Another round of showers and thunderstorms are possible late tonight into Thursday morning. Then more bad news, thunderstorms are possible during the late afternoon and evening hours Thursday too.
The first round of storms Thursday will move into the area early in the morning around 2-5 a.m and linger into the middle morning hours. The main threats with the first round of showers and thunderstorms will be heavy rainfall and gusty winds. Rainfall accumulations expected between a half-inch and an inch.
The second round of strong to severe thunderstorms are set to impact the area late in the afternoon through the evening hours. High temperatures will warm into the upper 70s with strong southerly winds bumping dewpoints into the upper 60s near 70°.
A frontal-boundary will track across the area and thunderstorms will develop along this boundary. Some of these storms could be strong to severe with the potential for strong winds, large hail, and isolated tornadoes. Right now, the KTTC viewing area is under a “Slight Risk” for severe weather tomorrow.
I would not be surprised if areas south of the viewing area (central Iowa) was upgraded to an “Enhanced Risk”.
Storms will move out of the area before midnight and calmer conditions will settle in. Highs Friday are expected in the upper 60s with mostly sunny skies.
