AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MARQUETTE MI
455 PM EDT TUE JUL 27 2010

.SYNOPSIS...
WV IMAGERY AND RUC ANALYSIS INDICATED A MAINLY ZONAL PATTERN ACROSS
THE NRN CONUS. A MID/UPPER LEVEL TROUGH WAS LOCATED OVER MANITOBA
WITH A 100 KT 250-300 MB JET INTO WRN ONTARIO. AT THE SFC...A
TROUGH/FRONT WAS LOCATED OVER NW MN. RADARS THE MAIN BATCH OF
CONVECTION OVER N CNTRL MN BTWN KDLH/KFAR WHILE MAINLY JUST SOME
LIGHT SHOWERS OR SPRINKLES WERE MOVING INTO S UPPER MI AS MCV FROM
DECAYING CONVECTION EARLIER TODAY.
&&

.SHORT TERM...TONIGHT AND WEDNESDAY

ALTHOUGH CLOUDS FROM THE SHRA/TSRA OVER NRN WI HAVE LIMITED SFC
HEATING/INSTABILITY...PARAMETERS REMAIN IN PLACE TO SUPPORT
STRONG/SEVERE TSTMS INTO UPPER MI. AS THE COLD FRONT
ADVANCES AND LARGE SCALE LIFT INCREASES AHEAD OF THE MID LEVEL
TROUGH AND WITH THE RIGHT ENTRANCE OF THE UPPER LEVEL JET...TSTMS
ARE EXPECTED TO DEVELOP/SPREAD INTO WEST UPPER MI THIS EVENING AND
THROUGH THE REST OF THE CWA BY LATE EVENING AND OVERNIGHT. 0-6KM
SHEAR TO NEAR 40KT WILL SUPPORT ORGANIZED STRONG TO SEVERE STORMS
WITH POTENTIAL FOR SUPERCELLS. FAVORABLE 0-1KM AND 0-3KM HELICITY
VALUES COULD ALSO SUPPORT AN ISOLD TOR. STRENGTHENING MID LEVEL
WINDS/DRYING WOULD ENHANCE DAMAGING WIND THREAT AS THE CONVECTION
LIKELY TRANSITIONS TO MORE OF A LINEAR MCS OR SQUALL LINE...PER SPC.
EXPECT THE FRONT AND SHRA/TSRA TO ACCELERATE DURING THE EVENING WITH
MOST PCPN EXITING THE CWA BY 09Z.

STRONG DRYING AND SUBSIDENCE BEHIND THE FRONT SHOULD BRING
CLEARING/SUNNY SKIES FOR WED.  GUSTY WEST WINDS ARE
EXPECTED...ESPECIALLY OVER THE KEWEENAW WHERE TERRAIN WILL ENHANCE
WINDSPEEDS. TEMPS SHOULD AGAIN CLIMB TO AROUND 80 WITH SOME
DOWNSLOPE WARMING CNTRL.

.LONG TERM /WED NIGHT THROUGH NEXT TUESDAY/...

WED NIGHT...HIGH PRESSURE WILL BE BUILDING INTO THE REGION TO START
THE LONG TERM PERIOD...WHICH WILL GRADUALLY DIMINISH WINDS ACROSS
THE AREA. A SECONDARY COLD FRONT SHOULD BRUSH THE NE HALF OF THE
AREA...WITH CLOUDS FROM THIS FRONT LARGELY DETERMINING LOWS. BUMPED
CLOUD COVER UP SIGNIFICANTLY OVER THE FAR NE PART OF THE CWA...WHERE
THE DEEPEST MOISTURE AND STRONGEST H925-850 CAA IS EXPECTED. NOT AS
CONFIDENT AS YOU GO FARTHER SW ACROSS THE CWA...BUT DID BUMP SOME OF
THE CNTRL AREAS TO PARTLY CLOUDY. AS FOR TEMPS...PWAT VALUES AROUND
65 PERCENT OF NORMAL OVER THE W HALF AND LESS CLOUDS SHOULD ALLOW
FOR SOME RAD COOLING...BUT LINGERING WINDS IN THE EVENING SHOULD
HELP KEEP THE TEMPS IN CHECK. OVERALL...WENT WITH SLIGHTLY BELOW
NORMAL VALUES OVER THE INTERIOR W...RIGHT AROUND 50 DEGREES.

THINK THERE WILL BE SOME LINGERING CLOUDS OVER THE EAST DURING THURS
MORN...AS THE FRONT EXITS THE REGION. OTHERWISE...HIGH PRESSURE WILL
BECOME CENTERED OVER UPPER MI THURS AFTN AND THEN EVENING...BEFORE
DRIFTING SE OF THE AREA BY FRI MORNING. HIGHS ON THURS SHOULD BE
MUCH COOLER THAN WE HAVE SEEN OVER THE LAST COUPLE OF DAYS. CURRENT
FCST MAY BE A TOUCH ON THE OPTIMISTIC SIDE FOR HIGHS ON THURS...WITH
CURRENT FORECAST IN THE LOW/MID 70S...WARMEST WEST...AND UPPER 60S
ALONG ERN LK SUPERIOR. H850 TEMPS AROUND 8-10C WOULD YIELD TEMPS IN
THE UPPER 60S TO LOWER 70S...BUT ANY CLOUD COVER LINGERING INTO THE
AFTN WOULD CUT TEMPS DOWN A COUPLE MORE DEGREES. DID TRY TO HINT AT
SOME MID/HIGH CLOUDS MOVING IN OVER THE FAR W ON THURS NIGHT IN
ADVANCE OF SHORTWAVE RIDING OVER THE RIDGE.

