A large area of arctic high pressure moved southward across the Upper Midwest the evening of Tuesday, February 1st, and continued through the morning of February 2nd. The combination of very low temperatures, and wind speeds averaging around 10 mph, created wind chill values between 35 and 45 below zero across west central and portions of southwest and south central Minnesota.
Every event with a place to put it; 12 filed by county or forecast zone are drawn at its center, in a lighter ring. Tap one for its entry below.
Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN
532 PM CST TUE FEB 1 2011
.UPDATE...
UPDATED TO INCLUDE 00Z AVIATION DISCUSSION BELOW.
&&
.DISCUSSION...
/ISSUED 356 PM CST TUE FEB 1 2011/
A MASSIVE CYCLONE TO THE SOUTHEAST IS DRAWING MUCH OF THE WEATHER
ATTENTION...AND RIGHTFULLY SO. WHILE THE FORECAST CONCERNS ARE
SOMEWHAT MINUSCULE COMPARED TO THOSE...BLOWING AND DRIFTING
SNOW...ALONG WITH WIND CHILLS REMAIN CHALLENGES TONIGHT INTO
WEDNESDAY FOR THE LOCAL AREA.
THE PERFECTLY STRUCTURED CYCLONE WITH ITS MID-LEVEL LOW LOCATED
IN MO CONTINUES TO LIFT NORTHEAST. THE BAROCLINIC LEAF SHIELD ON
SATELLITE CHANNELS EXTENDS NORTHWARD OVER THE FORECAST AREA. GIVEN
WATER VAPOR PROJECTIONS THIS WILL CONTINUE TO EXPAND OVER THE
REGION THIS EVENING...BEFORE RETREATING AS THE SYSTEM HEADS EAST
OVER THE LOWER GREAT LAKES. KDMX RADAR CONTINUES TO SHOW
BLOSSOMING AREA OF SNOW HEADING NORTHWARD. SHORT TERM RADAR
PROJECTIONS BRING REFLECTIVITY INTO SOUTHERN MN...AND ISENTROPIC
ASCENT IS SEEN DOWN TO 10 KFT OVER THE FEW LOWER TIERS OF
COUNTIES. LOW LEVEL NORTHERLY WIND MAY MAKE IT TOUGH...BUT LOOKING
AT CROSS SECTIONS THERE IS SLOPED F-GEN AND NEAR NEGATIVE EPV
WITHIN THAT ISENTROPIC OMEGA LAYER. SO CONTINUE A TIGHT GRADIENT
IN SNOW CHANCES IN THAT FAR SOUTHERN STRETCH OF COUNTIES.
CALLS TO EMERGENCY MANAGERS AND MONITORING OF WEB CAMS HAS
INDICATED THAT WHILE AUTOMATED AND DRIVING VISIBILITIES ARE
GENERALLY GOOD...THE SHALLOW LAYER OF BLOWING SNOW
CONTINUES...ESPECIALLY ALONG WEST TO EAST ORIENTED ROADS. WIND
SPEEDS WILL ACTUALLY INCREASE SOMEWHAT THIS EVENING AS THE CYCLONE
IS AT ITS CLOSEST POINT TO THE FORECAST AREA. THE PRESSURE
GRADIENT FORCE WILL FURTHER BE MAXIMIZED AS THE 1052 MB HIGH
SHIFTS SOUTHEAST FROM WESTERN ND. WITH THE LOW DEEPENING TO NEAR
995 MB...A 55 MB PLUS GRADIENT WILL EXIST ACROSS ACROSS A
BASICALLY THREE STATES. SO DO EXPECT SHALLOW BLOWING AND DRIFTING
SNOW TO CONTINUE ACROSS WESTERN AND SOUTHERN MN TONIGHT AND
POTENTIALLY INTO THE MORNING...WITH THE GREATER IMPACTS HAPPENING
IN SOUTH CENTRAL MN THIS EVENING. SO HAVE EXTENDED WINTER WEATHER
ADVISORY THERE.
WESTERN MN BASICALLY DID NOT CLIMB IN TEMPERATURES TODAY...AND
GIVEN THE WIND SPEEDS WILL ALREADY HAVE WIND CHILL ISSUES EARLY
THIS EVENING SO HAVE MOVED WARNING TIME FORWARD. TO THE
EAST...WARMER AIR IN THE TEENS WILL BE SLOW TO FALL THIS EVENING
BEFORE QUICKLY DROPPING OVERNIGHT AS WIND DIRECTIONS TURN
NORTHWESTERLY AND CLOUDS THIN. NAM PROJECTIONS OF WIND CHILLS HAVE
BEEN CONSISTENT AND OUR FORECAST ENDS UP FAIRLY CLOSE TO THOSE.
