.NEAR TERM...
(Now through Tuesday)
Issued at 430 AM CDT Mon Jul 8 2024

Most areas will likely stay dry today as we continue to sit
underneath subsidence aloft from Hurricane Beryl with at best a
few to scattered showers and storms late afternoon into early
evening. A plume of drier air advected into the forecast area
yesterday into the overnight period, and this should begin to
advect out by this afternoon. PWATs initially start in the 1.5 to
2 inch range, quickly increasing to the 2 to 2.25 inch range this
evening. A large plume of moisture moves into the area for Tuesday
in association with Beryl as it progresses northeast across the
ArkLaTex region. This will bring in PWATs close to 2.25 to 2.75
inches and likewise a substantial increase in rain and
thunderstorm chances.

Given the expectation for decreased convective coverage today it
will once again get hot with highs in the middle 90`s and heat index
values in the 105 to 110 degree range. Given this, have gone ahead
with another heat advisory for the whole area mid morning through
late afternoon for all of the forecast area. Tuesday should be
cooler with highs in the upper 80`s to lower 90`s owing to the
increased convection and cloud cover. At this time it does not
appear that a heat advisory will be needed Tuesday which will be a
nice change of pace with heat index values in the 100 to 105 range.
Overnight lows once again are expected to be in the lower to middle
70`s inland and upper 70`s to lower 80`s nearer the coast.

While the rip current risk remains moderate today, the combination
of another swell packet Tuesday along with increasing onshore winds
should facilitate strong rip currents along Alabama and Florida
Panhandle beaches. Given this, a high risk of rip currents will go
into effect Tuesday morning, lasting into the day Wednesday. MM/25

.LONG TERM...
(Tuesday night through Sunday)
Issued at 430 AM CDT Mon Jul 8 2024

The remnants of Beryl will continue to lift northeastward across
the Mid-Mississippi and Ohio Valley regions Tuesday night into
Wednesday. A weak surface front will move into our forecast area
Wednesday afternoon into Wednesday night before becoming more of
a surface trough axis across our region by Thursday. A plume of
enhanced deep layer moisture with associated precipitable water
values between 1.8 and 2.3 inches is forecast to become oriented
across central and southern portions of our forecast area along
and ahead of the boundary on Wednesday, so we will maintain a
fairly good chance of showers and thunderstorms (40-50%) over the
southern half of the CWA on Wednesday, with lower POPs (20-30%)
across our northern zones. It is possible that POPs will need to
be reduced over the northern part of our forecast area on
Wednesday as a lower PWAT airmass advects in behind the frontal
boundary. Weak ridging aloft is otherwise forecast to build over
the north central Gulf Coast region during the middle to latter
part of the week, before the ridge strengthens somewhat with a
rise in heights Friday into next weekend. Convective coverage may
become more isolated to scattered in nature on Thursday and Friday
and mainly oriented along the surface trough axis/seabreeze near
the coast. We have trended POP values between 20-30% coverage
both days, with the slightly better chance of convection oriented
near the coast. Precipitable water values may trend upward by the
weekend despite the building ridge axis, so scattered convection
looks to be a good bet with good heating and instability this
weekend. Hot and humid conditions will be the rule each day
through the extended forecast with high temperatures ranging in
the lower to mid 90s Wednesday and Thursday and potentially
trending a bit higher in the mid to upper 90s away from the
immediate coast Friday through the weekend. Heat index values look
to stay below advisory criteria for the most part during the
middle to latter part of the week. The latest forecast does have
maximum heat index readings ranging between 102-107 degrees and
locally over 108 degrees over a few spots by next weekend. /21

.MARINE...
Issued at 430 AM CDT Mon Jul 8 2024

Southeasterly flow prevails today before becoming a moderate
southwesterly to westerly flow Tuesday through mid-week. Hurricane
Beryl is moving onshore the Texas coastline this morning and will
continue to provide a long period swell through the rest of today
across our marine waters. MM/25
