What happened

The episode as NWS EAX wrote it up.

A historic winter storm impacted a wide swath of the central and eastern United|States on Tuesday, February 1st into Wednesday, February 2nd. This was one of the|strongest blizzards ever to impact the region. Locally, cooperative and community|weather observers in Warrensburg, Clinton, Sedalia, Calhoun, Boonville, and|Brookfield, Missouri, each reported daily record snowfall totals near or exceeding 20|inches.

Nearby, an equally impressive snowfall of 12-18 inches fell along the Interstate 70|corridor, causing the first ever state-wide closure of Interstate 70, from Tuesday|night into early Wednesday. Snowfall rates of 2-3 inches per hour, also resulted in|the temporary closure of Kansas City International Airport, Tuesday afternoon and|evening. These snow rates also brought travel in the Kansas City metropolitan area|to a grinding halt, causing temporary closures of many of the urban expressways.|Some schools were closed for several days.

In addition to the heavy snow, this event also brought very rare blizzard conditions|to the region. Strong northwest winds frequently gusted between 35 and 45 mph|across the region, reducing visibilities to near zero at times in white out conditions,|and drifting snow 3 to 4 feet deep in many areas. Outside of the record snowfall of|central Missouri, significant snowfall also was observed across the bulk of western|and northeast Missouri, with 9-12 inches of snow falling across the Kansas City|metropolitan area. Amounts tapered off to 3 to 6 inches in the extreme northwest|corner of Missouri. However, blowing and drifting snow caused very hazardous driving|conditions in that area as well.

What forecasters said that day

...UPDATED AVIATION DISCUSSION...

...DANGEROUS AND LIFE THREATENING WINTER STORM ARRIVING TUESDAY
INTO WEDNESDAY...

.DISCUSSION...

SHORT TERM (TONIGHT-WED NIGHT)...

MOST CHANGES TODAY REMAIN MINOR AS WE'RE STILL IN A WAITING AND
MONITORING MODE FOR THE MAJOR IMPACTS OF THIS STORM EXPECTED TUESDAY
INTO WEDNESDAY. WV IMAGE THIS AFTN INDICATES THAT THE PRIMARY UPR LOW
IS CURRENTLY ROTATING THROUGH THE FOUR CORNERS REGION. A STRONG
INDICATION OF THE POTENCY OF THIS SYSTEM AND ITS UPR JET STRUCTURE
CAN BE SEEN WITH THE DEVELOPMENT OF WIDESPREAD CONVECTION AHEAD OF
THIS TROUGH IN NEW MEXICO AND ARIZONA.

LOCALLY...INVERTED TROUGH REMAINS SITUATED N-S ALONG THE KS/MO
BORDER. CONTINUAL LOW-LVL ISENTROPIC LIFT WILL CONTINUE TO PERCOLATE
LIGHT TO MODERATE FZDZ OR EVEN LIGHT FREEZING RAIN IN THE EASTERN
ZONES. COLDER AIR ALOFT IS NOW BEGINNING TO SETTLE INTO NORTHERN
MO...WHICH IS CONVERTING LIGHT PRECIP TO ICE PELLETS AND SNOW GRAINS.
THE INITIAL S/W WILL MOVE EAST OF THE CWA THIS EVENING...ALLOWING THE
INVERTED TROUGH TO EASE AND COLDER AIR TO MOVE IN FROM THE NW.
ISENTROPIC LIFT WILL ALSO BEGIN TO SHIFT OUT OF THE CWA THROUGH THE
NIGHT AND HAVE TRIED TO TAPER OFF POPS IN THE SOUTHERN CWA. FURTHER
NORTH...A TIGHTENING BAROCLINIC ZONE WILL LEAD TO ADDITIONAL LIGHT
SNOW DEVELOPMENT IN NORTHERN MO. DUE TO THE FINE NATURE OF THE
SNOW...EXPECTING OVERNIGHT ACCUMS LESS THAN AN INCH IN MOST
LOCATIONS.

