.DISCUSSION...
(This afternoon through next Sunday)
Issued at 1132 AM CDT Mon Sep 15 2025
As of 11AM, showers and thunderstorms continue to impact portions
of north Mississippi. This activity will propagate south over the
next few hours before exiting the region. Additional shower and
thunderstorm development is anticipated by late afternoon as an
elevated moisture axis sets up across the Mid-South. The latest
HREF paints a broader coverage area for this activity, so expanded
elevated PoPs east of the MS River. Due to the spotty nature of
this convection, rainfall totals will vary. Regardless, amounts
will do little to combat our drought conditions.
The synoptic pattern will consist of a squashed Omega Block on
Tuesday as an upper level low over the Carolinas retrogrades into
the Mid-South. This, combined with the impingement of a secondary
low over the northern Plains, will result in the gradual breakdown
of the aforementioned Omega Block. As this occurs, daily chances
of rain cannot be ruled out. Greater precipitation chances exist
on Tuesday with Wednesday and Thursday favoring a drier forecast.
Daily highs will remain in the low to mid 90s.
By Friday, a large upper level trough will swing across the
Plains. This system will usher out any remaining ridging, leading
to a return to near-normal temperatures. Highs on Sunday will be
in the upper 80s. In addition to slightly cooler temperatures,
rain chances return Friday afternoon and last into the weekend.

TSRAs and SHRAs will affect both MEM and TUP over the next couple
of hours before dissipating by late morning. At MEM , expect IFR
VSBYs, MVFR/IFR CIGs, and wind gusts up to 30kts in the short
term.
Outside of storms, VFR conditions will prevail at all sites
through mid afternoon. Winds will once again be light and
variable. There is a low-medium chance (20 to 30%) of another
round of scattered -SHRAs and -TSRAs in the late afternoon, mainly
at MEM.

.FIRE WEATHER...
Issued at 1132 AM CDT Mon Sep 15 2025
Elevated fire danger will continue into midweek. Dry fuels and
MinRH around 30 percent will encourage wildland fire development.
However, light 20ft winds will keep fire spread to a minimum.
Spotty showers and thunderstorms are anticipated this afternoon,
but not everyone will see precipitation. Greater wetting rain
chances return on Friday.
