Strong Thunderstorms, Heavy Rainfall Possible on Friday

Posted Thursday PM, July 15, 2021

A nearly stationary frontal boundary in northern Ohio will slowly creep south on Friday raising the prospects for showers and thunderstorms in east-central Ohio Friday afternoon and evening.

With plenty of moisture and a decent amount of instability in place, some of those afternoon and evening storms could become strong to severe. The National Weather Service Storm Prediction Center has most of Ohio highlighted for a Marginal Risk (Level 1 on a scale of 1-5) for severe thunderstorms.

The main concern is strong wind gusts and downdrafts. However, with the abundant amount of moisture available for showers and thunderstorms to tap into, any that moves into your neighborhood could become an efficient rainmaker. Tropical downpours could lead to street and highway flooding.

There is a small chance we could see a morning shower or storm, but the more active period will be during the mid-afternoon and evening. While it appears that showers and storms will be scattered, those areas that do happen to get under one will have the potential for strong gusty winds and heavy rainfall.

This front looks to be a slow-mover so showers and storms may continue overnight and into Saturday morning. The odds for severe storms should decrease after sunset.

Depending on the speed of the southerly track of the front, scattered showers and storms could persist through Saturday.

Temperatures tomorrow will be warm with afternoon highs in the Valley in the mid-80s. The abundant amount of moisture will make for another humid day. That humidity will begin to decrease early next week behind the front.

The front responsible for all of this active weather is not a particularly strong one It won’t bring much of a temperature change to the area but it will bring dryer air into the region. After this front gets through Saturday or Sunday, look for a stretch of pretty nice weather coming up through mid-week. Dew points (humidity) will be somewhat less and temperatures will be in the low-to-mid-80s.

This isn’t a big severe threat but if you’re outdoors tomorrow afternoon and evening, give some notice to the weather and be prepared to get to a safe place. I’ll post updates as needed here on TUSCWeather and our Twitter feed.
