.SHORT TERM...
(Tonight through Thursday night)
Issued at 226 PM CST Wed Nov 13 2024

A weak cold front will continue to push south and east through the
the Coastal Plains early this afternoon. Slightly drier air and
breezy northwesterly flow can be expected through early evening
before winds subside somewhat overnight. The main difference we`ll
notice will be cooler mornings, both Thursday and Friday, with
temperatures in the 40s and lower 50s. Otherwise, it`ll remain
mostly status quo with high temperatures, but perhaps just 5-10
degrees cooler Thursday. An even bigger cooldown looks to arrive
around this time next week, but for more on that, have a look at the
long term discussion.

.LONG TERM...
(Friday through Wednesday)
Issued at 226 PM CST Wed Nov 13 2024

At the start of the long term period, an upper level ridge will
extend from the Gulf to the upper Mississippi River valley and a
trough will be moving through the west coast states. The flow over
Texas will be from the southwest. High pressure at the surface will
be centered over the central Mississippi valley and the low level
flow will be from the east to southeast across our CWA. This pattern
will shift slowly to the east over the weekend turning the low level
flow to the southeast. Subsident flow will keep the weather dry
Friday and Saturday. Winds from the Gulf will moisten the boundary
layer with dewpoints rising into the 60s by Sunday. A Pacific cold
front will move through west Texas during the day Sunday. There may
be sufficient lift as this front approaches to generate showers
Sunday afternoon, but any activity will be isolated. The upper trough
will lift northeastward from west Texas to Oklahoma Monday and
Tuesday and push the frontal boundary through our CWA. This bring
better chances for rain to South-Central Texas. Rain chances will
move off to the east Monday night. Cooler and drier air will move in
behind the front starting Monday night. The cooler air will be more
evident in the morning with low temperatures around 10 degrees cooler
Tuesday morning with highs Tuesday afternoon within a couple of
degrees of Monday`s highs. Cooler air will continue to filter in
Tuesday and Wednesday morning will be another 5-7 degrees cooler
while afternoon highs will be around ten degrees lower than Tuesday.
