Good Sunday evening to everyone, hope you had a Merry Christmas. The holiday weekend is wrapping up. what will the weather look like across the western Carolinas for this final week of 2021?
The first thing we can pretty much guarantee is that this year is going to finish very mild across the southeast US including here in North Carolina. Our region saw record high temperatures for Christmas and that is going to continue at least through the first half of this upcoming week.
The one difference will be at the jetstream level. A stout upper Ridge has dominated the weather pattern here in the southeast over the past few days, however some subtle changes will occur as we go through this week.
Looking at the video above you will notice that westerly winds will gradually veer to the southwest as we head toward mid week. The center of high-pressure that has been over the gulf coast region well shift off the East Coast. Also a stout upper trough will dig into the southwest US to enhance the southwest flow. Some Gulf moisture and even a little Pacific moisture will get entrained into the pattern.
At the surface a frontal boundary will be moving across the Mississippi river valley by Wednesday, moisture will begin to approach the southeast and over spread the region
Shower chances could begin as soon as late Wednesday here across western North Carolina. Those will increase through Wednesday night and will reach its peak during the day on Thursday as the final boundary moves parallel to the Southern Appalachians
The setup that should give the region numerous chances of showers during that time frame mid week. Rainfall amounts right now don’t look overly heavy. We are in a drought and any rainfall is well needed at this time
The first main piece of energy will move through on Thursday, however there could be additional rain chances as we head into next weekend which is New Year’s.
