.DISCUSSION...
Issued at 1216 PM CDT Wed Jul 1 2026
01.12Z upper air maps show an expansive low to mid level ridge of
high pressure centered over the OH/TN River Valleys to the central
Appalachians. The local area remains on the southern periphery of
the ridge and an established easterly flow. Within the flow,
forecasters are monitoring the environment for a marginal risk of
severe storms this afternoon over the northwest zones generally west
of a Luverne AL to Lucedale MS line. A small sliver of a Slight risk
is positioned over Choctaw Co. Afternoon heating has resulted in a
destabilization of the local environment with highest instability
(SBCape's to 4000-5000 J/kg) positioned over the Marginal/Slight
Risk Areas. Pockets of low level lapse rates of ~8C/km, reflecting
regions of deeper mixing and potential of damaging straight line
winds from convective downdrafts, reside more up across central and
northern AL. Our northern flank of counties though are just on the
gradient of the higher low level lapse rates (7.5+ C/km) and will
monitor radar for any over-achieving storms that may become severe
up that way this afternoon. Main threats in any severe storms is
damaging downburst winds in excess of 60 mph.
Widespread heat index values of 102-110 today with the highest
values in the western half of our area. Heat Advisories continue for
our Mississippi counties through 7 PM this evening. For the rest of
the week, the deeply reflected pressure ridge to our north and
larger scale compressional sinking it provides supports minimal
chances of showers/storms. An uptick in summertime shower/storm
chances is suggested by late in the Fourth of July weekend with
chances continuing into early next week as the upper ridge lessens
its grip and the axis of which shifts east of the area. More of a
diurnal summer-time convective mode in the medium range looks to set
up with best chances of showers/storms over land areas during the
day, flipping to Gulf waters at night.
There are indications in the ensembles of some drier air mixing down
to the surface Thursday afternoon which may result in some mid to
upper 60 dewpoints east of I-65 and potentially more focused over
south-central AL to interior NW FL Panhandle. Although a hot day
Thursday with mid 90's for highs, the resultant Heat Index (HI) from
lowering of dewpoints would be held in check at 98-103 east. West of
I-65, HI ranges 101-106. For heat sensitive groups, drink plenty of
water if working/playing outdoors, take frequent breaks and in A/C
when possible, and monitor for signs of heat illness. Overnight lows
muggy, with range of lows generally 73 to 76 interior and upper
70's, perhaps approaching 80 along the coast. /10

.AVIATION...
(18Z TAFS) Issued at 1216 PM CDT Wed Jul 1 2026
VFR conditions expected over the forecast area into the afternoon,
until developing convection drops conditions to mid MVFR levels.
Stronger convection is expected to be along and west of I-65 or
along and south of the coast. VFR conditions are expected to return
in the evening after the convection settles, and last into Thursday
morning. Winds are expected to be light, except near the
thunderstorms. /16

.MARINE...
Issued at 1216 PM CDT Wed Jul 1 2026
A generally light but varying diurnal wind direction expected the
rest of the week with northeast to easterly flow late in the night,
becoming more onshore each afternoon. Light southwesterly flow
becomes prevalent for Sunday and into early next week. Seas 2 feet
or less. /10
