Periods of heavy rainfall, especially on Sunday, has increased the possibility for flooding in east-central Ohio.
A low pressure system will approach the region Saturday and this will bring chances for rain showers to the Tuscarawas Valley this afternoon.
Rain will continue into tonight with the main rain event arriving on Sunday with a cold front. With an abundance of Gulf moisture available the system will have the potential to produce moderate to heavy rain at times Sunday afternoon and evening.
Current computer modeling suggests that one to two inches of rain will be possible with the system. That would be enough to raise concerns for localized flooding.
A Flood Watch is in effect for the Muskingum River at Coshocton where the river is expected to reach flood stage Sunday night.
The National Weather Service in Pittsburgh indicates that additional Flood Watches and Warnings may be issued as the system approaches tonight and Sunday.
In addition to heavy rainfall, a few isolated strong thunderstorms may develop along the front. As of Saturday morning, the Storm Prediction Center has portions of the area highlighted for a Marginal Risk for severe storms.
The odds for severe storms is low, however. The limiting factor with thunderstorms on Sunday will be the lack of instability. Damaging wind gusts will be the primary threat in thunderstorms. South winds will be gusty Sunday and any thunderstorms that may develop would help increase those wind gusts.
East-central Ohio will stay in the warm sector Saturday and afternoon temperatures should reach the mid to upper 70s. Highs on Sunday will be in the upper 60s with clouds and rain around for the majority of the day. Temperatures behind the cold front on Monday will be much cooler with highs in the mid 40s. Showers and cloudy conditions will continue.