FROM A MODEL PREFERENCE PERSPECTIVE...CONTINUE TO USE A BLEND OF THE
ENSEMBLES AND THEIR PLUMES WITH SOME GUIDANCE BY THE 12Z GFS. WHILE
IT MAY BE HELPFUL...FEEL THE HIGHER RESOLUTION NAM GUIDANCE IS
THROWING TOO MUCH CONVECTIVE INFLUENCE INTO ITS SOLNS TO BE OF USE.
THE GEM/EC REMAIN TROUBLING THOUGH WITH SUCH OVERDEVELOPED UPR JET
COUPLETS THAT THEY PULL THE UPR WAVE FURTHER NW AND DEVELOP AN
INCREDIBLE DEFORMATION SNOW BAND AND TROWAL WELL INTO NWRN MO. WHILE
THIS IS FEASIBLE...NOT A TON OF SUPPORT FROM ENSEMBLES.
HOWEVER...WILL LEAVE THE DOOR OPEN AND TREND QPF A BIT IN THAT
DIRECTION.

ONE OF THE STRONGEST AND HIGHEST IMPACT STORMS OF RECENT HISTORY WILL
BEGIN TO MOVE INTO AND THROUGH THE REGION TOMORROW. BY THE EARLY
MORNING HOURS...WIDESPREAD CONVECTIVE DEVELOPMENT WILL OCCUR OVER THE
SOUTHERN PLAINS. THROUGH THE MORNING...STRONG PVA COMBINED WITH THE
INTENSE DEVELOPMENT OF A COUPLED JET STRUCTURE WILL ALLOW AN
EXPANSIVE AREA OF SNOW TO DEVELOP IN OKLAHOMA...KANSAS AND MISSOURI.
THIS AREA WILL RAPIDLY EXPAND NE TUESDAY MORNING. NUMEROUS SIGNALS
EXIST AS TO THE POTENTIAL FOR CONVECTIVE SNOW FALL ACROSS THE
SOUTHEASTERN CWA...AND WILL EXPAND TSRA MENTION FOR MUCH OF TUESDAY.
SNOWFALL RATES COULD EXCEED 2-4" PER HOUR AT TIMES.

THIS RAPIDLY INTENSIFYING UPR CYCLONE WILL CONTINUE TO DEVELOP AS IT
CROSSES CENTRAL MO...PEAKING IN INTENSITY AS ARRIVES IN NE ILLINOIS.
AS I'VE SAID IN PREVIOUS DISCUSSIONS...THE AMOUNT OF MOISTURE
ADVECTION IN THIS SYSTEM IS TRULY AMAZING WITH LITTLE TO NO MODEL
ADJUSTMENT FROM THE 60-70 KNOT LLJ FEEDING THIS SYSTEM.

BY WED EVE A LARGE TROWAL WILL HAVE FORMED WITH WARM AIR STREAMING
WELL AROUND THE UPR LOW. THIS WILL POTENTIALLY KEEP VERY HEAVY SNOW
IN NORTHEASTERN PORTIONS OF THE CWA THROUGH THE NIGHT.

AN UNBELIEVABLE AMOUNT OF COLD AIR WILL DRAIN DOWN THE FRONT RANGE IN
THE WAKE OF THIS SYSTEM. FEEL HIGHS ON WEDNESDAY WILL ONLY REACH THE
SINGLE DIGITS TO LOWER TEENS IN THE SE. LOWS WEDNESDAY NIGHT HAVE
FULL POTENTIAL TO FALL BELOW ZERO. A LIGHT 5 TO 10 KNOT SFC WIND MAY
LEAD TO WIDESPREAD ADVISORY WIND CHILLS AND THE POTENTIAL FOR ONE OF
THE FIRST WIND CHILL WARNINGS IN MANY YEARS IN THE NORTHERN CWA.

