The episode as NWS GRB wrote it up.
A very strong low pressure system moved across the region during the early morning hours of December 24th. Widespread winds of 35 to 45 mph affected central, north central, and east central Wisconsin. The strong winds blew down some trees, numerous tree branches were knocked down and thousands lost power. Some of the strongest wind gusts included: 59 mph near Whitefish Dunes State Park (Door Co.), 52 mph at Algoma (Kewaunee Co.), 51 mph in Green Bay (Brown Co.), and 46 mph near Appleton (Outagamie Co.).

NWS Green Bay, WI wrote its last area forecast discussion before the first event at Dec 23, 6:11 PM CST, 3 hours 49 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREEN BAY WI 611 PM CST WED DEC 23 2015 UPDATED AVIATION PORTION FOR 00Z TAF ISSUANCE AND NEW INFORMATION ADDED TO UPDATE SECTION .UPDATE... ISSUED AT 550 PM CST WED DEC 23 2015 MADE SOME EARLIER ADJUSTMENTS TO POPS/WX TO ACCOUNT FOR DRY SLOTTING THAT WAS OCCURRING. SHOWERS AND SCT TSTMS WILL FILL BACK IN OVER THE REGION IN ASSOCIATION WITH THE ARRIVAL OF THE POTENT NEGATIVELY-TILTED S/W TROF...SFC LOW AND COLD FRONT THIS EVG. SBCAPE/MUCAPE HAS BEEN WANING THE PAST FEW HOURS...SO NOT CONVINCED THAT WE WILL HAVE ANY SIGNIFICANT PROBLEMS WITH THE CONVECTION LIFTING NE OUT OF NE IA/NW IL. NEVERTHELESS...WILL KEEP A CLOSE EYE ON IT. SUSPECT THAT RAIN WILL RAPIDLY CHANGE TO SLEET/SNOW OVER OUR FAR WESTERN COUNTIES BETWEEN 03Z-05Z...WITH A PERIOD OF MODERATE SNOW EXPECTED OVER FAR NC WI DURING THE LATE EVENING/EARLY OVERNIGHT HOURS. THUS...THE WINTER WX ADVISORY FOR VILAS/ONEIDA COUNTIES LOOKS ON TARGET. GUSTY WINDS SHOULD QUICKLY INCREASE LATE THIS EVG...IN THE WAKE OF THE COLD FRONTAL PASSAGE. ADVISORY CRITERIA WINDS LOOK LIKE A GOOD BET...AT LEAST IN THE FOX VALLEY/LKSHR AREAS. NOT SURE THAT WE WILL REACH WARNING CRITERIA FOR DOOR COUNTY...BUT NOT PLANNING ANY CHANGES TO THE HIGH WIND WARNING AT THIS TIME. && .SHORT TERM...TONIGHT AND THURSDAY ISSUED AT 309 PM CST WED DEC 23 2015 PLENTY OF FORECAST CHALLENGES NEXT 24 HOURS CONCERNING WITH GUST POTENTIAL AND AMOUNT OF RAINFALL AND RAINFALL RATES WHICH MAY IMPACT ANY LINGERING RIVER FLOOD PROBLEMS AS WELL AS PRODUCE ANY SMALL STREAM URBAN FLOODING ISSUES. SEE THE HYDROLOGY SECTION BELOW FOR THE LATEST DETAIL ON FLOODING ISSUES. OTHER ISSUES CONCERN CHANGE OVER TO SNOW TONIGHT. A STRONG SHORT WAVE LIFTS NORTHEAST OVER THE GREAT LAKES REGION THROUGH TONIGHT. AN ASSOCIATED