.SHORT TERM...
(This evening through Thursday Night)
Issued at 1244 PM CST Wed Jan 22 2025

Snowpack continues to melt across SE Texas, though it`s possible
that some of it will survive the sunshine long enough for the
temperature to drop back down tonight. Road conditions have greatly
improved across most of SE Texas, though remember to check TxDOT
(drivetexas.org) before heading out to check for any lingering
impacts that may affect your Thursday morning commute.

A weak, dry cold front is expected to move through SE Texas
overnight into Thursday morning as a mid/upper level trough digs
across the Central Plains/Upper Mississippi River valley. Cloud
cover increases but CAA will be invigorated by the front. Still,
some snowpack may remain in place, which could bring locally cooler
spots where temperatures are a few degrees cooler. Broadly speaking
though, lows for Thursday morning will be in the 20s/30s. Thursday
will be a cool but otherwise benign day as well with northerly flow
still in place. Clearing sky cover and the loss of snowpack should
bring temperatures up by several degrees, with highs reaching the
mid/lower 50s throughout much of SE Texas. Overnight lows into
Friday morning will still be sub-freezing ranging from the 20s to
30s. Remember to bundle up and dress appropriately for the weather.

.LONG TERM...
(Friday through next Tuesday)
Issued at 1244 PM CST Wed Jan 22 2025

High temps on Friday will reach the 50s with light northerly winds
in the wake of the cold front that passes through Wed night/Thu.
Still cold on Saturday morning with min temps in the 30s areawide,
but a significant warmup is on the way on Saturday with high temps
in the mid 60s south and mid 50s north.

Moisture levels return as well on Saturday as SE winds increase.
With the return of Gulf moisture, rain chances will be on the
increase by late Sat and continuing into Sat night. Locally heavy
rainfall will be possible on Sunday near and ahead of another
cold front that pushes offshore overnight. Given the zonal flow
aloft, this front may not make it too far offshore before stalling
and then returning as a warm front on Tue/Tue night. Rain chances
will be back in the forecast on Tue/Tue night as a mid/upper
level low amplifies over the SW U.S., and we see disturbances
move across with the southwest flow aloft.

(18Z TAF Issuance)

.MARINE...
Issued at 1244 PM CST Wed Jan 22 2025

Much quieter conditions over the marine area this afternoon, with
light onshore flow and seas in the 2 to 5 foot range. Another
reinforcing dry cold front will move through late tonight bringing
moderate offshore winds on Thu. Will likely need a caution
statement for Thu and Thu night. Winds will become easterly late
Fri and veer to the SE and increase on Sat. Seas will build on
Sat night and into Sunday. Will likely need an advisory offhsore
at some point this weekend. A cold front will bring showers and
storms Sun night with moderate offshore flow expected in its wake
on Mon.
