ISSUED AT 120 PM CST WED NOV 26 2025
..SYNOPSIS
YESTERDAY'S SYSTEM IS NOW CENTERED OVER SAULT STE MARIE, MI
WITH NW FLOW IN THE BACKSIDE FUNNELING IN COLDER AIR AS CAN BE
NOTED BY AREA TEMPS CURRENTLY SITTING IN THE LOW TO MID 20S A
30+ DEGREE DIFFERENCE FROM THE WARM 50S AND 60S WE SAW ON
SUNDAY. FOCUSING ON JUST OUR AREA BEFORE ZOOMING BACK OUT NW
FLOW REMAINS ACROSS THE REGION WITH STILL OPEN WATER ON LARGER
AREA LAKES SUPPORTING LAKE EFFECT SNOW THE NEXT COUPLE DAYS
(PRIMARILY LAKE OF THE WOODS) WITH 1-3 INCHES OF SNOW POSSIBLE.
GOING FORWARD THE PRIMARY BAROCLINIC ZONE WILL RETREAT NORTH
SLIGHTLY AFTER BEING PUSHED WELL INTO THE PLAINS BY THIS RECENT
SYSTEM BUT REMAIN SOUTH OF AREA IN SOUTH DAKOTA AND IOWA. A LOW
WILL TRACK ACROSS THE GRADIENT FRIDAY NIGHT INTO SATURDAY BRING
WIDESPREAD SNOW TO THE NORTHERN PLAINS THOUGH ONLY CLIPPING OUR
AREA WITH FAR SE NORTH DAKOTA AND WESTCENTRAL MINNESOTA SEEING
THE MAIN IMPACTS IN OUR FORECAST AREA. AFTER THIS BROAD HUDSON
BAY TROUGHING AND AN AMPLIFIED GULF OF ALASKA RIDGE WILL PREVAIL
NW OVER THE NORTHERN PLAINS KEEPING US IN THE FREEZER WITH WIND
CHILLS FREQUENTLY IN THE NEGATIVES.
- LAKE EFFECT SNOW
SOUNDINGS AND HI-RES GUIDANCE SUCH AS THE HREF AND INDIVIDUAL
CAMS VERY SUPPORT THE FORMATION OF LAKE EFFECT SNOW ON THE
SOUTHEAST SHORE AND DOWNSTREAM AREAS OF LAKE OF THE WOODS THE
NEXT FEW DAYS. CURRENT LAKE TEMPERATURES PER RECENT SATELLITE
IMAGERY OF 34-37 DEGREE AND RESULT IN SFC TO 850MB DIFFERENCES
OF 16-17C AND SFC TO 700MB DIFFERENCES OF 22-23C. THIS FALLS
JUST SHORT OF THE MODERATE THRESHOLD OF 18C AND 24C DEFINED IN
NIZIOL 1987. COMBINE THIS VERY MINIMAL DIRECTIONAL SHEAR AND
ONLY ABOUT 20KTS OF SPEED SHEAR AND WE SHOULD GET A SINGLE
NEARLY STATIONARY LAKE EFFECT BAND. OVERALL DEPENDING WHAT YOU
LOOK AT 2-4" SEEMS TO BE WELL WITHIN THE CARDS WITH A FEW HIGH
OUTLIERS LIKE THE HRRR AND RRFS IN THE DOUBLE DIGITS. MAIN AREA
OF CONCERN WILL BE FROM BAUDETTE OR JUST EAST OF THE THERE ON
SOUTH TOWARDS BIG FALLS.
- FRIDAY NIGHT SNOW
THERE SEEMS TO BE CONSIDERABLY LESS TRACK UNCERTAINTY WITH THIS
LOW THAN THE ONE THAT JUST BROUGHT A WIDESPREAD 4-8" TO THE
DAKOTAS AND MINNESOTA ON TUESDAY. PRIMARY UNCERTAINTY WILL BE ON
WHERE MESOSCALE BANDING SETS UP WITH A LOW CHANCE FOR IT TO
SIGNIFICANTLY IMPACT OUR FORECAST AREA. HOWEVER IF YOU ARE
TRAVEL SOUTH INTO PARTS OF EASTERN SOUTH DAKOTA AND SOUTHERN
MINNESOTA THIS WILL DEFINITELY BE ONE TO WATCH FOR ADJUSTING
TRAVEL PLANS. CURRENTLY THERE IS HIGH PROBABILITY FOR AREAS
SOUTH OF A LINE FROM LISBON TO WAHPETON TO ALEXANDRIA OF AT
LEAST MINOR WINTER IMPACTS (EXPECT A FEW DISRUPTION TO DAILY
LIFE). ABOUT A 70% CHANCE FOR GREATER THAN 2" ACROSS THOSE AREAS
AND 50/50 ON MEETING ADVISORY CRITERIA FOR THOSE COUNTIES,
DEPENDING ON ANY SUBTLE TRACK SHIFTS AND HOW SHARP THE NORTHERN
QPF GRADIENT IS.
- DECEMBER DEEP FREEZE
WHILE NOT PARTICULARLY COLD BY ANY MEANS FOR WHAT WE CAN SEE
TEMPERATURE WISE IN THE REGION DURING THE PEAK OF WINTER THIS
WILL CERTAINLY BE THE COLDEST ITS BEEN SO FAR THIS SEASON. ONE
COULD VERY MUCH ATTRIBUTE THE COLD TO OUR FRESH SNOWPACK FURTHER
ENHANCING RADIATIONAL COOLING POTENTIAL. SUNDAY AND MONDAY LOOK
TO BE THE COLD WITH HIGHS NOT MAKING IT OUT OF THE TEENS AND
SOME AREAS REMAINING IN THE SINGLE DIGITS. MINIMUM WIND CHILLS
SATURDAY THROUGH NEXT WEDNESDAY WILL BE IN THE MINUS TEENS AND
LOCALLY MINUS 20S, COLD WEATHER ADVISORY CRITERIA IS -25 AND MAY
NEED TO BE MONITORED MONDAY MORNING. OVERALL IF YOU WERE HOPING
FOR WINTER YOU'RE DEFINITELY GETTING YOUR WISH BEYOND
THANKSGIVING.
