Long Term
(Wednesday through next Sunday) Issued at 248pm CST Monday Feb 6 2023

An upper level disturbance/associated cold front are expected to move across the CWA (County Warning Area) Wednesday. Isolated/scattered convection early Wednesday morning, mainly over the Coastal Plains, followed by drier/cooler conditions. Convection may become strong/severe, with SBCAPE as the limiting factor. The foregoing upper system is expected to rapidly lift toward the northeast while another much stronger upper system digs/moves across the Plains/TX Wednesday night through Thursday night. In response to this second system, a polar airmass (the polar jet extends to central TX)/associated secondary surge of high pressure will enter the CWA by Thursday night. Dry and colder conditions are expected over the CWA, with freezing temperatures/hazardous wind chills possible over the Victoria Crossroads/northern Brush Country. Increasing onshore flow/moisture expected Sunday/Monday, as another upper system enters the southwestern CONUS. Anticipate isolated showers over portions of the CWA Monday. Low minimum relative humidity values expected over much of the CWA Thursday through Saturday. However, unclear whether wind speeds will be sufficient for Elevated or Critical fire weather conditions.

Marine
Issued at 248pm CST Monday Feb 6 2023

Southerly winds around 15 to 20 knots will increase to around 20 to 25 knots tonight across portions of the southern bays, nearshore waters and offshore. A Small Craft Advisory will be in effect for these areas beginning at 6pm this evening and continuing through late Tuesday morning. By Tuesday afternoon, winds are expected to decrease to around 10 to 20 knots ahead of an approaching cold front Tuesday night. Isolated to scattered showers will be possible Tuesday, with the activity becoming scattered to numerous Tuesday night. Isolated to scattered thunderstorms will also be possible with the front late Tuesday night.

Scattered showers/thunderstorms expected Wednesday morning, associated with an upper level disturbance/associated cold front. Moderate to strong offshore flow, along with drier and cooler conditions, expected Wednesday afternoon after frontal passage. Moderate to strong offshore flow again Thursday night through Friday night in response to a secondary surge of high pressure associated with a polar airmass.
