...NEW SHORT TERM, LONG TERM, MARINE...
.SHORT TERM...
(This evening through Saturday night)
Issued at 250 PM CDT Fri Jul 11 2025
A few afternoon storms have developed across parts of the CWFA at
the time of this discussion. As of now, the higher concentration
of convection is across the southshore or along and south of the
I10 corridor. Coverage is mostly widely scattered, less than days
past as an upper level ridge continues to retrograde into the
region. Shower and storm activity should come to an end around or
shortly after sunset. Overnight the main concern will be the
potential for fog over the southwest MS Counties.
Saturday looks to be a skosh warmer than today as the ridge
continues to build further over the region. The ridge will help
limit but not fully stop convection from developing. The best
potential will be west of the Lakes/I55 corridor closer to a
decaying H5 shear axis over northwestern portions of the state.

.LONG TERM...
(Sunday through Thursday night)
Issued at 250 PM CDT Fri Jul 11 2025
Going into the second half of the weekend rain chances are not
zero, but they are not as high as climo POPs, again with the
upper ridge sitting over our region. There may be a weak impulse
at H5 that if timed with the daily sea/lake breeze could ignite a
bit more convection than currently advertised, so that`s something
to watch.
Going into the start of the new workweek, temperatures are going
to go from hot to potentially dangerous with heat index values
approaching headline criteria if not Sunday most certainly Monday
and beyond with some heat index values exceeding 110F on Tuesday.
This would likely be an areawide heat advisory PLUS situation
basically for all of next week. There will be chances of showers
and thunderstorms during the afternoon hours. However, the rain
chances will need to be watched mid to late week next week as an
easterly wave begins to slide under the H5 ridge that by then will
be sitting over the Nashville Basin. The finer details are a bit
fuzzy with most models not really agreeing on placement and
strength. However, the steering currents will weaken a good bit,
which may be the first signal for a potential hydro event setting
up, especially if the GFS and CMC are correct. Nothing set in
stone, but something to monitor as we sweat out the next few days.

.AVIATION...
(18Z TAFS)
Issued at 1129 AM CDT Fri Jul 11 2025
Convection remains possible this afternoon. Covered the potential
for lower VIS/CIGs with PROB/TEMPOs. Outside of convection mostly
VFR conditions with light winds expected through the cycle. MCB
once again may develop some lower VIS conditions overnight. CIGs
will lift after sunrise on Saturday. (Frye)
&&
.MARINE...
Issued at 250 PM CDT Fri Jul 11 2025
High pressure will set up over the local waters through much of
the forecast period. This will keep winds light and variable.
Overall favorable marine conditions expected. That said, there
could still be diurnally driven convection, especially during the
late night and morning hours. In and around convection expect
locally higher winds and seas at least briefly. (Frye)
