NWS Marquette, MI wrote its last area forecast discussion before the first event at Mar 24, 11:09 PM EST, 51 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MARQUETTE MI 1209 AM EDT WED MAR 25 2015 .SHORT TERM...(THIS EVENING THROUGH WEDNESDAY) ISSUED AT 427 PM EDT TUE MAR 24 2015 WATER VAPOR IMAGERY AND RUC ANALYSIS SHOW A COMPLEX OF SHORTWAVE ENERGY FROM THE PACIFIC NW/NRN ROCKIES INTO THE PLAINS STATES. LEAD ENERGY RESULTED IN CONVECTION ACROSS SRN MO/SRN IL TODAY. CLOSER TO HOME...SHORTWAVE RIDGE OVER THE UPPER GREAT LAKES HAS ALLOWED SFC HIGH PRES TO DOMINATE THE REGION TODAY. DRY AIR MASS/SUBSIDENCE ASSOC WITH THE RIDGE HAS RESULTED SUNNY SKIES ACROSS THE UPPER LAKES TODAY. WITH THE CENTER OF THE SFC HIGH WELL TO THE EAST...SSE WINDS OFF LAKE MI HAVE RESULTED IN COOLER TEMPS (MAINLY IN THE 30S) OVER THE EAST HALF OF THE CWA WHILE THE WARMEST TEMPS HAVE BEEN OVER THE FAR WEST WHERE READINGS HAVE MANAGED TO REACH INTO THE MID TO UPPER 40S. TONIGHT AND WEDNESDAY...ATTENTION TURNS TO THE MULTIPLE SHORTWAVES CURRENTLY MOVING ACROSS THE PACIFIC NW AND WRN PLAINS. 12Z MODELS STILL INDICATE LEAD ENERGY MOVING OUT ACROSS NE/KS THIS AFTN TAKING ON A NEGATIVE TILT AS IT MOVES TO VCNTY OF SRN LAKE MI BY 12Z WED WHILE ANOTHER SHORTWAVE MOVES ACROSS THE DAKOTAS INTO MN. THIS WILL LEAD TO 2 SFC LOW CENTERS AT 12Z WED...ONE OVER NW MN AND THE SECOND IN THE VCNTY OF SRN LAKE MI. FOR THE FCST AREA...THIS SHOULD GENERALLY MEAN THAT THE HEAVIEST PCPN WOULD PASS BY TO THE SE OF HERE...AND PCPN SHOULD FALL ALMOST EXCLUSIVELY AS SNOW AS IT ARRIVES FROM THE S AND SW LATE TONIGHT. THERE IS STILL JUST ENOUGH UNCERTAINTY IN THERMAL PROFILES (PARTICULARLY THE NAM...WHICH SHOWS A FARTHER NORTH PLACEMENT OF SECONDARY SFC LOW THAN REST OF MODELS) TO INCLUDE A MENTION OF -FZRA CLOSE TO LAKE MI AND FAR ERN PORTION OF CWA AS ABOVE FREEZING TEMPS ALOFT COULD BRIEFLY NOSE INTO THE AREA. WILL CONTINUE TO UTILIZE MOSTLY A CONSENSUS APPROACH OF ALL AVBL GUIDANCE TO CONSTRUCT POPS/QPF TONIGHT INTO WED. RESULT IS PCPN SPREADING N AND NE INTO THE FCST AREA AFTER 06Z. IT'S POSSIBLE THE SNOW MAY NOT ARRIVE OVER THE FAR N AND E FCST AREA UNTIL 12Z WED OR AFTER. SHOULD BE LOOKING AT QPF RANGES FROM LESS THAN 0.10 INCH NORTH TO 0.25 INCHES OVER SRN MNM COUNTY BY 12Z. AS NEG-TILT SHORTWAVE CONTINUES TO LIFT NE ON WEDNESDAY...MODELS SHOW HEAVIEST PCPN WILL LIFT INTO ERN COUNTIES OF THE CWA. MOST OF THE MODELS PARTICUALRLY THE NAM AND REG-GEM SHOW A SECONDARY MAX OF PCPN OVER NW MQT COUNTY AND THE HURON MOUNTAINS AREA LATE TONIGHT/WED MORNING IN RESPONSE TO REGION OF ENHANCED MID-LVL FGEN/DEFORMATION SO HAVE ALSO BUMPED UP QPF AMOUNTS OVER THIS AREA AS WELL. LOOKING AT TOTAL QPF THROUGH THE EVENT...AMOUNTS GENERALLY