Moisture is increasing, leading to a better opportunity for rain ans storms... Hot and steamy this afternoon with highs in the middle 90s and heat indices over 100. Pop-up showers and storms develop during the heat of the day; the chance for rain at any given location is low, but don't be surprised if you cant a brief downpour.
We're watching the tropics where remnants of Harvey are showing signs of life near the Yucatan Peninsula. Conditions are somewhat favorable for redevelopment over the next 24-48 hours; if that happens, a depression or tropical storm could form within that time. Models are in good agreement that it will track toward the Mexican or Texas coast by Friday. If this does pan out, it would mean greater rain chances for Mississippi over the weekend. Another forecast factor is a weak cold front that will slip into the state Wednesday into Thursday, delivering slightly cooler and drier air, that would limit rain chances north of the front from any tropical system that does develop. Bottom line, still more questions than answers; please check back for updates as we iron out the details.
