.SHORT TERM... (Tonight through Monday Night) Issued at 1026 PM CDT Sat Oct 4 2025
High pressure continues its influence on the area into Sunday, resulting in another nice day to end the weekend. No hazardous weather is expected with dry conditions continuing and mostly sunny skies contributing to above normal temperatures as highs warm into the mid and upper-80s.
But by Sunday night, the center of the upper-level high moves off to the east which in turns allows for southerly flow to set up over the southeast US. This southerly flow brings Gulf moisture up into the area which will start to increase our rain chances as we start the new work week. Low rain chances start to build primarily west of I-65 Sunday night, but rain chances increase to around 30-40% during the day on Monday across the same area with lower chances towards the east. This surge of Gulf moisture will allow PWATs to increase to around 1.6-1.75 inches which is above the 90th percentile for this time of the year. Despite this abundant moisture source, there is still a lack of strong overall forcing. And as CAMs start to come into view for this time frame, they suggest activity will be widely scattered with probabilities of receiving more than 0.25" low. With that said, there may still be isolated areas that pick up more than a half inch of rain thanks to abundant moisture and instability, but this probability is around 20% for the western counties.

.LONG TERM... (Tuesday through next Sunday) Issued at 1026 PM CDT Sat Oct 4 2025
Moisture advection continues into Tuesday with PWATs ranging from 1.7 to 1.8 inches - still above the 90th percentile. Forcing increases though on Tuesday and Wednesday as a shortwave and associated front track through the area. This will allow precipitation chances to increase to 60-80% Tuesday and Tuesday night before the front clears the area on Wednesday. With this added forcing, this time frame will be our best chance for higher rain amounts. By Wednesday night, the chance for rain totals exceeding one inch generally range from 40-60% with the higher chances across the western half of Middle TN.
Drier conditions with just low rain chances return to the area starting on Thursday. Even better news though is that temperatures will cool down post-front. High temperatures Thursday and into the weekend look to generally be in the 70s.

.AVIATION... (00Z TAFS) Issued at 633 PM CDT Sat Oct 4 2025
A pesky surface ridge remains the dominant weather feature affecting Middle Tennessee this evening, so the TAFs are once again VFR (with the possible exception of overnight radiation fog at KSRB). Tomorrow, expect surface winds to increase from the SE as the pressure gradient starts to right up.
