KEY MESSAGES

- Cooler, drier weather early this week will transition to warmer and more humid by mid to late week.

- Chances for showers and thunderstorms will return to portions of the forecast area by mid week.

DISCUSSION

Issued at 128 PM CDT Sun Apr 5 2026

In the wake of last night's cold front passage, cold and dry advection is keeping temperatures mostly below 70 degrees across the forecast area today. Earlier showers have ended, but the last low- level moisture is hanging on in the form of an area of low stratus in southeast Mississippi at the moment. Low clouds and moisture will continue to decrease, with RH around 30-35 percent tomorrow afternoon and PWAT values down to less than 1/4 inch. Mid-level ridge and surface high over the eastern CONUS will reinforce the dry air in the broader region with trajectories out of the east, but moisture will wrap around the high pressure by mid to late week. Increasing PWATs along the Gulf Coast and into the High Plains will set up the atmosphere for "air mass" style afternoon shower and thunderstorm development. By late this week, the plume of deeper moisture will arc more across the Mississippi River Valley and support at least slight chance POPs mainly west of Interstate 55. Temperatures will rebound slightly above normal by mid to late week as well. /NF/
