The Ohio Valley is in the midst of an active weather pattern this week. We saw several rounds of showers and isolated thunderstorms Sunday night through Monday night. However a much stronger weather system could bring widespread severe thunderstorms to the region Wednesday.

A slow moving frontal boundary will push across Columbus this afternoon. This front will be bisecting the area around lunch time. As the afternoon progresses, a broken line of thunderstorms may begin to develop along the front. The highest chance for storms will be southeast of Columbus, but a pop up storm cannot be ruled out anywhere. It will be another warm day with highs in the middle 80s.

Any threat for rain will end by 6 p.m. and it looks like a very nice evening is on tap. Behind the front, the humidity will temporarily drop off. Temperatures will also fall into the 70s under clearing skies this evening. All eyes then turn to the west as a nasty batch of storms develops over the Plains states.

A vigorous low pressure area will slide east across Indiana and Ohio on Wednesday. This low will spark a very strong batch of storms (called a Mesoscale Convective System or MCS for short) well to our west Tuesday evening. What happens with this initial batch of storms is somewhat in question, but the remnants could bring some rain and thunder to the region Wednesday morning.

With some sunshine peaking back out late Wednesday afternoon and strengthening wind fields aloft (due to the incoming low pressure system), the atmosphere will turn extremely ripe for all types of severe weather.

The highest risk will be between 5 p.m. and 9 p.m. Wednesday night. Widespread damaging winds and scattered large hail will be the primary threats along with torrential rainfall. However, isolated tornadoes are a good possibility as well particularly southwest of Columbus. In fact, the highest severe threat will be near and south of I-70 Wednesday evening.

Where tonight’s thunderstorms complex ends up tomorrow will morning will have major implications to the forecast for our storms tomorrow evening. That means adjustments to the forecast are still possible. Stay with examiner.com for the latest updates.

Much nicer weather returns for the end of the week with highs falling back into the 70s along with lower humidity.
