Pencil Prediction for Friday 12/13 (Freezing Rain)

December 13, 2019
MCS Staff

There’s a Winter Weather Advisory just to our north and west in Frederick and Loudoun counties.

The advisory is for up to a tenth of an inch of freezing rain that could lead to very slippery sidewalks and roads…but let me stress that MoCo is not included in this advisory.

There is a chance, however, that spotty freezing rain makes it over to us causing some slick spots. Because it’s freezing rain, the chances of a delay are upped a little higher than just one pencil, so we give this one 1.5 Pencils.

Below you’ll see an image from the free iOS MoCoSnow app. For now, the only feature is the specific % for school closing and delay predictions.

Our Android app is coming this season, but we’ve had a slight delay so I don’t know exactly when.
