Rain chances and cold air for second half of this week, still watching weekend wintry potential.

Good Wednesday evening to everyone, we are watching an increasingly active weather pattern heading into this weekend. A couple of storm systems could provide changes for multiple types of precipitation over the next several days…

 

 

The first piece of energy will be dropping southeast from the arctic branch of the jet stream, this energy will help deliver a chilly weekend to region. But ahead of it some moisture will begin to build out ahead of it. You have probably noticed of the 50’s in our county forecasts for tomorrow that is thanks in part to gusty southwest winds.

By Thursday night a frontal boundary will be passing through the Western Carolinas and get east of our area by Friday morning. A line of showers will weaken as it crosses the Appalachians tomorrow night and then pass through during the early morning hours of Friday.

Meanwhile as the colder air filters into the mountains that rain will quickly turn to snow and deliver a solid 1-3+ inch snowfall for the high country. A couple stray flurries could ultimately slide into the foothills after midnight tomorrow night but we do not expect any problems at this time.


 

 

This frontal passage sets up a cold weekend for Western North Carolina with temperatures once again going below average. Temperatures on Friday may struggle to reach the low 40’s with slightly warmer temperatures Saturday as high pressure will be in place.

 

Attention will then shift back in the west as we see a split-flow regime begin. The northers stream energy will be diving down from Western Canada while a separate piece of upper level energy will be quickly moving from the Rockies toward the Southern Plains and Mississippi River Valley.

Precipitation will quickly break out Saturday night along the Mississippi River and into the Mid South moving in our direction. This looks like a bigger system in terms of precip amounts but it will also encounter some of the leftover cold air.

 

Right now we see the chance of some frozen precipitation across the Foothills and Western Piedmont as moisture will move in around daylight Sunday. Precip types could vary from area to area. Right now it looks as if any wintry precip for be fairly short-lived as warmer air aloft takes over and changes everything over to a cold rain by late morning to early afternoon Sunday.

 

Of course that is all subject to change if we see a significant change in guidance but right now we would classify this as a nuisance-type event. We will have an update on everything tomorrow and hopefully our confidence on this will increase some…stay with the Foothills Weather Network for later updates…
