AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MARQUETTE MI 326 PM EST WED JAN 24 2007 .SHORT TERM DISCUSSION (CURRENT THRU THU)... 12Z RAOBS/LATEST WV IMAGERY AND RUC ANALYSIS SHOW HI AMPLITUDE WRN RDG/ERN TROF UPR FLOW WITH POSITIVE PNA/NEGATIVE NAO PATTERN LOCKING COLD AIR IN PLACE OVER ERN NAMERICA. TWO SHRTWVS OF CONCERN EMBEDDED WITHIN THIS FLOW. THE FIRST IS CURRENTLY DROPPING FM MANITOBA INTO NW ONTARIO...AND THE SECOND IS MOVING FM HUDSON BAY INTO NW ONTARIO. AREA OF THICKER CLD/SOME -SN ASSOCIATED WITH FIRST SHRTWV/DPVA/H85-5 QVECTOR CNVGC IS NOW MOVING INTO THE WRN CWA...BUT OVERALL PCPN COVG/INTENSITY LIMITED BY DRY AIR SHOWN ON THE 12Z INL/YPL/YQD RAOBS AND MINIMAL ISENTROPIC LIFT. BACK EDGE OF THICKER CLD ASSOCIATED WITH THIS SHRTWV IS MOVING STEADILY S THRU NW ONTARIO...SFC DWPT NEAR -20F AT YPL. FARTHER E...LES BANDS ARE PUSHING INTO THE NW SN BELTS E OF MQT AS COLD AIR TO THE NW (12Z H85 TEMP AT YPL -21C) FLOWS ACRS THE RELATIVELY WARM WATERS OF LK SUP. ALTHOUGH THESE BANDS APPEAR TO BE GETTING MORE DISORGANIZED WITH INCRSD WIND SHEAR AHEAD OF SHRTWV...SOME REFLECTIVITIES STILL AOA 28DBZ IN WRN MOST BAND OVER WRN ALGER COUNTY IN AXIS OF LLVL CNVGC BTWN MORE WLY FLOW ACRS THE WCNTRL CWA AND ELY FLOW OFF ONTARIO FARTHER TO THE E. EARLIER SPOTTER REPORT NEAR AU TRAIN INDICATED SN FALLING AT THE RATE OF AN INCH/HR UNDER THIS BAND. NO WX AND HARDLY ANY CLD ASSOCIATED WITH SECOND SHRTWV AS 12Z MOOSONEE RAOB SHOWS PWAT ONLY 0.06 INCH. MAIN FCST CONCERNS IN THE SHORT TERM REVOLVE ARND LES TRENDS AND AMTS/GOING HEADLINES/NEED FOR ADDITIONAL HEADLINES. TNGT/THU...SHRTWV MOVING FM MANITOBA FCST TO MOVE INTO NRN WI BY 00Z AND THEN INTO THE OH VALLEY BY 12Z THU. SECOND SHRTWV FCST TO REACH NR ANJ BY 12Z THU BEFORE MOVING INTO NY STATE BY 00Z FRI. ALTHOUGH DPVA/H85-5 QVECTOR CNVGC BEHIND FIRST SHRTWV WL BE EXITING THE FA BY EARLY THIS EVNG...EXPECT LES IN THE COLD NNW FLOW IN THE WAKE OF THIS SHRTWV TO BE ONGOING DOWNWIND OF LK SUP. GFS FCST SDNGS SHOW FAIRLY DEEP MSTR AT 00Z INCLUDING FVRBL SN GROWTH LYR UP TO H6 OVER THE E WITH FAIRLY UNIDIRECTIONAL NNW FLOW BLO INVNR AS HI AS H8. IN ADDITION TO EARLIER ADVY ISSUED FOR GOGEBIC/ONTONAGON ZNS AND WRNG FOR ALGER COUNTY WHERE LLVL CNVGC WL BE MOST PERSISTENT ALG EXISTING SFC TROF...WL POST ADVY FOR MQT/SCHOOLCRAFT/DELTA COUNTIES TO ACCOUNT FOR FVRBL NLY FLOW AND DPVA/SOME H85-5 QVECTOR CNVGC ACCOMPANYING PASSAGE OF SECOND SHRTWV LATER OVER THE E. SINCE THESE DYNAMICS WILL MISS THE WRN ZNS (SECOND SHRTWV TRACKING WELL TO THE E) AND ARRIVING DRIER AIR BEGINNING TNGT WL HAVE A SHORTER FETCH OVER WRN LK SUP...ADVYS FOR WRN ZNS ONLY NECESSARY THRU 12Z THU... WHEN GFS FCST SDNG FOR IWD SHOWS INVRN BASE AT 12Z THU FALLING TO H9. CONSIDERED ADVY FOR LUCE COUNTY AS WELL...BUT SHORTER FETCH WITH BONE DRY AIRMASS UPSTREAM/POORER SN GROWTH WITH H85 TEMPS FALLING TOWARD -25C BY 12Z THU SUG HEADLINE NOT NECESSARY THERE. EXPECT LES TO DIMINISH EVEN OVER THE ERN ZNS LATER ON THU WITH APRCH OF SFC HI PRES/MORE ACYC FLOW/LOWERING