 p.m. Strong tornadoes are unlikely, but an isolated weak tornado could spin up.

PM Update: Foul weather Friday

Sorry for the grim headline, but there’s no escaping Friday’s miserable forecast. At least, we got in a good one today, with filtered sushine and mid-to-upper 60s this afternoon (update: we’ve touched 70 as of 4 p.m.). We cloud over tonight, with rain developing late that continues throughout tomorrow.

Big coastal storm to affect mid-Atlantic and Northeast late Thursday into Friday

All signs currently point to the development of a significant nor’easter late Thursday into Friday. However, for the cities along I-95 from D.C. to Boston, much of precipitation will fall as cold rain with limited prospects for snow on the storm’s backside.

Although the Atlantic hurricane season in 2010 tied for the third most active on record, few noticed as storms largely avoided the U.S. mainland. In its preseason outlook released this morning, AccuWeather cautioned that the risk of U.S. landfalling storms is higher during 2011 despite its prediction for fewer storms.

Forecast: Cold shower chance today; any snow?

Cold ... rain ... snow. None of these are words I’m particularly happy to be uttering in this forecast. And while the potential for accumulating snow, at least more than a dusting or so, is low tonight and fairly low (but not impossible) Thursday night, there’s really nothing spring-like about the sometimes wet 40s and 50s we’re expecting the next few days.

Many spots neared or touched the 50-degree mark this afternoon. Though 10 degreees below average, the air felt kind of nice standing in the sun. Hopefully, you caught a few rays because they are looking scarce the rest of the work week. It clouds over late tonight, with a cold rain tomorrow.

A closer look at this late March cold snap

Forecast: Wintry week wears on

The cold keeps coming although it won’t feel so bad with today’s sunshine. Why is spring giving us the “cold shoulder”? The jet stream pattern is currently set up in such a way to continue to transport significant Canadian cold air supply into the U.S. In addition, a series of storms passing to our south from tomorrow through late Friday will keep us cloudy and wet. This chill looks to take a break next week.

Loyal reader Walter-in-Falls-Chuch is well-known for the larger-than-life snow sculptures he has crafted over the years. In mocking tribute to the 0.2” of snow that fell Sunday morning, Walter produced the “sculpture” above. To me, the sculpture is a good metaphor for how this season’s snowfall stacked up to last season’s (2009-10).

Cool technology: Robotic clouds for Qatar World Cup in 2022

When the soccer World Cup comes to Qatar in June 2022, heat ranks high as a concern for the comfort and safety of both players and spectators. The small middle eastern nation’s high temperature averages around 105-110 when the Cup is currently scheduled be played. Enter scientists at Qatar University who say they will develop remote-controlled robotic clouds to float above desert stadiums, blocking the blazing sun and cooling temperatures by up to 10 degrees.

For four consecutive days, temperatures have not escaped the 40s and have been about 10 degrees below average. Our average high is now 60 degrees and I don’t see us reaching that this week - at least through Friday. Not only is it going to be chilly, but also wet at times, especially during the second half of the week And believe it or not, we may still not be completely done with snow...

I wish I had warmer news to bring in the wake of this morning’s wintry brush. Instead, it’s a rather cold week ahead with another chance of snowflakes come early Wednesday morning (did somebody go a little overboard with their snow dance?). Our normal high is around 60 but we’ll have trouble breaking much into the 50s through midweek.

We’ve got another “too cold for spring” day ahead, but there’s at least a little sunshine to be enjoyed for any outdoor activities. Then clouds increase, ahead of a storm system that could drop slight accumulation on the area by the time it departs on Sunday.

We’ve been talking about the chance of snow Sunday since Tuesday, but just today started to talk about amounts. Generally speaking, we’re thinking a dusting to an inch is the best bet. However, some of the model data and NOAA assessments indicate more is possible. So I thought I’d share them so everyone can understand the full suite of possibilities.

