TRACKING SHOWERS AND STORMS: A cold front will be pushing across our area over the next 12 hours and this will bring a chance of scattered showers and storms that will continue into the early evening. At the time of this update, scattered storms were impacting areas stretching from Pickens County northeast to Cherokee County. Some storms may be strong with 20-30 mph wind gusts and frequent lightning. The front will settle over southern areas tomorrow, with a continuing chance for scattered showers and storms, mainly south of I-20. Temperatures will be noticeably lower for tomorrow, with some areas to the far north struggling to reach highs near 80°.
ANOTHER SURGE OF MUCH COOLER AIR FOR MID-WEEK: We will see a stronger surge of cool/dry air on Wednesday as an upper air trough develops over the Eastern United States. Temperatures for mid to late week will top out in the 70s, with overnight lows in the low 50s by early Thursday and Friday. I mentioned yesterday that you may want to dig in the closet and pull out a long sleeve pullover for the morning hours later this week. It’s going to be very chilly at the bus stop, especially over northern areas by Thursday morning. A few areas over the Tennessee Valley could see upper 40s early Thursday. Some model data suggest we could see a slight increase in cloud cover Thursday as the upper air trough digs southward. This could spark a stray shower over far northern areas so we’ve included a small 20% chance of a shower. It is going to be breezy at times later this week, with a cool north wind.
DROUGHT UPDATE: Unfortunately drought conditions will continue. In fact, parts of the area, east of I-65, are dealing with severe drought conditions. I would be extra careful with respect to fires and avoid burning as low relative humidity and breezy conditions will lead to dangerous fire weather conditions over the coming days. Other than the small rain chance for the end of the work-week, long range data suggests another cold front will impact the state around the October 6th timeframe and this will likely bring our next chance of beneficial rain.
TROPICAL UPDATE: The big story in the tropics will be a strong disturbance labeled as INVEST_97L. There is a good chance this will develop into a tropical depression and track west towards the Caribbean. Once this system becomes better organized we will have frequent forecast track updates posted on the First Alert Weather App. We will have updates on the tropics and cooler weather beginning with the four on WBRC.
