A Winter Weather Advisory has been issued for MoCo from 7pm this evening until 10am Monday. 1-2 inches of snow and less than a tenth of an inch of ice is expected. I expect something to come out tonight that will either extend this or add something for Monday into Tuesday.
There have been changes with almost every run of every model. As it looks now, some winter precipitation will enter our area at some point between 8pm-11pm tonight and will continue into the morning before a flip to rain later in the morning.
In these images from NBC4 and WUSA9 (my apologies to Melissa Nord for the screen grab 😳😊), you’ll see that NBC expects about half of MoCo to be in the “most icy” zone and WUSA has about a third of MoCo in the “slick and dangerous” zone for the morning commute.
ABC7’s Alex Liggitt said he’s “not really expecting much, but enough for some travel disruptions into the morning commute” so not everyone thinks this will be a complete mess.
This is another situation where we aren’t expected to get a lot of precipitation, but the timing makes for another difficult decision for school systems.
I expect to have another update tonight, but check out the free iOS MoCoSnow app for predictions that include specific percentages for school delays and closings (updated as necessary throughout the day).
We’re also going to be doing this again tomorrow night because a similar situation is expected Monday night into Tuesday…possibly a bit icier than tomorrow morning!
MoCoSnow Prediction for Monday, 2/11 (Rating system is available in the “rating system” tab of the website):
If there’s wintry precipitation into the morning, I can’t see schools opening on time. If temps remain colder for a little longer, this can easily lead to a whole day off.
