yoda Posted March 20, 2018 Share Posted March 20, 2018 Afternoon AFD from LWX -- I grabbed the most important part of it for tonight into tomorrow: Things change considerably late tonight. Both the surface and upper lows will be strengthening as they head east and northeast toward us, and as divergence and isentropic lift increase late tonight, snow, heavy at times, will overspread the region later tonight from west-southwest to east-northeast. Have started warning/advisory in areas without current headlines just before this heavier band of precip is expected to move in. One thing if note is that a warm layer could remain aloft (as depicted by various guidance such as the NAM) into the overnight, so the steadier precip may start as a mix of snow and sleet before transitioning to all snow. As the low continues to strenghten during the day Wednesday and gradually gets captured by the upper low, heavy snow could potentially continue much of the day across the CWA, and our totals could very well be conservative. Would not be surprised to see additional significant revisions to the forecast even at this late hour. Winds will be northeast to north gusting 20-25 mph, so not a blizzard, but perhaps a factor for severity of conditions. Accumulations will be QPF and ratio dependent, with our current graphic including the snow which fell today. Thus, highest totals for the whole event are still expected for northwestern areas, with totals locally over a foot most likely in these areas. However, given the intensity of the precip band expected to cross the region on Wednesday with the second low, would not be shocked if some places that haven`t seen much so far could still manage to get close to a foot. Temps through the next 24-30 hours will continue to be near or a bit below freezing, with not much change overall. Link to comment Share on other sites More sharing options...

cae Posted March 20, 2018 Share Posted March 20, 2018 We had some brief mixing with snow this afternoon, but other than that it has been sleet mixed with freezing rain all day. Over 0.5" of sleet on the ground so far, with pellets frozen together into a hard sheet of ice. Link to comment Share on other sites More sharing options...

Snowman. Posted March 20, 2018 Share Posted March 20, 2018 Was under some yellow returns for a bit here in Sterling. Flake size was huge. Whitened the ground nicely. Link to comment Share on other sites More sharing options...
clskinsfan Posted March 20, 2018 Share Posted March 20, 2018 It just wants to snow here today. According to radar I should not be seeing any of it. Yet it is certainly falling. Link to comment Share on other sites More sharing options...
ErinInTheSky Posted March 20, 2018 Share Posted March 20, 2018 Grass shouldn't last much longer here. Snow is really coming down in Gaithersburg. If I get 2" by 6:00, the Euro will have verified the first frame for me. Could happen if you saw how much was coming down, will be very dependent on banding.

aldie 22 Posted March 20, 2018 Share Posted March 20, 2018 Almost looks like a pivot to the moisture stream...hope the light snow continues here as it has whitened up just about everything but main roads. feels like a winter day now Link to comment Share on other sites More sharing options...
ErinInTheSky Posted March 20, 2018 Share Posted March 20, 2018 Anyone north of the beltway, my bet is the next band gives all of you snow too. I was sitting under FZRA/sleet for the longest time but once it started snowing it just hasn't stopped. Link to comment Share on other sites More sharing options...

WolfStock Posted March 20, 2018 Share Posted March 20, 2018 Looks like we're about done for a few hours in Leesburg. Just "snow drizzle" if you will, with radar showing nothing with a couple of hours. First part has been a bit of a bust - only gotten about half inch of sleet/snow mix in this first part of the storm. One one point the forecast was 8-10" today; now down to 3-5". Sigh.

southmdwatcher Posted March 20, 2018 Share Posted March 20, 2018 Sleet has been falling mixed with rain for several hours now, but becoming more sleet than rain. Light precipitation is keeping accumulation to a minimum. There is a trace coating on cars, driveways and elevated surfaces. I measured 0.23" of rain at 8am and then an additional 1.2" at 3:30pm with sleet accumulating on top of the Cocorahs gauge. Lots of QPF for this event. Location is halfway between Waldorf and LaPlata Link to comment Share on other sites More sharing options...
ErinInTheSky Posted March 20, 2018 Share Posted March 20, 2018 Getting close to an inch in Gaithersburg. If I can break 2", then the first 6 hours of that awesome Euro run verifies for me. Link to comment Share on other sites More sharing options...