HAZARDS:

THE MOST DANGEROUS ASPECT OF THIS STORM SYSTEM WILL COME IN THE FORM
OF ITS VERY HIGH SLR AND DEVELOPMENT OF STRONG PGF WINDS TUESDAY AND
TUESDAY NIGHT. HAVE FOLLOWED SEVERAL TOOLS FOR FORECASTING BLIZZARDS
TODAY...AND THE OVERWHELMING SUGGESTION IS THAT BLIZZARD OR NEAR
BLIZZARD CRITERIA MAY BE MET OVER A LARGE PORTION OF THE CWA TUE AND
TUE NIGHT. WITH A 1050 HIGH IN THE WESTERN PLAINS AND THE DEVELOPING
OF A 993 MB LOW IN THE MO BOOTHEEL THE RESULTANT SFC PRESSURE
GRADIENT WILL APPROACH 50 TO AS MUCH AS 70 MICROBARS/KM BY TUE EVE.
WHATS EVEN MORE CONCERNING IS THE SUGGESTION OF A CHANNEL OF 50-55
KNOT WINDS AT THE 850MB LVL ON THE BACKSIDE OF THE DEVELOPING UPR
LOW. GIVEN POTENTIAL SFC-850 LAPSE RATES APPROACHING 7 TO 8 C/KM PER
ADJUSTED NAM/GFS GUIDANCE FEEL MIX DOWN POTENTIAL IS ELEVATED TO
HIGH. THUS...WILL BE ISSUING A FAIRLY WIDESPREAD BLIZZARD WARNING FOR
TUESDAY AND TUESDAY NIGHT. WINDS THIS STRONG REGARDLESS OF THE AMOUNT
OF SNOW WILL BE LIFE THREATENING...AND WILL LEAD TO SEVERE DRIFTING
OF HEAVY SNOW.

THE NORTHWEST CORNER IS THE TRICKIEST ASPECT OF THE FCST. FEEL THAT
BLIZZARD CONDITIONS MAY ALSO BE EXPERIENCED IN THESE
AREAS. HOWEVER...LOWER THAN NORMAL CONFIDENCE LEADS ME TO DEFER TO
THE NEXT SERIES OF MODEL RUNS.

ACCUMULATIONS:

THIS POTENTIALLY HISTORIC STORM HAS THE POTENTIAL FOR WIDESPREAD FOOT
OR MORE SNOWS...ESPECIALLY IN AREAS EAST OF THE INTERSTATE 35
CORRIDOR. MODELS AND ENSEMBLES SUGGEST THE HEAVIEST CORRIDOR FROM
NEVADA TO COLUMBIA AND INTO THE NERN CORNER OF MO...WHERE I WOULDN'T
BE SHOCKED TO SEE TOTALS APPROACH 20 INCHES OR MORE. FURTHER WEST AND
NORTHWEST THE GRADIENT WILL RELAX...BUT VERY SIGNIFICANT SNOW TOTALS
UP TO 10 INCHES WILL BE LIKELY.

DUX

MEDIUM RANGE (THURSDAY THROUGH MONDAY)...

MID-RANGE MODELS FOR THE TAIL END OF THE WORK WEEK CONTINUE TO AGREE
NOMINALLY THAT THE COLD AIR...THAT WILL BE FOLLOWING THE EARLY WORK
WEEK STORM SYSTEM...WILL STILL BE IN PLACE THROUGH THURSDAY...BUT
WILL BEGIN TO GET SHOVED EAST BY FRIDAY AS A CLIPPER SYSTEM DROPS
INTO THE NORTHERN AND CENTRAL PLAINS. THIS SHOULD ALLOW SOME
SLIGHTLY WARMER AIR TO MOVE BACK INTO MISSOURI STARTING FRIDAY AND
FOR THE WEEKEND. TEMPERATURES FOR THE WEEKEND MIGHT BE ABLE TO POKE
ABOVE THE FREEZING MARK...BUT THAT WILL BE HIGHLY DEPENDENT ON THE
AMOUNT OF SNOW IN PLACE ACROSS THE REGION...AND HOW THAT MODIFIES
THE AIRMASS ABOVE IT. OTHERWISE...WITH THE ARCTIC AIR STILL IN PLACE
THROUGH THURSDAY...EXPECT WIND CHILL VALUES COULD RANGE AS LOW AS
-20 TO -25 DEGREES FAHRENHEIT DURING THE MORNING HOURS.

