AN UPPER LEVEL DISTURBANCE WILL CROSS THE OHIO VALLEY THIS EVENING AND BRING SHOWERS AND THUNDERSTORMS TO THE AREA. HIGH PRESSURE WILL BRING MAINLY DRY WEATHER FOR MONDAY INTO TUESDAY. A COLD FRONT WILL CROSS THE AREA TUESDAY NIGHT, BRINGING THE CHANCE OF SHOWERS AND THUNDERSTORMS FOR TUESDAY NIGHT INTO WEDNESDAY. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... 4PM UPDATE: ADJUSTED TEMPS AND SKY COVER TO BETTER FIT TRENDS. ADJUSTED POP USING LAPS RADAR AND HRRR...WHICH REDUCESS POP TO SLIGHT CHANCE BY LATE EVENING. THE AXIS OF A POSITIVE-TILTED 500MB TROUGH EXTENDS FROM EASTERN ONTARIO SOUTHWESTWARD ACROSS OHIO. THIS FEATURE AND THE VORT ENERGY ROTATING AROUND IT ARE PROVIDING FORCING IN A MODERATE INSTABILITY ENVIRONMENT (LAPS SBCAPE AROUND 1500 J/KG) FOR SCATTERED CONVECTION ACROSS THE AREA FOR THE REMAINDER OF THE AFTERNOON. THIS EVENING...CONVECTION WILL CONTINUE TO INCREASE IN COVERAGE INTO THE EARLY EVENING AS THE TROUGH MOVES CLOSER TO THE AREA. PWAT VALUES 115% OF NORMAL SUPPORT LOCALLY HEAVY DOWNPOURS WITH STORMS, ALTHOUGH INCREASING SOUTHWESTERLY WINDS ALOFT WILL KEEP STORMS MOVING COMPARED TO THE LAST SEVERAL DAYS. THUS, QPF IS AROUND A TENTH TO A QUARTER OF AN INCH. LOCALIZED AMOUNTS OF 1 TO 2 INCHES ARE STILL POSSIBLE HOWEVER. TONIGHT...THE HRRR AND THE NAM12 BOTH SUPPORT CONVECTION QUICKLY DIMINISHING AFTER 00Z WITH INSTABILITY DECREASING AND THE TROUGH AXIS CENTERED ACROSS WESTERN PA. THERE WILL BE SOME LINGERING CONVECTIVE DEBRIS CLOUD COVERAGE OVERNIGHT. WITH THIS IN MIND, OVERNIGHT LOWS ARE A FEW DEGREES ABOVE MAV/MET GUIDANCE, RANGING FROM NEAR 60 ACROSS THE LOWLANDS TO THE MID 50S ACROSS THE RIDGES AND PORTIONS OF EASTERN OHIO. && .SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY/... THE MID-LEVEL TROUGH WILL PUSH INTO THE MID-ATLANTIC STATES ON MONDAY WITH A WEAK AREA OF HIGH PRESSURE ATTEMPTING TO BUILD IN FROM THE SOUTHERN APPALACHIANS. ABUNDANT LOW-LEVEL MOISTURE MAY SERVE TO TRIGGER A FEW AFTERNOON ISOLATED SHOWERS ACROSS THE EASTERN RIDGES. OTHERWISE, MONDAY AND MONDAY NIGHT WILL BE DRY ACROSS THE AREA. NAM/GFS 850 TEMPS OF 13-14C SUPPORT THAT HIGHS MONDAY WILL A FEW DEGREES ABOVE NORMAL. LOWS MONDAY NIGHT WILL BE NEAR NORMAL VALUES. TUESDAY...ECMWF/NAM/GFS AGREE THAT A COLD FRONT WILL DROP SOUTHEASTWARD ACROSS THE GREAT LAKES, WITH WARM AIR ADVECTION IN AN ENHANCED SOUTHWESTERLY FLOW AHEAD OF THIS FEATURE. THERE ARE SOME DIFFERENCES IN TIMING AND STRENGTH OF THE FRONT, WITH THE NAM/ECMWF SOLUTIONS MUCH SLOWER WITH A NORTHWESTERLY WIND-SHIFT. WITH THE SLOWER SOLUTIONS IN MIND, HAVE A DRY FORECAST UNTIL TUESDAY EVENING WHEN SCHC POPS ARE INTRODUCED. STRONG WAA AHEAD OF THE FRONT WILL ALLOW FOR HIGHS TO WARM TO AROUND 5 DEGREES ABOVE NORMAL, RANGING FROM THE LOWER 80S IN THE LOWLANDS TO THE MID 70S IN THE RIDGES. TUESDAY NIGHT AND WEDNESDAY...THE COLD FRONT WILL CROSS THE AREA WITH A MID-LEVEL TROUGH AND STRONGER COLD AIR ADVECTION LAGGING BEHIND THIS FEATURE. WITH THE FRONT POTENTIALLY CROSSING THE AREA AT A DIURNALLY UNFAVORABLE TIME AND SOME MODEL VARIANCES, HAVE JUST GONE WITH CHC POPS WITH ITS PASSAGE TUESDAY NIGHT. SCHC POPS ARE FORECAST WEDNESDAY WITH COLD AIR ADVECTION AND THE MID-LEVEL TROUGH POSSIBLE TRIGGERING ISOLATED SHOWERS. TEMPERATURE FORECAST IS CHALLENGING TUES NIGHT WITH TIMING OF FRONT, BUT BELIEVE COLDEST AIR WILL BE LAGGING STILL. THUS, LOWS TUESDAY NIGHT RANGE FROM THE MID 50S NORTHWEST OF PITTSBURGH TO NEAR 60 IN NORTH-CENTRAL WV. TEMPS WILL BE SLOW TO RECOVER WITH CLOUD COVERAGE AND COLD AIR ADVECTION ON WEDNESDAY. HIGHS WILL BE AROUND 5 DEGREES BELOW NORMAL, RANGING FROM THE MID 60S ACROSS THE I-80 CORRIDOR TO NEAR 70 FOR AREAS SOUTH AND WEST OF PITTSBURGH. && .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
