Area forecast discussion, Jul 30, 4:47 PM EDT, 1 hour 12 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MARQUETTE MI
447 PM EDT SAT JUL 30 2011

.SHORT TERM /THROUGH SUNDAY/...

SHOWERS AND THUNDERSTORMS AHEAD OF A CONVECTIVELY INDUCED SHORTWAVE
OVER MN HAVE MOVED INTO THE CENTRAL FORECAST AREA. MESOANALYSIS
INDICATES AROUND 2500J/KG OF SBCAPE AND LITTLE TO NO CIN...STORMS
ARE EXPECTED TO CONTINUE T MOVE/DEVELOP OVER THE CENTRAL CWA THIS
AFTERNOON INTO THIS EVENING. DESPITE WEAKENING NATURE OF LINE IN OUR
CWA AS OF LATE...ENHANCED WIND DAMAGE THREAT WILL PERSIST AS STORMS
ARE MOVING INTO GREATER DCAPE AROUND 1000J/KG. WIND SHEAR IS FAIRLY
WEAK AT 25-35KTS...SO STORMS SHOULD NOT BECOME INCREDIBLY ORGANIZED.
NORTHERN BOUND FOR MOST OF THE CONVECTION WILL BE THE LAKE SUPERIOR
BREEZE...WHICH WILL REMAIN FAIRLY CLOSE TO SHORE GIVEN STEADY SW
WINDS...AND MAY ACT TO LOCALLY INTENSIFY STORMS. STORM COVERAGE OVER
THE ERN CWA SHOULD BE MORE LIMITED TO NEAR THE LAKE BREEZE
CONVERGENCE CLOSER TO LAKE SUPERIOR...THIS IS DUE TO LAKE MICHIGAN
MODERATION WITH THE SW WINDS OVER THAT AREA. GIVEN THE CURRENT
MAINLY LINEAR STRUCTURE OF THE STORMS...STRONG TO SEVERE WINDS
APPEARS TO BE THE PRIMARY THREAT /AND THERE HAVE BEEN SOME SEVERE
WIND REPORTS OVER WRN UPPER MI/...BUT THERE IS A LARGE HAIL THREAT
AS WELL...ESPECIALLY IN STORMS THAT DEVELOP AHEAD OF THE MAIN LINE.
TORNADO POTENTIAL APPEARS VERY LOW GIVEN WEAK SHEAR AND LINEAR
NATURE OF STORMS.

TONIGHT AND SUNDAY...A STACKED CLOSED LOW WILL MOVE INTO NRN ONTARIO/SRN
HUDSON BAY...DRAGGING A SFC TROUGH/COLD FRONT ACROSS THE CWA. THE
COLD FRONT WILL ENTER THE WRN CWA AROUND 00Z SUNDAY...GO THROUGH THE
CENTER OF THE CWA AROUND 10Z...AND EXIT S/SE OF THE CWA BY 18Z
SUNDAY. WITH THE FRONT MOVING THROUGH DURING THE COOLEST PART OF THE
DAY WITH THE LEAST INSTABILITY AND THE BEST FORCING STAYING WELL TO
THE NORTH...KEPT LOW TO MID CHANCE POPS EXPECTING THE PRECIP TO BE
MORE SCATTERED IN NATURE. PLUS...VERY DRY MID LEVEL AIR WILL QUICKLY
MOVE IN BEHIND THE FRONT...FURTHER LIMITING PRECIP COVERAGE.

.LONG TERM DISCUSSION /SUN NGT THRU SAT/...

SUN NGT...AFT ANY LINGERING SHRA OVER THE FAR SCNTRL END IN THE EVNG
WITH LOSS OF DIURNAL HEATING AND DRYING ALF AHEAD OF APRCHG RDG
AXIS...EXPECT A TRANQUIL NGT WITH HI PRES BLDG OVER NW WI BY 12Z
MON. WITH PWAT AS LO AS 0.60 INCH...EXPECT MIN TEMPS NEAR THE LO END
OF GUIDANCE ESPECIALLY OVER THE INTERIOR W...CLOSER TO INCOMING HI
CENTER/WEAKER WINDS. STRONGER NW H925 WINDS OFF LK SUP WL TEND TO
MINIMIZE DIURNAL TEMP FALL OVER THE E.

MON...AS RDG ALF BLDS INTO THE UPR LKS...SFC HI CENTER IS PROGGED TO
DRIFT OVER NRN LK MI BY 00Z TUE. THE RESULT SHOULD BE A MOSUNNY
DAY...BUT STRENGTHENING SW FLOW ON THE BACK SIDE OF HI CENTER WL
BRING A RETURN OF HIER PWAT...SOME HI CLDS TO THE W IN THE AFTN.
DESPITE THE MSTR RETURN...SHARP SUBSIDENCE INVRN SHOWN ON FCST SNDGS
ASSOCIATED WITH THE RDGING WL KEEP A LID ON ANY SHRA/TS. WITH H85
TEMPS RISING TO ARND 20C BY LATE IN THE DAY OVER THE W... MIXING TO
H75-8 ON GFS FCST SDNGS WOULD SUPPORT HI TEMPS PEAKING AS HI AS THE
LO 90S OVER THE INTERIOR W HALF. WEAK PRES GRADIENT WL ALLOW FOR LK
BREEZES TO DVLP AND BRING SOME COOLING TO AREAS NEAR THE LKS.

