NWS Marquette, MI wrote its last area forecast discussion before the first event at Dec 24, 7:07 AM EST, 53 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE MARQUETTE MI 707 AM EST WED DEC 24 2008 UPDATED FOR THE 12Z TAF ISSUANCE .SYNOPSIS (ISSUED AT 413 AM EST)... 08Z WATER VAPOR LOOP AN RUC 500MB HEIGHT ANALYSIS SHOWED RIDGING OVER THE SOUTHEAST U.S....TROUGHING IN THE PLAINS...AN UPPER LOW JUST OFF SHORE OF CA AND A POTENT TROUGH DROPPING DOWN THE WEST COAST OF BRITISH COLUMBIA. UPPER MI STILL LIES IN SW FLOW BETWEEN THE CENTRAL PLAINS TROUGH AND THE SE U.S. RIDGE...BUT LACK OF ANY SHRTWVS OR ANY OTHER FORCING HAS RESULTED IN A QUIET NIGHT ON RADAR. NEAREST SHRTWV...WHICH IS ACTUALLY QUITE STRONG...IS AT THE BASE OF THE TROUGH IN SE KANSAS. ASSOCIATED WITH THE SHRTWV IS A 1007MB LOW LOCATED NEAR PEORIA IL. RADAR IMAGERY SHOWS SOME SNOW SPREADING NORTHEAST ACROSS CENTRAL IA ON THE DEFORMATION/NORTH SIDE OF THIS SFC LOW...OR ALSO IN THE DPVA AREA DOWNSTREAM OF THE SHRTWV. A SFC TROUGH EXTENDS NORTH OF THE LOW INTO WESTERN UPPER MI. BEHIND THE TROUGH...00Z SOUNDINGS SHOW COLDER 850MB AIR...WITH READINGS OF -17C AT INL AND -21C AT BIS...COMPARED TO -11C AT GRB. SFC TEMPS ALSO REFLECT THE COLDER AIR...WITH READINGS IN THE SINGLE DIGITS OR MORE BELOW ZERO IN NRN MN COMPARED TO THE TEENS ABOVE ZERO IN UPPER MI. READINGS IN UPPER MI HAVE BEEN HELD UP BY PLENTY OF CLOUDS AHEAD OF THE SFC TROUGH. NEAREST CLEARING IS OUT IN NRN MN WHERE DRIER AIR OUT OF SOUTH CENTRAL CANADA HAS BEEN WORKING ON. 00Z CYQD SOUNDING SHOWS THE DRY AIR WITH PRECIPITABLE WATER VALUES OF 0.09 INCHES AND DEWPOINT DEPRESSIONS OF 10-15C BTWN 925-750MB. THIS DRIER AIR IS ALSO ASSOCIATED WITH A RIDGE OF HIGH PRESSURE. ONLY OTHER ITEM TO NOTE IS AN UPPER LOW IN CENTRAL SOUTH DAKOTA. && .DISCUSSION (ISSUED AT 413 AM EST)... TODAY...SHRTWV OVER EASTERN KS AND THE UPPER LOW IN CENTRAL SOUTH DAKOTA ARE PROGGED TO PHASE TOGETHER AS THEY LIFT INTO LOWER MI AND LAKE HURON BY 00Z THU. THIS PHASING WILL CAUSE THE SFC LOW NEAR PEORIA TO NOT ONLY LIFT NE...BUT ALSO DEEPEN. BY 00Z THU...THE LOW SHOULD BE LOCATED IN EASTERN GEORGIAN BAY WITH A PRESSURE AROUND 995MB. THE INTENSIFICATION OF THE LOW WILL CAUSE THE DEFORMATION ZONE ON THE NORTH SIDE OF IT TO ALSO INTENSIFY...BRINGING SNOW UP THROUGH WI INTO LOWER MI. THE NORTH SIDE OF THE SNOW SHOULD STILL BE ABLE TO GET INTO THE SOUTHEAST AND EASTERN U.P....BUT AGAIN THE HEAVIEST WILL BE TO THE SOUTH OF HERE. LOCATIONS THAT DO SEE THE SNOW COULD PICK UP 2 TO 3 INCHES...WITH GFS/NAM PROGGED QPF UP TO 0.20 AND SOUNDINGS SHOWING LIFT THROUGH BOTH THE AGGREGATION AND DENDRITIC GROWTH ZONES. COULD MAKE A CASE TO GO SLIGHTLY HIGHER ON SNOWFALL AMOUNTS SINCE THE AGGREGATION LAYER IS NOT TOO DEEP...BUT OUR 00Z LOCAL WRF-ARW RUN SUGGESTED THAT THE LOW TRACK COULD END UP FARTHER SOUTH AND THEREFORE KEEP MORE OF THE PCPN OUT