Monsoon isn't done yet folks. After a relatively calm, warm, and breezy weekend, thunderstorms move back into our weather forecast. The current weather set up shows high pressure off to our east/southeast. With clockwise flow around that system, moisture will be picked up from the Gulf of Mexico and streamed up the Rio Grande Valley into our region over the coming days. Already clouds are moving our way from South Texas, where storms brought up to half a foot of rain from Brownsville back to Corpus Christi this weekend.

Monday Set Up:


Initially storms will be spotty at best for Monday and Tuesday. By Wednesday, with plenty of deep moisture in place and an upper level storm (we call it a trough) moving in from the west, thunderstorms will erupt in a big way. We're looking at the threat for stronger storms... which means heavy rains.... along with the threat for large hail and damaging winds. The best chances of near severe storms will be Wednesday with just a threat for isolated heavy rain into Thursday. Friday looks a little more quiet before a surface cool front tries to reactivate the moisture and bring more thunderstorms for Saturday. Naturally there will be changes to this forecast, so keep with Newschannel 9 and for the latest.
