NWS Wilmington, OH wrote its last area forecast discussion before the first event at Jan 27, 12:29 AM EST, 17 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 1229 AM EST FRI JAN 27 2012 .SYNOPSIS... LOW PRESSURE CONTAINING COPIOUS MOISTURE WILL PASS ACROSS THE OHIO VALLEY TONIGHT. HIGH PRESSURE WILL BUILD INTO THE REGION ON FRIDAY. A PAIR OF WEATHER DISTURBANCES TRAVELING THROUGH THE GREAT LAKES WILL RESULT IN SOME SHOWERS ON SATURDAY AND SUNDAY. && .NEAR TERM /UNTIL 6 AM THIS MORNING/... LOW PRESSURE OVER SOUTHWEST OHIO WILL TRACK NEAR THE I-71 CORRIDOR THIS EVENING INTO EARLY MORNING BASED ON LATEST RUC/HRRR GUIDANCE. MODERATE TO LOCALLY HEAVY RAIN WILL THUS FALL IN THIS CORRIDOR. WILL CONTINUE WITH THE FLOOD WATCH UNTIL MIDNIGHT. MODELS CONTINUE TO ADVERTISE A DEFORMATION AREA OF PCPN ROTATING THROUGH THE REGION LATE TONIGHT INTO FRIDAY MORNING IN ASSOCIATION WITH A COLD FRONT AND MID LVL TROF. 00Z NAM-WRF HAS BACKED OFF ON THE TRANSITION TIME FROM RAIN TO SNOW WHICH IS CRITICAL IN TERMS OF HOW MUCH SNOW WILL FALL. HAVE TRIMMED BACK SNOW AMOUNTS SOME...NOW GOING LESS THAN AN INCH FROM CARROLLTON...TO CVG...TO ILN...TO CMH AND POINTS NW TO WEST CENTRAL OHIO. TEMPERATURES OVERNIGHT WILL BE NON DIURNAL BUT SHOULD BOTTOM OUT INTO THE LOWER 30S NW TO THE MID UPPER 30S FAR SE. && .SHORT TERM /6 AM THIS MORNING THROUGH SATURDAY NIGHT/... PCPN WILL BE EXITING THE REGION FRIDAY MORNING AS MID LVL TROF PULLS AWAY. ANY LINGERING SNOW OR RAIN/SNOW MIX SHOULD COME TO AN END BY AFTERNOON. ADDITIONAL SNOW ACCUMULATIONS WILL BE A FEW TENTHS OF AN INCH AT BEST. AM CONCERNED THAT POST FRONTAL LOW LEVEL MOISTURE MAY BE SLOW TO CLEAR AND HAVE SIDED WITH A SLOWER CLEARING TREND OF LOW LEVEL CLOUDS. SURFACE HIGH PRESSURE WILL MOVE ACROSS THE OHIO VALLEY REGION FRIDAY EVENING. THIS WILL BE BRIEF AS DIGGING S/WV ENERGY WILL MOVE TOWARD THE GREAT LAKES BY SATURDAY MORNING AS THE HIGH QUICKLY SLIDES TO THE EAST. S/WV WILL BE ASSOCIATED WITH AN ATTENDANT COLD FRONT. RIGHT NOW...IT LOOKS LIKE THERE WILL BE ENOUGH MOISTURE AND DYNAMICS FOR RAIN AND/OR SNOW SHOWERS ACRS THE FORECAST AREA STARTING IN THE WEST TOWARD SUNRISE SATURDAY MORNING AND ACROSS THE REMAINDER OF THE REGION FOR THE REMAINDER OF THE MORNING. ATTM...A QUICK INCH OF SNOW MAY BE POSSIBLE FOR NRN ZONES WITH A HALF INCH OR LESS ELSEWHERE. AIRMASS WILL QUICKLY DRY OUT DURING SATURDAY AFTERNOON...RESULTING IN A CLEARING TREND. TEMPERATURES WILL BE NON DIURNAL BUT SHOULD RANGE FROM THE MID TO UPPER 30S. A RIDGE OF HIGH PRESSURE WILL BRIEFLY BUILD INTO THE REGION FOR SATURDAY EVENING AND WILL THEN MOVE QUICKLY OFF TO THE EAST OVERNIGHT AS A DIGGING UPR TROF APPROACHES THE REGION FROM THE NW. CLOUDS WILL BE ON THE INCREASE AS WELL AS A CHANCE OF SNOW SHOWERS ENTERING THE NW ZONES TOWARD MORNING. HAVE CONTINUED WITH NON DIURNAL