Sea Breeze Showers, Then Numerous Showers

By  | 

Desert air has drifted to our north. A sufficient amount of gulf moisture has replaced the dry air, fueling scattered showers with, and in advance of the arrival of the sea breeze each late afternoon. A disturbance will move into Belize and across the Yucatan Thursday and Friday. Once it moves into the gulf, it will have a low chance of developing into a tropical cyclone. The National Hurricane Center gives it a 20% chance of doing so. Strong west to northwest winds aloft may prevent the system from organizing. Either way, the deeper layer of tropical moisture will track northwestward into south Texas, bringing more numerous showers, some perhaps heavy, Sunday through Wednesday.

I'm expecting showers to fade away after sunset, partly cloudy and humid tonight, low in the high 70's. Partly cloudy with isolated to scattered showers with, and in advance of the sea breeze each afternoon Thursday through Saturday, highs in the high 90's. Mostly cloudy with more widespread showers and thundershowers Sunday through Wednesday, some showers may be heavy, high in the low to mid 90's.
