New SHORT TERM, LONG TERM, MARINE

SHORT TERM
(Tonight through Tuesday night)
Issued at 226 PM CST Mon Dec 11 2023

The 1024 hPa high pressure centered over the western Gulf Coast this afternoon is forecast to lift northeastward and become centered over the Southeast by Tuesday. The resulting surface pressure gradient will contribute to return flow developing tonight and increasing throughout Tuesday. The increasing low level moisture combined with greater high level cloud cover are expected to limit the efficiency of radiational cooling and result in warmer overnight lows in 40s.
Temperatures will continue to warm on Tuesday despite increasing cloud cover due to moisture return.

LONG TERM
(Wednesday through next Sunday)
Issued at 226 PM CST Mon Dec 11 2023

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

Not much has changed since the last issuance, moisture convergence ahead of a closed mid-level low will allow for increasing chances of showers and potentially some thunderstorms at the latter portions of the work week. The moisture convergence will be influenced by a coastal trough that will develop ahead of the mid level low.
Thunderstorms will likely mainly in the waters though there is a slight chance (about 15-25%) for a thunderstorm to sneak onto land Thursday through Friday along portions of the southern Coastal Bend.
WPC placed the eastern portions of our area in a marginal for Excessive Rainfall with Storm Total QPF showing up to 2 inches possible. Flash flooding isn't expected with this system though it is still possible with rain chances hovering around 60-80% and the potential for training.

High temperatures will drop from the lower 70s Wednesday to the lower 60s to upper 50s by this weekend. Chilly low temperatures will return as well Saturday and linger into next week unfortunately.
One thing that will be continually monitored is the increased risk for coastal flooding along the beaches. A persistent easterly fetch combined with 8-11 second swells that will linger through this weekend could potentially cause wave run up to reach the dunes. Check back for future updates on the need for a Coastal Flood Advisory. Rip current risk will remain high through the weekend due to the agitated seas.

AVIATION
(18Z TAFS)
Issued at 1119 AM CST Mon Dec 11 2023

VFR conditions will prevail through this afternoon and evening with southeast winds less than 10 knots expected. Moisture return early Tuesday morning will contribute to areas of SCT/BKN clouds developing but the likelihood of MVFR ceilings is very low.

MARINE
Issued at 226 PM CST Mon Dec 11 2023

Winds will remain below 15 knots through Tuesday afternoon before a moderate to at times strong easterly flow develops Wednesday and persists through Friday. Winds will shift around to an offshore flow Friday night into Saturday as a cold front advances through the area. Small Craft Advisory conditions will be possible through the week and into the weekend. Isolated to scattered showers Wednesday will become scattered to numerous by the end of the week.