It’s as if we turned the calendar back five weeks today. After raw morning rain showers (some snow parts of the northern suburbs and Shenandoah Valley), it’s remained rather gloomy and February-like. Highs struggled to reach the mid-40s and are unlikely to escape the 40s tomorrow through some time next week.

The tornado that touched down in Hempfield, Pennsylvania yesterday was serious. It damaged 90 homes and 30-35 homes are uninhabitable according to the Pittsburgh’s Post-Gazette. The National Weather Service is currently surveying the damage to assess its intensity. But adding some levity to the situation, is the play-by-play accompanying a home video of the storm.

The vagaries of spring are upon us. Temperatures up to 80 one day and down to 30 a few days later are the kind of roller coaster conditions that we can expect for a few weeks. Fortunately for we gardeners this is weather that our plants can stand up to...probably better than us.

Forecast: Spring retreats! Cold & damp win out, snow?

Was it something we said? Temperatures today through the weekend are more typical of February than late March. And then there is that nasty issue of frigid rain possibly mixing with or changing to snow early Sunday. Only a die hard snow lover could hope for that. In any event, a grassy coating is possible which would look pretty since it greened up last week.

Computer models aid Japanese nuclear response

As the Japanese nuclear crisis continues to unfold, the airborne spread of radioactive materials from the stricken reactors at the Fukushima Daiichi power station continues to be a key concern of Japanese and American officials. To help determine the path that any hazardous emissions are likely to take, scientists are employing specialized computer models, known as “trajectory models,” which can take into account factors such as winds and temperatures aloft to determine how high a parcel of air is likely to climb, how far it may go, and where it may be within certain timeframes.

Tomorrow’s colder with a small chance of conversational snowflakes mainly north and west of town. And a cold weekend brings a better, but nowhere near certain, chance of wintry precipitation.

Meteorological vs. astronomical winter

Now that we’re really done with winter (but not necessarily winter-type weather)--both meteorologically (December 1-February 28) and astronomically (December 21-March 20)--I thought I’d compare the two for the 2010-11 winter season, focusing mainly on temperatures. Bear in mind, however, that in the future, when most statistics are gathered, they will refer to the meteorological season, the official standard of the National Weather Service (NWS) as well as some other countries such as Australia and Brazil.

Forecast: Some sun today, rain tonight

With my most sincere regret, I must inform you that springtime takes a significant “time-out” in the days ahead. A change in the weather pattern is coming that side swipes our young spring season with below normal temperatures, frequent rain chances, and maybe even some weekend wintry weather. So today’s highs in the 60s with intermittent periods of sun should not be taken lightly as it may be quite a while before we see that again.

PM Update: Evening showers/storms for some

After a cool morning, afternoon readings soared well into the 60s or near 70 across the area. This is probably warmer than we see for a while, as a front plans to get hung up in the region bringing periods of showers, and eventually much cooler air. Still, tomorrow should feature temperatures near or above 60.

Super Moon over Washington, D.C.

I joined over 100 photographers Saturday evening at the Netherlands Carillon to shoot the super full moon rising over Washington, D.C. The moon rose well to the south of the monuments which was not ideal for framing a classic Washington, D.C. moonrise shot, but the weather conditions were perfect for viewing the moon rising through the sky.

Forecast: Unsettled start to unsettled week

Today marks the first “official”full day of spring (by the astronomical calendar, at least) and it will feel pretty spring-like with 60s and some spring showers. But in case you’ve forgotten, early spring around D.C. can be fickle and that will be the case this week. The weather is not going to get into any sort of rhythm bouncing back and forth between wet and dry. And counter to what you might expect, temperatures generally trend downward rather than upward.

Our trend of falling highs continues. From near 80 on Friday, to the low 60s yesterday, and down into the 50s today. But while we’re cooler than we have been ahead of this evening’s official start of spring, at least we stay dry through the day. Enjoy it while you can, since we head into a more unsettled pattern starting tonight.

