mattie g Posted January 30, 2014 Share Posted January 30, 2014 At least.. plus new snowcover > old snowcover it seems. IAD had a relatively warm low considering. Yup. We got down to 8.6, but that's with 0-3" of snowcover in my neighborhood (depending on shade, etc.). I'd imagine that Dulles is similar, so the lack of uniform, deep snowcover really "hurts" in these situations. To be 10+ degrees warmer overnight than places on the Eastern Shore, SE VA, or down in eastern NC is pretty wild. Link to comment Share on other sites More sharing options...
Bob Chill Posted January 30, 2014 Share Posted January 30, 2014 New snow is better because it has much less time to absorb heat from the raging sun angle Link to comment Share on other sites More sharing options...

jonjon Posted January 30, 2014 Share Posted January 30, 2014 -16 here this morning. That is 12 days with the low below zero and one with the high below zero this month. Link to comment Share on other sites More sharing options...
Symblized Posted January 30, 2014 Share Posted January 30, 2014 Perhaps, but that warm day really did a number to the formerly almost frozen Baltimore Inner Harbor, and these last two cold days have not led to a recovery. And of course the ice is back in force today. Link to comment Share on other sites More sharing options...
WEATHER53 Posted January 30, 2014 Share Posted January 30, 2014 Great data on the cold. I hope we can get 6" here soon to death knell DCA as being accurate. When all the roads, buildings, parking lots and ground are covered with snow, when most all vehicles are covered or not running, when the Potomac is froze or at 32, then there really is not UHI. All that is exposed at that point are the sides of buildings, everything else is rendered the same by 95% snow coverage. If, at that point, DCA is still 5-10 degrees milder than everyone else then it would be indisuptable truth of the errors of where their senors are located and how their information is culled. The elevation difference is worth about 1 degree versus BWI, Andrews. Link to comment Share on other sites More sharing options...
Ian Posted January 30, 2014 Author Share Posted January 30, 2014 Nights like last night are prime ones to get screwed by UHI. I noticed the wxbug stations were as warm or warmer than DCA around midnight at least. Link to comment Share on other sites More sharing options...

I noticed the wxbug stations were as warm or warmer than DCA around midnight at least. yes and even snowcover wont mitigate it....before it got built up IAD used to go below zero with more regularity....IAD had the same low as FT Belvoir...does that mean IAD's sensor is messed up too?..IAD is in a perfect radiational bowl Link to comment Share on other sites More sharing options...
WEATHER53 Posted January 31, 2014 Share Posted January 31, 2014 Clouds came in very fast, temp shot up from 15.5 to 17.9 For DC guy I giggle when saying "shot up from mid teens to upper" Link to comment Share on other sites More sharing options...
bluehens Posted January 31, 2014 Share Posted January 31, 2014 Some pictures of the very top of the Chesapeake Bay from my in-laws backyard. They currently have 3 barges and 4 tugs stuck in the ice in the shipping channel. Been there since yesterday. In one picture you can see the Turkey Point Lighthouse on the far left side of the image.

WEATHER53 Posted January 31, 2014 Share Posted January 31, 2014 Tropical side will be fun this season. Posting like "Glad that season is finally over" are recieved so well but what is good for winter weather is also good for tropical weather.
