Today and Saturday will be hot and miserably humid. Afternoon temperatures across the area will be in the mid-90s with dew points in the mid-70s. Despite a very humid and unstable airmass overhead, there won’t be much in the way of a trigger to generate a shower or thunderstorm. A disturbance causing severe weather up in Wisconsin today may trigger thunderstorms in northern Ohio this evening but these would likely peter out before getting too far south.
Still, the hi-res model wants to bring a little activity through around 7:00 PM this evening so, I can’t 100-percent rule out an isolated shower or storm in the area after dinner.
On Saturday a cold front will begin moving southward. Again, this might just be enough to trigger showers and thunderstorms in far northern Ohio. But, any rain activity is likely to stay well north of our area.
Sunday is a different story. That cold front will continue to inch southward and as it does, showers and thunderstorms will gradually become more likely here in east-central Ohio. Unfortunately, the models aren’t agreeing on when that might occur. For today’s forecast, I’m sticking with the slower solution and hold the showers and storms off until late-day Sunday.
If this proves to be right, it will still be hot on Sunday, just not quite as hot as Saturday.
Regardless of the timing, cooler and much drier Canadian air will move in behind the front bringing about a drastic change to our weather pattern. The hot and humid air this weekend will be replaced with refreshingly dry and cooler air. Temperatures Monday and Tuesday will be at least 15° cooler than today. Dew point in the mid-70s today will be in the 50s. With high pressure providing the sunshine, this will be some A+ weather!
SEVERE WEATHER OUTLOOK
- Friday: Hot and humid with heat index values around 107°. Severe thunderstorms are not likely.
- Saturday: Hot and humid with heat index values around 105°. Severe thunderstorms are not likely.
- Sunday: Not quite as hot, but still toasty with heat index values in the upper 90s to 100°. Will monitor for the potential for severe thunderstorms.
Have a safe weekend and stay cool!