RANGE FROM .30 INCH OR MORE ALONG AND EAST OF A LINE FROM BIG BAY TO IRON MOUNTAIN...WITH .25 INCH OR LESS WEST OF THIS LINE. VIGOROUS DYNAMICS AND HEALTHY ISENTROPIC ASCENT NOTED ON 290K SFC SHOULD LEAD TO DECENT PCPN RATES DURING PEAK FORCING WHICH REACHES THE WI BORDER IN THE 09Z-12Z TIME FRAME. ALTHOUGH MIXING RATIOS OF 3-4G/KG ARE AVBL AROUND 750MB...SHORT DURATION OF STRONG FORCING (3-6 HRS) AND LOWER SNOW TO WATER RATIOS DOWN TO AROUND 10 TO 1 MAKE FOR LOWER CONFIDENCE ON SNOW ACCUMULATIONS REACHING ADVY LEVEL. QPF AMOUNTS COMBINED WITH SLR OF 10:1 RESULTED IN MOST OF CENTRAL AND ERN CWA STAYING BTWN 2.5 TO 3 INCHES OF SNOW. SINCE SNOW AMOUNTS SHOULD STAY JUST BLO ADVISORY FOR MUCH OF THE CENTRAL AND ERN CWA WILL JUST CONTINUE THE SPS AND EXPAND TO INCLUDE MQT-BARAGA AND DICKINSON COUNTIES. WL CONTINUE TO HIGHLIGHT POTENTIAL FOR MODERATE SNOW AND SLUSHY/SLIPPERY ROADS DURING THE MORNING COMMUTE IN SPS. SNOW WILL TAPER OFF QUICKLY FM WEST LATE MORNING/EARLY AFTERNOON AS NEG-TILT SHORTWAVE QUICKLY MOVES EAST ALLOWIN FOR DRY SLOT TO MOVE INTO UPPER MI. SOME WRAP AROUND MOISTURE ON BACKSIDE OF LOW COULD ALLOW FOR LIGHT SNOW TO LINGER INTO THE AFTERNOON HRS OVER THE NW CWA. .LONG TERM...(WEDNESDAY NIGHT THROUGH TUESDAY) ISSUED AT 339 PM EDT TUE MAR 24 2015 THE FIRST WAVE OF PRECIPITATION WILL HAVE QUICKLY SHIFTED NORTHEAST OF THE AREA ON WEDNESDAY...LEAVING THE TRAILING SHORTWAVE AND SURFACE TROUGH STRETCHING SOUTHWEST ACROSS NORTHERN/WESTERN LAKE SUPERIOR AT 00Z THURSDAY. EXPECT THERE TO BE SOME RAIN/SNOW SHOWERS OCCURRING ALONG THIS TROUGH (WETBULB ZERO HEIGHTS SUPPORT A MIX INITIALLY)...LARGELY OVER WESTERN LAKE SUPERIOR AND OVER THE KEWEENAW. THE SURFACE-850MB TROUGH WILL THEN SLOWLY SINK SOUTHEAST ACROSS UPPER MICHIGAN WEDNESDAY NIGHT...LEADING TO MUCH COLDER AIR TO MOVE INTO THE AREA UNDER NORTHERLY FLOW. 850MB TEMPS WILL DROP FROM -6C AT 00Z THURSDAY TO -11C BY 12Z AND -17C BY 00Z FRIDAY. THIS COLDER AIR WILL LEAD TO ENHANCEMENT OF THE SNOW INITIALLY...BEFORE TRANSITIONING TO PURE LAKE EFFECT DURING THE DAY ON THURSDAY AS THE DEEPER MOISTURE DEPARTS. THE LOW LEVEL WINDS WILL BE VEERING THROUGH THE WEDNESDAY NIGHT PERIOD (WESTERLY AT 00Z THURSDAY AND N-NNW BY 12Z THURSDAY)...LIMITING THE FOCUS OF THE TERRAIN ENHANCEMENT INITIALLY WEDNESDAY EVENING. AS WINDS PERSIST OUT OF THE NORTHERLY DIRECTION THROUGH THE DAY ON THURSDAY...THE TERRAIN ENHANCEMENT WILL BECOME FOCUSED AND HAVE THE HIGHEST POPS IN THE NORTHERLY WIND UPSLOPE AREAS DOWNWIND OF THE OPEN WATER ON LAKE SUPERIOR (ESSENTIALLY AROUND GOGEBIC/ONTONAGON/MARQUETTE COUNTIES). WHILE THIS WILL LEAD TO A FAVORABLE PERIOD OF LAKE ENHANCED AND UPSLOPE SNOW WEDNESDAY NIGHT INTO THURSDAY MORNING...THE SNOW AMOUNTS WILL DEPEND