OF UPPER MI. ANOTHER AREA THAT WILL SEE SNOW IS NORTHERN UPPER MI...IN THIS CASE LAKE EFFECT. AS THE LOW INTENSIFIES...IT HELPS TO BRING IN THE COLDER AIR OUT OF NRN MN...WHICH IS SHOWN BY 850MB TEMPS PROGGED TO DROP TO -12 TO -16C BY 00Z. IN FACT...950MB CONVERGENCE FIELDS SHOW THE POSSIBILITY OF A SINGLE BAND DROPPING SE ACROSS LAKE SUPERIOR... APPARENTLY CONNECTED TO THE CURRENT TROUGH OVER WESTERN UPPER MI. THIS SOUNDS REASONABLE AND HAVE TRIED TO INCORPORATE IT INTO THE FORECAST. BAND SHOULD IMPACT WRN UPPER MI THIS MORNING AND THEN NORTH CENTRAL AND NORTHEAST UPPER MI IN THE AFTERNOON. MULTI-PARALLEL BANDS ARE EXPECTED TO DEVELOP IN THE WAKE OF THE BAND. OVERALL...SNOWFALL AMOUNTS OF 1 TO 3 INCHES FROM THE LAKE EFFECT SEEM POSSIBLE...A LOT OF IT DUE TO THE SINGLE BAND. HIGHS TODAY SHOULD BE ABLE TO CLIMB INTO THE 20S AT MOST PLACES (EXCLUDING THE FAR WEST)...BUT THESE ARE LIKELY TO OCCUR AROUND 18Z BEFORE THE COOL AIR COMES IN TO CAUSE READINGS TO FALL SLIGHTLY. TONIGHT...PHASED UPPER LOW AND SHRTWV DO NOT LOOK TO HANG AROUND THE GREAT LAKES REGION TOO LONG. IN FACT...BY 12Z THU...THEY SHOULD BE IN THE CANADIAN MARITIMES. WITH ITS RAPID DEPARTURE...VERY LITTLE IF ANY SYNOPTIC SNOW IS EXPECTED AFTER 00Z. THEREFORE ATTN TURNS TO LAKE EFFECT. 850MB TEMPS WHICH DROPPED TO THE -12 TO -16C RANGE LATE TODAY ARE PROGGED TO STAY ABOUT STEADY...OR POSSIBLY EVEN RISE LATE IN THE NIGHT. THIS RISE IS A RESULT OF RETURN FLOW ON THE BACK SIDE OF THE SFC RIDGE CURRENTLY OUT IN THE PLAINS...WHICH IS EXPECTED TO MOVE INTO IL...WI AND UPPER MI AROUND 12Z. THEREFORE... MULTI-PARALLEL BANDS DURING THE EVENING WITH ONE OR TWO ENHANCED BANDS DUE TO LAND BREEZES SHOULD GRADUALLY WEAKEN AND LIFT TO THE NORTHEAST. THE WEAKENING WILL BE ENHANCED BY DRY AIR MOVING IN AND LOW LEVEL FLOW TURNING ANTICYCLONIC. AREAS MOSTLY IMPACTED BY THE BANDS SHOULD BE IN WESTERN UPPER MI AND THOSE EAST OF MARQUETTE. A GENERAL 1 TO 2 INCHES SEEMS REASONABLE...GIVEN THE WEAKENING TREND OF THE BANDS AND THEIR CONSTANT MOVEMENT. OUTSIDE OF THE LAKE EFFECT...INLAND AREAS SHOULD CLEAR OUT. WITH DRY AIR MOVING IN AND CLEAR SKIES...THE STAGE IS SET FOR GOOD RADIATIONAL COOLING. WILL CONTINUE TO GO BELOW GUIDANCE FOR LOWS...WHICH COULD DROP TO NEAR 10 BELOW NEAR THE WI BORDER. CHRISTMAS DAY...UPPER TROUGH DROPPING DOWN THE BRITISH COLUMBIA COAST IS PROGGED TO ALL THE WAY SOUTH INTO SRN CA BY 00Z. AS THIS OCCURS...THE UPPER LOW CURRENTLY OFF THE CA COAST GETS SHUNTED EASTWARD INTO THE CENTRAL PLAINS. THE PRESENCE OF BOTH FEATURES SUGGESTS BUILDING RIDGING DOWNSTREAM...WHICH WILL BE MOVING UP INTO THE GREAT LAKES DURING THE DAY. THE COMBINATION OF SUBSIDENCE UNDER THE BUILDING UPPER RIDGE AND DRY AIR ASSOCIATED WITH THE SFC HIGH WILL RESULT IN MOSTLY SUNNY SKIES. IN ADDITION...WITH RETURN FLOW INCREASING AS THE SFC RIDGE MOVES OFF TO THE EASTERN GREAT LAKES...850MB