.DISCUSSION...
(This afternoon through next Monday)
Issued at 1149 AM CDT Tue Sep 16 2025
The latest HREF guidance indicates potential for isolated shower
and thunderstorm development this afternoon, mainly along the TN
River south towards the MS/AL state line. Any storm that does form
will exist in an environment not conducive for upscale growth.
Therefore, severe weather chances are limited. Instead, expect a
few spotty downpours.
An upper level blocking pattern will continue to breakdown through
Thursday as a low pressure system over the Carolinas retrogrades
towards the Mid-South. By Friday, a secondary low located over the
northern Plains will eject a shortwave towards Missouri. This
system will bring increased rain chances to the Mid-South, though
widespread rainfall is not anticipated. Elevated precipitation
chances will exist through Saturday with storm total amounts
topping out at half an inch.
The extended forecast calls for a large "bowling ball" trough
developing over central CONUS by next Tuesday. Both the GFS and
ECMWF vary in exact placement of this system, meaning next week`s
weather remains hard to pinpoint. Stay tuned.

(00Z TAFS)
Issued at 611 PM CDT Tue Sep 16 2025
With the ridge essentially directly overhead, surface winds will
be light and variable throughout the period. Peak heating may
give way to very sporadic convection tomorrow, though coverage
looks even more sparse than it was today. As such, no mention was
made in the TAFs. VFR conditions continue to prevail.

.FIRE WEATHER...
Issued at 1149 AM CDT Tue Sep 16 2025
MinRH will fall in the 30 to 40 percent range through tomorrow.
Spotty thunderstorms remain possible this afternoon, though
widespread precipitation is not anticipated. Expect wetting rain
chances to return by the end of the week.
