.SHORT TERM...
(Today through Saturday night)
Issued at 238 AM CST Thu Nov 21 2024

Clear, calm and b-e-a-utiful weather is expected over the short
term period! Winds have diminished behind the initial cold front
allowing for overnight temps to fall generally into the low to mid
40s. There`s a few isolated instances of upper 30 temps, but these
should remain isolated.

Upper low pressure spinning over the Ohio River Valley today is
set to spin down a secondary cold front late tonight. This
reinforcing cold air will prolong our seasonally cool temps in
the daytimes, but especially in overnight periods! Latest guidance
has come in stronger with the cold front, trending colder with
overnight temps Friday and Saturday morning. It is still unlikely
to see freezing temperatures in central LA, however, if you`re in
the Alexandria area and would like to see your chances: there is
now a 3 percent chance and 15 percent chance of seeing 32F on
Friday and Saturday mornings, respectively.

Those chances diminish the further south you go: 0 percent Friday
AM, 1 percent Saturday AM for Lake Charles.

Whether thermometers report 32F on these mornings, it`s still
going to feel very cold for those outdoors. Lowest temps are
progged to last a 2 to 4 hour period prior to sunrise so if you
have plants, animals or people vulnerable to temps in the low to
mid 30s, it`s best to plan for keeping them warm now.

As of now, frost is not expected to develop, but if temperatures
do continue to trend lower, the threat of frost development will
increase.

.LONG TERM...
(Sunday through Thursday)
Issued at 238 AM CST Thu Nov 21 2024

Much warmer and breezier conditions to start the longterm period.
Tightening pressure gradient between low in the central US and
high pressure moving to the east will bring about elevated
southerly flow. This flow will then carry with it a moist airmass
off of the Gulf, and thus muggy warmth returns. High temps will
easily lift into the upper 70s to nearly 80 on Sunday with Monday
seeing low 80s area-wide. Both days seeing temps many degrees
above normal for this time of year.

Rain chances return on Tuesday when aforementioned cenUS low
pressure moves east, dragging with it a cool front. This front
does not appear to have very much forcing with it, thus current
rain chances top out less than 20 percent. Another cold front
attempts to move into the region Wednesday or Thursday
(Thanksgiving!!) which looks to bring more widespread showery
rainfall. Stay tuned for updates to your holiday forecast.