TEMPS ARE ALLOWED TO CLIMB TO -5 TO -10C BY 21Z. WITH SUNSHINE AND SOUTH WINDS PICKING UP...TEMPERATURES SHOULD BE ABLE TO CLIMB INTO THE 20S AGAIN. THE COLD START WILL PROBABLY KEEP READINGS IN MOST PLACES FROM REACHING TODAYS HIGHS...WITH THE EXCEPTION BEING THE FAR WEST. ALSO TO NOTE IS THAT THE 850MB TEMPS ARE ALMOST WARM ENOUGH TO END THE LAKE EFFECT...ALTHOUGH MOST OF IT WILL BE MOVING OFFSHORE ANYWAY BY 18Z. THU NIGHT INTO FRI...UPPER TROUGH OVER THE WESTERN U.S. WILL BE MARCHING EASTWARD DURING THIS PERIOD...COMING CLOSE TO THE PLAINS STATES BY 00Z SAT. AS THE TROUGH MOVES EAST...THE UPPER LOW CURRENTLY OFF THE CA COAST IS LIFTED NORTHEASTWARD...OF COURSE IN A SHEARED BUT STILL IN A SIGNIFICANT STATE. THE SHEARED UPPER LOW SHOULD REACH UPPER MI FRI MORNING. DPVA FORCING AND INCREASING ISENTROPIC LIFT AHEAD OF THE LOW...ALONG WITH A GOOD MOISTURE FEED OUT OF THE GULF OF MEXICO...WILL SUPPORT BANDED PCPN MOVING INTO UPPER MI DURING THE OVERNIGHT HOURS OF THU NIGHT INTO FRI MORNING. SOUNDINGS SUGGEST THAT THE DENDRITIC GROWTH ZONE IS GOING TO BE QUITE HIGH...ALLOWING FOR MORE AGGREGATION AND THEREFORE LOW SNOW TO WATER RATIOS. EVEN SO...A SOLID 2 TO 3 INCH SNOW LOOKS LIKE. CONTINUED THE PREVIOUS FORECAST MENTION OF CATEGORICAL POPS...AND ACTUALLY WENT AHEAD AND PUT SOME ADDITIONAL FINE TIMING INTO THE FORECAST. NEXT PROBLEM IS MID-LEVEL DRYING THAT OCCURS BEHIND THE SHEARED UPPER LOW AS IT HEADS INTO NE ONTARIO. THIS DRYING REMOVES ANY ICE NUCLEI...BUT GFS/NAM ISENTROPIC LIFT PLOTS ON THE 285K SFC AS WELL AS 800-900MB FRONTOGENESIS FIELDS CONTINUE TO SHOW LIFT PRESENT. IN ADDITION...WITH THE SFC-950MB WIND FLOW OUT OF THE SE...THIS PROVIDES UPSLOPE ENHANCEMENT TO SOME AREAS OF UPPER MI. SO IT LOOKS FAVORABLE FOR EITHER RAIN OR FREEZING RAIN. EXPECTATION IS THAT IN THE WAKE OF THE SHEARED UPPER LOW THAT PCPN WILL TRANSITION TO FREEZING RAIN...THEN AS THE SFC TO 850MB LAYER WARMS...PCPN GRADUALLY CHANGES OVER TO RAIN IN THE AFTN. HOWEVER...THERE DEFINITELY COULD BE A PERIOD OF ICE ACCUMULATION...PROBABLY ONLY ENOUGH TO WARRANT AN ADVISORY. REGARDING TEMPS...LOWS ON THU NIGHT SHOULD BE IN THE EVENING (NOT FAR FROM THUS HIGHS)...THEN RISE THROUGH THE REST OF THE NIGHT INTO FRIDAY AS SOUTH WINDS ADVECT WARMER...MOIST AIR INTO THE CWA. HIGHS ON FRIDAY ARE TRICKY AND HAVE MAJOR IMPLICATIONS ON WHEN FZRA CHANGES TO RAIN. BUMPED UP READINGS CLOSER TO GFS/NAM MOS GUIDANCE...WHICH BRINGS TEMPS TO OR ABOVE FREEZING. MAV GUIDANCE FOR IWD IS QUITE WARM...37...BUT DID NOT GO THAT HIGH YET. GIVEN THE INCREASING MOISTURE/WARM TEMPS...ADDED SOME PATCHY FOG IN UPSLOPE AREAS. FRI NIGHT INTO SAT...MODELS ARE NOW IN MUCH BETTER AGREEMENT WITH REGARDS TO THE WESTERN TROUGH PROGRESSION EASTWARD...EXCLUDING THE CANADIAN WHICH LOOKS TO BE A FAST OUTLIER. MUCH OF THE CWA FRI NIGHT SHOULD BE UNDER WARM ADVECTION...AHEAD OF A LOW PRESSURE