WINDS ACROSS MOST OF THE AREA.
- RAIN TRANSITIONS TO SNOW FROM WEST TO EAST FROM LATE

POSSIBLE. WINDS GUSTING AS HIGH AS 40-45MPH WILL RESULT IN
BLOWING SNOW, REDUCED VISIBILITY, AND DIFFICULT TRAVEL
OVERNIGHT.

LATER IN THE DAY, WITH COLD BUT OTHERWISE QUIET WEATHER TO END
THE WEEK.

TODAY WILL BE THE MOST INTERESTING WEATHER DAY WE HAVE EXPERIENCED
OVER THE LAST FEW MONTHS WITH FOG EARLY, RAIN DURING THE DAY TURNING
INTO SNOW LATER ON, AND SIGNIFICANT BLOWING SNOW DUE TO GUSTY WINDS.
TO START WITH WHAT IS HAPPENING NOW, WE ARE FIRMLY WITHIN THE LOW
LEVEL SOUP WITH LOW LEVEL STRATUS AND FOG OVERSPREADING THE AREA
THIS MORNING, WITH VISIBILITY DUE TO FOG DOWN TO BELOW A MILE IN
SPOTS ACROSS THE AREA. A FEW SPOTS HAVE DROPPED DOWN TO 1/4 MILE
NAMELY ACROSS PORTIONS OF SOUTH-CENTRAL MN FROM MANKATO AND
EASTWARDS, WITH MOST OF THE AREA GENERALLY 2 MILES OR HIGHER. THE
CLOUD DECK IS JUST OFF THE GROUND AS LOW AS AROUND 200FT, SO EVEN
IN SPOTS THAT ARE NOT SEEING SIGNIFICANT FOG DEVELOPMENT, THE CLOUD
BASE IS LOW ENOUGH THAT IT WILL FEEL AS THOUGH THERE IS NO
VISIBILITY REGARDLESS. FOG ISN'T EXPECTED TO GO ANYWHERE UNTIL RAIN
SHOWERS BEGIN TO OVERSPREAD THE AREA, WHICH GENERALLY OCCURS FROM
WEST TO EAST FROM LATE MORNING TO MIDDAY AS THE LEADING EDGE OF THE
INCOMING TROUGH REACHES WESTERN MINNESOTA.
THE HIGH RESOLUTION GUIDANCE FROM 00Z LAST NIGHT THROUGH THIS
MORNING REMAINS AGGRESSIVE ON AN OVERALL SOUTHWARD SHIFT FROM PRIOR
GUIDANCE CLOSER TO WHAT THE AIFS HAS BEEN PUSHING FOR THE LAST 4-5
DAYS, RESULTING IN SIGNIFICANT UPGRADES TO NOT ONLY SNOW AMOUNTS
ACROSS MUCH OF THE AREA BUT OVERALL IMPACTS. THE UPPER LEVEL TROUGH
SWINGS THROUGH WITH A SURFACE LOW DEVELOPING AS IT DOES, WITH
SIGNIFICANT LOWER-MID LEVEL CAA CRASHING TEMPERATURES INTO THE DGZ
BY 22-23Z IN WESTERN MN AND 00-01Z IN THE TWIN CITIES. THESE
CRASHING TEMPERATURES WILL RESULT IN EFFICIENT SNOWFALL PRODUCTION
AS WE SATURATE THE DGZ AND STILL SEE STRONG FORCING DUE TO THE UPPER
LEVEL TROUGH AND SURFACE LOW, WITH SNOW RATES EXCEEDING 1 INCH PER
HOUR POSSIBLE FROM THE ONSET OF SNOWFALL. A TROWEL SHOWS UP WITHIN
MOST OF THE HIGH RESOLUTION GUIDANCE CONTINUING TO LEAD TO HIGHLY
EFFICIENT SNOW PRODUCTION, WITH A BRIEF DRY SLOT POSSIBLE MAINLY IN
PORTIONS OF SOUTHERN MN AS THE RAIN MOVES OUT AND THE SOUTHWESTERN
EDGE OF PRECIPITATION WRAPS AROUND. THE HEAVIEST SNOWFALL WILL OCCUR
WITHIN THE 2-3 HOURS AFTER IT TRANSITIONS FROM RAIN, HOWEVER LIGHT
SNOW LOOKS TO CONTINUE AT LEAST INTO EARLY WEDNESDAY IF NOT
LINGERING THROUGH SUNRISE AND INTO THE AM COMMUTE. STRONG SURFACE
WINDS ARE EXPECTED TO FORM AS THE SURFACE LOW STRENGTHENS, RESULTING
IN WINDS INCREASING TO 20-30MPH WITH GUSTS AS HIGH AS 40-45, EVEN
50MPH IN SPOTS FROM THE NORTH TO NORTHWEST FROM THE AFTERNOON
ONWARDS. SNOW RATIOS IN THE RANGE OF 15/18 TO 1 COULD BE REDUCED BY
THE STRONG WINDS, BUT GENERALLY WE CAN EXPECT THE HIGHEST SNOW
AMOUNTS IN CENTRAL MN WHERE THE STRONGEST BAND IS MOST LIKELY TO
MOVE THROUGH WITH THE LOWEST AMOUNTS STILL IN SOUTHERN MN. THE RANGE
LOOKS TO BE ON THE ORDER OF 6-8 INCHES ACROSS OUR NORTHERN CWA, DOWN
TO 2-4 INCHES IN SOUTHERN MN AND WESTERN WI FROM PIERCE TO
EAU/CHIPPEWA BASED OFF NOT ONLY THE BLENDED GUIDANCE BUT ALSO INPUT
FROM CAMS. THIS MAY BE AN EVENT WHERE SNOW TOTALS CAN VARY
SIGNIFICANTLY BASED ON LAND USAGE AND WHERE ONE MEASURES, AS THE
STRONG WINDS WILL MAKE IT DIFFICULT TO FIND FLAT AREAS THAT ARE NOT
AFFECTED BY DRIFTING AND BLOWING SNOW. GENERALLY, IF YOU'RE PLANNING
ON TRAVELING BEFORE THE HOLIDAYS OVER THE NEXT FEW DAYS, OUR
RECOMMENDATION WOULD BE TO LEAVE EITHER EARLY TODAY OR WAIT UNTIL
LATER ON WEDNESDAY AFTER THE WINDS DIMINISH AND BLOWING SNOW BECOMES
LESS OF A CONCERN.
GUSTY WINDS PERSIST THROUGH DAYLIGHT WEDNESDAY, RESULTING IN FURTHER
SLOW TRAVEL DUE TO BLOWING SNOW THAT IMPROVES AS WINDS DIMINISH
WEDNESDAY NIGHT. TEMPERATURES AT THE SURFACE WILL CRASH INTO THE
TEENS BY THANKSGIVING MORNING AS SKIES ALSO BEGIN TO CLEAR OUT ON
TOP OF THE FRESH SNOWPACK, WHICH OFTEN CAUSES COOLER TEMPERATURES
THAN GUIDANCE PREDICTS AS DEW POINTS CAN DROP LOWER THAN EXPECTED.
THESE COLD TEMPERATURES GENERALLY REMAIN LOCKED IN THROUGH THE REST
OF THE PERIOD AND INTO EARLY DECEMBER WITH SOME GUIDANCE SHOWING
SINGLE DIGIT LOWS THE FIRST WEEK OF THE MONTH. ANOTHER CHANCE FOR
LIGHT SNOW ARRIVES FRIDAY NIGHT INTO SATURDAY WITH A CLIPPER TYPE
FEATURE SLIDING ACROSS THE AREA, FEATURING A WEAK UPPER LEVEL TROUGH
AND SURFACE LOW. UNTIL WE GET THROUGH THE SHORT TERM SYSTEM,
CONFIDENCE REMAINS LOW NOT ONLY IN PLACEMENT BUT STRENGTH OF ANY
MESOSCALE FEATURES, SO STAY TUNED FOR FURTHER INFORMATION ON WEEKEND
TRAVEL IMPLICATIONS. BEHIND THE WEEKEND CHANCES, WE LOOK TO BE DRY
INTO EARLY NEXT WEEK AS A STRONG ARCTIC HIGH MOVES ACROSS THE AREA
EARLY IN THE WEEK, LEADING TO THE AFOREMENTIONED SINGLE DIGIT
TEMPERATURES AND KEEPING THE COLD AIR LOCKED IN.

