An area of moisture moving northward into Texas this weekend will bring heavy rain to areas from McAllen to Houston.
As drenching thunderstorms develop in the valley on Saturday afternoon, periods of rain will begin to impact San Antonio and Houston.
The heaviest rain will be confined to the southernmost region of Texas.
“The bulk of the rain will fall on lower Rio Grande Valley during Saturday night,” AccuWeather Expert Senior Meteorologist Dan Kottlowski said.
The recent lack of rainfall has put parts of the valley under severe drought conditions, so rain is likely to be a welcome sight for residents and farmers.
However, the drenching storms will also bring the threat of localized flooding on Saturday night.
“While the rain is needed over the region, enough rain can fall to cause flash and urban flooding in some communities,” Kottlowski said.
“Those living near streams and creeks or in low-lying areas should be prepared to move to higher ground if flooding becomes imminent, and motorists should always take caution not to drive through flooded roadways,” AccuWeather Meteorologist Kyle Elliott said.
The main area of rain will push out of the Rio Grande Valley on Sunday, while it targets areas farther north between San Antonio, Houston and Corpus Christi instead.
“Indications are that rainfall will likely be above average over the region through April,” Kottlowski said.