SYSTEM MOVING OUT OF THE PLAINS AND INTO NW ONTARIO. THE ASSOCIATED COLD FRONT IS INDICATED TO MOVE INTO FAR WRN UPPER MI BY 12Z SAT. THIS MEANS TEMPS FRI NIGHT SHOULD BE ON THE RISE...THEN FALL BACK LATE IN THE FAR WEST WITH THE FRONTAL PASSAGE. PCPN WISE...MAJORITY OF THERMODYNAMICAL AND DYNAMICAL FORCING WILL BE TO OUR SE...WITH CONVECTION PROBABLY OCCURRING IN LOWER MI AND SE WI. WILL STILL KEEP SOME LOW CHANCE POPS...THOUGH...GIVEN STILL SOME REMAINING WEAK LOW LEVEL ISENTROPIC LIFT. PCPN TYPE SHOULD BE MOSTLY RAIN...ESPECIALLY WITH SFC TEMPS WARMING ABOVE FREEZING AND 850MB TEMPS CLIMBING TO 4-7C BY 12Z SAT OVER MOST AREAS. ON SAT...COLD FRONT MARCHES ACROSS UPPER MI WHILE THE LOW PRESSURE AREA LIFTS INTO FAR NRN ONTARIO. GIVEN THE LOW TRACK...PCPN IS NOT VERY FAVORABLE WITH THE AREA LIKELY IN A MID-LEVEL DRY SLOT WITH COLD ADVECTION IN THE LOW LEVELS. 850MB TEMPS MAY COOL DOWN ENOUGH TO RESULT IN SOME WEAK LAKE EFFECT SNOW SHOWERS...BUT THAT IS ABOUT IT. DUE TO THE FRONTAL PASSAGE...TEMPS IN THE WESTERN U.P. WILL FALL THROUGH THE DAY. IN THE EAST...SOME WARMING IS POSSIBLE IN THE MORNING TO GET HIGHS UP NEAR 40 BEFORE THE FRONT CROSSES. GIVEN THE WARM UP...WILL NEED TO WATCH FOR WATER ON ROADS FREEZING ON SAT. NO OTHER CHANGES MADE BEYOND SAT. && .AVIATION (FOR THE 12Z TAF ISSUANCE)... LIGHT SNOW HAS STARTED TO FALL AT CMX...AS WELL AS WFO MQT WHICH MEANS THAT IT IS NOT TOO FAR OFF FROM SAW. LOOKING AT THE LATEST SAT IMG AND REPORTED CONDITIONS UPSTREAM OVER WI AND IOWA...THE CURRENT FORECAST OF CEIGS/VIS DROPPING INTO IFR CAT BY 18Z LOOKS REASONABLE AS THE SFC LOW STRENGTHENS AND CROSSES INTO LOWER MI. AS THE LOW EJECTS NE...WINDS WILL TURN W/SW TOWARDS 09Z THURSDAY ...ENDING LAKE ENHANCEMENT WITH VFR CEIGS/VIS FIGURED THEREAFTER. && .MARINE (FOR THE 4 AM LAKE SUPERIOR FORECAST ISSUANCE)... LOW PRESSURE WILL REORGANIZE AND STRENGTHEN SLIGHTLY BY EARLY EVENING ACROSS EASTERN JAMES BAY...AND QUICKLY MOVE TO SOUTHEASTERN CANADA BY DAYBREAK THURSDAY. THIS COULD BRING WINDS TO 30 KNOTS...MAINLY OVER CENTRAL AND EASTERN LAKE SUPERIOR THIS EVENING. HIGH PRESSURE OVER THE MIDDLE MISSISSIPPI RIVER VALLEY THIS EVENING SHOULD SHIFT OVER THE OHIO VALLEY THURSDAY...ALLOWING A RIDGE OF HIGH PRESSURE TO SWING ACROSS LAKE SUPERIOR...AND MOVE TO THE LOWER GREAT LAKES BY THURSDAY EVENING. ALSO THURSDAY EVENING AND FRIDAY...GALES TO 35 KNOTS WILL BECOME POSSIBLE ONCE AGAIN OVER THE CENTRAL AND EAST AS THE PRESSURE GRADIENT INCREASES BETWEEN THE HIGH AND THE FORTHCOMING LOW. FOR FRIDAY...EXPECT LOW PRESSURE DEVELOPING ACROSS THE CENTRAL PLAINS TO SURGE NORTHEASTWARD TO WESTERN MINNESOTA FRIDAY EVENING...AND DEEPEN SUNDAY MORNING ACROSS HUDSON BAY. THIS MAY BRING GALES TO 35 KNOTS TO THE WEST HALF SATURDAY INTO SATURDAY NIGHT. SUNDAY...HIGH PRESSURE WILL STRENGTHEN ACROSS THE SOUTHERN PLAINS. && .MQT WATCHES/WARNINGS/ADVISORIES...
