A Flash Flood Watch has been issued for the majority of the viewing area until 1 a.m. Friday as periods of heavy rain is expected to last throughout Thursday. Some could see around 3+" of new rain over the next 36 hours.

One last round of strong to severe storms will race in Thursday afternoon into the night alongside the excessive rainfall threat. By Friday, a dramatic shift in the weather pattern heads our way. Fall makes a brief comeback as temperatures look to top off in the upper 60s alongside strong winds from the west.

This will be due to a passing cold front that will also be responsible for pushing away leftover rain and storms from the workweek. Our next chance for showers and storms heads in Saturday night/Sunday morning, but the weekend also brings a very impressive rebound as temps climb back into the 80s under mostly sunny skies for the rest of Sunday.

The next work week looks to stay above average with temperatures maxing out in the low to mid-80s.
