A line of strong thunderstorms moved through the state this morning, leaving behind some hail and plenty of moisture. As the clouds part this afternoon and allow sunshine to filter into the region, temperatures will rise quickly, and the wind will get much stronger.
Strong flows from the south and southwest will bring in additional moisture, creating muggy conditions in the afternoon. At the same time, a deep low-pressure center moving through Central Iowa is dragging a cold front through the middle of the country. This storm system will push strong thunderstorms into Ohio late tonight and early Thursday.
This is an “all-hazards” situation with the potential for damaging winds, heavy downpours, flooding, hail, and isolated tornadoes. Parts of Ohio are under an Enhanced Risk for severe storms, Level 3 or 5. (Indianapolis is at Level 4.) It will be important to remain vigilant and #WeatherAware tonight.
The actual cold front is a slow-mover and doesn’t arrive in Central Ohio until Thursday morning. And a weak, secondary front is likely to develop behind it. Showers and thunderstorms will be likely, on and off, during the day with another round of strong storms likely in Central and Southern Ohio Thursday evening. This will be another “all hazards“ situation, and we will need to remain vigilant again. Level 2 of 5.
Showers and thunderstorms are likely again on Friday, especially in Central and Southern Ohio, as the cold front stalls out near the Ohio River. A series of low-pressure centers will track along the then-stationary front, through the Ohio River Valley. There will be a chance for some isolated strong-to-severe storms (Level 1 of 5), especially in Southern Ohio on Friday. And storms will linger through Saturday, as well.
New low pressure drags into the Great Lakes on Sunday, pushing part of the lingering system to the east. A smaller, weaker front slips through the state on Monday, bringing in much cooler air. Showers will taper off before sunrise Monday and we’ll see some gradual clearing during the day. Sunshine arrives on Tuesday and Wednesday with merciful high pressure.
