ers-wxman1 Posted March 24, 2014 Share Posted March 24, 2014 Wonder if the various DOTs will bother treating the roads in advance of this storm, given their blown budgets and marginal temps. There's so much sand and whatnot on the roads already that they shouldn't need to. I noticed solution on the roads when I left work a bit ago... 606 in Sterling Link to comment Share on other sites More sharing options...
ers-wxman1 Posted March 24, 2014 Share Posted March 24, 2014 I'm going to try and somehow measure an honest inch... Just 1 inch will give us 50" at LWX/IAD. Impressive if we can get it. Link to comment Share on other sites More sharing options...
needbiggerboat Posted March 24, 2014 Share Posted March 24, 2014 Just 1 inch will give us 50" at LWX/IAD. Impressive if we can get it. In some ways it would be more impressive than 9/10...it's tough to get the sheer number of measurable snow's we've had this season. Link to comment Share on other sites More sharing options...
Deck Pic Posted March 24, 2014 Share Posted March 24, 2014 Yup, I agree. For comparison, I checked 3/14/99- best ob at DCA was 3/4 mi visibility at 34 F and a period of 1 mi visibility at 33 F. Just that difference meant practically no grass accumulations. Of course, 3/30/64 was a different beast-- 0.4 mi at 31 F (8 am), 0.2 mi at 30 F (9 am), and 0.5 mi at 29 F (10 am). 1st pic - 6:30 pm on 2/28/05 downtown, then 7:30 2/28 in Mt pleasant, and then same park afternoon of 2/24/05..subtle temps differences make a difference....2/24 actually stuck to downtown roads and pavement at times during the day (see final pic) Link to comment Share on other sites More sharing options...
Sparky Posted March 24, 2014 Share Posted March 24, 2014 Sure is a cold lead in. My high was 35 low 17. It might actually accumulate a bit on hard surfaces tomorrow. Link to comment Share on other sites More sharing options...

CAPE Posted March 24, 2014 Share Posted March 24, 2014 WPC has a low risk of 4 inches from SW-VA to central MD and upper Delmarva into SE PA, mostly from the early-mid morning deal apparently. Does the Euro show this feature or is it just the GFS? Looking at the NAM, Hi-Res NAM and Canadian models, its not as impressive, and they seem to weaken that forcing as it gets into DC and points NE, and focus the stronger frontogenetic forcing over lower DE and into SNJ into the afternoon and evening with the coastal.

mitchnick Posted March 24, 2014 Share Posted March 24, 2014 Gfs gives dc 3 times more QPF than Boston and we know what happened after the last winter where beat the pants off of Boston...3 yrs of misery to borrow a phrase "curb your enthusiasm" Link to comment Share on other sites More sharing options...
mitchnick Posted March 24, 2014 Share Posted March 24, 2014 there's some cold air aloft with that u/l low....dynamic/energetic some crazy shiat may happen tomorrow which could surprise all of us (I hope!) you can see it here on this radar....very T'storm -like signature to those echos http://radar.weather.gov/Conus/full_loop.php Link to comment Share on other sites More sharing options...
CAPE Posted March 24, 2014 Share Posted March 24, 2014 Surprisingly, JB2 all in with the canadian and a delmarva spring crush job. It would be the lower Delmarva, mostly southern/eastern DE, and coastal NJ if the Canadian and NAM models are correct. Link to comment Share on other sites More sharing options...
needbiggerboat Posted March 24, 2014 Share Posted March 24, 2014 I'll just be happy to see snow falling on March 25th Would be 4th time for me since moving to the area (78, 90, 13, and 14 if teh model is right). Getting ho hum. Link to comment Share on other sites More sharing options...

CAPE Posted March 24, 2014 Share Posted March 24, 2014 I'm not giving up hope for a surprise tomorrow. Who knows....never say never. Based on what the models are showing, its not going to be that surprising. Some places are going to get a few moderate to heavy snow bands and maybe a few inches. Models differ somewhat on exactly where and when that would occur. Link to comment Share on other sites More sharing options...

Bob Chill Posted March 24, 2014 Share Posted March 24, 2014 The only missing cylinder in the engine it timing. Cold night and low dews on tap will offset that some but best rates near noon are a bit of a bummer . If we could have had a 4am onset schools would be closed.
