A powerful upper disturbance over the Rockies will move out into the plains on Tuesday bringing a variety of weather with it. Snow will be on the back side with severe storms in the warm air sector. SPC places SE LA/MS in the “enhanced” area for strong storms meaning there could be a severe threat mainly after dark into the early hours on Wednesday morning. In addition, a Flash Flood Watch goes into effect for Tuesday PM into early on Wednesday with the potential for 2-4” of rain. Right now it appears whatever squall line forms late Tuesday will be progressive as it moves across south Louisiana. That should limit most rain totals in the lower end of the NWS 2-4” range. Our VIPIR model weakens the line as in nears us after 10 PM thru about 2 AM. Bottom line, we will need to pay attention to this developing situation tomorrow PM and hope that the heaviest storms stay farther to our north. Cooler but not colder air follows this front, but even colder air comes for later in this week. Stay tuned!
