FIRST ALERT: Monitoring the tropics for possible development

First Alert Weather 10p 9-12-19

BIRMINGHAM, Ala. (WBRC) - We continue to monitor a tropical disturbance over the Bahamas that is becoming better organized. Forecast guidance suggests this may soon become a Tropical Depression and eventually Tropical Storm Humberto. Tropical Storm Warnings are in effect for the Bahamas and unfortunately this system will impact the same locations impacted by Dorian. A landfall is possible late Saturday in Florida and then the system should weaken and turn to the north-northwest. A front and associated upper level trough is expect to turn the system more northeast with time, which would keep our rain chances limited to scattered storms and showers.

AIR QUALITY ALERT AND NEAR RECORD HEAT: Another code orange air quality alert will be in effect for Friday in Jefferson and Shelby counties. This means ground level ozone concentrations may be hazardous to those with asthma and respiratory illness. The heat will also be at near record levels again, with highs in the upper 90s. Most areas will remain dry, with only isolated showers and storms possible in the afternoon. Temperatures will be tumbling into the upper 80s at game time for high school football with overnight lows in the 70s.

THE WEEKEND: If you have big Saturday plans, rain chances will remain limited, with only isolated afternoon storms. Plan on highs in the 90s, with lots of sunshine. The primary rain chance will be in the afternoon and evening. Any rain or storm delays would be temporary and similar weather can be expected for Sunday, with a slightly better coverage of afternoon storms. If the tropical system tracks a bit further west that could increase our Sunday and Monday rain chance. Right now it looks like the coverage of rain will remain very scattered through most of next week. The good news is we have a small rain chance in the forecast and daytime temperatures look to be backing off slightly with highs in the low 90s next week.

COLLEGE FOOTBALL: Plan for very hot and steamy weather in Columbia, South Carolina for the Alabama game. The tropical system won’t impact Columbia on Saturday, although isolated storms will be in the forecast. I’d also plan for some hot and steamy weather for the tailgate at Auburn and be on the lookout for scattered pop-up storms. The good news is game time will be later, so we will have some relief in the heat levels by half time at Jordan-Hare.
