CORPUS CHRISTI, Texas — Isolated severe thunderstorms are expected to develop in the Hill Country and Edwards Plateau this evening and move toward the Coastal Bend late tonight, but a bigger severe weather threat will be on Thursday as a cold front moves into the area.
The primary threats are large hail and damaging straight-line winds.
The main impetus for isolated severe thunderstorms this evening will be buoyant, warm, humid air over the state, with a surface trough moving eastward and undercutting the unstable air.
Tomorrow's risk is enhanced by a southward-moving cold front and added upper-level instability associated with a potent disturbance approaching from the west.
The cold front moves through Thursday night, leaving only isolated showers for your Friday, then retreats north as a warm front early Saturday amid scattered showers and thunderstorms.
Yet another front drives through the area before sunrise on Sunday, with more thunderstorms expected.
Finally, Canadian air sweeps into the region late Sunday night to clear out moisture and bring temperatures much cooler than normal through midweek.
Highs will be in the 70s and 80s, with lows in the 60s, cooling to the lower 50s early next week.
