745 PM EDT SUN APR 19 2009
UPDATED FOR 00Z TAF ISSUANCE
.UPDATE...
A CALL TO A SPOTTER AT AHMEEK IN KEWEENAW COUNTY CONFIRMED THE FZRA
REPORTED ON THE CMX OB DURING THE LAST COUPLE OF HRS. OPTED TO ISSUE
WINTER WX ADVY FOR KEWEENAW COUNTY AND BEGIN GOING HEADLINE FOR
NORTHERN HOUGHTON COUNTY TO NOW TO ACCOUNT FOR THIS FZRA...
ESPECIALLY WITH AREA OF HIER RADAR RETURNS NOTED JUST S OF CMX AND
MOVING SLOWLY N. LATEST RUC AND NAM FCST SDNGS FOR CMX DO SHOW A
WARM LYR ARND H85...BUT WITH SFC TEMPS ABV 32 AS WELL. WITH ARRIVAL
OF SHARPER DPVA/HGT FALLS/DEEP LYR H85-3 QVECTOR CNVGC IN THE
DIFFLUENT UPR FLOW IN ADVANCE OF WELL DEFINED SHRTWV MOVING THRU NRN
MN...THINK THE RUC/NAM FCST SDNGS SHOWING THE ELEVATED WARM LYR
COOLING ENUF THRU THIS EVNG TO CHG ANY FRZG PCPN TO SN IS ON TRACK.
SO MENTIONED FZRA IN THE GRIDS UNTIL ONLY 03Z. ATLHOUGH CURRENT FCST
SN AMTS IN KEWEENAW COUNTY THRU TUE ARE NOT AS GREAT AS IN HOUGHTON
COUNTY...OPTED TO EXTEND THE KEWEENAW COUNTY ADVY THRU TUE AS WELL
TO ACCOUNT FOR UP TO 9 INCHES OF WET SNOW DURING THAT EXTENDED PD.
&&
.SHORT TERM (TONIGHT AND MONDAY)...
A WETTING RAIN TODAY WILL LAY THE GROUND WORK FOR ADDITIONAL
PRECIPITATION OVERNIGHT. ON THE PLUS SIDE...WITH WARMER THAN NORMAL
TEMPERATURES OF LATE AND PLENTY OF CLOUD COVER...GROUND TEMPERATURES
WILL REMAIN ABOVE FREEZING ACROSS MOST OF THE CWA. THIS WILL LIMIT
ANY ICING OF ROADWAYS OVERNIGHT INTO MONDAY AND KEEP SNOW AMOUNTS TO
A MINIMUM...UNTIL MODERATE TO HEAVY SNOW DEVELOPS AND OVERCOMES THE
WARM GROUND TEMPERATURES.
A SIMILAR...BUT SLIGHTLY MORE WESTWARD PATTERN LOOKS TO BE IN THE
WORKS OVERNIGHT AND MONDAY. THE SFC HIGH PRESSURE SYSTEM OVER JAMES
BAY WILL CONTINUE TO LOSE CONTROL OF FAR EASTERN UPPER MICHIGAN AND
LS OVERNIGHT...AS IT SLIPS TO SE QUEBEC. CLOUDS AND DZ HAVE BEEN
ABLE TO SLIDE ACROSS THE ENTIRE CWA.
LOOK FOR THE WEAK SFC LOW OVER CENTRAL AND EASTERN NORTH DAKOTA THIS
AFTERNOON TO JOIN FORCES WITH THE DEEPENING MAIN LOW OVER THE MID
MISSISSIPPI AND LOWER OHIO VALLEYS LATE THIS EVENING...ACROSS THE
ARROWHEAD REGION OF MINNESOTA. LOOK FOR THIS TO BECOME AN INVERTED
TROUGH AND A FOCAL POINT FOR HEAVIER PRECIPITATION AS IT SETS UP
ACROSS CENTRAL UPPER MICHIGAN DURING THE DAY MONDAY. CONVERGENT
NORTHERLY FLOW ALONG THIS AXIS SHOULD BE ASSISTED BY UPSLOPE OFF
LAKE SUPERIOR TO BRING MODERATE TO HEAVY...MAINLY SNOW...TO THE
HIGHER ELEVATIONS OF BARAGA...MARQUETTE...AND POSSIBLY FAR WESTERN
ALGER COUNTY.
THE 06Z AND 12Z NAM RUNS INDICATED ENOUGH DRY AIR AT THE LOWER
LEVELS TO EITHER STOP OR LIMIT PRECIPITATION BETWEEN 00Z AND 18Z
MONDAY FOR MQT/SAW. BOTH THE NAM AND GFS INITIALIZED WEAKER THAN
THEY SHOULD...COMPARED TO THE 12Z SOUNDINGS FROM GRB/APX...10-15KTS
WEAKER AT 250MB. THIS SEEMS TO BE A TREND WITH THE LATEST RUNS...AND
AS SUCH...A SLIGHTLY STRONGER SYSTEM SHOULD BE EXPECTED TO DEVELOP.
