.SHORT TERM... (Tonight through Wednesday night) Issued at 148am CST Tuesday Dec 3 2024

Key Message:

-Increasing rain chances today and tonight

No significant changes to the forecast. There's a deep trough over the eastern CONUS, quasi-zonal flow across South Texas and ridging across the Rockies with a developing low just off the coast of Northern, CA. A warm front moving from South to north across our CWA (County Warning Area) tonight will promote a moderate 45-65% chance of rain/showers mainly tonight across the CWA. Another chance for showers tomorrow but activity will move transition further east and will taper off tomorrow/tomorrow night from west to east. There's a moderate to high chance for showers over the Gulf waters.

Afternoon highs today will range from the mid 60s to low 70s today. Tomorrow expect warmer temperatures in the low to mid 70s. Temperatures overnight tonight will range in the 50s with low to mid 60s near and along the coast. These conditions will be accompanied by mostly cloudy skies and generally light northeasterly winds today becoming light and variable tomorrow.

Long Term
(Thursday through next Monday) Issued at 148am CST Tuesday Dec 3 2024

Key Messages:

- Cold front on Thursday brings back cooler temperatures

- Rain chances continue through the week

Warmer temperatures will continue through Thursday before a cold front moves across South Texas. We'll notice slightly cooler low temperatures Thursday night. Temperatures on Friday and Saturday will be in the 60s and low 70s before we start another warm up for Monday. Rain chances will increase once again Thursday with medium (40-60%) chances of rain through Thursday night. Rain chances will diminish from southwest to northeast through Friday night, with low to medium (20-40%) chances of showers persisting through the weekend.

Marine
Issued at 148am CST Tuesday Dec 3 2024

Strong northeasterly flow and elevated seas over the Gulf waters are leading to Small Craft Advisory conditions. These conditions are expected to persist into much of the work week. There's a moderate to high (40-75%) chance of rainfall today and is expected to persist into the middle of the week. Winds will veer onshore tonight becoming moderate onshore flow tomorrow. Then, winds will turn to the northeast Thursday and become moderate to occasionally strong. Onshore flow will return Friday. A high (50-70%) chance of showers will continue over the waters through the weekend, diminishing to a medium (20-50%) early next week.