THE WINTER STORM IS STILL ON TRACK AND ALREADY LOOKING
IMPRESSIVE ON IR SATELLITE IMAGERY AND ROAD CAMERAS ACROSS THE
DAKOTAS. LIFR/IFR CONDITIONS CONTINUE ACROSS MUCH OF MINNESOTA
INTO WESTERN WISCONSIN WITH CEILINGS HOVERING AROUND 300-600FT.
VISIBILITIES HAVE IMPROVED, THOUGH THERE ARE STILL POCKETS OF
1/2SM FOG/MIST ALONG THE MINNESOTA RIVER VALLEY AND INTO
EASTERN MINNESOTA. LIGHT RAIN IS STARTING TO FILL IN ACROSS
CENTRAL MINNESOTA, WITH SNOW MOVING INTO PARTS OF WESTERN
MINNESOTA (INCLUDING AT AXN ALREADY). AS THE SYSTEM SHIFTS EAST,
RAIN WILL QUICKLY TRANSITION TO HEAVY SNOW. EXPECT VISIBILITIES
TO DROP RAPIDLY AS WINDS BEGIN TO GUST UP TO NEAR 40KTS OUT OF
THE NORTHWEST.
THE SNOW WILL END OVERNIGHT FOR WESTERN AND CENTRAL MINNESOTA,
AND THEN TAPER OFF DURING THE MORNING FOR EASTERN MINNESOTA AND
WESTERN WISCONSIN. WINDS WILL STILL BE GUSTING TO NEAR 35 KTS
TOMORROW, SO PERIODS OF BLOWING SNOW WILL BE POSSIBLE THOUGH
VISIBILITIES ARE NOT EXPECTED TO DROP BELOW MVFR.
KMSP...THIS WILL BE A ROUGH TAF PERIOD WITH IMPACTS FROM HEAVY
FALLING SNOW, STRONG NORTHWEST WINDS LEADING TO PERIODS OF
BLOWING SNOW, AND LOW CEILINGS LASTING THROUGH TONIGHT. RAIN WILL
TRANSITION TO SNOW AROUND 02Z, AND WILL BECOME HEAVY AT TIMES
WITH HOURLY RATES APPROACHING 0.5 TO 1 INCH/HR. HAVE
INTRODUCED A 3 HOUR WINDOW OF 1/2SM VIS AS CONFIDENCE IN HEAVY
SNOWFALL RATES HAS INCREASED IN COMBINATION WITH THE STRONG
NORTHWEST WINDS BLOWING SNOW AROUND. SNOW WILL TAPER OFF BY
EARLY TOMORROW MORNING, WITH LINGERING IMPACTS FROM BLOWING SNOW
POSSIBLE THROUGH THE REST OF THE MORNING.