SURFACE LOW WILL TRACK FROM IOWA LATE THIS AFTERNOON TO CENTRAL UPPER MICHIGAN AROUND MIDNIGHT AND DEEPEN. THE LOW WILL ALSO A DRAG WARM FRONT OVER NORTHEAST WISCONSIN THIS AFTERNOON INTO THIS EVENING. MILDER AIR SPREADING INTO EAST CENTRAL AND FAR NORTHEAST WISCONSIN WILL ALLOW A VERY MILD AIR MASS WITH POSSIBLE RECORD HIGHS TO INVADE THE AREA. HIGHEST TOTAL TOTALS NUMBERS IN THE LOWER 50S MID EVENING AS PER GRB BUFKIT DATA. THIS WILL ALSO RESULT IN A MORE UNSTABLE AIR MASS AND MAY PROMOTE BETTER MIXING OF STRONG WINDS TO THE SURFACE...ESPECIALLY WITH ANY CONVECTION. HRRR PROGGED DEVELOPMENT OF THIS CONVECTION OF CONCERN ALONG AND AHEAD OF THE FRONT OVER NORTHERN MO AND SOUTHERN IOWA AND SO FAR IS VERIFYING. THIS NEXT ROUND IS PROGGED TO SWEEP OVER THE AREA THIS EVENING. PROBLEM 2 WITH THE WINDS OCCUR LATE TONIGHT AS THE DEEPENING LOW PRESSURE DEPARTS NORTHEAST AND LEAVES A STRONG PRESSURE GRADIENT OVER MUCH OF THE STATE. A STRONG PRESSURE CHANGE COUPLET SLIDES OVER NORTHEAST WISCONSIN IN THE WAKE OF THE SURFACE LOW. WILL CONTINUE WITH THE WIND ADVISORY AND WILL ISSUE FOR DOOR DUE TO THE WESTERLY COMPONENT. ITS POSSIBLE THE HIGH WIND ADVISORIES AND WARNINGS MAY NEED TO BE EXPANDED DEPENDING ON THE LOW PRESSURE TRACK. PCPN TYPE INITIALLY NOT AN ISSUE BUT COULD SEE SOME HAIL OR GRAUPEL WITH ANY CONVECTION THIS EVENING. LATER EVENING INTO THE MORNING...COLDER AIR POURING IN WILL CHANGE THE PCPN TYPE TO SNOW. WHILE SNOW RANGES MOSTLY IN THE 2-4 RANGES FOR NC WI...THE SNOW WIND COMBO WARRANTS AN ADVISORY LATER TONIGHT. RADAR SOUTHERN LOOP SUGGESTS REACHING NC WI AND CHANGEOVER AND ISSUE. BUT DID NOTICE SOME THUNDER WITH THE SURFACE LOW OVER IOWA. SYSTEM GRADUALLY DEPARTS THURSDAY WITH DIMINISHING WINDS IN THE MORNING. TEMPERATURES NEAR STEADY ON THURSDAY. .LONG TERM...THURSDAY NIGHT THROUGH WEDNESDAY ISSUED AT 309 PM CST WED DEC 23 2015 AMPLIFIED MEAN FLOW TO REMAIN INTACT THRU THE END OF THE WORK WEEK WITH AN ERN PACIFIC UPR RDG...WRN CONUS UPR TROF AND BERMUDA UPR RDG. THE UPR TROF IS FCST TO CLOSE OFF INTO AN UPR LOW OVER WEST TX THIS WEEKEND BEFORE LIFTING NE INTO THE GREAT LAKES EARLY NEXT WEEK. PCPN CHCS WL BE FOCUSED FRI NGT/SAT ASSOCIATED WITH A TIGHT BAROCLINIC ZONE/JET ENERGY AND MON NGT/TUE WITH THE UPR LOW/ ASSOCIATED SFC LOW. PCPN TYPE ISSUES WL ALSO BE A PROBLEM WITH BOTH OF THESE SYSTEMS AS TEMPS FLUCTUATE BELOW FREEZING AT NGT AND RISE ABOVE FREEZING IN PLACES DURING THE DAY. THERE IS SNOW ACCUMULATION POTENTIAL