CORPUS CHRISTI, Texas — Fair skies and light wind prevails tonight and Sunday, then Gulf moisture returns ahead of a storm that promises significant rainfall Tuesday through Thursday.
Expect a southeast wind of 15 to 25 mph Monday and Tuesday, pushing highs into the 70s and lows from the upper 50s to lower 60s. A weak trough will shift wind to the north briefly overnight tonight and into Sunday, but the high pressure behind the trough quickly moves east and returns southeasterly flow by Sunday night.
That onshore flow dramatically increases by Tuesday as a storm system in the Desert Southwest intensifies. It is that system that will pull Gulf moisture into our region and lift it to generate scattered showers beginning late Tuesday.
Showers become numerous Tuesday night through Wednesday, then taper off Wednesday night and Thursday. No cold air will be associated with the wet weather scenario, but rainfall totals should accumulate to between 1/2 and 1 1/2 inches.
