341 PM EST SAT FEB 3 2007

...DANGEROUS WINTER CONDITIONS WILL OCCUR THROUGH TUESDAY AFTERNOON...

.EXTREMELY COLD AIR WILL POUR INTO THE SOUTHERN GREAT LAKES
REGION INTO EARLY NEXT WEEK. STRONG WINDS WILL COMBINE WITH THE
FRIGID TEMPERATURES TO PRODUCE POTENTIALLY LIFE THREATENING WIND
CHILL VALUES. MUCH OF FAR SOUTHERN LOWER MICHIGAN WILL SEE SIGNIFICANT
BLOWING AND DRIFTING SNOW CONTINUE INTO THIS EVENING...WITH WINDS
SLOWLY DIMINISHING AND SNOW SHOWER ACTIVITY BECOMING MORE
SCATTERED AND LIGHT IN NATURE. 

THIS IS A VERY DANGEROUS SITUATION. PEOPLE NEED TO STAY INDOORS
AND RESTRICT UNNECESSARY TRAVEL. EXPOSED FLESH WILL EXPERIENCE
FROSTBITE IN A VERY SHORT PERIOD OF TIME. BLOWING SNOW WILL CAUSE
WHITE OUT CONDITIONS AND SIGNIFICANT DRIFTING SNOW WILL MAKE
TRAVEL ON NORTH SOUTH ROADS NEARLY IMPOSSIBLE.

.AVIATION...
LITTLE CHANGES TO GOING TAFS. SLOWED TIMING WITH HIGHEST AND MORE
VEERED WINDS PER CURRENT ANALYSIS WITH HEART OF STRONG ISSALLOBARIC
COUPLET JUST INTO NRN IL AT 12 UTC. ABRUPT DETERIORATION OF FLIGHT
CONDITIONS LATER TODAY STILL EXPECTED. LR STEEPEN AS 800-700MB LAYER
DRASTICALLY COOLS BECOMING SUFFICIENTLY STEEP TO AFFORD UP TO L2
MOMENTUM XFER. WITH SYNOPTIC MOISTURE BEING WROUGHT OUT LIGHT SNOW
TO INCREASE AND BRING CONDITIONS IN SN/BS TO AT LEAST IFR AT KFWA
AND WITH SOME LAKE ENHANCEMENT ALBEIT THE DENDRITIC GROWTH LAYER TO
BECOME NULL/VOID AS DEPTH OF COLD AIRMASS INCREASES LATER IN THE
AFTERNOON. WITH HEAVY SNOWPACK NEAR KSBN AND LITTLE TO SHIELD
UPSTREAM 270-280 WIND LOCALLY AT AIRPORT WILL BRING CONDITIONS THERE
TO LIFR WITH FAIRLY HIGH CONFIDENCE. INDICATED IMPROVING CONDITIONS
LATER TONIGHT WITH DECREASING WIND SPEED AS MID LVL ENERGY
TRANSLATES INTO NEWFOUNDLAND WITH RESULTANT SFC REFLECTION GRADIENT
STRETCHING.

