A weak upper level disturbance will move out of Mexico today and move northeast across central Texas today. It will pass just close enough to our northwest to give southeast Texas a 30% chance for late morning and afternoon thunderstorms. I think our north and west counties have the best chance for seeing the rain. Columbus, Sealy, Katy, Hempestead, Brenham, Conroe, Huntsville... you guys have the best chance for afternoon storms. Here's a look at the computer model for early afternoon.