UnitedCast: Cool but pleasant opener

If you’re running around on the field this is maybe close to the perfect weather. But in the stands, temperatures falling through the 50s with a bit of a breeze should feel a little chilly at times.

More clouds than expected didn’t prevent highs from reaching the super comfortable upper 70s to near 80. We’ll see a light shower or two at most through early morning before the sun returns for much of Saturday. Weekend temps? Around average.

Europe’s 2010 summer hottest in 500 years

A new study published in the journal Science indicates the extreme magnitude of the heat wave over Eastern Europe last summer probably made 2010 the hottest summer in Europe in more than 500 years.

Super moon Saturday evening

Saturday evening, the biggest full moon since 1993 will rise from the eastern horizon. The moon will appear large because it’s reaching its “perigee”, the closest approach to earth in its orbit. According to NASA, perigree moons are 14% bigger and 30% brighter than moons on the “apogee” side of the moon’s orbit, when it is farthest away from earth. What’s special about Saturday’s perigee moon is that it’s almost coinciding with a full moon, a relatively rare occurrence. Some refer to this coincidence as a “supermoon.”

Forecast: Sunny and becoming warm, lucky us!

Two nice days in a row are going to spoil us. If we keep the clouds at bay, tomorrow’s high could reach the record of 81 National/80 Dulles. A few showers zip through Friday night but skies clear for a delightful Saturday. This gives us perfect viewing for the “super full moon” that rises that night (closest full moon to the earth since 1993). The vernal equinox greets us Sunday with a perfectly seasonable day to mark the astronomical beginning of spring.

Are nuclear reactors vulnerable to solar storms?

The subject of nuclear power plants and solar storms was not what I planned for the second part of the series: Space weather: Are we ready for a solar strike? But, in light of of the nuclear disaster in Japan, caused by loss of external and backup electrical power needed for the reactors’ cooling system, it occurred to me that renewed discussion on the safety of nuclear power ought to include concern about the prospects of widespread and long-lasting outages from solar storms.

The unauthorized release of thousands of emails between several prominent climate researchers in late 2009 - a scandal often referred to as climategate - caused a significant minority of television weathercasters to become increasingly doubtful that manmade climate change is occurring, and that climate scientists and the U.N. Intergovernmental Panel on Climate Change (IPCC) are reliable sources of information, according to a recent study.

Could a tsunami strike the U.S. East Coast?

As we recall the December 2004 tsunami that wreaked death and destruction in Indonesia and watch in horror the current coverage of the disastrous tsunami in Japan, a reasonable question is: Could a tsunami strike the East Coast, including one significantly impacting the Washington D.C. area? The short answer is YES, though with much lower probability and generally not as catastrophic as a tsunami hitting the West Coast.

The “SuperMoon” and the Japan earthquake

On March 19, the moon’s orbit will make its closest approach to Earth in 18 years while at the same time be in full phase. Such a coincidence has been named a “SuperMoon” by astrologer Richard Nolle. As entertainingly chronicled by John Metcalfe over at TBD, Nolle predicts all kinds of weather and natural hazard mayhem, including strong earthquakes, in conjunction with the Supermoon. So the questions that emerge are: 1) Is there any legitimate science linking the Supermoon and extreme natural hazards? and, 2) Did the upcoming Supermoon play a role in this morning’s horrific earthquake in Japan?

Space weather: Are we ready for a solar strike?

Almost two years ago I asked the question, “Do Solar Storms Threaten Life as We Know it?” The answer then and even more so now could very well be a scary “yes” - even within the next few years - as an increase in solar activity coincides with the increasing vulnerability of technology-dependent societies to a powerful solar storm. Moreover, should there be a solar strike capable of causing widespread blackouts and crippling disruptions of satellilte and radio communications, it’s likely there would be little advance notice, and currently there is virtually no capability to shield much of the planet and virtually no planning on the books to recover from the potentially disastrous consequences.

