NWS Wilmington, OH wrote its last area forecast discussion before the first event at Feb 4, 6:37 PM EST, 1 hour 23 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 637 PM EST WED FEB 4 2009 .SYNOPSIS... HIGH PRESSURE WILL BUILD INTO THE REGION TONIGHT. THIS HIGH WILL MOVE EAST OF THE AREA ON THURSDAY. A RETURN FLOW AROUND THE HIGH WILL BRING A WARMING TREND TO THE LOWER GREAT LAKES AND OHIO VALLEY INTO THE WEEKEND. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... NEAR TERM FORECAST ISSUES WILL REVOLVE AROUND SKY COVER...CHANCES FOR SNOW SHOWERS AND OVERNIGHT LOWS. RADAR MOSAIC AND SATELLITE IMAGERY WERE SHOWING CLOUDS AND A FEW SNOW SHOWERS COMING OFF OF LAKE MICHIGAN TOWARD THE FORECAST AREA. IT IS STILL UNCLEAR ATTM ON HOW MUCH AND HOW LONG ASSOCIATED CLOUDS AND LIGHT PCPN WILL LINGER ACRS THE WRN FCST AREA THIS EVENING INTO EARLY MORNING. HAVE KEPT A SLIGHT CHC FOR SNOW SHOWERS MAINLY ACROSS THE WRN ZONES THIS EVENING. AS SFC HIGH PRESSURE BUILDS INTO THE OHIO VALLEY REGION OVERNIGHT...LOW LVL FLOW WILL EVENTUALLY BACK...CUTTING OFF ANY LAKE EFFECT CLOUDS/PCPN...RESULTING IN CLEARING SKIES. THE RECENT SNOWFALL ALONG WITH DIMINISHING WINDS OVERNIGHT...WILL ALLOW THE NORMALLY COLDER LOCATIONS TO DROP BELOW ZERO. ALL OTHER LOCATIONS WILL GENERALLY FALL INTO THE 0 TO 5 ABOVE RANGE. THESE VALUES ARE COLDER THAN ANY OF THE AVAILABLE MOS GUIDANCE. EVENING SHIFT WILL HAVE A BETTER IDEA ON CLOUDS...WINDS AND TEMPERATURE TRENDS SHOULD OVERNIGHT LOWS NEED TO BE ADJUSTED DOWN A LITTLE MORE THAN CURRENTLY FORECAST. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY/... SFC HIGH PRESSURE WILL MOVE EAST OF THE REGION ON THURSDAY. THIS WILL MARK THE BEGINNING OF A WARMING TREND. SKIES FOR THE MOST PART WILL BE MOSTLY SUNNY. MOST MOS GUIDANCE TEMPERATURES WERE FAIRLY SIMILAR TO EACH OTHER. DUE TO A COLD START AND THE LACK OF A FULL DAY OF DEEP LOW LVL WAA...HAVE STAYED CLOSE TO OR SLIGHTLY BELOW MOS GUIDANCE VALUES. THIS WILL RESULT IN HIGHS RANGING FROM THE LOWER 20S NORTH TO THE UPPER 20S SOUTH. FOR THURSDAY NIGHT INTO FRIDAY...MODELS ARE HINTING AT THE POTENTIAL FOR LOW LVL CLOUDS TO FORM ACROSS THE REGION WITHIN A MOIST...LOW LVL WAA/ISENTROPIC REGIME. UNFORTUNATELY...THEY ALSO OFFER DIFFERENT SOLUTIONS ON TIMING AND LOCATION FOR THE POTENTIAL CLOUD COVER. BUFKIT MODEL SOUNDINGS INDICATE THAT LOW LVL CLOUDS MAY INDEED FORM. SINCE CONFIDENCE AT THIS POINT IS NOT HIGH AND DUE TO THE DIFFERENCES IN TIMING/LOCATION OF POTENTIAL CLOUDS...HAVE OPTED TO KEEP SKIES MOSTLY