A slow moving front will continue to push south through Ohio this evening. This front has been the focal point for scattered thunderstorm activity mainly north of Columbus through 4 p.m. Because of weak winds aloft in the atmosphere, these storms have been very slow moving. When combined with a very moist atmosphere, this results in the potential for excessive amounts of rain.
Thunderstorms will remain scattered in nature this evening meaning that not everyone will see the heavy rain. But where it does storm, several inches of rain may fall. Be aware that flash flooding can develop rapidly and you should never drive through water covered roads as you cannot tell how deep the water is.
Thunderstorms will wane in intensity later this evening after dark but showers and isolated storms will remain possible through the overnight periods. Lows will dip down into the lower 60s.
With the front just south of central Ohio on Thursday morning, a few lingering isolated showers and storms cannot be ruled out. However all of the rain should be over by early afternoon. Highs will be much cooler on Thursday only topping out in the upper 70s.
High pressure will bring very nice late spring weather to the region Friday through Sunday. We will see the humidity drop off significantly and highs will remain around 80 degrees through Saturday. Warmer air returns on Sunday with highs soaring into the upper 80s.
Looking ahead to next week, deep moisture is poised to return to the Ohio Valley. With a broad southwest flow pattern aloft and stalled frontal boundary nearby, several rounds of thunderstorms appear likely to return to our area. Stay tuned!