FOR CNTRL/NRN WI FRI NGT AND OVER THE ENTIRE AREA MON NGT/TUE. A WEAK AREA OF HI PRES IS FCST TO APPROACH SRN SECTIONS OF THE GREAT LAKES THU NGT AND SHOULD KEEP THE FCST AREA DRY. IT MAY TAKE MOST OF THE NGT TO TRY AND SCOUR OUT LINGERING LOW/MID-LEVEL MOISTURE...THUS PARTLY TO MOSTLY CLOUDY SKIES SHOULD SUFFICE. MIN TEMPS TO RANGE FROM THE MID TO UPR TEENS NORTH...LWR 20S CNTRL... AND MID TO UPR 20S E-CNTRL WI. THESE DRY CONDITIONS ARE EXPECTED TO PERSIST THRU CHRISTMAS DAY AS THE SFC HI SLIDES EAST TOWARD THE ERN GREAT LAKES. UNDER PARTLY CLOUDY SKIES AND RELATIVELY LIGHT WINDS...LOOK FOR MAX TEMPS TO REACH THE LWR TO MID 30S NORTH... MID TO UPR 30S SOUTH. FCST CONFIDENCE DROPS RATHER QUICKLY LATE FRI NGT INTO SAT AS AN UPR TROF DEEPENS OVER THE ROCKIES...INDIVIDUAL SHORTWAVES EJECT OUT OF THIS TROF NEWD THRU THE CNTRL CONUS...A STALLED FRONTAL BOUNDARY TO OUR SOUTH BECOMES MORE ACTIVE AND GULF MOISTURE LIFTS NORTH ALONG THIS FRONTAL BOUNDARY TOWARD THE GREAT LAKES. MODELS BRING THE LEADING EDGE OF PCPN INTO NE WI LATE FRI NGT WHEN TEMPS WL BE COLD ENUF TO ALLOW PCPN TO FALL AS ALL SNOW. THE ISSUES FOR SAT ARE WHERE THE HIGHEST QPF WL FALL AND WHAT THE PCPN TYPE WL BE. THIS IS WHERE THE MODELS DIFFER AS THE GFS/ECMWF FOCUS THE HEAVIER PCPN TO THE NORTH AND ALLOW FOR WARMER AIR TO LIFT FARTHER NORTH INTO WI...THUS A MIXED PCPN EVENT FOR CNTRL/E-CNTRL WI WITH SNOW NORTH. THE GEM IS FARTHEST SOUTH WITH THE HEAVIER PCPN (SRN WI) AND COOLER AIR...THUS KEEPING ALL OUR PCPN AS ALL SNOW. THE BETTER FRONTOGENETICAL FORCING SIGNAL AND LOCATION OF THE BEST LIFT FROM THE RIGHT ENTRANCE REGION OF THE UPR JET FAVOR NRN WI WITH THE HIGHER QPF...THUS WL CONT THE MENTION OF SNOW NORTH AND SNOW BECOMING MIXED WITH RAIN FOR CNTRL/E-CNTRL WI. POTENTIAL SNOW ACCUMULATION OF 3-5" IS POSSIBLE OVER THE NORTH FRI NGT INTO SAT...BUT ANY WAVERING ON THE STRONGER LIFT/FORCING COUDL ALTER THESE VALUES. AS THE STRONGER DYNAMICS SHIFT TO THE EAST SAT NGT...MODELS INDICATE CAA TO TAKE OVER ACROSS WI...THUS ANY LINGERING RAIN OVER CNTRL OR E-CNTRL WI WL TRANSITION TO ALL SNOW. DO NOT ANTICIPATE MUCH (IF ANY) ADDITIONAL ACCUMULATION SAT NGT AS MOST OF THE MOISTURE TO HAVE BEEN SHUNTED EAST. A STRONG AREA OF HI PRES IS FCST TO BUILD ACROSS THE UPR MS VALLEY ON SUNDAY AND SEND ENUF DRY AIR INTO WI TO ALLOW SKIES TO BECOME AT LEAST PARTLY CLOUDY. DESPITE THE CAA AND NORTH WINDS AT 5 TO 15 MPH...MAX TEMPS ARE FCST TO REMAIN ABOVE NORMAL ON SUNDAY BY