SUNNY/MOSTLY CLEAR TO PARTLY SUNNY...KEEPING IN MIND THAT THIS MAY NEED TO BE ADJUSTED TO MOSTLY CLOUDY IF LATER RUNS CONTINUE TO SUPPORT THE FORMATION OF LOW LVL CLOUDS. A MODEST LOW LVL SOUTHERLY FLOW ACROSS THE REGION THURSDAY NIGHT WILL KEEP OVERNIGHT LOWS FROM DROPPING TOO FAR OFF FROM THURSDAY/S HIGHS. DECENT LOW LVL WAA ON FRIDAY WILL BOOST HIGHS INTO THE MID 30S NORTH TO THE MID 40S SOUTH. FOR FRIDAY NIGHT...MID LVL S/WV WILL PIVOT EAST TOWARD THE GREAT LAKES. CONTINUED MOIST...LOW LVL WAA WILL CAUSE CLOUDS TO INCREASE. THERE MAY BE A SLIGHT CHANCE OF SHOWERS ACROSS THE NW CWFA DUE TO THE LOW LVL MOIST...WAA REGIME. LOWS WILL RANGE FROM THE MID 30S TO LOWER 40S. && .LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/... DEEP UPR TROFFING DVLPG ALONG THE PACIFIC COAST THIS WEEKEND WILL SPURN DOWNSTREAM RIDGING ACRS MUCH OF THE ERN CONUS AND PROMOTE A PATTERN SHIFT FROM THE PERSISTENT AND VERY COLD WEATHER THE OH VLY HAS EXPERIENCED FOR THE LAST SVRL WEEKS. MID LVL S/WV AND ASSOCD SFC LO WILL PASS THRU THE NRN GRT LKS SAT AND DRAG A TRAILING COLD FRONT THRU THE FCST AREA SAT NIGHT. SRLY FLO AHEAD OF THIS SYSTEM IS WEAK...WITH PCPN EXPECTED TO REMAIN VERY LIGHT AS ISENTROPIC LIFT WILL BE MAIN SOURCE OF FORCING. HAVE HELD ONTO 20-30 POPS FOR WDLY SCT -SHRA WITH FROPA. DUE TO THE WEAK NATURE OF THE FRNTL BNDRY AND THE PRESENCE OF DEEPENING UPR RIDGING OVER THE SE STATES...FRONT LIKELY TO STALL OUT JUST SOUTH OF THE FCST AREA SUNDAY AS SFC HI PRES CENTERS PASS TO THE NORTH AND SOUTH OF THE REGION. WILL MAINTAIN 30 POPS ACRS SRN FCST AREA BUT AGAIN...OVERALL FORCING NOT TERRIBLY IMPRESSIVE AND PCPN SHOULD REMAIN LIGHT AND SCATTERED. WITH AFOREMENTIONED SFC HI PASSING THRU GRT LKS SUNDAY...APPEARS ENUF DRY AIR WILL FILTER INTO NRN FCST AREA TO HELP BREAK UP SC DECK AND ALLOW FOR SOME SUNSHINE. S/WV EJECTS FROM THE UPR TROF SITTING OVER SRN CALIFORNIA SUN NIGHT AND HELPS SPIN UP A SFC LO IN THE WESTERN HIGH PLAINS ON MON. THIS WILL PROMOTE FURTHER RIDGING IN THE UPR LVLS ACRS THE REGION AND HELP TO PUSH THE FRNTL BNDRY BACK NORTH ACRS THE REGION AS A WARM FRONT. REINTRODUCE 30 POPS FOR MON AS FRNTL BNDRY LIFTS THRU. BOTH OP GFS/ECMWF INDCG MUCH OF THE REGION SHOULD WORK INTO THE WARM SECTOR SOUTH OF THE BNDRY FOR MON AFTN/NIGHT. PATTERN BECMG INCREASINGLY ACTIVE FOR THE END OF THE FCST PERIOD AS AFOREMENTIONED SFC LO LOOKS TO BE THE FIRST IN A SERIES OF SYSTEMS TO AFFECT THE REGION. THE SFC LO WILL MOVE NORTHEAST INTO THE UPR MISSISSIPPI VLY ON TUES AND BEGIN OCCLUDING. INCREASE