SOME RAINFALL RATES JUST TO THE WEST OF THE CWA HAVE BEEN AROUND 3 INCHES PER HOUR.

THE LARGEST BATCH OF STORMS THIS MORNING IS OVER NORTHERN TIER OF PA. THERE IS A PROBLEM WITH RADAR DISSEMINATION TONIGHT...SO HARD TO SEE WHAT IS COMING UPSTREAM.

THIS FRONT WILL CONTINUE THE MOVE EASTWARD AND SHOULD BEGIN TO PASS THROUGH THE CWA BETWEEN 12 AND 15Z. THERE LOOKS TO BE ABUNDANT CLOUDS AHEAD OF THE FRONT. THIS WILL HAMPER DAYTIME HEATING. THIS MAY HAMPER ANY SEVERE POTENTIAL IN THE WESTERN PORTION OF THE CWA THIS MORNING. THE MAIN THREAT AREA WILL LIKELY BE IN THE EASTERN PORTION AS IT WILL HAVE MORE TIME TO HEAT THROUGH THE DAY BEFORE THE FRONT PASSES. THE MAIN THREAT TODAY LOOKS TO BE WINDS AND POSSIBLY HEAVY RAIN. LOOKING AT THE SREF...THE FRONT SHOULD BE THROUGH THE CWA BY AROUND 18Z. BEHIND THE FRONT...THINGS SHOULD QUIET DOWN FAIRLY QUICKLY. && .SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY NIGHT/... THE WEATHER SHOULD BE QUIET TONIGHT WITH THE COLD FRONT WELL TO THE EAST. CLEARING AND COOLER AIR BEHIND THE FRONT MAY ALLOW SOME FOG TO DEVELOP IN THE VALLEYS. THE QUIET WEATHER WILL CONTINUE THROUGH FRIDAY NIGHT AS HIGH PRESSURE IS OVER THE REGION. ANOTHER WARM FRONT LOOKS TO MAKE ITS WAY INTO THE AREA SATURDAY AFTERNOON...BRINGING ANOTHER ROUND OF SHOWERS TO THE CWA.
