Thunderstorms and Heavy Rain in the Mid-South; Heat Continues in the Southeast and Southwest

Severe thunderstorms and heavy rain are expected across portions of the mid-Mississippi Valley into the Ohio Valley and portions of Arizona. Dangerous heat persists in the South and Southeast while building into the Southwest. Overnight lows will be so warm that, when combined with oppressive dew points, little-to-no relief from the scorching daytime highs will be available. Read More >

There is a low chance of strong to severe storms this afternoon (12-8PM). Confidence is low in the occurrence of strong/severe storms, but the main hazard will be damaging winds with any that do develop. Stay weather aware! NOTE - the severe risk is a complicated scenario where there is a very low risk of severe storms with less than a 10% chance of rain in the forecast. It's contingent on IF storms well to our NW can make it far enough south. Currently, we have low confidence in this occurring.
There is a low chance of strong to severe storms Thursday afternoon and evening (2-9PM). The main hazards will be damaging winds and hail, but heavy rainfall and frequent lightning will also be threats. Stay weather aware!
Chances of showers and storms persist through Friday - some of these storms have the potential to be strong/severe on Thursday. Drier conditions and near seasonable conditions then return by Saturday. Highs in the upper 80s to lower 90s with lows in the mid 60s to lower 70s will be common through early next week.