THE CLIPPER SYSTEM FOR FRIDAY MIGHT NOT HAVE MUCH TO WORK WITH IN THE
WAKE OF THE EARLY WORK WEEK SNOW STORM. HOWEVER...INTERACTIONS
BETWEEN A GULF COAST SHORTWAVE AND THE CLIPPER SYSTEM MIGHT BE ABLE
TO GENERATE ENOUGH LIFT TO SQUEEZE SOME LIGHT SNOW OUT OF THE LIMITED
MOISTURE AVAILABLE. SO...WITH ONLY LOW CONFIDENCE AT THIS TIME...HAVE
OPTED TO ONLY INCLUDE SLIGHT CHANCE POPS FOR FRIDAY NIGHT. LOOKING
TOWARDS THE END OF THE WEEKEND...ANOTHER CLIPPER SYSTEM IS EXPECTED
TO DROP INTO THE NORTHERN PLAINS. AGREEMENT AMONGST THE MODELS IS
MORE CONTENTIOUS IN THIS OUTER PERIOD...BUT IS SUFFICIENT TO WARRANT
SOME CHANCE POPS FOR SNOW SUNDAY NIGHT.

CUTTER

&&

.AVIATION...

INVERTED TROUGH HAS PIVOTED JUST EAST OF THE TERMINALS OVER THE PAST
FEW HOURS...ALLOWING WINDS TO SHIFT INTO THE NORTHWEST RESULTING IN
A NOMINAL IMPROVEMENT IN CEILING/VISIBILITY. MVFR VISIBILITIES AND
IFR CEILINGS WILL STILL CONTINUE OVERNIGHT WITH SPOTTY FREEZING
DRIZZLE/SNOW GRAINS...WHICH SHOULD HAVE LITTLE ADDITIONAL IMPACT.

RAPIDLY DEEPENING CYCLONE WILL BEGIN TO REACH ITS CLOSEST POINT OF
APPROACH TOMORROW MORNING WHILE AN EQUALLY STRONG ARCTIC HIGH
SETTLES INTO EASTERN MONTANA. BETWEEN THESE TWO...NORTH WINDS WILL
ACCELERATE QUICKLY DURING THE MORNING WHILE SNOW BEGINS TO
OVERSPREAD THE AREA FROM THE SOUTH. SNOW WILL BE HEAVY AT
TIMES...ESPECIALLY AT THE KANSAS CITY TERMINALS...WITH BLIZZARD
CONDITIONS EXPECTED FOR MUCH OF THE AFTERNOON. EXPECT THAT ALL
AVIATION TRAFFIC WILL BE HALTED AT THE KANSAS CITY TERMINALS AND
SURROUNDING EXECUTIVE/GENERAL AVIATION TERMINALS (IXD/OJC/LXT/RCM).
ONLY SLIGHTLY BETTER CONDITIONS EXPECTED UP AT ST. JOSEPH. SNOWFALL
WILL GRADUALLY DIMINISH IN INTENSITY BY MID EVENING...BUT STRONG
NORTHWEST WINDS AND BLOWING SNOW WILL MAINTAIN GROUND PROBLEMS WELL
PAST THE END OF THE TAF CYCLE.

...HISTORIC AND POTENTIALLY LIFE-THREATENING WINTER STORM TO IMPACT
THE AREA TUESDAY AND WEDNESDAY...

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHWEST...NORTH CENTRAL AND
WEST CENTRAL MISSOURI...AS WELL AS EXTREME EASTERN KANSAS.

