Interesting times ahead...

I cover a lot of ground in today's edition of the Carolina Weather Video. Anything from a nice afternoon today, some Tennessee Valley snow later this week, more arctic air over the weekend, winter weather possibilities in the Carolinas early next week, and the pattern as we march toward February. Give it a look....



We began our Wednesday with lots of fog and clouds, but this should actually wind up being one of the nicer afternoons we have had thus far this winter. Highs will top out in the 50s, and we will see lots of afternoon sun.

This is a quick-hitting pattern, and this mild weather will not stick around. A low pressure area and its associated arctic cold front will move through the Carolinas Thursday night. East of the mountains, any precip (and that will be limited) will be in the form of rain. To the west, this will likely be a light snow event through the Tennessee Valley. The amount of precip is limited though, so don't look for huge snow totals.

Much colder air will again flow in here Friday, and we might see some Piedmont spots struggle to hit 40 Friday afternoon. Snow will be flying again Friday morning in the mountains.

It will be cold for the weekend again with many spots in the 30s for highs Saturday and low to mid 40s at best Sunday. Lows will drop into the lower 20s and upper teens.

System early next week...

We are dealing with lots of moving pieces here, but this sure has the overall look of one of our cold air damming winter weather events. Frankly, at this point, the European, Canadian, and UKMET models are all really in quite good agreement with one another. The GFS is a little slower and weaker overall. But just look at this panel from the UKMET....1039mb high near the NE, and a low in the northern Gulf. That always smells like trouble.
To me this has the looks and feel of a potential ice event across parts of the region....maybe a snow to ice deal in the NC favored damming regions.

Keep in mind we are firmly entrenched into the 'potential' category here.....this could vanish in future model runs as, like I mentioned, we are dealing with lots of moving pieces. But it has my attention.