Heavy rains fell throughout the metro region yesterday, with amounts generally in the 1-2.5” range from east to west spanning Prince George’s county and western Fairfax and Montgomery counties. West and southwest of Fairfax county, isolated locations saw around 3” or a little more. Capital Weather Gang’s forecast for 1-1.5 inches in the metro area with locally heavier amounts to the west was pretty close to correct, albeit a little conservative. Where our forecast went wrong was in the snowfall department.

I don’t know about you, but I thought that this past (meteorological) winter, although not particularly snowy around here, was brutally windy on many days, perhaps more so than in many years. But perceptions are often wrong, particular when it comes to the weather, so I decided to do a little research. Was I right or am I just getting older so that I can’t take those “hold-your-hat-down-days” any more?

Should global warming send us to the bunker?

Last Sunday, the Washington Post ran a provocative essay on the front page of the “Outlook” section by climate activist Mike Tidwell, executive director of the Chesapeake Climate Action Network. In it, Tidwell reveals the lengths to which he is going to prepare himself and his family for what he sees as the now inevitable consequences of climate change. For example, he is stockpiling food, testing guns, and invested in an emergency generator - all in an effort to stave off social unrest that he sees coming down the pike due to climate change-related extreme weather events. The essay is surprising - and completely wrong - in two main respects.

For example, he is stockpiling food, testing guns, and invested in an emergency generator - all in an effort to stave off social unrest that he sees coming down the pike due to climate change-related extreme weather events. The essay is surprising - and completely wrong - in two main respects.

Forecast: Sunday soaker, then seasonable

Anyone complaining of drought should rejoice with today’s solid soaking. An inch or more of rain is possible for most, and a Flood Watch is in effect for most of the area today. Starting tomorrow we’ll enjoy a few seasonable days (though tomorrow is fairly windy) before another system approaches for the second half of the week.

PM Update: Friday temps inch upward

Looking out the window this afternoon could easily mislead those seeking insight into the weather. Skies were just as sunny as yesterday, but temperatures around 25 degrees colder. After a chilly night, temps swing back up tomorrow - roughly midway between today's upper 30s and Wednesday's low 60s.

Weather image of the day: Greek crescent moon

The beautiful image above of a waning crescent moon over the Poseidon Temple is described by photographer Elias Chasiotis: "On the morning of January 1, 2011, I visited Sounion, Greece hoping to celebrate the start of the New Year with a glimpse of the waning, crescent moon rising over the ancient Poseidon Temple. Just before the start of morning twilight, the Moon's crooked grin appeared and seemed to strike a balance atop the approximately 2,500 year old temple."

PM Update: Cold front to bring fresh chill

Hope you enjoyed today's warmth as tomorrow you'll probably need to bundle up! A dry cold front moving through the area sends temperatures lower and winds temporarily higher. Pretty much everyone should expect a freeze tonight, and temperatures only rising into to near 40 during the day tomorrow despite plenty of sunshine. CWG's Detailed Forecast

Global warming & snowstorms: not a yes or no link

A day after the Union of Concern Scientists (UCS) - a non-profit environmental group - announced "Climate Change Makes Major Snowstorms More Likely", USA Today's Weather Editor Doyle Rice published an interesting story on possible linkages between U.S. snowstorms and global warming. Unfortunately, however, the headline USA Today chose to accompany the story "Scientists: Global warming to blame for big U.S. snowstorms" is scientifically dubious and grossly misleading.

PM Update: Sunny Wednesday warm-up

Chilly winds from the northwest held temperatures below average for the first time in six days today. Mid-to-upper 40s were all the March sun could muster on its incipient day. But after a clear and a cold night, the absence of north winds help temps bounce back into above average territory tomorrow. CWG's Detailed Forecast

Recent March weather: In like lion, out like lamb?

The saying goes: If March comes in like a lion, it will go out like a lamb. But how has that saying held up over the last decade?
