...NEW SHORT TERM, LONG TERM, MARINE...

.SHORT TERM...
(This evening through Thursday night)
Issued at 149 PM CDT Wed Jun 25 2025

Ridging aloft has kept convective coverage minimal today across
the region. This has allowed temperatures to warm into the 90s for
most. There remains a heat advisory through 7PM for the MS Gulf
Coast and locations mostly east of the I55 corridor.

Tonight eyes focus upstream, or since we are still on the
southern periphery of the H5 high centered over the Tennessee
River Valley, this would be east...CAMs are showing signs of
perhaps a complex of convection moving into the MS Counties later
tonight and through the morning hours into southeast Louisiana.
Given the dMIN period, don`t think this will survive too far
inland. However, this could be a source for later redevelopment
with any boundary that lingers across the region. POPs are still
around CLIMO for late June on Thursday. Temperatures again look to
warm well into the 90s. However, with coverage slightly higher
held off on issuing another heat advisory for Thursday, however,
it will be close. An advisory still may be needed and added in
subsequent updates. (Frye)

.LONG TERM...
(Friday through Tuesday night)
Issued at 149 PM CDT Wed Jun 25 2025

Going into the weekend the upper level ridge begins to become more
diffuse as an upper lower moves west from the Atlantic, across
Florida, and into the southeast US. The upper low will help cool
down the upper levels and will help enhance the diurnal cycle
again leading to better coverage of showers and storms across the
area. This upper level feature meanders around the southeast into
the start of the new workweek and eventually moves over our region
toward the end of the period. Again, with the close proximity of
this low, expect a continuation of above CLIMO POPs. Temperatures
through the long range look about average for late June, but may
be held down just a bit with the increase in convection during
peak heating. (Frye)

.AVIATION...
(18Z TAFS)
Issued at 1233 PM CDT Wed Jun 25 2025

Outside of convection, VFR conditions are anticipated through the
cycle. Coverage of convection is very isolated today...so a short
fused TEMPO isn`t impossible, but unlikely at this time for the
local terminals this afternoon. Did add PROBs as there could be a
complex of storms early Thursday morning move east to west from
the MS Gulf Coast into southeast Louisiana. Timing is generally
between 12-18z respectively with the potential for additional
convection in the afternoon. (Frye)

.MARINE...
Issued at 149 PM CDT Wed Jun 25 2025

Outside of convection lighter southeast winds and seas will
continue through the cycle. Convection will be possible overnight
and during the morning hours each day. The better potential will
come later this week and into the weekend as an upper low beings
to settles nearby. Convection will likely cause gusty and variable
winds and locally higher seas. Waterspouts cannot be ruled out in
this environment. (Frye)
