Rain Returns After Brief Cold Snap; Another Cold Weekend Expected

Rain will be returning to the Carolinas on Wednesday and Thursday as another storm system moves across the United States this week.

500 MB Map on Tuesday Evening shows our next storm system stretching across the United States.

An Arctic high pressure has settled into the Carolinas Sunday evening, and this will lead to below average temperatures Monday and Tuesday. This area of high pressure; however, will move quickly to our east as another system moves into the center of the country Tuesday.

This system will once again allow warm air from the Gulf of Mexico to move northward into the Carolinas, which results in temperatures being too warm for wintry weather. A little bit of sleet or freezing rain is possible on Wednesday morning in the mountains and foothills; however, this would change quickly to a cold rain.

The GFS computer model shows the progression of this system from Wednesday morning through Thursday evening. The heaviest rain is expected to enter the mountains Wednesday evening and move eastward into the Charlotte metro by Thursday morning before pulling to the east by Thursday evening.

With another front pulling copious amounts of moisture northward from the Gulf of Mexico, I am expecting another 1-2 inches of rain from this system. The WPC shows most of the Carolinas receiving at least an inch of rain, with the highest amounts in the mountains and foothills.

After this front, a quick moving Alberta Clipper may bring a few snow showers to the mountains Friday. For the rest of us, we will see windy conditions behind the cold front that will usher in another cold blast of Arctic air for the weekend. Temperatures next weekend are expected to be 10-20 degrees below average for this time of year.

The GFS computer model shows the much below average temperatures coming from the midwest southward into the southeast United States for Friday, Saturday, and Sunday. In the long range, it looks like below average temperatures are likely to continue into the last week of January.
