A cold front will sweep through the state on Saturday, bringing rain and colder weather. The heaviest rain will be east of I-35, in south Texas, and along the coast. That makes sense since that is where moisture will be high. Here is how much the computer models are showing thru Sunday.
Over an inch of rain is likely from Brownsville to Corpus to Victoria to Houston to Beaumont. Lesser amounts along I-35 from DFW to Austin to San Antonio.
Unfortunately, it is the western half of the state that is in desperate need of rain and very little is expected in this area. Here is the drought map from Thursday.
Keep doing those rain dances west Texas but the future is not looking good for drought busting rain.