TO HI CHC POPS LATE MON NIGHT INTO TUES AS ATTACHED FRNTL BNDRY TRACKS THRU THE REGION. GREATER DIFFERENCES BEGIN TO CROP UP IN THE VARIOUS MODELS FOR TUES AND WED REGARDING HANDLING OF ADDL S/WV ENERGY EJECTED FROM DEEP WEST COAST TROF. OP GFS AS WELL AS A NUMBER OF THE GFS ENSEMBLE MEMBERS EJECTING ANOTHER PIECE OF UPR LVL ENERGY TUES/WED AND TRAVERSING ACRS THE CNTRL PART OF THE COUNTRY. ECMWF HOLDING MORE ENERGY BACK IN THE WRN TROF AND THUS RELEASING IT ABOUT 1-2 DAYS BEHIND THE OP GFS. REGARDLESS OF THE TIMING DIFFERENCES...MOST MODELS INDCG AN EXTENDED PERIOD OF SOUTHWEST FLO IN THE UPR LVLS. THIS UPR LVL PATTERN IN THE WINTER IS NOTORIOUS FOR MILD AND WET WX FOR THE OH VLY AS THE SUBTROPICAL JET USUALLY TRACKS INTO THE REGION. THE POTENTIAL FOR HEAVIER RAINFALL BECOMES A POSSIBILITY IF A LINGERING BNDRY EXISTS IN THE AREA...SUCH AS WILL EXIST NEXT WEEK. FOR THAT REASON...THE POTENTIAL FOR AN EXTND PERIOD OF RAINFALL IS THERE FOR THE TUE-THURS TIME FRAME. TO ADD TO THE MIX...MODELS HINTING AT SOME ELEVATED INSTABILITY WORKING INTO THE REGION TUES/WED WHICH WOULD SUPPORT A CONVECTIVE ELEMENT TO PCPN AND POSSIBLY A FEW TSTMS. WITH THIS SERIES OF SYSTEMS STILL 6-8 DAYS OUT FOR THE OH VLY...NOT GOING TO GET TOO DETAILED AT THIS POINT AND JUST HAVE 40-50 POPS WITH NO MENTION OF THUNDER. TEMPS WILL REMAIN ABV NORM THRU THE PERIOD WITH HIGHS IN THE 40S/50S. && .AVIATION /00Z THURSDAY THROUGH MONDAY/... NW FLOW OVER OHIO VALLEY IS BRINGING A CONVERGENT BOUNDARY WITH SCT SHSN FOUND EMBEDDED IN A NARROW BAND OF BKN SC CLOUDS. ON ONCCASION...THESE CLOUDS ARE SHOWING CIGS DROPPING BELOW 3KFT. I AM HIGHLY SUSPICIOUS OF VSBYS BEING REDUCED IN THE -SHSN AND WILL NOT ACCOUNT FOR THIS AS THE SHOWERS THEMSELVES WILL BE VERY WIDELY SCATTERED FOR THE NEXT FEW HOURS. SFC WINDS WILL TURN SW FOR ALL BUT CMH/LCK FAIRLY EARLY THIS EVENING AS HIGH PRESSURE SETTLES OVER THE WESTERN OHIO VALLEY. DO NOT THINK THAT THE SHIFT AND SUBSEQUENT LESSENING WILL HIT CMH GROUPING...AND I KEPT THE CHANCES FOR THE LAKE BAND OF CLOUDS AND -SHSN OUT OF THIS AREA TOO. WAA ON THE BACK SIDE OF THE SFC HIGH PRESSURE WILL TURN OFF ANY LOW CLOUDS OVERNIGHT TONIGHT...AT THE VERY LATEST AFTER DAYBREAK TOMORROW TOWARDS CMH. ENOUGH MOISTURE WAS NOTEDE TO BE HANGING AROUND 1500-2KFT TOMORROW TO INCLUDE FEW/SCT CU DURING THE DAY. ISENTROPIC LIFT ON BACKSIDE OF HIGH WILL BRING SCT-BKN CI THU. OUTLOOK...MVFR CIGS/VSBYS SATURDAY INTO SUNDAY. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...NONE. KY...NONE.
