Round 2

After a brief break, a second wave of strong to severe thunderstorms is expected late in the afternoon, moving east into the evening. There will be a threat for large hail, damaging winds, and tornadoes with this round of storms.

The cloud cover on Monday will impact the strength of any storms. More clouds mean cooler temperatures and lower instability, leading to a scattered, weaker severe storm threat. More sun means more warmth and greater instability, adding to the potential for more severe thunderstorms.

While the main storm threat moves out late Monday night, showers and some rumbles of thunder will linger into Tuesday. Breezy and cooler with highs in the upper 50s. Windy and chilly Wednesday. It looks sunny for the Cardinals home opener, but breezy and cool.
