Coming out of it
After a freezing start, Wednesday marks the beginning of a moderating trend in temperatures.
Forecast Discussion: A surface high pressure system is sliding eastward into Georgia while a deep upper-level trough of colder air and lower pressures retreats to the northeast. This combination will mean a general warming of the atmosphere with clockwise flowing winds around the surface high returning southeasterly winds to the local area. In addition, with no major features at play besides the high, quiet weather is anticipated through the week. By Saturday, an impressive looking 500mb vorticity maximum and shortwave trough will be swinging through the south. With moisture well established by this time, moderate low-level winds and some shear working through an unseasonably warm and progressive atmosphere-an ideal setup exists for severe weather. In fact, as far as the textbooks go, this setup is much more favorable than last weekend in which one tornado was confirmed. We will closely be watching the Saturday Evening time frame as it nears. Perhaps one missing ingredient would be additional uplift from a front as the next round of chillier temperatures lag behind until Tuesday.
Today and Tonight: Wednesday will begin on a cold note before sunshine enables a 30° improvement into the afternoon. The overnight hours will be far less chilly, returning to the lower 40s under clear skies. A bit of fog may develop in the pre-dawn hours.
Looking ahead: With quiet, mild weather anticipated through Friday, the focus shifts to Saturday Evening for another potential bout of severe weather. At this time, all of the ingredients seem to be in place for at least a few nasty storms. Current timing appears to be late Saturday Afternoon - early Sunday Morning with all threats on the table. We will provide much more information as details become clearer closer to the weekend.
The Tropics: The National Hurricane Center has no areas of interest over the next 48 hours to 5 days.
