A Little Icing Inland Tonight Larger Snow And Ice Storm Thursday

Monday February 15 2021 Afternoon Update

The historic winter storm and arctic blast continues to rage across the deep south and Ohio Valley. The snow drove to the. Texas border with Mexico, and is nor driving up the Ohio Valley.

Our region is on the edge of this pattern, with just and slight icing event inland this evening.

Over the weekend I mentioned that the snow and ice in place would refrigerate the atmosphere and we might trend colder. This storm is just too strong, and wait until you see the warm air that pushed into part of Maryland tomorrow. The cold air will return Wednesday, and set us up for our taste of this action on Thursday.

 

This storm will ride to our west and bring in mild air Tuesday, but the cold air returns Wednesday keeping much of Maryland near or below freezing again. That sets the stage for our prime event this week:

Ever watch an 18-wheeler come down a 3 lane highway from far away?
You know it’s a big and getting closer, but not sure which lane it’s in…until it gets closer.

Snow and Ice Storm

This is the GFS Model. It had been warmer than the Euro I’ve been showing you.  It is falling in line with snow and ice, and I think we need to watch for a track shift east that could still trend even colder.

How much snow?

Plan for a few inches and impact during the day, before the change over to ice.  More will likely fall in our northern counties, but we need to see how tonight’s storm and cold air to follow Wednesday behaves.  That will help present the storm track and extent of snow and ice.
