...New AVIATION...
.KEY MESSAGES...
- High pressure at the surface and aloft will keep a dry air mass
  in place through midweek with no chance for rain, very warm
  days, and mild nights.
- An increase in moisture to go along with a developing upper
  level disturbance will bring a small chance for rain late in the
  week into this weekend.

.SHORT TERM...
(Tonight through Wednesday night)
Issued at 1225 PM CDT Mon Sep 29 2025
We`ll see dry and warm weather through Wednesday thanks to high
pressure systems both at the surface and aloft. Both max and min
temperatures will be generally 5 degrees above normal. The surface
high pressure is located over the Great Lakes region, with riding
extending across parts of the SE CONUS then across the Gulf Coast
States. This will drift off from the area, however its influence
will be present through the short term. There are 2 high pressures
aloft, one over the plains and another over coastal TX/MX. We will
see heights rise with the latter one, with NW flow aloft.
&&
.LONG TERM...
(Thursday through next Sunday)
Issued at 1225 PM CDT Mon Sep 29 2025
A pattern shift will take place at the beginning of the long term.
The surface high pressure will move over the NE Atlantic Coast,
allowing an easterly to southeasterly flow to bring increased
moisture from the Gulf. This, combined with a weakness forming
over the Gulf, will introduce isolated to scattered showers back
into the forecast from Thursday to the end of the long term
period. Even with that said, chances will be higher the further
south in the CWA you go, and maxed out at about 30 to 40 percent.
The moisture and cloud cover will bring max temps down a few
degrees, however we can expect more humid conditions.

.AVIATION...
(00Z TAFS)
Issued at 624 PM CDT Mon Sep 29 2025
VFR conditions expected to remain through the TAF period while
upper level clouds increase slightly through the overnight hours.
Winds out of the north to become light and variable through dawn.
&&
.MARINE...
Issued at 1225 PM CDT Mon Sep 29 2025
Surface high pressure ridging down into the coastal waters through
mid week will keep a light to occasionally modest offshore flow to
go along with mainly low seas. By the end of the week, the surface
high will be ridging down from the Mid-Atlantic area, producing
more of an easterly flow. No significant chance of shower activity
is noted through mid week, with shower activity increasing toward
the end of the week with an upper level disturbance developing
over the northern Gulf.
&&
.FIRE WEATHER...
Issued at 1225 PM CDT Mon Sep 29 2025
The forecast pattern will not change much over the next few days
with high pressure at the surface and aloft over the region.
Therefore, a dry air mass will remain in place with no significant
chance for rainfall through midweek. Afternoon minimum relative
humidity values are expected to be between 35 and 45 percent today
through Wednesday. Surface winds will remain from mainly the north
and northeast at less than 10 knots.