TEMPERATURES WITH LOWS BOTTOMING OUT IN THE LOWER TO MID 20S SATURDAY NIGHT. && .LONG TERM /SUNDAY THROUGH THURSDAY/... SUNDAY WILL BEGIN WITH THE CWA NEAR THE BASE OF A RATHER LARGE UPPER TROUGH...WITH A SURFACE TROUGH ALSO MOVING EAST THROUGH THE GREAT LAKES. WILL CONTINUE A CHANCE OF SNOW...PRIMARILY IN THE NORTH...AS THIS FEATURE PASSES. WITH THE DOME OF COLDEST AIR OVER THE REGION FOR SUNDAY AND SUNDAY NIGHT...TEMPERATURES WILL BE AT THE COLDEST OF THE ENTIRE EXTENDED FORECAST PERIOD. AS THE TROUGHING TURNS TO RIDGING ALOFT...SURFACE HIGH PRESSURE WILL MOVE INTO THE DEEP SOUTH ON MONDAY. THIS WILL ALLOW FOR LOW LEVEL FLOW TO TURN SOUTHERLY...ALLOWING TEMPERATURES TO WARM UP ABOVE CLIMATOLOGY YET AGAIN. ENERGY PUSHING IN FROM THE PACIFIC WILL SPUR THE DEVELOPMENT OF THE NEXT WEATHER DISTURBANCE FOR THE REGION...AND SIGNIFICANT DISCONTINUITIES REMAIN IN THE MODEL DEPICTIONS OF THIS PART OF THE PATTERN. WHAT IS CERTAIN IS THAT EVENTUALLY...A SURFACE LOW WILL DEVELOP AND MOVE ACROSS THE GREAT LAKES. THIS WILL PLACE THE CWA WELL INTO THE WARM SECTOR...CAUSING PRECIPITATION WITH THIS SYSTEM TO FALL SOLELY AS RAIN. DEPENDING ON THE MAGNITUDE OF THE WARM AIR...THUNDER IS NOT OUT OF THE QUESTION...BUT THIS HAS NOT BEEN EXPLICITLY FORECAST AS OF YET. AT SOME POINT BETWEEN TUESDAY NIGHT AND WEDNESDAY NIGHT...A COLD FRONT WILL CROSS THROUGH THE REGION. THE FOCUS FOR PRECIPITATION WILL BE AHEAD OF THIS FRONT. AS MENTIONED...TIMING IS STILL IN QUESTION WITH THIS SYSTEM. A HIGHER POP FORECAST WILL LIKELY BE NEEDED FOR THIS TIME FRAME...ONCE THE DETAILS ARE A LITTLE MORE CLEAR. MODEL SOLUTIONS ARE HIGHLY DIVERGENT AFTER THE PASSAGE OF THIS SYSTEM ON WEDNESDAY NIGHT...LEAVING LITTLE TO NO CONFIDENCE IN THE FORECAST FOR THURSDAY AND BEYOND. && .AVIATION /05Z FRIDAY THROUGH TUESDAY/... LOW TRACKING ACROSS THE EASTERN TAF SITES WILL CONTINUE TO PRODUCE WIDESPREAD IFR CIGS ACROSS ALL OF OUR TERMINALS THROUGH FRIDAY MORNING. VSBYS WILL TEMPORARILY IMPROVE OVER THE NEXT FEW HOURS UNTIL A COLD FRONT ARRIVES LATE TONIGHT. AS THE COLD FRONT PASSES ...WINDS WILL PICK UP FOR A BRIEF PERIOD OF TIME. VSBYS ARE EXPECTED TO DETERIORATE AFTER FRONTAL PASSAGE...WITH IFR CONDITIONS CURRENTLY OFF TO OUR WEST IN ILLINOIS AND INDIANA THAT WILL SPREAD ACROSS OUR AREA. THESE IFR VSBYS WILL LIKELY PERSIST FROM LATE TONIGHT THROUGH THE LATE MORNING HOURS. IN ADDITION...AFTER THE COLD FRONT PASSES...THERE MAY BE A BRIEF CHANGEOVER OF LIGHT RAIN TO LIGHT SNOW. THE CURRENT TIMING OF THIS CHANGEOVER APPEARS TO BE AROUND SUNRISE. CIGS SHOULD LIFT...AND VSBYS WILL IMPROVE BY THE EARLY AFTERNOON AS THE COLD AIR SCOURS OUT THE LOWEST FEW THOUSAND FEET OF THE ATMOSPHERE. OUTLOOK...MVFR CIGS/VSBYS POSSIBLE IN SNOW ON SATURDAY AND AGAIN SUNDAY. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...NONE. KY...NONE.