SOME AREAS IN AND NEAR THE TWIN CITIES MAY ACTUALLY NOT GET TO
ADVISORY CRITERIA...BUT THERE IS SOME UNCERTAINTY. AND JUST WITH
QUICKLY FALLING TEMPERATURES LATE TONIGHT DO NOT FEEL IT PRUDENT
TO CANCEL. EVENING SHIFT MAY BE ABLE TO BETTER REFINE AREA IF
NECESSARY.
WEDNESDAY LOOKS SUNNY BUT COLD AS THE SURFACE RIDGE AXIS MOVES
OVERHEAD. HAVE GONE BELOW MOST GUIDANCE FOR
TEMPERATURES...ESPECIALLY IN WESTERN AND SOUTHERN MN WHERE
READINGS MAY STAY BELOW ZERO. THE RETURN FLOW ON THE OTHER SIDE OF
THE HIGH DURING WEDNESDAY NIGHT WILL NOT BE A WARM ONE AT
FIRST...WITH WEST SOUTHWEST FLOW FROM THE HEART OF THE HIGH. THUS
WIND CHILLS WILL LIKELY REACH ADVISORY CRITERIA WEDNESDAY NIGHT
INTO THURSDAY MORNING OVER SOUTHERN MN AND POSSIBLY EASTERN MN AND
WESTERN WI.
UNSETTLED NORTHWEST FLOW WILL PREVAIL OVER THE AREA WITH NUMERICAL
MODELS HAVING NOTICEABLE SPREAD IN TIMING AND TRACK OF IMPULSES.
THERE IS CONSISTENCY THAT TEMPERATURES WILL GENERALLY RISE FROM
OVERNIGHT WEDNESDAY NIGHT ALL THE WAY THROUGH FRIDAY EVENING
/POSSIBLY JUST HOLDING STEADY THURSDAY NIGHT/. GFS AND SREF
ENSEMBLE PLUMES INDICATE THIS TREND WELL...AS WELL AS AROUND 80
PERCENT PROBABILITY OF THE TWIN CITIES REACHING 30 DEGREES FRIDAY
OR FRIDAY EVENING.
DEEP COLD AIR HAS BEEN ASSEMBLING IN CANADA FOR SOME TIME NOW WITH
500MB TEMPERATURES COMMONLY OF -35C TO -50C. THIS AIR MASS IS VERY
LIKELY TO FLOOD INTO THE REGION SOMETIME IN THE 5 TO 10 DAY
PERIOD...AND WITH TODAYS 12Z MODEL RUNS...THIS PLUNGE LOOKS
FOCUSED ON SOMETIME SUNDAY NIGHT THROUGH MONDAY NIGHT. BECAUSE OF
THE TEMPERATURE CHANGE AND FORECAST WINDS SPEEDS /A MODEL
CONSENSUS YIELDED SUSTAINED SPEEDS OF 20 KTS ALREADY IN WESTERN
AND SOUTHERN MN/...HAVE ALREADY INCLUDED MENTION IN THE HWO OF
POTENTIAL COLD...BLUSTERY...AND BLOWING SNOW DURING THAT TIME. THE
SYSTEM TO BRING IN SUCH AIR MAY ALSO HAVE ACCUMULATING SNOWFALL
ISSUES. SOMETHING TO KEEP AN EYE ON. CPC AND NAEFS PROBABILITIES
OF BELOW NORMAL TEMPERATURES NEXT WEEK ARE ALMOST DEFINITE.
&&
.AVIATION.../00Z TAF ISSUANCE/
A VERY QUIET FORECAST PERIOD AVIATION-WISE IS IN STORE ACROSS THE
AREA THROUGH WEDNESDAY. SOME MID AND HIGH CLOUDS ON THE NORTHWEST
SIDE OF THE MASSIVE STORM TO OUR SOUTHEAST WILL BE IN PLACE FOR
PART OF THE NIGHT... THEN CLEAR SKIES SHOULD PREDOMINATE THROUGH
THE REMAINDER OF THE FORECAST PERIOD. SOME GUSTINESS WILL STICK
AROUND INTO MID EVENING... PARTICULARLY OVER THE SOUTHEAST PORTION
OF THE AREA. OTHERWISE... WINDS DO NOT APPEAR TO BE A MAJOR ISSUE
THROUGH THE REMAINDER OF THE FORECAST WITH DIRECTION BACKING OVER
TIME AS THE LOW DEPARTS AND THE 1050MB ARCTIC HIGH DRIFTS SOUTHEAST.
KMSP... TAF REFLECTS FORECAST THINKING WITH MINIMAL UNCERTAINTY.
ONLY REAL POSSIBLE ISSUE IS IF ANY SCT SUB-5K FT AGL CLOUDS WORK
INTO THE AREA FOR A TIME THIS EVENING. OTHERWISE... VFR CONDITIONS
WILL PREVAIL THROUGH THE FORECAST.