.DAY ONE...TONIGHT.

 THE RISK OF HAZARDOUS WEATHER IS ELEVATED.

 WEATHER HAZARDS EXPECTED:
 FREEZING DRIZZLE
 LIGHT SNOW

 DISCUSSION:

 LIGHT FREEZING DRIZZLE WILL CONTINUE TO PRODUCE A THIN GLAZE OF
 ACCUMULATION THROUGH EARLY THIS EVENING. ALTHOUGH ROAD IMPACTS HAVE
 BEEN MAINLY FELT ACROSS FAR NORTHERN AND NORTHWESTERN MISSOURI
 TODAY...WET ROADWAYS ELSEWHERE WILL BECOME SLICK AND HAZARDOUS
 OVERNIGHT AS TEMPERATURES SLOWLY FALL THROUGH THE 20S.

 OTHERWISE...THE DRIZZLE WILL BEGIN TO MIX OR CHANGEOVER TO A VERY
 FINE LIGHT SNOW TONIGHT. EXTREME NORTHWEST MISSOURI MAY RECEIVE AN
 INCH OR TWO ACCUMULATION WITH LITTLE OR NO IMPACTS ELSEWHERE.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

 A POTENTIALLY LIFE THREATENING WINTER STORM WILL IMPACT A LARGE
 PORTION OF THE REGION INTO THE GREAT LAKES ON TUESDAY AND
 TUESDAY NIGHT...BRINGING GROUND AND AVIATION TRAVEL TO A HALT OVER
 A LARGE AREA. SNOW...HEAVY AT TIMES WILL SPREAD NORTH TO THE I-70
 CORRIDOR BEFORE NOON...AND CONTINUE THROUGH TUESDAY NIGHT.

 FOR AREAS WEST OF INTERSTATE 35...TOTAL SNOWFALL AMOUNTS WILL
 AVERAGE BETWEEN 6 INCHES IN EXTREME NORTHWEST MISSOURI TO 9 TO 11
 INCHES ALONG THE I-35 CORRIDOR. WINDS OF 20 TO 30 MPH WILL RESULT
 IN BLOWING SNOW AND AREAS OF REDUCED VISIBILITY.

 FOR AREAS ALONG AND EAST OF INTERSTATE 35...A WIDESPREAD SWATH OF
 12 TO 16 INCHES OF SNOW IS EXPECTED WITH THE POTENTIAL FOR HISTORIC
 SNOW TOTALS OF 20 OR MORE INCHES ACROSS PORTIONS OF CENTRAL
 MISSOURI...WITH DRIFTS SEVERAL FEET DEEP POSSIBLE. IN ADDITION TO
 THE VERY HEAVY SNOW...STRONG NORTHERLY WINDS OF 25 TO 30 MPH WITH
 GUSTS TO NEAR 40 MPH WILL BRING BLIZZARD CONDITIONS THROUGH MUCH OF
 THE AFTERNOON AND EVENING HOURS. WHITEOUT CONDITIONS WITH
 SIGNIFICANT BLOWING AND DRIFTING SNOW WILL MAKE ANY TRAVEL
 POTENTIALLY LIFE THREATENING. POWER OUTAGES MAY ALSO BE POSSIBLE.

 IN THE WAKE OF THIS SNOW STORM...AN ARCTIC AIR MASS WILL OVERSPREAD
 THE REGION...SENDING TEMPERATURES WELL BELOW ZERO BY MIDWEEK...
 ALONG WITH DANGEROUSLY COLD WIND CHILLS. GIVEN THE LASTING IMPACTS
 OF THE WINTER STORM...PERSONS SHOULD MAKE SURE THEY HAVE AN
 ADEQUATE SUPPLY OF FOOD AND MEDICATION...AS WELL AS AN ALTERNATE
 HEAT SOURCE SHOULD ELECTRICAL POWER BECOME UNAVAILABLE.
