A Winter Weather Advisory has been issued for Montgomery County on Tuesday 1/29. For NW MoCo, it runs from from 6:00 AM until 9:00 PM. For C/SE MoCo it runs from noon until 10pm. 1-3 inches of snow is expected.

We may see some snow or sleet in the morning tomorrow, but I don’t suspect that the earlier stuff (if it falls) will be enough to cause a delay or closing. We’ll see temps in the upper 30s around noon, so we’ll likely see some rain before it changes over to snow in time for the evening commute (as seen in the photo below, by NBC4).

Slush is expected to start accumulating in the late afternoon into the evening. With anything that has fallen expected to freeze as temps drop into the 20s around 8/9pm.

Pictured you’ll see projected snow totals from WUSA9, The National Weather Service, Capital Weather Gang, and Justin Berk.

WUSA9 and the National Weather Service have us in the 1-3″ range. CWG has 2/3 of MoCo getting a coating to 2″ and 1/3 getting 1-3 inches and Justin Berk has about half of MoCo in his “pink zone” which means morning ice and 2-4 inches of snow and the other half in the blue zone, which means morning ice is a possibility and 1-3 inches of snow is expected. Berk is the most optimistic about MoCo’s chances for winter weather.

I don’t think there’s much of a shot at a delay tomorrow, so for the 1/29/19 iOS MoCoSnow app prediction the delay option means early dismissal.

Fairfax County has already announced an early dismissal tomorrow, and it’s possible we see more counties announce the same.

MCPS put out a message on their website letting us know to expect a decision tomorrow. I think an early dismissal is in play.

Pencil Prediction for Tuesday, 1/29:

For an early dismissal (not delay). Check out the rating system tab for a refresher on what the pencils mean.

We’ll discuss Wednesday tomorrow 😊

    The weather apps are saying that it should be a wintry mix/freezing rain/snow for Damascus the morning and the entire day. Even though temps are below freezing during the day, could it still raise the possibility of a closure?

    I see a chance of snow showers on Friday morning. Any chance that will affect schools?

    And I noticed this weekend and the beginning of next week will be a bit warmer. Will that reduce the possibility of nor’easters for the start of February?

      Yes there’s a chance. We have about 3 snow chances before Feb 12 as of now. Could happen, could be nothing.

    I agree mostly, but the way you say it in your post it feels like it should be more 50% ish. Why 40% if you say you think a early dismissal is on line?
