.DISCUSSION...
Issued at 1111 AM CST Mon Dec 8 2025

Mainly quiet weather, plentiful sunshine and a very low (less than
10%) chance of rain is expected to continue for Deep South Texas
through Thursday as ridging aloft persists. In wake of last night`s
cold front, northerly winds from a surface high pressure over the
Southern Plains gradually become easterly tomorrow and southerly by
Wednesday morning as the high slides eastward across the Deep South
US. Moisture begins to build on Friday from southeasterly winds
around a high over the Gulf as a cold front pushes through much of
Texas. Although uncertainty still remains if the front will make
it to our region Friday night, probabilities of precipitation
(PoP`s) are currently anticipated to rise from a low (15-20%)
chance near the coast Friday night to a low to medium (20-40%) by
Saturday morning, highest near the coast. PoP`s decrease inland
throughout Saturday, though coastal troughing may keep a low
(15-20%) chance of rain near the Lower Texas coast into Monday.

Temperatures today and tonight are likely to be the coolest of the
forecast period as highs remain in the mid to upper 60s to possibly
near 70 degrees F for portions of the Rio Grande Valley,
particularly further west. Lows tonight drop to the low to mid
40s inland, near 50 degrees F in Brownsville and low 60s near the
coast. As winds veer to southeasterly to southerly by midweek,
highs rise from the 70s tomorrow to mostly 80s from Wednesday
onward, potentially peaking on Thursday. Overnight minimum
temperatures rise from the 50s tomorrow night to mainly 60s by
Wednesday night.

A high risk of rip currents continues through this afternoon,
becoming a moderate risk overnight tonight and a low risk by
tomorrow morning.