&&

.SHORT TERM...
TODAY AND TONIGHT. EXTREME CHANGES IMMINENT. EXTREME AND SLOWLY
INCREASING 7MB/3HR FALL-RISE COUPLET IMMEDIATELY WEST ASSOCIATED
WITH LEADING EDGE ARCTIC FRONT INTO NRN IL AT 10 UTC. G30 KTS INTO
ERN IA/NRN MO ALREADY. AND AS 900-800MB LAYER COOLS DRAMATICALLY
LATER THIS AM...WITH LAPSE RATES TO GT 8 C/KM 950-800 LAYER MOMENTUM
XFER TO NEAR LEVEL 2 POSSIBLE AND WITH SNOW OBSERVER REPORTS AND
NOHRSC SNOW DEPTH MAP...A HUGE BLOWING/DRIFTING MESS FORESEEN BY
MIDDAY IN FAR NW CWA. HAVE GONE WITH STRONGLY WORDED WS WARNING...AS
2-5 INCHES OF POWDERY FRESH SNOW THIS AM HAS REMAINED LARGELY JUST
NORTH OF CWA AND STRONGEST WINDS PER NAM12 00/06 UTC PEGGED JUST
NORTH OF CWA. LAPS SOUNDINGS SHOW STRONG INVERSION BASED AT 950MB
AND QUESTION WARMING POTENTIAL THIS MORNING PRIOR TO COLDEST AIR OF
SEASON INFILTRATING AND HAVE LOWERED MAX T TODAY AND ADDED DETAIL OF
A NON-DIURNAL THERMOGRAPHIC CURVE. UPPED POPS FURTHER TODAY THOUGH
CONCEDE OUTSIDE OF LES REGION AMOUNTS TO BE MINUSCULE AND NEAR
IMPOSSIBLE TO MEASURE WITH BLSN. LOW LEVELS TO SATURATE WITH SUCH
STRONG COOLING IMMEDIATELY BEHIND FROPA AND ANTICIPATE CLOUD/RADAR
COVERAGE TO CONTINUE TO INCREASE THROUGH THE DAY. ANY CHANCE FOR
DENDRITIC GROWTH THEN SHUTS DOWN IN THE AFTERNOON AS M13-M18C LAYER
DROPS SUB-CLOUD BASE. GRADUAL IMPROVEMENT WITH RESPECT TO SN/BLSN
LATE TONIGHT...HOWEVER WIND CHILL BECOMES DOMINANT HAZARD AS CORE OF
COLDEST 1000-850MB LAYER AVG TEMPERATURES OF M22-M23C SETTLE INTO
CWA AND CORE OF ASSOCIATED ARCTIC SFC HIGH STILL IN FAR NRN SASK.

&&

.LONG TERM...
THE NORTHERN PART OF THE CWA SUNDAY HAS A CHANCE FOR SOME
LAKE EFFECT SNOW...ESPECIALLY IN THE NORTHWESTERN PART. THE FLOW
OF THE WIND WILL BE FROM JUST SOUTH OF WEST TO THE WEST WITH GOOD
LIFT/OMEGA BEING GENERATED BY THE LAKE...AND GOOD MOISTURE IN THE
LOWER LEVELS. 850MB DELTA T VALUES FOR SUNDAY ARE GOING TO BE
AROUND 30. THIS WILL CONTINUE INTO SUNDAY NIGHT BUT THE TRACK OF
THE SNOW IS EXPECTED TO SHIFT. THE WIND WILL TURN TO THE NORTHWEST
WHICH WILL CREATE A LONGER FETCH ACROSS LAKE MICHIGAN...WHICH
SHOULD BE ABLE TO GENERATE MORE LONGER BANDS OF SNOW. 850MB DELTA
T VALUES ARE GOING TO STILL BE VERY HIGH WITH LOW LEVEL MOISTURE
AND OMEGA/LIFT. SO INCREASED SNOW CHANCES IN THE NORTH FURTHER
EASTWARD FROM LAKE MICHIGAN. THE WIND STAYS OUT OF THE NORTHWEST
ON MONDAY BUT 925MB OMEGA LOOKS TO DECREASE AS MONDAY WEARS ON.
THEREFORE HAVE THE HIGHER CHANCES FOR THE SNOW PULLED BACK SOME
TOWARDS LAKE MICHIGAN...THE SAME WITH THE QPF. TEMPERATURES ARE
GOING TO BE QUITE COLD SUNDAY AND MONDAY AND THE GOOD SNOW GROWTH
TEMP RANGE WILL BE QUITE CLOSE TO THE GROUND AND NOT NECESSARILY
IN THE THICKEST PART OF THE MOISTURE PROFILE. SO DO NOT HAVE TOO
MUCH QPF IN THE FORECAST RIGHT NOW. NO CHANGES WERE MADE FOR NEXT
WEEK WITH THE GFS CHANGING QUITE A BIT AND MODELS NOT IN THE BEST
OF AGREEMENTS.
