FROST ADVISORY: All counties in North Alabama and several counties in the extreme northern parts of Central Alabama are under a Frost Advisory until 8:00 this morning. Low temperatures in the advisory locations will be in the lower to mid-30s and frost will form before the sun comes up.
SATURDAY: High pressure will start the day on Saturday off to our northeast which will keep our weather sunny, dry, and mild. After the chilly start and the Frost Advisories expire, it will warm up nicely into the lower 70s across Central Alabama.
SUNDAY: We’ll be sandwiched in between the high off to our northeast and an approaching cold front that will temporarily stall out to our northwest. This will allow slightly warmer temperatures to end the weekend as highs across Central Alabama will be in the mid to upper 70s.
MONDAY: The high moves further away from the area to start the workweek and the cold front continues to stay off to our north and northwest. While this may bring a few scattered clouds to the area, skies will remain mostly clear with no rain. Highs will be warmer again, reaching the upper 70s to the lower 80s.
TUESDAY: Not much change for your Tuesday as the front continues to hang out just off to our north and northwest. While a few more clouds are possible, temperatures will stay in the same neighborhood reaching the upper 70s to the lower 80s.
WEDNESDAY: The combination of the stalled front’s location and advection of warm and moist air from the south will bring a chance of an isolated afternoon shower into the forecast for Wednesday. We’ll have a mix of sun and clouds, otherwise, with afternoon highs reaching the lower to mid-80s across Central Alabama.
THURSDAY: Same story as Wednesday, the remnants of the washed-out front continues to linger around just to our north and northwest, and with the increased warmth and moisture from the south, a few isolated showers will be possible during the afternoon. Highs will be in the lower to mid-80s.
FRIDAY: A deepening trough off to our west and northwest will finally push the boundary into and out of the area for the end of the workweek and into the start of next weekend that will bring an increase to our shower and thunderstorm chances for the afternoon hours. Otherwise, skies will be partly cloudy, and temperatures will step back into the mid-70s to the lower 80s.
THE TROPICS: I’m sure that you have noticed on the last couple of forecast images from the GFS that it is painting a tropical system moving up from the Caribbean Sea and eventually running just offshore of the east coast. At this point, it is not a given that this situation will occur as this steps off into Voodoo Land. Here is what we do know from the National Hurricane Center:
We have showers and thunderstorms that continue to gradually become better
organized in association with a non-tropical low-pressure system located about 500 miles east-southeast of Bermuda. Although the circulation is still somewhat elongated, the center appears better defined than it was yesterday. Continued slow development is expected, and a subtropical depression or storm is likely to form during the next couple of days while the low meanders well to the southeast of Bermuda.
* Formation chance through 48 hours…high…70 percent.
* Formation chance through 5 days…high…80 percent.
We also have a broad area of low pressure is expected to form in a few days over the southwestern Caribbean Sea. Some gradual development of this system will be possible through the middle of next week while it moves slowly over the southwestern or western Caribbean Sea.
* Formation chance through 48 hours…low…near 0 percent.
* Formation chance through 5 days…low…30 percent.
