A low pressure system tracking from Minnesota into Ontario produced moderate snow over much of Upper Michigan from the 18th into the early morning hours of the 19th. Gusty northwest winds behind the low brought in much colder air and generated a prolonged period of moderate to heavy lake effect snow in the northwest wind snow belts of west and north central Upper Michigan into the 21st.

Gusty northwest winds behind the low brought in much colder air and generated a prolonged period of moderate to heavy lake effect snow in the northwest wind snow belts of west and north central Upper Michigan into the 21st.

733 AM EDT MON MAR 18 2013
.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 551 AM EDT MON MAR 18 2013
WATER VAPOR IMAGERY AND RUC ANALYSIS SHOW A VIGOROUS LOOKING
SHORTWAVE TROF MOVING ACROSS THE NRN PLAINS TOWARD THE UPPER
MISSISSIPPI VALLEY. BAND OF SNOW HAS BEEN SLOWLY ORGANIZING DURING
THE NIGHT ACROSS MN AHEAD OF FEATURE. FRONTAL BOUNDARY DRAPPED
ACROSS THE OHIO/TENNESSEE VALLEYS IS EFFECTIVELY PREVENTING A GOOD
SURGE OF MOISTURE N TO THE UPPER LAKES AHEAD OF WAVE. PER 00Z
RAOBS...PRECIPITABLE WATER VALUES UPWARDS OF 1 INCH ARE SOUTH OF
THE BOUNDARY WHILE VALUES ARE ONE-QUARTER TO ONE-HALF INCH OVER THE
NRN PLAINS...JUST A LITTLE ABOVE NORMAL FOR THIS TIME OF YEAR. THIS
WILL WORK TO KEEP SNOW ACCUMULATIONS IN CHECK DESPITE VIGOROUS
DYNAMICS ASSOCIATED WITH SHORTWAVE BECOMING INCREASINGLY NEGATIVELY
TILTED AS IT MOVES ACROSS THE WRN GREAT LAKES LATE THIS
AFTN/TONIGHT.
OVERALL...FCST FOR TODAY/TONIGHT WAS IN GOOD SHAPE...SO NO MAJOR
ADJUSTMENTS WERE MADE. SLOWED TIMING OF SNOW JUST A BIT BASED ON
OVERNIGHT RADAR TRENDS AND MODEL TRENDS. MODEL CONSENSUS PCPN
AMOUNTS ARE ROUGHLY 0.2 TO 0.4 INCHES. WITH SNOW RATIOS LIKELY
AROUND 15 TO 1...ADVY FOR GENERAL SNOWFALL OF 3 TO 6 INCHES LOOKS ON
TRACK. MOST LOCATIONS WILL PROBABLY BE IN THE 3-4 INCH RANGE...AND
THE SNOW MAY FALL AT DECENT RATE FOR A WHILE.
SNOW WILL DIMINISH TO PATCHY -SN W TO E TONIGHT AS BAND OF SNOW TIED
TO STRONG FORCING AHEAD OF SHORTWAVE DEPARTS. ATTENTION OVERNIGHT
THEN TURNS TO THE W WHERE STRONG NW WINDS WILL DEVELOP IN THE WAKE
OF SFC LOW MOVING ACROSS LAKE SUPERIOR. WHILE THERE IS SOME
UNCERTAINTY IN TIMING THE ARRIVAL OF THE STRONG NW WINDS...WHICH
WILL ARRIVE OVER GOGEBIC/ONTONAGON COUNTIES BEFORE THE
KEWEENAW...DEEP MOISTURE/CONVERGENT CYCLONIC FLOW AND A DEEP DGZ
SUGGEST VERY HVY LAKE ENHANCED SNOW WILL LIKELY DEVELOP FROM KIWD N
THRU THE KEWEENAW BY DAYBREAK. COULD EASILY SEE SNOWFALL RATES OF
1-3IN/HR INTO TUE MORNING ACROSS THE HIGHER TERRAIN OF THE W. BLSN
WILL ALSO BECOME AN INCREASING HAZARD AS NW WINDS WILL GUST OVER
30MPH TO AS HIGH AS 40MPH...ESPECIALLY IN OPEN AREAS NEAR LAKE
SUPERIOR. WHITE-OUTS WILL BE A GOOD POSSIBILITY DUE TO COMBINATION
OF HVY SNOW/BLSN.
