February 10 2021

We have a very busy stretch of weather starting tonight and going to the weekend. It does look like we are in a pattern for quick movers, mostly hitting us at night, and ending in the mornings.  If you have Faith in the Flakes, this is your weather pattern.

The Winter Weather Advisory in place covers most of our region for Part 1 or Event 1, ending Thursday morning. This will be snow.  Part 2 will be a second event Thursday night into Friday morning, with snow impacting southern areas more.   Then event 3 arrives Saturday night into Sunday with more ice, which may impact Valentine’s Day plans.

This does not look like much, but it is expected to enhance tonight when it reaches us.  There will be a second part from the energy along the southern part of that front.

Notice the wide range of guidance here.  It is important to not just look for the highest numbers… those don’t always play out.

Temperature Outlook: Sustained Cold

You may notice the extremely cold air has fluctuated out of this plot.  That is all based on the upper air pattern. The important part here is the sustained cold near or below freezing that remains in place.
