DISCUSSION
Issued at 330 AM CDT Fri Jun 5 2026
Today through next Thursday...The main focus during the forecast period will be from this weekend into the middle of next week. After a couple of pleasant and quiet days across the forecast area, rain chances will return to the forecast over the upcoming weekend as a slug of moisture lifts north out of the gulf and into the Lower Mississippi River Valley, while weak disturbances move through the region. This will result in a good coverage of showers and storms developing across the forecast area both Saturday and Sunday. While currently not forecast, with precipitable H2O values over the weekend advertised in the 2-2.5 inch range, rainfall could be pretty efficient and heavy at times. As a result, some concern for flooding may arise as we move into the weekend. This will of course continue to be monitored in later forecasts.
As eluded to above, very humid conditions will also return to the forecast area this weekend, and linger into next week. This deeply moist airmass across the region next Monday through Wednesday will keep some chance for isolated to scattered afternoon convection in the forecast. It'll also be during this timeframe where the concern for heat stress will be on the rise with the subtropical ridge strengthening. As we saw recently, above normal rainfall in recent weeks will support higher boundary layer humidity and heat stress. Again, this will continue to be monitored in later forecasts. /19/EC/
