January 20 Weather Early Flurries Chilly Inauguration And Next Winter Event Early Next Week

Wednesday January 20 2021

A series of cold impulses is underway, and they have brought a few flurries and snow showers early this morning. A burst of snow is still possible, with this cluster dropping out of PA and across Hagerstown at 7 AM. This could drop a quick coating in parts of Frederick and Carroll Counties. We will watch this into Mt. Airy and perhaps parts of Montgomery and Howard Counties and near Washington DC between 8 AM and 9 AM. Then clearing and just chilly for the rest of the day.

The next surge of colder air will arrive by Friday and sustain itself for a week, just in time for the next winter weather system. The timing appears to be Monday to Tuesday, as we will take a look at it below.

Looking Ahead: Winter Event Early Next Week

It is too early to get too excited and call this a storm. While it is looking better, we still have a 5 to 6 day time frame and a diversion of model plots.

I will explore more in my next report, but here is the quick version:

If you want snow, root on the European and Canadian Models. If you want a smaller system passing south, root on the GFS.

This solution shows snow beginning on Monday, with a snow/mix then evolving into a colder system for the region.
