HARLINGEN — The overnight rain and thunderstorms in the Rio Grande Valley were taking a break by late morning, but will return this afternoon and tonight.
The National Weather Service at Brownsville has issued a forecast for scattered thunderstorms redeveloping this afternoon mainly from Hidalgo and Brooks counties toward the coast.
Slow-moving cells or clusters may produce minor flooding in areas with poor drainage, and stronger cells could produce hail and wind gusts to 40 mph or higher with a lot of lightning.
Included in this forecast zone are Cameron, Willacy, Hidalgo, Zapata, Jim Hogg, Brooks, Kenedy and Starr counties.
After another break, isolated thunderstorms are possible near the coast after midnight. Cloud-to-ground lightning will be the biggest threat then, forecasters say.
On Wednesday, isolated to scattered thunderstorms will develop by late morning or early afternoon, mainly east of Highway 281 and favoring locations along I-2 eastward. Primary hazards will be cloud-to-ground lightning and possible minor flooding of poor drainage areas. Hail is also possible in stronger cells.
The potential for severe weather should be gone by Thursday.
