Happy Mother’s Day! Temperatures locally will not be nearly as cold today and we will see afternoon highs this afternoon at or near 60° in most neighborhoods. A cold front will advance into east-central Ohio late in the afternoon with increasing chances for showers and thunderstorms.
A line of thunderstorms is likely to set up in western Ohio late today. This line will weaken as it travels east into eastern Ohio late in the day. While I am not expecting any widespread severe weather here locally, there can be an isolates strong thunderstorm move through the Valley after 5:00 PM this afternoon. The Storm Prediction Center has our area highlighted for a Marginal Risk ( 1 out of 5) for severe thunderstorms today.
The main threat with late-day storms will be strong gusty wind and marginally large hail. Small hail will also be something to watch out for. The threat of a tornado is very low – less than 2-percent.
Chances for showers will increase through the afternoon ahead of the front. The best odds for a thunderstorm locally will be between 5:00 PM – 8:00 PM ahead and along the frontal boundary. Again, the line of storms will weaken as they advance east but storms could remain marginally severe. Simulated radar at 7:00 PM this evening:
The threat for thunderstorms will decrease after 8:00 PM as the line of storms continues moving east and exits the region. Showers will remain possible mainly until midnight with decreasing rain chances into Monday morning.
Another surge of cold air will flow in behind the front for Monday. That will bring another chilly day to the Valley with afternoon highs in the upper-40s. Temperatures again have the potential to drop below freezing Monday night and yet another Freeze Warning may be issued for portions of the area.