FOR DAYS 3 THROUGH 7 /FRIDAY INTO NEXT TUESDAY/...PERIOD BEGINS
UNDER NW FLOW ALOFT WITH A TROUGH OVER THE ERN CONUS AND WEAK RIDGE
OVER THE ROCKIES. MODELS HINTING AT A WEAK SHORTWAVE EJECTED FROM
THE UPPER TROUGH OFF THE WRN CONUS TODAY THAT WILL WORKS IT/S WAY UP
OVER THE RIDGE AND THEN SLIDE ACROSS THE AREA FRI INTO FRI NIGHT.
00Z ECMWF/GFS AND 12Z UKMET ARE FAIRLY SIMILAR WITH THE LARGE SCALE
UPPER FEATURES...ALTHOUGH 00Z GEM SHOWS A STRONGER RIDGE MOVING OFF
THE ROCKIES. THEREFORE...FOLLOWING THE HPC PREFERRED 00Z ECMWF SOLN
FOR THE PERIOD. OVERALL...SHORTWAVE IS FAIRLY WEAK AS IT MOVES
ACROSS THE UPPER GREAT LKS FRI INTO FRI NIGHT. BOUNDARY FROM COLD
FRONT PASSING THROUGH TONIGHT AND HIGH PRESSURE BEHIND IT WILL KEEP
IT WELL S OF THE AREA...SRN MN INTO NRN IL. THUS...THINK MAIN
INSTABILITY AND CONVECTION WILL REMAIN FARTHER S AND WE WILL BE LEFT
WITH ANY MID-LVL FORCING FROM THE SHORTWAVE. PER THE ECMWF...BEST
FORCING FOR THIS AREA ON DIVQ AND ISENTROPIC CHARTS WILL BE BETWEEN
H700-500...WHICH LEADS TO MORE OF A LOW POP/QPF FORECAST.
THEREFORE...DECIDED TO START THE TREND TOWARDS POPS BY ADDING SLIGHT
CHANCES IN...NO THUNDER...FOR THE ENTIRE AREA FRI INTO FRI NIGHT.
BEHIND THE WEAK SHORTWAVE...AREA REMAINS IN WEAKENING NW FLOW DURING
THE WEEKEND...AS UPPER RIDGE OVER THE SRN PLAINS BUILDS.
TIMING/POSITION OF SHORTWAVES MOVING THROUGH THIS TYPE OF SETUP ARE
NEARLY IMPOSSIBLE TO FORECAST IN THE EXTENDED PART OF THE FORECAST.
THEREFORE...LEFT THE WEEKEND DRY FOR NOW...ALTHOUGH THERE COULD BE
ANOTHER WAVE PUSHING THROUGH ON SUN AS THE RIDGE APPROACHES. WAA
WILL CONTROL THE AREA MON AHEAD OF A NRN STREAM TROUGH IN CANADA
DROPPING A COLD FRONT ACROSS THE AREA FOR MON NIGHT AND TUES. COULD
SEE SOME PCPN ON MON...BUT WENT WITH CHANCE POPS FOR THE BETTER
FORCING WITH THE COLD FRONT. EXPECT TEMPS DURING THIS PERIOD TO BE
NEAR NORMAL...AS H850 TEMPS SHOULD BE IN THE 10-14C RANGE...WITH
SLIGHTLY WARMER TEMPS ON MON.
&&

.AVIATION /FOR THE 18Z TAF ISSUANCE/...

THUNDERSTORMS ARE EXPECTED AT KCMX EARLY THIS AFTERNOON WHILE MAINLY
VFR CONDITIONS PRVAIL AT KSAW WITH GUSTY SRLY WINDS. TONIGHT...TSRA
ARE ALSO EXPECTED AHEAD OF A FRONT THAT WILL MOVE THROUGH UPPER
MICHIGAN OVERNIGHT. MVFR CIGS ARE EXPECTED WITH THE SHRA/TSRA ALONG
WITH SOME STRONG WRLY WINDS. GUSTY WRLY WINDS WILL PREVAIL BEHIND THE
FRONT AT KCMX WITH TERRAIN ENHANCEMENT HELPING TO BOOST WINDSPEEDS.
AFTER ANY SHRA/TSRA AND THE FRONT MOVES THROUGH...MAINLY VFR
CONDITIONS ARE EXPECTED.
&&

.MARINE (FOR THE 4 PM ISSUANCE)...

EXPECT A STRONG COLD FRONT TO CROSS LAKE SUPERIOR TONIGHT. STRONG
SOUTH WINDS LATE THIS AFTERNOON..LIMITED SOMEWHAT BY THE HIGH STABILITY
BROUGHT ABOUT BY THE PASSAGE OF THE WARM AIRMASS OVER THE RELATIVELY
COOL WATERS OF LAKE SUPERIOR...WILL VEER WEST FOLLOWING THE PASSAGE
OF THIS FRONT TONIGHT. THE STONGEST WEST WINDS UP TO 30 KNOTS
TONIGHT INTO WEDNESDAY WITH GRADUALLY DECREASING STABILITY ARE MOST
LIKELY OVER THE WEST BETWEEN THE KEWEENAW AND ISLE ROYALE AND THE
EAST THIRD WHERE THE TERRAIN WILL ENHANCE THE WEST WINDS. THE
ARRIVAL OF A WEAKER PRESSURE GRADIENT AFTER WEDNESDAY WILL CAUSE
WINDS TO DIMINISH UNDER 25 KNOTS. WINDS ARE THEN EXPECTED TO REMAIN
AOB 20 KT FROM THU THROUGH SAT.