.LONG TERM...(TUESDAY THROUGH SUNDAY)
ISSUED AT 551 AM EDT MON MAR 18 2013
MODELS AGREE THAT STRONG SHORTWAVE MOVING THROUGH THE REGION TODAY
HELPS TO ESTABLISH LOW-MID LEVEL TROUGHING THROUGH THE WEEK. ONCE
SFC-H85 LOWS PUSH EAST OF LK SUPERIOR...EXPECT COLD AIR TO POUR
ACROSS THE ENTIRE GREAT LAKES REGION. SINCE THE TROUGH IS NEARLY
STATIONARY A LOT OF MOISTURE THROUGH H7 PERSISTS ACROSS THE REGION
THROUGH AT LEAST WEDNESDAY. ENOUGH COLD AIR IN BLYR TO SUPPORT AT
LEAST MODERATE LK EFFECT SNOWS THROUGH MIDWEEK BEFORE CONDITIONS
BECOME MORE MARGINAL BY LATE WEEK AS MOISTURE ABOVE H9 DIMINISHES
AND LOW-LEVEL FLOW BECOMES NOT AS CYCLONIC. PROLONGED PERIOD OF
MODERATE LK EFFECT SNOWS EXPECTED WITH POTENTIAL HEAVY LK EFFECT AT
TIMES THROUGH WEDNESDAY GIVEN DEEP MOISTURE IN PLACE...STRONGEST
LOW-LEVEL CONVERGENCE AND GREATEST INSTABILITY WITH DELTA T/S OVER
15C AND LAKE EQL TOWARD 10KFT. SOUNDINGS ALSO SHOW MAJORITY OF LAKE
CONVECTIVE LAYER WITHIN THE DGZ WHICH HELPS BOOST SLR/S OVER 20:1.
OTHER FACTOR TUESDAY/TUESDAY NIGHT AND INTO WEDNESDAY MORNING WILL
BE STRONG WINDS WITH OVER 30 KTS LOCATED WITHIN THE BLYR. GUSTS OVER
35KT/40 MPH SEEM POSSIBLE IN THE MOST VIGOROUS LK EFFECT CONVECTION.
BLOWING SNOW WILL INCREASE BY LATER TUESDAY AFTN IN AREAS FAVORED BY
NW WINDS AND THIS HAZARD WILL CONTINUE THROUGH MUCH OF WEDNESDAY.
