Season Finale :(

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

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)

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.

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.

Elevation made a big difference for the temps in those two. 2/24/05 was about 5 degrees F colder during the daytime at DCA compared to 2/28/05. But at IAD, that difference was only 3 degrees F.
