PM Update: Rain arrives Wednesday afternoon

By Jason Samenow

The beautiful sunshine of the last two days is now fading as high clouds arrive ahead of the next storm system. Thanks to sun earlier in the day, highs still managed to reach near 50 today. Tomorrow turns gray, with rain shower chances increasing in the afternoon.

Through Tonight: Skies are partly cloudy overnight and temperatures remain chilly with cold high pressure to the north. Lows range from near 30 in the colder suburbs to the mid-30s downtown.

Tomorrow (Wednesday): There may be enough breaks in the cloud cover to allow for a colorful sunrise, but skies gradually become overcast during the morning. Well to the west and northwest (i.e. western Loudoun and western Frederick counties), a little precipitation could break out (20% chance) in the late morning in the form of rain and sleet. By the time precipitation reaches the closer in suburbs mid-to-late afternoon (60% chance), precipitation is most likely in the form of light rain (the heavier rain is most likely Wednesday night and especially Thursday) with temperatures well into the 40s. East of town, rain may hold off until after dark.

Climate change science hearing: The House Energy and Commerce Committee today held a hearing on the science supporting EPA's greenhouse gas regulations. Scientist/blogger Michael Tobis aggregated some of the most telling quotes from the hearing, and summed it up this way: "Issues duly ducked, many person-hours wasted. No minds changed/ A few good quotes here and there, and a little more scary data to ponder. " Blogs featuring transcripts of expert commentary during the hearings are available at Climate Central (featuring CWG's Andrew Freedman) and Science magazine.

Have you thought about getting errands or outdoor plans done tonight, prior to our rain tomorrow night? Might be worth thinking ahead...

spgass,

how much of that 5.5" of snow is still on the ground?

i'm still shocked that you picked up that much snow...that (5.5") would rival commutageddon in many places.

maybe you should shovel it all up, put in in the back of a pickup truck, haul it to falls church, and dump it in walter's front yard ;-) i know he'd be very appreciative of that...

jason,

the 18z gfs just came in and suggests a very rainy scenario for dc...up to 3".

http://mag.ncep.noaa.gov/NCOMAGWEB/appcontroller?prevpage=Param&MainPage=indexℑ=&page=Param&cycle=03%2F08%2F2011+18UTC&rname=PRECIP+PARMS&pname=precip_p48&model=GFS&area=NAMER&cat=MODEL+GUIDANCE&areaDesc=North+America+-+US%2C+Canada%2C+and+northern+Mexico&fcast=03%2F08%2F2011+18UTC+057HR

but the 18z nam shows as little as 1".

http://mag.ncep.noaa.gov/NCOMAGWEB/appcontroller?prevpage=Param&MainPage=indexℑ=&page=Param&cycle=03%2F08%2F2011+18UTC&rname=PRECIP+PARMS&pname=precip_p48&model=NAM&area=NAMER&cat=MODEL+GUIDANCE&areaDesc=North+America+-+US%2C+Canada%2C+and+northern+Mexico&fcast=03%2F08%2F2011+18UTC+057HR

at this point, which of the two scenarios is most likely? or would a compromise between them be probable?

walter,

considering our dimishing snow chances, i'm beginning to think you should seriously consider taking up mud sculpting ;-)

@BobMiller2

I'd go with a compromise but leaning toward the GFS. The NAM had some weird solutions for Sunday's event at this range.

The skies were clear for me to view the space shuttle and the space station fly overhead. Did anyone else see them?

Anybody catching the radar down in the gulf right now? A double stream of moisture is being sucked up from the gulf waters. Looks rather impressive.

dc's record snow for today's date is 5.8" in 1911.

bob,
those mud things are really cool. i love the idea of planting a garden on one - like a chia pet. you can see from those shapes (hippo lying down, face) that you are limited a lot by the heavy, slumping nature of mud... much like sand, i suppose.

(btw, when posting those model links from the new model page, there's a link listed at the top of the image that's much shorter than that loooong crazy address found in the address bar.)

Bob, I live at only 600 feet and SP is at 1800 feet, but when we drove over the Blue Ridge (1200 feet IIRC) there was an inch or two of snow left in the shady areas. More complete snow was visible on the mountain, so I'm guessing he has 3 inches left in the shade.

Walter,

thanks for the tip about the links...I didn't realize just how long they were until I posted them.

Eric,

thanks for that info about the snow. You guys in Warren co. get all the good weather :)