WILL HEDGE THE FORECAST SLIGHTLY AWAY FROM THE NAM PREDICTIONS...AS
IT SEEMS TO BE HAVING A TOUGH TIME WITH PRECIPITATION PLACEMENT IN
THE NEAR TERM...AND SEEMED TO BE A COUPLE OF DEGREES TOO WARM THIS
MORNING. HOWEVER...THE NAM SEEMS TO HAVE COME BACK INTO BETTER
AGREEMENT...HAVING A BETTER HANDLE ON A MIX/CHANGE OVER TO SNOW OVER
THE KEWEENAW THIS AFTERNOON. FLURRIES WERE REALIZED AT MOHAWK AT
1630Z. BELIEVE THAT SOME OF THE DRY AIR WILL BE ACCURATE...AS THE
FOCUS REMAINS ACROSS THE WESTERN U.P. OVERNIGHT INTO MID MORNING
MONDAY...BUT HESITATE TO KEEP POPS OUT ENTIRELY OF W-E UPPER
MICHIGAN. THIS DOES PLAY HAVOC WITH THE CURRENT WINTER WEATHER
WATCH FOR CENTRAL UPPER MICHIGAN NEAR LAKE SUPERIOR STARTING AT 06Z
TONIGHT. AFTER COORDINATION WITH THE LONG RANGE FORECASTER...SINCE
PRECIPITATION WILL BE ONGOING...WARNINGS LOOKED REASONABLE FOR
BARAGA AND MARQUETTE. ADVISORIES WILL BE HOISTED WEST FOR MODERATE
TO HEAVY SNOW WEST HALF FROM LATE TONIGHT ON. WARMER TEMPERATURES
SHOULD KEEP ERY MAINLY RAIN.
LONGER TERM...00Z TUE ONWARD...
NAM SHOWING THE 500 MB PATTERN CONSISTS OF A CLOSED 500 MB LOW OVER
NORTHERN IL IN A DEEP TROUGH OVER THE CENTRAL U.S. 00Z TUE WITH
RIDGING IN THE WESTERN U.S. NAM TAKES THIS CLOSED 500 MB LOW SLOWLY
EAST THROUGH TUE AND THEN OPENS UP THE LOW AND TROUGH ON WED OVER
THE LOWER GREAT LAKES.
NAM HAS 850-500 MB Q-VECTOR CONVERGENCE MON NIGHT AND TUE WITH BOTH
MOISTURE AND DYNAMICS STARTING TO DEPART TUE NIGHT. ISENTROPIC LIFT
AND MOISTURE ON I280-I295K SURFACES STARTS TO MOVE OUT ON TUE AS
WELL. GFS SHOWS ABOUT THE SAME THING. BASICALLY...WILL CONTINUE WITH
A RAIN/SNOW MIX FOR MONDAY NIGHT AND TUESDAY WITH THE BEST CHANCE
FOR RAIN ACROSS THE EAST AND THE BEST CHANCE FOR SNOW ACROSS THE
WEST IN THE COLDER AIR. WILL NOT GET TOO FANCY ON THIS RAIN/SNOW MIX
BECAUSE TEMPERATURES ARE VERY BORDERLINE FOR BOTH. IT IS TOO WARM
FOR LAKE ENHANCEMENT AS 850 MB TEMPERATURES ARE -2C TO -4C. IN
FACT...THIS STORM SYSTEM DOES NOT REALLY HAVE THAT COLD OF AIR AT
ALL. THIS MADE FORECASTING SNOW AMOUNTS TOUGH. BASICALLY...THIS WILL
BE A LONG LIVED EVENT WITH THE SNOW BEING VERY WET AND HEAVY ACROSS
THE WEST HALF OF THE CWA. COULD SEE UP TO 15 INCHES IN A FEW PLACES
OVER A SPAN OF 48 HOURS. ISSUED WARNINGS FOR BARAGA AND MARQUETTE
COUNTIES WITH SOME UPSLOPE THROWN IN THERE AS CONFIDENCE IS HIGHEST
THERE. THE REST OF THE WEST HALF EXCEPT FOR MENOMINEE COUNTY WILL
GET CLOSE TO WARNING AMOUNTS AND THIS MIGHT NEED TO BE LOOKED AT FOR
EXPANSION AS WELL. COLDER AIR IS BETTER ENTRENCHED THERE. PROBLEM IS
THERE WILL BE A NARROW BAND OF HEAVY PCPN AND THINKING THIS WILL LIE
ACROSS BARAGA AND MARQUETTE COUNTIES. FURTHER WEST...THIS IS LIGHTER
PCPN TOWARDS THE WESTERN PART OF THE DEFORMATION BAND THAT SETS UP.
TO THE EAST...LIQUID PCPN LONGER...SO HARD TO PINPOINT EXACTLY WHERE
THINGS WILL LINE UP. WARNINGS FOR BARAGA AND MARQUETTE ARE WHERE
CONFIDENCE IS HIGHER...ADVISORIES AND CLOSE TO WARNING AMOUNTS FOR
THE WEST MOSTLY. TUE EVENING...SYSTEM PULLS OUT THEN AND EVENT WINDS
DOWN.
