As an area of low pressure pushes into the Ohio Valley tomorrow it will lift warm front through eastern Ohio. Shower and thunderstorm chances will gradually increase through the morning becoming likely in the afternoon. There is a low-end threat for strong to severe thunderstorms in the Valley tomorrow afternoon and evening.
The Storm Prediction Center has highlighted the Tuscarawas Valley area for a Marginal Risk (level 1 on a scale of 1 to 5). Damaging straight-line wind gusts are the primary threat. The threat of an isolated tornado is low – but not zero.
The warm front will push very moist air into east-central Ohio. Thunderstorms will have the potential to tap into this moisture and produce heavy downpours. The National Weather Service in Pittsburgh also indicates that pockets of heavy rainfall will be possible in any storms tomorrow afternoon through Sunday. Localized flooding can be an issue in those areas with pour drainage.
The best window of opportunity of seeing a strong storm locally looks to be from about 2:00 PM through 7:00 PM tomorrow. Otherwise, scattered showers and thunderstorms will likely visit from time to time throughout the day. The trend of showers and storms will continue into the overnight hours through Sunday.
Generally, we could be on the receiving end of between a half-inch and one-inch of welcome rain from Saturday morning through Monday morning. Heavier amounts are possible in locations that get under a downpour.
Like all weather, this is an evolving situation and updates to the forecast are likely.
