Plan Ahead for Slick Spots This Evening but Light and Widespread

WINTER WEATHER ADVISORY NOW CANCELED FOR A GOOD PORTION OF THE REGION

ZZZZZ

Not impressed. Yes, I can hear the keyboard typing with comments now but this is how the weather rolls in D.C. –once you think you nailed the forecast – things have to go ahead and change. We always have to keep an eye on the latest data because of this fact (and this is also why we wait just a little while longer to put out snow totals).


I’ll just come out and say it – although there will be slick spots out there this afternoon and tonight, anything we get will be fairly widespread and pretty light. We are really dry out there and temperatures are rising. The precipitation will be delayed slightly because it is evaporating before it even hits the ground. Considering it will take longer to moisten the atmosphere, temperatures will continue to rise.

ZZZZZ

I would still plan ahead for some light icing during the evening commute and use caution but I believe a good majority of the roads around the D.C. metro area and south will just be wet with some light rain. However, please watch for the regular spots – bridges, overpasses, underpasses and exit ramps for a better chance of some light glaze. (Don’t worry – the StormWatch7 team will continue to update through your evening commute to get your home safely).


Temperatures will rise overnight and we will have some spotty rain showers during the overnight hours. More scattered showers will move in through the day tomorrow as temperatures move on up to the lower 50s in spots! Rain could be heavy at times which could lead to some flooding around the region (rain plus melting of the existing snowpack).

We are still on point to see some snow/sleet move in on Wednesday after midnight as a cold front will unleash more arctic air upon us for Thursday. In fact, temperatures drop on Thursday from the 30s and into the 20s (winds will pick up as well making it feel like the teens and single digits). Any sleet will then turn to snow showers and those are forecast to hang around for much of the day on Thursday which means accumulating snow around the region. It is too early to push out snow totals so please don’t buy into the hype on the internet just yet (look how quickly things changed today). If I had to go out on a limb right now, I would count on delays and cancelations on Thursday as the way things look now. However, we will update you with snow totals early Wednesday morning with all the latest information!
