.SHORT TERM...
(Tonight through Friday night)
Issued at 1238 PM CDT Wed Oct 1 2025
Today we will remain relatively speaking on the "dry" side in
terms of rain, but we have already started that transition to
steadily increasing moisture. Heights will fall aloft, while at
the surface, an area of high pressure centered west of the Great
Lakes will shift eastward, the Gulf Coast at the base of this will
see easterly flow and small increases in moisture. Tomorrow it
will not be out of the realm of possibility to see isolated to
scattered showers and storms, especially along the coast.

.LONG TERM...
(Saturday through next Tuesday)
Issued at 1238 PM CDT Wed Oct 1 2025
By the weekend elevated PWATs will already be established along
with an upper low taking shape over the central to eastern Gulf
Coast. This will support daily isolated to scattered rain chances
for the duration of the long term, with higher chances along the
coast.
Max temps during that time will be near normal with highs in the
mid to upper 80s. Lows will be slightly above average in the upper
60s to lower 70s.

.MARINE...
Issued at 1238 PM CDT Wed Oct 1 2025
Light to occasionally modest offshore flow and lower seas will
remain through Thursday morning. Hereafter, ridging down from the
Mid-Atlantic area with build toward the Gulf Coast, strengthening an
easterly flow. Shower activity will increase toward the end of the
week with an upper level disturbance developing over the northern
Gulf. Meanwhile winds/seas will build through Friday and remain
elevated through the weekend, before easing and abating early next
week. Small craft should exercise caution during that time, with
a low end probability of a Small Craft Advisory issuance.

.FIRE WEATHER...
Issued at 1238 PM CDT Wed Oct 1 2025
A dry air mass will remain in place with no significant chance for
rainfall through tomorrow morning. Afternoon minimum relative
humidity values are expected to be between 30 and 45 percent today.
Surface winds will remain from mainly the north and northeast at
less than 10 knots. These winds will increase out of the ENE 8-13
knots Thursday and Friday with occasional higher gusts. A
disturbance offshore will help filter more moisture into the area
into the weekend.
