AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MARQUETTE MI
543 AM EDT WED JUN 1 2011
.SYNOPSIS...
WV IMAGERY AND RUC ANALYSIS INDICATED A CLOSED MID/UPPER LEVEL LOW
OVER NRN ONTARIO...A RIDE FROM THE NRN ROCKIES TO ALBERTA...AND
ANOTHER LOW OFFSHORE FROM THE PAC NW. AT THE SFC...A TIGHT PRES GRADIENT
BTWN A 993 MB LOW NEAR JAMES BAY AND A RIDGE OVER THE PLAINS HAS
RESULTED IN VERY STRONG WEST WINDS. DECREASING STABILITY WITH CAA
OVERNIGHT HAS HELPED MIX DOWN A PORTION OF 50-55 KT 925-850 MB WINDS
OVER THE WEST HALF OF THE CWA WHERE WINDS HAVE GUSTED INTO THE 40-50
MPH RANGE. THE COLDER AIR ALSO HAS BROUGHT A SC DECK INTO THE NW
HALF OF UPPER MI WHILE A DEPARTING AREA OF 850-500 MB QVECTOR CONV
HELPED SUPPORT SOME LIGHT SPRINKLES THROUGH THE KEWEENAW INTO ERN
LAKE SUPERIOR.
&&
.DISCUSSION...
TODAY...NON CONVECTIVE HIGH WINDS WILL CONTINUE TO INCREASE THIS
MORNING FIRST AS THE PRES RISE AND STRONGER ISALLOBARIC COMPONENT
MOVES THROUGH AND THEN WITH GREATER MIXING WITH THE ONSET OF DAYTIME
HEATING AND CONTINUED CAA. 45-55 KT WINDS INTO THE MIXED LAYER OVER
MUCH OF THE CWA...PER NAM AND RUC...WILL CONTINUE TO SUPPORT WIND
GUSTS INTO THE 40-50 MPH RANGE. OVER THE KEWEENAW TERRAIN ENHANCEMENT
WILL LEAD TO SOME 60 MPH GUSTS...ESPECIALLY FOR WEST FACING HIGHER
ELEVATION LOCATIONS. WINDS SHOULD DIMINISH BY MID TO LATE AFTERNOON
THE LOW SLIDES TO THE EAST A RIDGE BUILDS INTO THE UPPER MS VALLEY.
SOME LIGHT PCPN WILL BE POSSIBLE OVER THE NRN CWA WHICH IS ON THE
EDGE OF THE DEEPER MOISTURE AND CYCLONIC FLOW BUT WITH STRONGER
QVECTOR DIV MOVING IN...NO MORE THAN A FEW SPRINKLES ARE EXPECTED.
TONIGHT AND THURSDAY...HIGH PRES WILL BUILD INTO THE REGION WITH
MOSTLY CLEAR SKIES AND CONTINUED DIMINISHING WINDS AS THE RIDGE AXIS
MOVES OVER CNTRL UPPER MI BY 12Z/THU. FAVORABLE RADIATIONAL COOLING
CONDITIONS LATE WITH PWAT VALUES BLO 0.5 INCH WILL ALLOW TEMPS TO
FALL INTO THE UPPER 30S INLAND WITH LOWER TO MID 40S NEAR THE GREAT
LAKES. AS THE HIGH BUILDS TO THE EAST AND A WARM FRONT DEVELOPS
AHEAD OF LOW PRES MOVING INTO THE PLAINS...CLOUDS WILL INCREASE FROM
SW TO NE BY LATE IN THE DAY.
THURSDAY NIGHT AND FRIDAY...MODELS HAVE BEEN FAIRLY CONSISTENT IN
SHOWING AN INTENSE BAND OF ISENTROPIC LIFT/FGEN (AT LEAST 50 KT
INFLOW) SETTING UP FROM NEAR CYQT/KINL INTO UPPER MI. THE NAM HAS
BEEN THE MOST AGGRESSIVE WITH QPF AMOUNTS SHOWING 1 TO 3 INCH
AMOUNTS POSSIBLE. THIS WOULD NOT BE UNREASONABLE GIVEN THE STRONG
INFLOW OF MOISTURE WITH PWAT VALUES TO NEAR 1.7 INCHES AVBL UPSTREAM
AND POTENTIAL FOR TRAINING CELLS. CONFIDENCE ON THE LOCATIONS OF
SUCH A RELATIVELY NARROW HEAVIER PCPN BAND WAS LOWER GIVEN EXPECTED
DIFFERENCES IN FINER DETAILS.
&&
.AVIATION /FOR THE 06Z TAF ISSUANCE/...
EXPECT SLOWLY VEERING/GUSTY W WINDS...STRONGEST AT THE MORE EXPOSED
CMX LOCATION...THRU MUCH OF THE DAY UNDER SHARP PRES GRADIENT ON THE
SRN FLANK OF LO PRES CROSSING ONTARIO. THE STRONGEST WINDS SHOULD
OCCUR THIS MRNG WITH ARRIVAL OF THERMAL TROF/APRCH OF AXIS OF
SHARPER PRES RISES BEHIND PASSAGE OF LO PRES TROF. WINDS WL BEGIN TO
DIMINISH LATER TODAY AS THE LO TO THE NE MOVES FARTHER AWAY AND HI
PRES APRCHS FM THE W. OTRW...VFR CONDITIONS WL PREDOMINATE. THE ONLY
EXCEPTION WL BE AT CMX FOR A PERIOD THIS MRNG WHEN SOMEWHAT DEEPER
BACKWASH MSTR AS SHOWN ON THE 00Z INL RAOB AND THE MORE CYC/UPSLOPE
FLOW BEHIND THE TROF BRINGS A PERIOD OF MVFR CIGS TO THAT LOCATION.
&&
.MARINE /4 AM LAKE SUPERIOR ISSUANCE/...
WEST GALES ONGOING AS STRONG LOW PRES MOVES OVER JAMES BAY IN
NORTHERN ONTARIO. DUE TO THE STABLE MARINE LAYER THE STRONGEST WINDS
WILL NOT BE REALIZED NEAR THE WATER/BUOY LEVEL...HOWEVER WINDS AT
SHIP LEVEL WILL LIKELY BE QUITE GUSTY WITH PERHAPS A FEW GUSTS NEAR
STORM FORCE. WINDS WILL RAPIDLY DIMINISH LATE THIS AFTN INTO THIS
EVENING AS HIGH PRES BUILDS INTO THE AREA. WINDS REMAIN LIGHT
THROUGH THURSDAY...BUT WILL INCREASE THURSDAY NIGHT INTO FRIDAY AS
A WARM FRONT LIFTS TOWARD THE REGION. MAY SEE SE WINDS NEARING GALE
FORCE OVR NCNTRL LK SUPERIOR ON FRIDAY IN DEVELOPING TIGHT PRESSURE
GRADIENT. COLD FRONT SWEEPS THROUGH LATE FRIDAY NIGHT INTO SATURDAY.
THERE COULD BE SOME GUSTS TO GALES ON SATURDAY BEFORE HIGH PRES
BUILDS IN BY SUNDAY.
