(Today)
Issued at 230 AM CDT Sat Jul 19 2025

Throughout the day today high pressure will continue to
retrograde across the FL Peninsula. The resulting SE flow will
maintain our tropical airmass with PWATS in the 2-2.25 inch range.
The moist environment will support the development of showers and
thunderstorms along any boundaries that develop throughout the
day. Currently, a few scattered storms along with a low cloud deck
are pushing north along a lingering outflow boundary into Cullman
County. This activity is expected continue through the remainder
of the night and into the morning slowly spreading north. With day
break, diurnal heating will aid in increasing coverage of showers
and storms through the afternoon. With such a saturated airmass,
any storms that do develop will be capable of very efficient
rainfall production. Thus, we will have to keep an eye out for
storms that train or stall over the same area for flooding
concerns.

The cloudy skies and rain chances will limit afternoon
temperatures to the mid to high 80s. While it will undoubtedly be
incredibly humid outside with dew points forecast in the high
70s, temperatures look to increase significantly as we head into
the next work week so enjoy the slightly cooler temps while they
last.

.SHORT TERM...
(Sunday through Tuesday)
Issued at 743 PM CDT Fri Jul 18 2025

The reservoir of high PWs will remain in place through Sunday.
MCSs dropping southeast from the Great Lakes and Corn Belt will
enter eastern KY and TN during the afternoon. We will have to
monitor any strong outflows surging southwest from these clusters,
but at this time, it appears they will remain to our northeast.
On Monday as the mid and upper level ridge amplifies along and
west of the MS River, there could be a tendency for the MCS
activity to move more due to south which could clip our eastern
counties. Thus, higher NBM PoPs are indicated the next few days in
our eastern counties. With the building ridge, temperatures will
warm into the lower 90s Sunday and Monday afternoon with the
exception being upper 80s to around 90 in our eastern counties and
higher plateau areas.

.LONG TERM...
(Tuesday night through Saturday)
Issued at 743 PM CDT Fri Jul 18 2025

Mid and upper level heights will increase with the 5h anticyclone
building over the mid South Wednesday into Friday. This will
stunt thunderstorm activity further mainly to our south along the
Gulf Coast associated with another westward moving wave. However,
ridge rider MCSs/MCVs are indicated in the models that may rotate
southwest through the Piedmont and lower Appalachians which could
enter eastern AL at times next week. Thus, low chances will exist
each day, mainly in our eastern forecast area. Typical summertime
heat is expected as well which will become persistent with time.
High temperatures will consistently reach the lower to middle 90s,
with lows in the lower 70s east to middle 70s west. Heat index
values will likely reach or possibly exceed 105F in our central
and western counties, and in the upper 90s to lower 100s in our
eastern counties. Heat Risk levels of 2-3 are indicated all week
as well.

(12Z TAFS)
Issued at 540 AM CDT Sat Jul 19 2025

Scattered thunderstorms with MVFR ceilings are currently moving
through HSV. Low ceiling and VCTS are expected to remain through
midday, at which point ceilings look to improve to VFR yet
coverageof showers and storms will likely increase. Any storm
that moves directly over the terminals will be capable of briefly
lowering both ceilings and visibilities. Storms will wane after
sunset with VFR conditions prevailing for the remainder of the TAF
period.
