.MESOSCALE UPDATE...
Issued at 807 PM CDT Fri Jun 27 2025

Rest of tonight...

Another quiet night is expected across the Gulf Coast region.
Upper air analysis indicate 500mb ridge centered across the area,
with water vapor imagery indicating 300mb ridge across the
southeast states. Flow will be light and variable overnight.
Convection will continue to wane and should wind down in the next
hour. Light southerly sfc flow and elevated boundary layer
moisture will lead to another seasonably warm night (71-75F).
Updates were sent out earlier. /DC/

.DISCUSSION...
Issued at 1231 PM CDT Fri Jun 27 2025

Rest of Today through next Thursday...Another rinse and repeat
day as a potent upper-lvl ridge continues to provide hot and humid
weather to the region. Heat indices aren`t expected to be greater
than 105 degrees so a heat advisory isn`t needed today. Diurnal
showers/t-storms are expected into the evening hours. Some
organized convection will be possible across southeast/eastern MS.
As a result, a "Marginal" (1 out of 5) risk for severe storms
will be possible across southeast and eastern MS with damaging
winds being the primary hazard of concern.

Over the weekend, the ridge is expected to start flatten over the
southeast CONUS and a longwave trough will settle across the
northern CONUS. Afternoon showers/t-storm chances will continue
through the extended period as a frontal boundary is expected to
stall north of the area and the airmass remains unstable. In
addition to the stalled boundary, northwest flow may usher in some
shortwave disturbances throughout the week. Widespread rain chances
are expected (40-75% PoPs with best PoP chances east of I-55).
Temperatures aren`t expected to be as oppressive as dewpoint ranges
in the lower 70s and highs reaching the lower 90s. Depending on
cloud cover/rainfall received, heat indices could reach 105 degrees
or greater and may warrant a heat advisory but that decision will be
on a day by day bases. /SW/

.AVIATION...
(00Z TAFS)
Issued at 700 PM CDT Fri Jun 27 2025

VFR will be the prevalent flight category, with most convection
winding down and and additional convective development of SHRA
and TSRA between 28/18-23Z Saturday aftn through the end of the
00Z TAF period. Confidence in any fog or stratus is too low to
introduce during the 00Z TAF cycle. Light southerly winds become
variable into Saturday, at times southwesterly, generally under
10mph sustained and gusts. /DC/
