There will be several rounds of precipitation that will bring heavy rain and possibly some severe storms tonight through early Thursday morning.
A slow moving cold front will serve as a focus for showers and thunderstorms tonight, mainly northwest of a Brenham to Livingston line. Training of storms is likely and some heavy rainfall totals are possible. Rainfall totals north the aforementioned line will average between 2 and 3 inches by Wednesday morning with some isolated totals between 4 and 6 inches possible.
The front will move slowly across the area on Wednesday and showers and thunderstorms will develop. Locally heavy rain will again be likely along with the potential for severe storms in the afternoon/early evening.
Storms will be ongoing at sunrise over the north and these should end by mid morning.
Additional storms will begin to redevelop around 1 PM and expand in coverage and intensity during the afternoon. There should be a brief gap in the storms before yet another round of precipitation develops mid evening and lingers through early Thursday morning.
