forecast for first half of week

– frontal boundary to remain in region throughout forecast period

– periods of thunderstorms each day with severe weather threats

– risk for flash flooding by Wednesday night

A frontal boundary which has been nearly stationary along the Ohio river will shift slightly northward Sunday night and Monday. Another round of showers and storms will be likely from Sunday afternoon into the overnight hours as this boundary shifts north, locally heavy rain and isolated severe storms are possible. During the day Monday isolated storms are still expected along the boundary instability present may allow a few of these to reach severe limits with a threat for gusty winds and hail. A low pressure system will enhance the coverage of showers and storms late Monday night with another threat for heavy rain( up to 1.5 inches from Sunday afternoon-Monday night)and severe weather in the form of gusty winds. Once again during the day Tuesday coverage of storms becomes more scattered with a continued isolated severe threat. A stronger low pressure system will track over the region along the boundary late Tuesday night through Wednesday night. These features will enhance the heavy rain threat and lead to a likely widespread additional 2 to locally 4 inches of rain which may result in flash flooding. In addition severe storms are possible on the leading edge of this system in the form of gusty winds and isolated tornadoes. With a almost constant threat for severe weather and likely hydrological hazards throughout the forecast period the STN will remain on alert for the foreseeable future. Further statements for severe watches and warnings, activations and flood warnings may be needed. lows will be in the 60’s with highs in the 70’s and 80’s.