ON HOW QUICKLY WINDS VEER ON WEDNESDAY NIGHT. WILL FOLLOW THE GENERAL CONSENSUS ON THE TIMING...WITH THE BEST LAKE ENHANCED QPF OVER THE KEWEENAW IN THE EVENING AND SPREADING SOUTH TO GOGEBIC/ONTONAGON/MARQUETTE/BARAGA COUNTIES DURING THE OVERNIGHT HOURS. SNOW RATIOS WILL START UP AT OR BELOW 10-1 BEFORE TRENDING UP DURING THE OVERNIGHT HOURS INTO THURSDAY AS THE COLD AIR SURGES INTO THE AREA AND PUTS THE FOCUS OF THE FORCING CLOSER TO THE DGZ. ALL IN ALL...HAVE SNOWFALL AMOUNTS WEDNESDAY NIGHT INTO THURSDAY OVER THOSE PREVIOUSLY MENTIONED FAVORED AREAS OF 3 TO 6 INCHES (AND POTENTIALLY UP TO 7 INCHES OVER THE PORKIES). IN ADDITION TO THE SNOW...THE NORTHERLY WINDS WILL BE FAIRLY GUSTY ON THURSDAY (25-30KTS AND SOME GALE FORCE GUSTS OVER CENTRAL LAKE SUPERIOR)...WHICH WITH THE FLUFFIER NATURE OF THE SNOW BY THAT TIME WILL LIKELY LEAD TO SOME BLOWING SNOW ALONG THE LAKE SUPERIOR SHORELINES. AS DRY AIR FROM THE CANADIAN HIGH PRESSURE IN MANITOBA NOSES INTO WESTERN LAKE SUPERIOR ON THURSDAY AFTERNOON...EXPECT THE LAKE EFFECT TO BEGIN TO DIMINISH AND WILL START LOWERING POPS DURING THE AFTERNOON AND CONTINUE THE TREND INTO THURSDAY NIGHT. THERE DOES APPEAR TO BE A FAVORABLE PERIOD OF THE CLOUD BEING WITHIN THE DGZ LATE THURSDAY AFTERNOON INTO THURSDAY EVENING...WHICH WILL ATTEMPT TO OFFSET THE DRIER AIR AND LOWERING INVERSION HEIGHTS...BUT DON/T EXPECT THE ACCUMULATION TO BE TOO SIGNIFICANT (ADDITIONAL AMOUNTS AROUND 1 INCH ON THURSDAY NIGHT). AS THE HIGH CONTINUES SOUTH THROUGH MINNESOTA LATE THURSDAY NIGHT AND INTO WISCONSIN FRIDAY AFTERNOON...A RIDGE WILL SLIDE ACROSS THE UPPER GREAT LAKES REGION AND BRING AN END TO ANY LINGERING LAKE EFFECT FRIDAY MORNING. DRY CONDITIONS WILL PERSIST THROUGH FRIDAY NIGHT AND SATURDAY...AS THE RIDGE LINGERS OVER THE AREA AS THE HIGH MOVES INTO THE SOUTHEAST CONUS. AFTER BELOW NORMAL TEMPERATURES ON THURSDAY AND FRIDAY...SATURDAY/S TEMPERATURES WILL REBOUND TOWARDS NORMAL. FOCUS THEN TURNS TO A SHORTWAVE COMING ON SHORE IN THE PACIFIC NORTHWEST FRIDAY NIGHT. THIS WAVE WILL MOVE EAST OVER THE CANADIAN ROCKIES AND THEN EITHER THROUGH ONTARIO OR THE UPPER GREAT LAKES REGION LATE SATURDAY NIGHT AND SUNDAY MORNING. OVERALL...MODELS HAVE BEEN CONSISTENT ON THE TIMING OF THIS FEATURE...THEY JUST VARY ON THE STRENGTH OF THE UPPER RIDGE OVER THE CENTRAL/SOUTHERN ROCKIES. THE STRENGTH OF THAT RIDGE WILL DETERMINE IF THE WAVE DIVES FARTHER SOUTH AND THROUGH THE REGION OR STAYS TO THE NORTH. FEEL CONFIDENT ON THE TIMING TO SHOW MORE DETAIL IN THAT PORTION OF THE FORECAST...BUT WILL KEEP POPS STILL IN THE HIGH CHANCE CATEGORY. WILL KEEP PCPN IN THE FORECAST INTO SUNDAY AND EVEN SUNDAY NIGHT...AS THERE ARE HINTS OF A SECONDARY WAVE SWEEPING THROUGH THE AREA. THE