MN Transplant Posted February 21, 2011 Share Posted February 21, 2011 Ah, so now there's an obs thread. Copied over from the other one. Winds switched to the north IMBY a little over an hour ago, and the temp has fallen from 51 to 44. DCA went from 53 to 49. I don't think any of the models, including the HRRR, had us going N until noonish. Link to comment Share on other sites More sharing options...

aldie 22 Posted February 21, 2011 Share Posted February 21, 2011 down from earlier this morning? Down from the 39 you posted in this thread...those obs are from JYO...you know it's chilly when that thing registers low Link to comment Share on other sites More sharing options...
Stormpc Posted February 21, 2011 Share Posted February 21, 2011 Pretty stark temp contrast in NOVA. Dulles down to 39 while just 13 miles or so due south at Manassas airfield its 54. Will be interesting to see how far south that push can make it. Link to comment Share on other sites More sharing options...

Bob Chill Posted February 21, 2011 Share Posted February 21, 2011 39 IMBY. Wind is N here too. Column saturated so no evap cooling expected. Nice to see the temps where they are and the N winds. LWX made note of the tricky temp forecast to in their morning AFD. If we end up in the U-30's L-40's today then it won't take much at all for the surface to go below freezing later on. Overperformer on the way? Link to comment Share on other sites More sharing options...
WxUSAF Posted February 21, 2011 Share Posted February 21, 2011 DCA now down to 45, IAD to 40. I can't believe that DCA was up to 12C just a couple hours ago! Wouldn't be hard to place this front on a map. The thoughts of upper 50s to near 60 today are laughable now. We might have already hit our highs for the day.

BlizzardNole Posted February 21, 2011 Share Posted February 21, 2011 Holding at 38 in Germantown...those are some quick drops at DCA and Dulles. Hard to believe we hit 76 on Friday! Today is going to be a far cry from the expected 60-ish (as of a couple days ago). We might not get out of the low 40s. Link to comment Share on other sites More sharing options...

Ellinwood Posted February 21, 2011 Share Posted February 21, 2011 MY temp has fallen from 53 to 48 in the past 40 minutes. Looks like my temp call from yesterday will be a big bust. Big temp busts for almost everyone across the board A good thing for snow lovers (and anyone who went straight MOS) for sure. We'll have to see if it holds or adjusts N/S, all 3 of which are still possibilities today. Oh the fun! Link to comment Share on other sites More sharing options...
clskinsfan Posted February 21, 2011 Share Posted February 21, 2011 We had a little snow last night. No Accum. I was not expecting to wake up to a WSW this morning though. LWX seems to like my chances out here. A bit extreme I think. Tonight: Rain, snow, and sleet, becoming all snow after 1am. Low around 26. East wind between 11 and 14 mph. Chance of precipitation is 100%. New snow and sleet accumulation of 4 to 8 inches possible. Tuesday: Snow likely, mainly before 7am. Partly sunny, with a high near 32. North wind around 8 mph. Chance of precipitation is 60%. New snow accumulation of less than a half inch possible. Link to comment Share on other sites More sharing options...

Bob Chill Posted February 21, 2011 Share Posted February 21, 2011 NAM colder and wetter. Boudary could set up further south and put central MD and NOVA in the sweet spot for lift. Surface already way colder than modeled in those same areas. Link to comment Share on other sites More sharing options...

Herb@MAWS Posted February 21, 2011 Share Posted February 21, 2011 Looks like the mid-AM LWX update for HoCo area lowers max temps from U40s to M40s and ups snow forecast from 1-3 to 2-4. Link to comment Share on other sites More sharing options...
Bob Chill Posted February 21, 2011 Share Posted February 21, 2011 Raining at Wisp. Boundary has an interesting orientation. Looking at the NAM 850 maps you can see the nice bend around the E side of the apps/blue ridge. Warmer air at the surface and aloft out to the west. Crazy how all the pieces are coming together for a mostly to all snow event here. Link to comment Share on other sites More sharing options...

clskinsfan Posted February 21, 2011 Share Posted February 21, 2011 Well I am at 37.7 here. I guess my temps should fall for the rest of the day with a north wind. Looks good for mostly snow here now. DP is at 34. Link to comment Share on other sites More sharing options...
Bob Chill Posted February 21, 2011 Share Posted February 21, 2011 Any bets from you as to when you see the changeover? Hard to say because I only see the 6 hour panels. If I had to guess it would be around 5-6pm? If you look at the 12 and 18 hour 850 panels of the NAM it happens sometime in between. Once it does it going to snow pretty darn hard out that way for 6 hours or so. Edit: I did the math wrong. Probably around 8pm or so. Link to comment Share on other sites More sharing options...
