DISCUSSION

Issued at 1158 AM CDT Sat May 2 2026

Any ongoing showers and thunderstorms early this evening will quickly diminish with the loss of diurnal heating and the loss of forcing. Skies will clear and winds will become calm as high pressure briefly becomes centered over the region tonight. This will allow temperatures to dip into the upper 30s and lower 40s. However, sheltered and low-lying spots could fall into the middle 30s and see frost development. Will highlight the isolated frost potential in the HWO and social media messaging and possibly with an SPS early this evening once the convection diminishes.

On Sunday, the region will be under zonal flow synoptically, bringing seasonably warm temperatures. During the overnight hours into Monday, a shortwave will pass just north of the area, but still close enough to bring a 25-50% chance of light rain showers and a rumble of thunder or two to the Interstate 64 corridor. Areas further south may see a few showers as well. Temperatures on Monday will warm about 5-10 degrees above normal despite the rain chances.

Tuesday into Wednesday will see a return of a more active pattern. Model guidance shows a frontal boundary sagging south into the region and becoming stationary. A couple of surface lows will pass along this boundary, mainly directly over or just south of the area. This will bring a good chance (60-90%) of much-needed soaking rain and a few thunderstorms as well beginning Tuesday afternoon and evening through Wednesday evening. As this stands now, NBM ensemble guidance shows a a 60-80% chance of the region seeing at least 1 inch of rain and a 20-40% chance of over 2 inches of rain.

The placement of the frontal boundary at this time looks to keep the area cool and any thunderstorm activity elevated and non-severe. High temperatures on Wednesday and Thursday will be about 10-15 degrees below normal. As the frontal boundary exits the area dry weather will return Thursday into Friday, with southerly return flow increasing on Friday. This will bring a return of near normal temperatures.
