.NEAR TERM... (Tonight) Issued at 321 PM CDT Wed Sep 10 2025
Dry conditions continue across the Tennessee Valley as an upper level ridge continues to nudge its way eastward and subsequent sfc high pressure resides over our area. Low temperatures overnight are forecast to drop into the low to mid 60s under mostly clear skies. Lack of sufficient moisture should deter fog formation overnight.

.SHORT TERM... (Thursday through Saturday) Issued at 1108 AM CDT Wed Sep 10 2025
High pressure will remain the dominant weather feature across the region late this week, gradually building into the lower Mississippi Valley and Mid South from the Southern Plains. Mostly sunny and dry conditions will continue each day, with heat beginning to build, especially by the weekend. Ample sunshine will allow highs to reach the low to potentially mid 90s, especially by Friday and Saturday. The drier air mass will help keep dewpoints and RH values in check, with heat index values remaining below 100 degrees.

.LONG TERM... (Saturday through Tuesday) Issued at 1047 PM CDT Tue Sep 9 2025
The upper ridge/high will continue to be the dominating factor on weather here locally with a much warmer airmass persisting into next week. With large scale subsidence in place, we will maintain a dry forecast through the extended period and the main impact will transition more to the dry heat. Thankfully, the better moisture will be suppressed to our south which will help limit heat indices below the 100 degree mark. Overnight lows will be on the warmer side too, dropping to the mid to upper 60s but thankfully not as bad as the hot, muggy nights we saw nearly a month ago. So hang in there, summer is not over yet! Remember to practice heat safety as we head through the remainder of the week and weekend and never leave people or pets unattended in vehicles!