IN THE EXTENDED...GFS...ECMWF AND CANADIAN SHOW A 500 MB RIDGE
ACROSS THE PLAINS WITH TROUGHING ACROSS THE EASTERN U.S. AND OFF THE
PACIFIC NW 00Z THU. THERE IS A HINT OF A SHORTWAVE TROUGH MOVING BY
TO THE NORTH OF THE UPPER GREAT LAKES 00Z FRI BY ALL 3 OF THE MODELS
AS WELL AND SHORTWAVE TROUGHING WITH A SURFACE FRONT PASSING SLOWLY
ACROSS THE AREA AND SETTING UP TO THE SOUTH LOOKS LIKE A GOOD BET
FOR THE WEEKEND. WILL GO WITH A SLIGHTLY WETTER SCENARIO WITH THE
FRONT AROUND THE AREA...BUT NOT GO TOO HIGH ON POPS AND GO SLIGHT
CHANCE OR LOW CHANCES. AS THE FRONT SINKS SOUTH ON SAT AND
SUN...DRIER AIR WILL MOVE INTO THE NORTH AND WENT DRY OR LOWEST POPS
UP THERE AWAY FROM THE FRONT AND CLOSER TO HIGH PRESSURE TO THE
NORTH. TEMPERATURES WILL BE AT OR SLIGHTLY ABOVE NORMAL THROUGH THE
PERIOD.

.AVIATION (FOR THE 00Z TAF ISSUANCE)...
SAW...ARRIVAL OF DRY LLVL AIR AS INDICATED BY SFC DWPT BLO 20 E OF
P53 AND ESC HAS CAUSED CIG AT SAW TO RISE TO VFR RANGE. 18Z NAM
MODEL APPEARS TO HAVE BEST RESOLUTION OF THIS DRY AIR...SO FOLLOWED
THAT MODEL MOS GUIDANCE/FCST SDNGS TO GO WITH A SGNFT CHG IN GOING
FCST TO PREDOMINANT VFR CONDITIONS INTO MON MNRG. STRENGTHENING CYC
NE FLOW ON MON COINCIDENT WITH LO PRES DEEPENING OVER THE LOWER GRT
LKS WL CAUSE CONDITIONS TO DETERIORATE TO PREDOMINANT IFR ON MON
AFTN.
CMX...THIS SITE WL BE CLOSE TO THE BNDRY BTWN DRIER AIR TO THE E AND
MOISTER AIR TO THE W...SO FCST FOR THIS LOCATION IS MORE DIFFICULT
THAN FOR SAW. EXPECT WAVES OF PCPN MOVING S TO N TNGT TO THE E OF
DISTURANCE IN MN TO DROP CONDITIONS TO IFR AT TIMES. BUT CIGS/VSBYS
ARE LIKELY TO IMPROVE BTWN THESE EPISODES...ESPECIALLY WHEN AND IF
THE DRIER LLVL AIR TO THE E CAN MAKE INROADS FARTHER W. THE 18Z NAM/
GFS MODELS BOTH INDICATE THE BEST SHOT FOR SGNFT DRY AIR INTRUSION/
VFR OR HI MVFR CONDITIONS AT CMX WL BE ARND NOON ON MON. LATER IN
THE AFTN...DEEPENING CYC FLOW ARND LO PRES TO THE S WL LIKELY CAUSE
DETERIORATING CONDITIONS.

.MARINE (FOR THE 4 PM LAKE SUPERIOR FORECAST ISSUANCE)...
HIGH PRESSURE JUST EAST OF JAMES BAY WILL SLIDE TO EASTERN QUEBEC BY
MONDAY AFTERNOON...ALLOWING ENE WINDS TO BECOME MORE NORTHERLY AS
THE NEXT SYSTEM APPROACHES MONDAY. LOW PRESSURE OVER SOUTHERN
ILLINOIS AND INDIANA SHOULD DEEPEN SLIGHTLY ACROSS FAR LOWER
MICHIGAN MONDAY AFTERNOON...BEFORE BECOMING NEARLY STATIONARY OVER
CENTRAL LOWER MICHIGAN MONDAY EVENING THROUGH TUESDAY. EXPECT
NORTHERLY WINDS TO 30 KTS MONDAY NIGHT WEST HALF...THEN SOUTH
CENTRAL LAKE SUPERIOR TUESDAY. THE LOW PRESSURE SYSTEM WILL SHIFT TO
FAR SOUTHERN QUEBEC BY WEDNESDAY MORNING...ALLOWING A RIDGE OF HIGH
PRESSURE TO SLIP OVER THE UPPER GREAT LAKES. THE RIDGE WILL MOVE TO
THE LOWER GREAT LAKES FOR THURSDAY AND FRIDAY. LOW PRESSURE
STRETCHING FROM INTERMOUNTAIN WEST THROUGH MANITOBA SHOULD SLIDE
OVER THE NORTHERN PLAINS THURSDAY AFTERNOON...AND OVER THE UPPER
GREAT LAKES FRIDAY.