AROUND 5 DEGS (MID 20S N-CNTRL TO LWR 30S E-CNTRL WI). THE CORE OF THIS STRONG HI PRES IS PROGGED TO MOVE ACROSS WRN ONTARIO SUNDAY NGT AND VEER THE WINDS TO THE NE. WL HAVE TO WATCH FOR POTENTIAL OF LK EFFECT SNOW SHWRS FROM LK MI AS TEMPS/DELTA-T VALUES WOULD SUPPORT THE DEVELOPMENT OF LIGHT SNOW. ONE NEGATIVE IS THAT THE WINDS CONT TO VEER THRU THE NGT (FROM NORTH TO E-NE)...THUS IT MAY PROVE DIFFICULT FOR SNOW BANDS TO FOCUS ON ANY ONE PARTICULAR AREA. OTHERWISE...THE OTHER BIG STORY WL BE THE APPROACH OF ANOTHER STRONG AREA OF LOW PRES/CLOSED UPR LOW INTO THE MID-MS VALLEY ON MON. LATEST THINKING IS THAT THERE WL BE ENUF DRY AIR ON GUSTY EAST WINDS FROM ONTARIO HI PRES TO DELAY THE ONSET OF ANY PCPN INTO NE WI ON MON. HAVE REDUCED POPS AND WOULD EXPECT ALMOST A COMPLETELY DRY DAY FOR MON WITH MAX TEMPS IN THE UPR 20S TO LWR 30S. MODELS CONT TO DIFFER WITH THE TIMING/EVENTUAL TRACK OF THIS STRONG SYSTEM MON NGT INTO TUE WITH THE GFS/GEM FAVORING A QUICKER/FARTHER EAST TRACK VERSUS THE SLOWER/FARTHER WEST TRACK OF THE ECMWF. THE GFS/GEM SOLUTION WOULD PROVIDE A QUICK-HITTING SNOW EVENT FOR MAINLY THE SE HALF OF WI MON NGT BEFORE PULLING AWAY ON TUE. THE ECMWF SOLUTION WOULD BRING A SWATH OF SNOW ACROSS ALL OF NE WI MON NGT BEFORE MIXING IN RAIN OVER CNTRL/E-CNTRL WI ON TUE WITH ADDITIONAL SNOWS FOR NRN WI. IF THE ECMWF SOLUTION PREVAILS...WE WOULD BE LOOKING AT HEADLINES FOR SNOW...HOWEVER THERE IS TOO MUCH UNCERTAINTY YET SO HAVE FOLLOWED A MODEL BLEND FOR NOW WITH HIGHER CHC POPS IN THE FCST FOR BOTH MON NGT AND TUE. EVEN GOING INTO WED...THERE IS MODEL DISAGREEMENT WITH RESPECT TO THE TRACK OF THE SECONDARY/WEAKER UPR LOW THAT WOULD LIFT NE INTO THE REGION. SINCE MODELS ARE INCONSISTENT WITH THIS FEATURE...PREFER TO KEEP THE FCST DRY FOR NOW...BUT WOULD EXPECT SOME SMALL POPS TO BE ADDED AS WE GET CLOSER TO WED. && .AVIATION...FOR 00Z TAF ISSUANCE ISSUED AT 550 PM CST WED DEC 23 2015 AFTER A BRIEF LULL IN THE PCPN DUE TO A DRY SLOT...SHOWERS AND SCT TSTMS ARE EXPECTED TO REDEVELOP AS A STRONG UPPER LEVEL DISTURBANCE...SURFACE LOW AND COLD FRONT MOVE THROUGH THIS EVG. TSTMS SHOULD BE MOST LIKELY IN EC WI...SO PUT TEMPO GROUPS IN THE GRB/ATW/MTW TAF SITES. AREAS OF FOG WILL AFFECT MUCH OF NC/C/NE WI THIS EVG UNTIL THE COLD FRONT MOVES THROUGH. RAIN IS EXPECTED TO CHANGE TO SLEET/SNOW OVER NC/C WI BETWEEN 03Z-05Z/THU AND PERIOD OF MODERATE SNOWFALL MAY OCCUR IN NC WI...INCLUDING THE RHI TAF SITE...DURING THE LATE EVG/ EARLY OVERNIGHT HOURS. LINGERING RAIN/SNOW SHOULD TAPER OFF MOST AREAS BY 09Z-10Z/THU... WITH CONDITIONS THEN IMPROVING TO MVFR/VFR. WILL KEEP LLWS IN THE GRB/ATW/MTW TAFS THROUGH LATE EVG... UNTIL THE COLD FRONTAL PASSAGE OCCURS. STRONG GUSTY SW-W WINDS WILL DEVELOP IN THE WAKE OF THE FRONT...AND CONTINUE THROUGH THURSDAY MORNING BEFORE DIMINISHING. GUSTS AS HIGH AS 40 KTS ARE POSSIBLE IN THE FOX VALLEY/LKSHR AREAS. && .MARINE... ISSUED AT 309 PM CST WED DEC 23 2015 HIGH-END GALES ARE STILL LIKELY WITH THIS STORM....BUT WILL MENTION STORM FORCE WIND GUSTS. IN ADDITION WILL ALSO MENTION A PERIOD OF FOG THOUGH THE EVENING HOURS. && .HYDROLOGY... ISSUED AT 309 PM CST WED DEC 23 2015 MOST RIVERS HAVE RECOVERED FROM THE HEAVY RAINS OVER A WEEK AGO...EXCEPT FOR THE LOW LYING AREAS ALONG THE WOLF RIVER SOUTH OF SHAWANO TO LAKE POYGAN. WITH THIS RAINFALL EXPECTED TO BE IN A SHORTER TIME FRAME...AN INCH OF RAIN COULD PRODUCE ENOUGH RUN OFF FOR SOME MINOR URBAN SMALL STREAM FLOODING. THIS WOLF RIVER LEVELS MAY HOLD STEADY FOR A FEW MORE DAYS WITH THIS ADDITIONAL RAINFALL. BUT LATEST RADAR TRENDS SUGGEST SOME DRY SLOTTING AS AN AREA OF ELEVATED CONVECTION IS SWEEPING NORTHEAST OF THE AREA...WITH THE NEXT ROUND OF CONVECTION APPROACHING FROM IOWA. AS A RESULT RAIN AMOUNTS TO BE LESS ROUGHLY FORM 0.30 TO 0.50. SEE WEATHER.GOV/AHPS FOR AVAILABLE FORECASTS FOR NORTHEAST WISCONSIN RIVERS. && .GRB WATCHES/WARNINGS/ADVISORIES...

SMALL HAIL AND GUSTY WINDS WILL BE POSSIBLE WITH ANY OF THE STORMS. A FEW OF THE STRONGEST STORMS COULD PRODUCE HAIL UP TO 1/2 INCH IN DIAMETER...MAINLY OVER EAST-CENTRAL WISCONSIN. STRONG SOUTHWEST TO WEST WINDS WILL DEVELOP TONIGHT. THE STRONGEST WINDS WILL BE IN EASTERN WISCONSIN...WHERE GUSTS AROUND 50 MPH ARE POSSIBLE. THE STRONG WINDS COULD BLOW ABOUT OUTDOOR OBJECTS SUCH AS GARBAGE CANS...MAKE DRIVING HIGH PROFILE VEHICLES DIFFICULT...AND RESULT IN SOME TREE DAMAGE AND ISOLATED POWER OUTAGES. COLDER AIR SURGING INTO CENTRAL AND NORTH-CENTRAL WISCONSIN TONIGHT WILL LIKELY RESULT IN THE RAIN CHANGING TO SNOW BEFORE THE PRECIPITATION ENDS TONIGHT. HAZARDOUS TRAVEL CONDITIONS COULD DEVELOP LATE TONIGHT AS ROADS BECOME SNOW OR SLUSH COVERED. .DAYS TWO THROUGH SEVEN...THURSDAY THROUGH WEDNESDAY HAZARDOUS TRAVEL IS POSSIBLE LATE CHRISTMAS NIGHT INTO SATURDAY AS ROAD CONDITIONS WILL BE DEGRADED BY SNOWFALL ACROSS PARTS OF NORTHERN AND CENTRAL WISCONSIN...AND A MIXTURE OF SNOW AND RAIN IN EAST CENTRAL WISCONSIN.
