.SHORT TERM...
(Now through Friday)
Issued at 1147 PM CDT Tue Aug 12 2025

The weak easterly wave should continue to move through the region
today and allow for additional convective development during the
late morning through early evening. PWs of 2.21" seem favorable
for coverage and some locally heavier rainfall with convection
that develops. However, decided to shift POPs downward just a bit
given latest guidance/cams being a bit less bullish. This pattern
that has been rather tricky and persistent will finally evolve as
an H5 ridge begins to spread westward from Florida over the
northern Gulf. Eventually, this will help limit POPs slightly and
allow temperatures to increase back into the lower and middle 90s
by the end of the workweek. (Frye)

.LONG TERM...
(Friday night through Tuesday night)
Issued at 1147 PM CDT Tue Aug 12 2025

The weekend begins with a 595dam mid level ridge over the region.
This feature will help overall limit convective coverage during
the afternoon and evening hours, but there continues to be a
signal for isolated to scattered convection even with the high
center over our region. Going through the weekend the ridge will
slowly begin to refocus north and west of our region. Relatively
higher heights will still be around, which suggests temperatures
will be a bit higher...generally at or above average for mid
August. Heat index values look to meet heat advisory criteria this
weekend and potentially into the start of the new workweek. A bit
more moisture may arrive by Tuesday increasing POPs just a bit,
which may help limit heat ever so slightly by the end of the
period. However, heat index values look to remain around 105F or
so on Tuesday. (Frye)

.AVIATION...
(06Z TAFS)
Issued at 1147 PM CDT Tue Aug 12 2025

Eventually, convection will again develop and spread westward
across the region during the late morning and afternoon. Kept
mostly PROBs for now. VIS/CIG reductions can be expected in
convection. Otherwise, winds should continue to remain light and
somewhat variable through the cycle with a bit higher winds
possible around convection. (Frye)

.MARINE...
Issued at 1147 PM CDT Tue Aug 12 2025

Convection will continue with a bit higher coverage today and
perhaps Thursday before high pressure begins to spread into the
region from the east. With convection continue to expect locally
higher winds and seas as well as the potential for more
waterspouts. Otherwise, outside of convection conditions should
remain rather benign, especially later this week and into the
upcoming weekend. (Frye)
