Forecast and Prediction for Tuesday, January 7th, 2020

Temperatures have been warm and they’ll get warm again as we approach the weekend, but anyone who has been in our area for a winter or two should know how often and quickly our weather fluctuates.
It’ll be cold overnight, with temps dipping into the mid 20s before nearing 40° around noon tomorrow as the rain moves in. They’ll dip a few degrees as rain turns to snow around 1 or 2pm tomorrow afternoon.
This is a quick moving storm and will only last a few hours. The heaviest snow will likely fall around 4pm and it should be out of our area by about 7pm.
Most news outlets expect between a coating to 2 inches of snow, but some models suggest we could see 3 or 4 (less likely than what the maps show). Maps courtesy of the National Weather Service, ABC7, WUSA9, and Capital Weather Gang.
Snow will make roads wet at first, but things could get a little slick if enough falls.
Pencil Prediction: 2 Pencils (with early release taking the place of delay for this one). I expect after-school activities to be cancelled.

    Come on MoCoSnow, there is a least 3 pencils and I’ll tell you why. 1) The timing of this storm is just too close to when many schools get out. Think about the elementary school students who get out at 3:30 or some at closer to 4. MCPS does not want to risk these kids’ safety, especially with the recent bus accidents in the area. 2) There is a big boom potential here. As my friend Al has explained in earlier posts, there will be lots of stickage and slippage caused by this storm. It has been very cold out, and the snow will definitely stick to sidewalks and roads. I hate to disagree with you MoCoSnow, but there is serious potential with this storm.

    Come on now Moco Snow. This has gotta to be 3-4 pencils. If there’s a 1-3 inch snow accumulation prediction, that could lead to 1-3 days of no school. Now, that may be a little unlikely but the algorithm speaks for itself. With stickage and slippage always at issue, there’s a strong chance of no school. But hey who am I to say, I’m only planning on majoring in weather at the top weather University in America.

      Oh my! The top weather school in America? What a prestigious aspiration! If only their were actually knowledgable people who knew what they were talking about- oh wait, the MoCo Snow people. Shut up

      dang… you would think that a student of your caliber would know that likely events are more likely to occur than unlikely events.

      i can’t comprehend ur comment because it’s just so…. wrong

    Are after school activities are definitely canceled?

    • Alex Tsironis on January 7, 2020 at 3:50 am

      Nothing is definite unless it’s announced by MCPS.

    I need a Early Dismissal. A winter weather advisory was just issued too!

  6. JustBeANicePersonPlease on January 7, 2020 at 3:19 am

    With how indecisive MCPS is, two pencils is definitely appropriate for our county, whether it’s dangerous or not. Also, if the storm is hitting quite close to the time where schools get out, the odds are that MCPS will tell the county to suck it up and deal with it. That is, if nothing sudden happens that causes more snow than anticipated. Thank you, MoCoSnow, for putting out your thoughts on tomorrow.

    I think there will be an early release(2.5 snowflakes) because there could be a snow squall warning. Why? If you read the advisory more carefully, the advisory says “Snow rates around one inch per hour are possible with visibility around one-half mile at times.” This could lead to a snow squall warning, which is near-blizzard conditions for a short period of time. Also, as other people have said, 1-3 inches of snow falling in 6-7 hours means that the snow will fall fast, which means that even if temps are 32 and will result in the snow sticking. This will cause roads and sidewalks to become slick and slushy and will become dangerous for students, especially walkers and elementary school kids. 1 inch is enough to cause slick spots, but amounts possible that is 3 times higher than that? That will create black ice, slush, and snow-covered sidewalks/roads, especially in upcounty, where it will be a mess. There is a hugely significant difference in snow accumulation on the ground between 1 PM and 3 PM, so an early release will really make a difference in the student’s safety.

      *above 32 degrees, the snow will fall fast enough to stick(due to the falling outside temp and the snow making the surface temps 32>
