.SHORT TERM...
(Today through Wednesday night)
Issued at 1223 AM CDT Mon Sep 8 2025
Despite a fairly moisture troposphere aloft noted by the 08th/00Z
sounding, surface conditions have trended dry. Areas of high clouds
will slowly erode southward into before dawn, allowing
temperatures sink low to mid 60`s upon sunrise. Pressure
continues to rise as the ridge builds through this afternoon while
temperatures top out several degrees below normal--around the mid
80`s. Naturally, ridging and stable surface conditions will limit
cloud cover to start off the work week mostly clear and dry. This
pattern under clear skies will allow another evening of
widespread lows in the 60`s with a few backyards well inland
potentially touching the upper 50`s by daybreak Tuesday. Winds
will remain out of the northeast, becoming light in the
afternoon. As the center of high pressure pushes off the Canadian
Maritimes, ridging will slack SW to the TX / LA Gulf Coast. High
temperatures will begin a slow climb through Wednesday toward
seasonable norms- into the lower 90`s. Chances of precipitation
remain NIL during this period making it a excellent time to
complete outdoor activities that require an extended period of
rain free conditions.

.LONG TERM...
(Thursday through Monday)
Issued at 1223 AM CDT Mon Sep 8 2025
Trending into the long range Thursday, conditions will warm further
into the lower 90`s as the surface pressure gradient continues slack
and become zonal toward the coast. Thus, winds will acquire more
easterly components while generally remaining light. Meanwhile,
upper level flow begins to modify the ridge pattern east of the
Mississippi and extend into the northern Gulf keeping conditions
relatively dry through the end of the work week. Temperatures
during this range of the forecast likely to top out in the low to
mid 90`s. Northerly flow aloft and broad ridging will help us
hold on to drier weather into this weekend as highs hedge a few
degrees near or above seasonable norms.

.AVIATION...
(12Z TAFS)
Issued at 554 AM CDT Mon Sep 8 2025
A dry, stable airmass will lead to VFR conditions for the TAF
period.
Winds will be from the north-northeast between 10 and 15 knots.
&&
.MARINE...
Issued at 1223 AM CDT Mon Sep 8 2025
A modest offshore flow will remain in place through Wednesday
behind the front that is currently in the coastal waters. Winds
and seas will increase through the morning hours as high pressure
builds down from the Midwest and briefly tightens the pressure
gradient overhead. Small craft should exercise caution through
this period. By the mid week winds/gusts will ease and gain more
easterly components.
&&
.FIRE WEATHER...
Issued at 1223 AM CDT Mon Sep 8 2025
Under dry high pressure regime, afternoon minimum relative
humidity will generally range 30-45% today. Moisture will slowly
return through the mid/late week, mainly along and south of I-10.
Hereafter, dry conditions continue with little to no rainfall
expected through the end of the forecast period.