A COUPLE MAIN ISSUES TO SORT OUT AND THESE ARE NOT TRIVIAL AS THEY
IMPACTED HEADLINE DECISIONS THIS MORNING. MAIN ISSUE THROUGH TUESDAY
IS THERE APPEARS TO BE A BREAK BTWN THE SYNOPTIC SNOW THAT MOVES
THROUGH THIS AFTN/TONIGHT AND INCREASING LK ENHANCED SNOW OVER EAST
ON TUESDAY AFTN. LOCAL WRF AND REGIONAL GEM AGRESSIVE IN DEVELOPING
SFC TROUGH OVER EASTERN CWA ON TUESDAY MORNING TO THE SOUTH OF
PRIMARY SFC LOW OVER EASTERN LK SUPERIOR. COARSER GFS HINTS AT THIS
IDEA AS WELL. WINDS AHEAD OF TROUGH BACK SW SO THAT LK EFFECT ISSUES
PROBABLY WILL NOT DEVELOP OVER THE FAR EAST UNTIL AFTER 18Z ON
TUESDAY. ONCE TROUGH SHIFTS THROUGH...LK EFFECT COULD BECOME QUITE
INTENSE JUST IN WAKE OF TROUGH AS CONVERGENCE RAMPS UP AND COLD AIR
ARRIVES LEADING TO QUICKLY INCREASING OVER-WATER INSTABILITY. GIVEN
CERTAIN BLSN HAZARD ALONG WITH HEAVIER LK ENHANCED SNOWFALL...A
WARNING MAY EVENTUALLY BE NEEDED. SINCE THERE WILL BE ENOUGH OF A
GAP BTWN THE SYNOPTIC SNOW AND HEAVIER LK ENHANCED SNOW LATER
TUESDAY DECIDED IN FAVOR OF WINTER STORM WATCH FOR EASTERN CWA NEAR
LK SUPERIOR 12Z TUESDAY THROUGH 12Z THURSDAY. DID NOT GET TOO
SPECIFIC WITH TIMING SINCE SOME MODELS DO SHOW QUICKER ONSET OF LK
ENHANCED SNOW THAN GEM-REGIONAL AND LOCAL-WRF...ESPECIALLY IN THE
MUNISING AND GRAND MARAIS AREAS. WESTERN TIER OF CWA IS MORE CLEAR
CUT. MAIN ISSUE OVER THE WEST IS HOW LONG TO RUN THE WARNING. KEPT
IT PRETTY SIMPLE AT THIS POINT AND KEPT WARNING IN PLACE UNTIL WINDS
IN BLYR BEGIN TO DECREASE BLO 25 KTS AND WHEN DEEPER MOISTURE STARTS
TO CUT OUT. ON BOTH ACCOUNTS IT APPEARS SUITABLE CUTOFF WAS DAYBREAK
ON THURSDAY MORNING. MORE LK EFFECT CONTINUES ON THURSDAY...BUT
SHOULD BE BEGINNING TO SHOW DIMINISHING TREND COMPARED TO MORE
FAVORABLE SETUP IN PLACE TUESDAY AND WEDNESDAY.
LK EFFECT DIMINISHES FURTHER INTO FRIDAY BUT PROBABLY WILL NOT GO
AWAY COMPLETELY AS LIGHT WIND PERSISTS OFF LK SUPERIOR. THOUGH H85
TEMPS ARE WARMING...COOL ENOUGH BENEATH LOWERING INVERSION TO HAVE
SOME LGT SNOW SHOWERS/FLURRIES. NO SIGNIFICANT WX INTO THE WEEKEND
BUT NOT ALL THAT WARM EITHER AS GENERAL TROUGHING CONTINUES. SINCE
MOST OF FOCUS WAS ON SNOW/BLSN AND HEADLINES...USED MODEL CONSENSUS
FOR THE FORECAST BEYOND THURSDAY.

LOW PRES APPROACHING FROM THE W WILL PUSH A BAND OF SNOW ACROSS
UPPER MI TODAY. WITHIN AN HR OR TWO OF THE ONSET OF SNOW...EXPECT
CONDITIONS TO FALL TO IFR. SNOW SHOULD BEGIN AT KIWD MID TO LATE
MORNING...AT KCMX EARLY THIS AFTN AND AT KSAW MID TO LATE AFTN.
PRIOR TO THE ARRIVAL OF THE SNOW...UPSLOPE SSE WINDS OFF LAKE
MICHIGAN WILL LIKELY RESULT IN LOW MVFR CIGS DEVELOPING AT KSAW
AROUND MID MORNING. SNOW SHOULD DIMINISH FOR A WHILE TONIGHT AND MAY
ALLOW CONDITIONS TO IMPROVE TO MVFR. THAT'S MOST LIKELY TO HAPPEN AT
KSAW. LATE TONIGHT...STRONG NW WINDS BEHIND THE LOW WILL BRING
MDT/HVY LAKE ENHANCED SNOW TO KIWD/KCMX WITH CONDITIONS LIKELY
FALLING TO LIFR.
