SHORT TERM
(Today through Tuesday)
Issued at 433 AM CST Mon Dec 11 2023

Mesonet sites across the northern Coastal Bend into the Victoria Crossroads show temperatures below freezing in low lying areas where drainage effects have occurred. The Freeze Warning will continue for this area along with Live Oak and McMullen Counties until 8 AM.

After a cold start, temperatures will rebound into the upper 60s to near 70 for inland areas as a weak onshore flow develops this afternoon with the surface high pressure ridge moving to the east.
Generally sunny skies are expected with some thin cirrus possible across southern part of the forecast area.

An upper trough moving through the Intermountain West today will drop south into the Great Basin and form into a closed low Tuesday afternoon. With surface trough of low pressure forming over the southern Rockies, low level flow will develop tonight and increase on Tuesday. NAM appears too aggressive with moisture return tonight, prefer the GFS showing moisture in the 295-300K layer increasing during the day Tuesday. Even with increasing clouds, temperatures are expected to warm into the 70s Tuesday.

LONG TERM
(Tuesday night through next Sunday)
Issued at 433 AM CST Mon Dec 11 2023

Key Messages:

- Increased rain chances mid to late week

- Marginal risk for excessive rainfall Friday into Friday night

- Potential for minor coastal flooding and an increased risk of rip currents late week

A coastal trough developing ahead of the next advancing upper level system and associated cold front will lead to a steady increase in moisture across the area mid to late week. PWATs are progged to increase to near 1.3-1.5 inches by Wednesday, peaking at around 1.6 inches by Friday ahead of the front. Isolated to scattered showers Wednesday (20-30%) will become scattered to numerous by Friday (50- 70%), with a few embedded thunderstorms possible. Although widespread flash flooding is not anticipated at this time, WPC has highlighted eastern portions of our CWA under a Marginal risk for excessive rainfall on Friday, with total rainfall amounts adding up to 2 inches through the end of the period.

The upper level low is progged to swing into west Texas Thursday night into early Friday morning, and exit somewhere along the upper Texas coast or Southeast Texas Saturday night, with high pressure quickly building in behind it. The front itself is expected to reach South Texas Friday evening leading to breezy, cooler and drier conditions on its wake. Rain chances will diminish Saturday through Sunday, though lingering moisture will maintain slight rain chances across the marine zones. High temperatures will range in the 60s and 70s ahead of the front, and in the 50s and 60s behind it. Saturday night is shaping to be the coldest in the Extended range with overnight lows dipping into the low to mid 40s inland.

In terms of additional hazards, there will be an increased risk for rip currents and minor coastal flooding along the Gulf-facing beaches of the Middle Texas Coast as we head into the latter part of the week. A persistent moderate to at times strong easterly flow offshore and swell periods around 8-11 seconds may bring run-up above 2 feet MSL mainly at the time of high tide beginning Thursday night. Although no advisories are in effect for this event yet, we will need to continue to monitor the beach and seas conditions in case one is needed on a later package.