INVRN BASE TO H9. AS FOR TEMPS...STRONG NLY FLOW TNGT/LK SUP MODERATION SHOULD HOLD TEMPS UP HIER TNGT THAN MIGHT BE EXPECTED FOR INCOMING DRY AIR. EXPECT LOWEST TEMPS OVER THE ERN ZNS WITH POTENTIAL LAND BREEZE OFF ONTARIO. LO END OF MOS GUIDANCE SEEMS MORE APPROPRIATE FOR HI TEMPS ON THU. COORDINATED WITH DLH/GRB. KC .LONG TERM (THURSDAY NIGHT THROUGH WEDNESDAY)... SLEET OR FREEZING DRIZZLE FOR THURSDAY NIGHT INTO FRIDAY? AT THIS TIME...THIS SEEMS MORE LIKELY TO OUR SOUTH...AND WHILE UTILIZING THE GFS...WITH MORE MOISTURE AND COOLER AIR OVER OUR AREA...WILL KEEP SNOW ACROSS THE UPPER PENINSULA. THE 500MB RIDGE SHOULD BE DIRECTLY OVERHEAD AROUND 18Z FRIDAY. STILL...WITH THE UPSTREAM LOW GEARING UP TO SINK TOWARDS UPPER MICHIGAN...AN EXTENDED DRY PERIOD IS NOT FIGURED AS THE SURFACE HIGH PRESSURE CENTER IS LONG GONE...AND OVER THE EASTERN GREAT LAKES BY THIS TIME. AS FOR FRIDAY NIGHT...OUR FORECAST TEMPS SEEMED TOO LOW WHEN COMPARED TO UPDATED MODEL DATA. WENT AHEAD AND ADJUSTED UP FROM 1-3 DEGREES ACROSS THE BOARD...WHICH IS STILL TOWARDS THE LOWER END OF GUIDANCE VALUES. CAA WILL BE MOVING IN AT THIS TIME...AS THE CLIPPER SYSTEM MOVES OUT OF OF SOUTHEASTERN MANITOBA FRIDAY...AND OVER THE EASTERN THIRD OF LAKE SUPERIOR BY O6Z SATURDAY. WE MAY NEED TO MAKE FURTHER ADJUSTMENTS TO THE TEMPERATURES FOR THIS PERIOD...AS I HAVE HAVE A HARD TIME BELIEVING THAT WE WOULD BE ABLE TO CLEAR OUT...TO REALIZE THE COOLER GUIDANCE TEMPS CLOSE TO OUR CURRENT FORECAST WITH THE AMOUNT OF LOW LEVEL MOISTURE BEING PRODUCED BY THE MODELS FRIDAY NIGHT INTO SATURDAY MORNING. POP WISE FOR FRIDAY NIGHT...WITH DISCREDITING THE NAM WHICH HAD PROBLEMS IN THE NEAR TERM WITH TEMPERATURES OVER THE CWA...AND THE FACT THAT DURING THE FRIDAY INTO SATURDAY TIME PERIOD THAT IT IS FURTHER NORTH AND EAST OF A MAJORITY OF THE OTHER MODELS...HAVE A HARD TIME GOING WITH ANY DRY AREAS. STILL...BELIEVE THAT THE BEST CHANCE FOR ANY PLACE TO STAY DRY WILL BE ACROSS THE SOUTH...SO HAVE MANIPULATED THE POP AND WEATHER GRIDS ACCORDINGLY. COOLER AIR WILL SLIDE INTO THE AREA...AS NOTED PREVIOUSLY...WITH 850MB TEMPERATURES FALLING FROM ROUGHLY -10C AT 00Z SATURDAY TO -22C BY 12Z SUNDAY (THEN CONTINUING AROUND THIS MARK THROUGH MONDAY AFTERNOON). AS THIS COOLER AIR SLIDES IN...AND WE HAVE AN EXTENDED PERIOD OF NORTH TO NORTHWESTERLY FLOW NEAR THE SURFACE...WE WILL NEED TO CONTINUE MONITORING FOR THE POSSIBILITY OF ENHANCE PRECIPITATION DUE TO LAKE EFFECT...PARTICULARLY 12Z SATURDAY THROUGH 00Z SUNDAY ENHANCED BY THE COLD FRONT SLIDING SOUTHWARD ACROSS THE FORECAST AREA. OTHERWISE FOR SUNDAY THROUGH WEDNESDAY (DAYS 4 - 7)...COOLER HAS BEEN THE TREND TODAY...ADJUSTING TEMPERATURES FROM DAY 4 (SUNDAY) ON DOWNWARD. FOR THE MOST PART...DID NOT DEVIATE MUCH FROM HPC GUIDANCE FOR THIS PERIOD...WITH ONLY SMALL SCALE ADJUSTMENTS DEEMED NECESSARY AT THIS TIME. THE PRELIMINARY AND FINAL GUIDANCE CONTINUES TO DEVIATE FROM THE NAM...AND FOLLOWS THE GFS FOR THE MOST PART OVER OUR REGION. && .MQT WATCHES/WARNINGS/ADVISORIES...
