Warm, muggy pattern on first day of summer, rain, cooler weather coming

Forecast

A warm, sticky summer day on the last official day of spring brought a mix of sun and clouds, as temperatures edged up to 90 degrees in Columbus. Isolated showers remained well to the north closer to a frontal boundary draped over northern Lake Erie and Lower Michigan.

Summer in the Northern Hemisphere arrived at 11:32 p.m. Sunday night, when the sun reached its northernmost point in the sky, taking the greatest path from sunrise to sunset on the longest day of the year.

As developing low pressure interacts with a warm front, some storms will move across northern Ohio early tonight, a few strong to severe. As the low heads quickly into Ontario, Canada, early Monday, a strong cold front will cross the state, accompanied by broken bands of showers and some gusty storms.

A few cells could become severe Monday afternoon, with a damaging wind threat and heavy rain, during peak heating, before the front moves southeast out of Ohio in the evening, with some showers lingering behind the front Monday night. Temperatures will fall from the mid-80s to the 60s by Monday night.

Pleasantly cool and dry weather will return Tuesday behind the front, with morning clearing, as high pressure builds in from the northwest, like last week’s pattern. Highs will fall back into the 70s and mornings lows in the 50s midweek. Warmer and more humid weather will return by the weekend, with scattered showers and storms.
