BRYAN, Texas (KBTX) - It will be a quick, but notable window for severe weather before winter returns and we dry out to finish the week. A strong upper level low pressure system will swing across the Brazos Valley today, giving us a shot at rain and thunderstorms as early as the morning drive, but midday through mid-afternoon brings our best chance for thunderstorms.

STORMS: What to Expect and When

A few showers are possible on the morning drive, then heavier activity is possible closer to midday. From noon to about the afternoon drive, the cold front will move through the area. Ahead of and along the cold front, isolated severe storms will be possible.

  • Northwest Brazos Valley | 11am - 1pm
  • Central Brazos Valley | 1pm - 3pm (including Bryan-College Station)
  • South / Southeast Brazos Valley | 3pm - 6pm

While the overall threat for severe weather is low, it is not totally ruled out -- specifically for storms on or out ahead of the cold front sweeping south. Should a storm need extra attention, gusty wind in excess of 40-60mph would be the main concern. Atmospheric conditions will very briefly support a brief, weak tornado through the afternoon drive, especially southeast. As the front passes, the tornado and severe weather threat ends.

Storms like this should be the exception rather than the rule. For most, a quick downpour and noisy rattles and rumbles of thunder will pass by before a gusty, colder wind takes over.

COLD AIR RETURNS

Temperatures are headed for the mid and upper 60s Wednesday; highs achieved by mid-afternoon for most. As the rain starts to slow and the colder air takes over, temperatures are expected to drop 10° - 15° degrees. That trend takes thermometers sinking to the low and mid-50s by 5-7pm.

Factor in a brisk northwest wind gusting 25-30mph and it will feel another 5° colder than what the thermometer reads. Wind chills in the mid and upper 40s are expected by or shortly after sunset. Wednesday is a good one to take a jacket with you out the door, even if you do not feel like you need it when you leave for the day.
