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 this morning. Low temperatures in the advisory locations were in the lower to mid-30s and frost formed before the sun came up.
TODAY: High pressure will start the day 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 will be in the mid to upper 70s.
MONDAY: The high moves further from the state to start the work week and the cold front continues to stay off to our north and northwest. While this may bring a few scattered clouds to Alabama, skies will remain mostly clear with no rain. Highs will be warmer again, reaching the upper 70s to the lower 80s.
TUESDAY: 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, 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; afternoon highs will reach the lower to mid-80s.
THURSDAY: The remnants of the washed-out front continue 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 Alabama for the end of the work week and into the start of next weekend, increasing our shower and thunderstorm chances for the afternoon. Otherwise, skies will be partly cloudy and temperatures will step back into the mid-70s to the lower 80s.
THE TROPICS: The Global Forecast System 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 about 500 miles east-southeast of Bermuda. Although the circulation is still somewhat elongated, the center appears better defined than it was Friday. 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 southeast of Bermuda.
Formation chance is 70% in the next two days and 80% in the next five days.
We also have a broad area of low pressure 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 is near zero within two days and 30% within five days.
