.NEAR TERM...
(Through Tuesday)
Issued at 207 PM EDT Mon Jul 1 2024

A weak cold front is trudging into the Southeast this afternoon and
has been one of the focal points for showers and thunderstorms. One
of the other focal points has been the seabreeze, which got an early
start in Taylor County this morning. All of that will combine to
produce scattered to numerous showers and storms across the region
this afternoon into this evening. Locally heavy rain is the primary
concern, but some gusty winds are possible within the strongest
storms. Additional showers and storms are possible again Tuesday as
the front stalls over the region.

A slight weakness between two H5 ridges is allowing the region to
see a weak cold front enter the Southeast. However, a 594dm H5 ridge
builds in from the west and cause the front to stall over the region
during the near term. Combine this with ample moisture with
precipitable water values (PWATs) between 2.1" to 2.4" and possible
boundary interactions with the seabreeze and outflows means there is
the potential for scattered to numerous showers and storms again
Tuesday. Confidence isn't quite there to extend the Flood Watch into
Tuesday at this time. That said, there remains the chance for some
very heavy rain within any of the stronger storms, which could lead
to localized flooding in urban and poor-drainage areas.

The weak cold front should be just strong enough to knock down
daytime highs a few degrees, especially when you factor in possible
cloud cover and showers/storms around the area, with highs in the
upper 80s to lower 90s. A bit of drier air at the surface should
also bring heat indices down to between 98 to 105 degrees Tuesday
afternoon. Overnight lows tonight will remain quite mild with
temperatures remaining in the middle to upper 70s.

&&

.SHORT TERM...
(Tuesday night through Wednesday night)
Issued at 207 PM EDT Mon Jul 1 2024

The short term will serve as a bit of a transition period between
the wetter pattern we've been in and another ridge settling in
over the area. The stalled front overhead is forecast to wash out
on Wednesday but could still provide a bit of a focusing mechanism
for shower and thunderstorm development Wednesday afternoon. A few
of these storms could produce locally heavy rainfall and could
cause isolated flooding issues if it falls over already saturated
areas. Very humid conditions will continue to persist, as high
temperatures are only forecast in the low to mid 90s but heat
indices will max out in the 105 to 112 degree range. Lows will
remain quite warm in the mid 70s.

&&

.LONG TERM...
(Thursday through Sunday)
Issued at 207 PM EDT Mon Jul 1 2024

Hotter and slightly drier conditions are expected for the long
term as deep layer ridging sets up over the area. This ridge will
help suppress showers and thunderstorms with only an isolated to
scattered chance generally expected in the afternoons. High
temperatures will also soar into the mid to upper 90s or even near
100 once again, with max heat indices in the 106-114 degree range.
If this forecast holds, several days of heat advisories appear
likely. Lows will continue to not be helpful in cooling off, only
dropping into the mid to upper 70s in the overnights.

&&

.AVIATION...
(18Z TAFS)
Issued at 1254 PM EDT Mon Jul 1 2024

Scattered to numerous showers and thunderstorms are anticipated this
afternoon and into the evening hours. MVFR to IFR conditions are
possible within any of the storms that may pass over the aerodromes,
with the best chance for that being KVLD and KTLH with lesser
chances elsewhere. Otherwise, VFR to MVFR conditions are generally
expected to prevail with light to moderate northeasterly to
southeasterly winds.

There is the potential for some lower ceilings and visibility
tonight, but kept it MVFR at this time. Although IFR conditions
are possible with an outside chance at LIFR conditions.

&&

.MARINE...
Issued at 207 PM EDT Mon Jul 1 2024

South to southwest winds are expected through much of the week.
Seas should be around 1 to 2 feet as a result. Scattered showers
and storms are expected through the early portion of the week,
with activity generally greatest in the overnight and early
morning hours as the diurnal land breeze circulation is at its
peak.

&&

.FIRE WEATHER...
Issued at 207 PM EDT Mon Jul 1 2024

Hot and moist conditions are expected through the next several
days with scattered to widespread showers and thunderstorms each
day. Some storms could produce locally heavy rainfall along with
gusty and erratic winds. Otherwise, there are no fire weather
concerns.

&&

.HYDROLOGY...
Issued at 207 PM EDT Mon Jul 1 2024

A flood watch remains in effect for most of the area this evening.
Scattered to widespread showers and thunderstorms are expected
across much of the area today, some of which may produce locally
heavy rainfall. Since storm motions are fairly slow, some flooding
may occur if heavy rainfall rates remain parked over the same
areas for a prolonged period of time. Widespread 1 to 3 inches of
rainfall is expected, with isolated higher amounts possible.

Another round of locally heavy rainfall may be possible on
Tuesday, but confidence is too low to extend the Flood Watch at
this point. If we get a lot of heavy rainfall today and remain
confident in heavy rainfall tomorrow, the watch may be extended
through tomorrow evening.

No river flooding is expected at this time.
