Another hot day in the books with no rain…not even a blip on the radar! When little change is expected weather folk like to say “persistence remains the forecast.”Â
Hopefully the ridge of high pressure will break down enough late this weekend and early next week to open the door for some tropical moisture to get into the region. There are two tropical waves in the Caribbean; one in the Eastern Caribbean that remains large but disorganized. The other wave/disturbance is in the Bay of Campeche. You say the Bay of Campeche this time of year and ears perk up! Right now winds aloft would be prohibitive of significant tropical development, but we could see a surge of some of that moisture arriving on our shores by the weekend. Arguments against deep tropical moisture would be vigorous upper westerlies and low level trajectories in the opposite direction. So once again Texas will see the best chance of getting wet with this system as we head into the weekend…hopefully at least the southwestern parts of Acadiana may see better prospects of afternoon storms.Â
Next week holds limited promise of widely scattered afternoon storms, but it won’t even put a ding in the drought. We do need some kind of weak tropical disturbance to help get us out of this situation, but we want to be careful about what we ask for! Â
