Through next week...

Wet, summer pattern is expected to continue through the period. With
a meaningful change in airmass appearing unlikely, expect daily rain
and storms chances. The upper low currently situated over the
southern plains will shift off to the northeast, maintaining
southerly flow over the area through much of the weekend. As the
upper disturbance shifts east, and high pressure builds from the
west, flow will shift westerly. A nose of drier air pushes in as a
result and shifts the focus of rain and storms further east, with
max PoPs around 80% evident in the I-59 corridor by Sunday. Rain and
storms will likely persist, though gradually decrease in coverage as
flow relaxes with building high pressure. Storms are less likely to
be organized and should be more pulsy in nature next week,
typical of the time of year. Will have to watch for microburst
potential with steeper lapse rates and ample moisture. This will
have to be determined on a day to day basis. Heavy downpours will
also remain possible in the moist airmass, but any more organized
or widespread flash flood potential is too uncertain to determine
right now. Heavier downpours within deeper cores could cause at
least localized flash flooding.

As high pressure builds, the heat builds with it. With temperatures
in the low 90s and dewpoints likely in the upper 70s, heat indices
will be approaching or locally exceeding the 105 threshold for heat
criteria towards the back end of the forecast period later next
week. Recent rainfall and high soil moisture only look to exacerbate
this through evapotranspiration. The high humidity will also lead
to overnight lows only falling to about the mid 70s./SAS/

.AVIATION...
(18Z TAFS)
Issued at 1224 PM CDT Thu Jun 12 2025

A mix of MVFR/VFR flight categories will prevail at area TAF
sites through much of this 18Z forecast period. This is thanks in
large part to varying ceiling heights and isolated to scattered
convection beginning to lift north into the area, as well as
developing across the area. More widespread showers and storms
will be possible later this afternoon as a disturbance moves into
the region from the west. Isolated severe storms will be possible
across areas mainly along and west of a West Point to Pelahatchie
to Brookhaven line. Damaging wind gusts will be the primary
concern with the most intense storms. Winds this afternoon will
have a southerly component and sustained between 5-10 knots. /19/
