DECAYING LINE OF SHOWERS AND THUNDERSTORMS ACROSS NORTH CENTRAL OHIO COULD STILL MANAGE TO BRING SOME SCATTERED SHOWERS TO NORTHWESTERN PENNSYLVANIA AND EASTERN OHIO LATE THIS EVENING INTO THE EARLY MORNING HOURS. EVEN AS THE LINE COLLAPSES...WILL STILL KEEP POPS IN THE FORECAST ACROSS THE NORTHERN HALF OF THE FORECAST AREA WITH THE WEAK FRONTAL BOUNDARY THAT IS APPROACHING THE REGION. NOT OVERLY CONFIDENT IN CHANCES FOR THUNDER OVERNIGHT...BUT MODEL PROFILES SHOW THAT SOME ELEVATED INSTABILITY WILL BE AROUND. CONSIDERING THE WEAK DYNAMICS...STILL NOT SURE JUST HOW WIDESPREAD COVERAGE OF SHOWERS AND STORMS WILL BE ON WEDNESDAY...ALTHOUGH LOCATIONS SOUTH OF INTERSTATE 70 SHOULD SEE MORE COVERAGE CONSIDERING THE FAVORABLE COMBINATION OF THE FRONTAL TIMING AND DAYTIME HEATING. LOCATIONS TO THE NORTH WILL BE A FEW DEGREES COOLER THAN YESTERDAY SPENDING THE ENTIRE DAY BEHIND THE COLD FRONT...WHILE LOCATIONS TO THE SOUTH COULD RISE TO TEMPS SIMILAR TO YESTERDAYS.