PRECIP TYPE STILL IS A LITTLE UNCERTAIN...BUT THE INITIAL WAVE SHOULD FALL AS SNOW AND THEN MIX WITH OR TURN TO RAIN ON THE BACK SIDE. THAT POTENTIAL FOR RAIN WILL CONTINUE INTO SUNDAY...BEFORE COLDER AIR MOVES BACK INTO THE REGION AND SWITCHES ANY REMAINING PRECIPITATION BACK TO SNOW SUNDAY NIGHT. THOSE SHORTWAVES WILL SHIFT EAST OF THE AREA SUNDAY NIGHT AND ALLOW AN UPPER RIDGE TO NOSE EAST INTO THE UPPER GREAT LAKES REGION ON MONDAY BEFORE FLATTENING ON TUESDAY. THIS WILL ALLOW FOR WARMER AIR ALOFT TO WORK INTO THE AREA STARTING ON MONDAY AND ESPECIALLY ON TUESDAY (925MB TEMPS RISING TO AT LEAST 6C). THAT SHOULD PUSH HIGHS TO OR ABOVE 50 DEGREES FOR MUCH OF THE CWA FOR THE LAST DAY OF MARCH (NORMAL IS 40-45). LOOKING FARTHER AHEAD...THE PATTERN LOOKS TO TURN A LITTLE MORE ACTIVE FOR THE SECOND HALF OF NEXT WEEK...AS THE MODELS REMAIN CONSISTENT ON A STRONGER WAVE MOVE EAST TOWARDS THE GREAT LAKES REGION. && .AVIATION...(FOR THE 06Z TAFS THROUGH 06Z WEDNESDAY NIGHT) ISSUED AT 1208 AM EDT WED MAR 25 2015 DRY AIR REMAINING OVER THE NORTHERN LAKES WILL INITIALLY DELAY THE ONSET OF HEAVIER PCPN BUT THE DYNAMICS WILL BE STRONG ENOUGH FOR SNOW TO QUICKLY SPREAD OVER THE AREA AS LOW PRES LIFTS TOWARD LAKE MICHIGAN. IFR CONDITIONS SHOULD REACH KIWD BY 10Z AND KCMX BY 14Z AND THEN IMPROVE BACK UP TO MVFR BY LATE WED MORNING/EARLY AFTERNOON. KSAW HAS BEST POTENTIAL FOR HEAVIER SNOW CLOSER TO TRACK OF SFC LOW SO EXPECT VSBY TO DROP TO LIFR SHORTLY AFT 12Z AND THEN IMPROVE BACK TO MVFR BY 16Z AS SYSTEM LIFTS QUICKLY E. A SECONDARY SFC TROUGH MOVING INTO UPPER MI WED EVENING WILL BRING ADDITIONAL -SHSN WITH MAINLY MVFR CIG/VSBY. && .MARINE...(FOR THE 4 PM LAKE SUPERIOR FORECAST ISSUANCE) ISSUED AT 427 PM EDT TUE MAR 24 2015 WINDS WILL REMAIN MOSTLY UNDER 20 KT TONIGHT INTO WED AS LOW PRES TROF SETS UP ACROSS THE LAKE BTWN ONE LOW PRES CENTER MOVING E TOWARD LAKE SUPERIOR AND THE OTHER LIFTING NE THRU LWR MI INTO ONTARIO. THE TROF WILL DROP S OF THE LAKE WED NIGHT...AND WINDS WILL THEN INCREASE INTO THU AS HIGH PRES BUILDS S TOWARD THE NRN PLAINS AND MUCH COLDER AIR SPREADS SE INTO THE UPPER LAKES. NORTHERLY WINDS SHOULD INCREASE TO 20-30KT LATE WED NIGHT INTO THU...AND IT'S NOT OUT OF THE QUESTION THAT GALE FORCE GUSTS COULD OCCUR FOR A TIME OVER CNTRL PORTIONS OF LAKE SUPERIOR. WINDS WILL THEN DIMINISH FRI AS THE HIGH PRES ARRIVES OVER THE WRN GREAT LAKES. SW WINDS TO 25 KT WILL BEGIN TO RAMP UP AGAIN LATE SAT INTO SUN MORNING AS THE HIGH SHIFTS TO THE OHIO VALLEY AND LOW PRES DROPS SE FM MANITOBA TOWARD THE UPPER GREAT LAKES. WINDS TO 25 KT WL SHIFT W-NW SUN AFTERNOON BEHIND TROF PASSAGE. && .MQT WATCHES/WARNINGS/ADVISORIES... UPPER MICHIGAN... NONE. LAKE SUPERIOR... NONE. LAKE MICHIGAN...