MON NGT/TUE...NEXT SHRTWVS OF CONCERN WL MOVE INTO AND THRU THE UPR
RDG OVER THE GRT LKS. MODELS IN GOOD AGREEMENT SHOWING THE STRONGER
DISTURBANCE PLOWING E WELL TO THE N IN CNTRL CAN...BUT SYS OF MOST
CONCERN TO UPR MI IS FCST TO MOVE FM THE NRN PLAINS TO WRN LK SUP BY
12Z TUE AND THEN ACRS UPR MI INTO SE ONTARIO ON TUE. THE 12Z
MODELS...ESPECIALLY THE GFS OVERDEEPENS THE SFC LO...SO TENDED TO
FOLLOW THE WEAKER 12Z CNDN/06Z GFS MODELS FOR FCST DETAILS. SINCE
THIS GUIDANCE SHOWS H85 WARM FNT FARTHER N THAN EARLIER RUNS...THIS
GUIDANCE GENERATES HIER QPF OVER THE FA THAN BEFORE. THE CNDN MODEL
INDICATES SW H85 WINDS UP TO 40-45KTS ADVECTING H85 DWPTS UP TO 18C/
SSI DOWN TO -3C INTO THE CWA BY 12Z TUE UNDER THE VIGOROUS H85-5
QVECTOR CNVGC AHEAD OF THE INCOMING SHRTWV. THESE DYNAMICS/MSTR
RETURN SUPPORT RAISING POPS TO LIKELY...WITH A WDSPRD RA PSBL OVER
MUCH OF UPR MI. AS THE SHRTWV PASSES TO THE E...DRIER AIR WL ARRIVE
FM THE NW AND DIMINISH THE PCPN CHCS IN THE AFTN. EXPECT A VERY WARM
OVERNGT ON MON NGT ESPECIALLY OVER THE W IN DOWNSLOPE AERAS NEAR LK
SUP FM IWD-P59-MQT WITH INCRSG SW FLOW/MSTR RETURN. DESPITE THE WARM
START...TEMPS ON TUE SHOULD BE HELD DOWN BY RA COOLED AIR AND
CONVECTIVE DEBRIS CLD.

IN THE EXTENDED PERIOD...UPR MI WL REMAIN UNDER THE ZONAL FLOW ALF
THAT DOMINATES SRN CAN/NRN TIER CONUS TO THE N OF SPRAWLING UPR RDG
CENTERED ACRS THE SCNTRL PLAINS. TIMING/IMPACT SO FAR IN THE FUTURE
OF DISTURBANCES EMBEDDED WITHIN THIS TRICKY FLOW IS THE MAIN FCST
CHALLENGE. UNFORTUNATELY...LATEST OPS MODEL GUIDANCE SHOWS USUAL
VARIABILITY THAT WOULD BE EXPECTED IN THIS TYPICAL SUMMER PATTERN...
SO CONFIDENCE IN THE EXTENDED PERIOD IS MINIMAL. THERE APPEARS TO BE
CLEAR CONSENSUS THAT WED WL BE DRY AS HI PRES FOLLOWS IN THE WAKE OF
DISTURBANCE RESPONSIBLE FOR SHRA CHCS ON TUE. GIVEN THE SPREAD IN
FCST SCENARIOS AFT WED...OPTED TO FOLLOW NCEP MANUAL GUIDANCE FOR
EXTENDED GRIDS PREPARATION. THIS GUIDANCE UNTILIZED A COMBINATION OF
THE 00Z ECMWF/GFS ENSEMBLE MEANS AND SHOWS HI PRES GIVING WAY TO
APRCHG SHRTWV/SFC COLD FNT ON THU WITH FROPA THU NGT. HI PRES IS
THEN PROGGED TO BLD INTO THE UPR LKS ON FRI INTO SAT. AS FOR
TEMPS... EXPECT ABV NORMAL READINGS ON WED THRU THU WITH FCST H85
TEMPS IN THE UPR TEENS C. TEMPS WL LIKELY COOL A BIT NEXT FRI/SAT
BEHIND THE COLD FROPA WITH FCST H85 TEMPS DROPPING TO ARND 15C.

&&

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

VFR CONDITIONS SHOULD CONTINUE AT BOTH SITES THROUGH AT LEAST EARLY
SATURDAY EVENING. ALTHOUGH THERE COULD BE SOME PATCHY GROUND FOG
ACROSS UPPER MICHIGAN OVERNIGHT TONIGHT GIVEN THE INCREASED MOISTURE
ACROSS THE AREA. HOWEVER...CONFIDENCE IS NOT HIGH ENOUGH TO INCLUDE
IN THE TERMINALS. WINDS WILL BE A LITTLE WEAKER ON SATURDAY COMPARED
TO FRIDAY. THIS SHOULD ALLOW A STRONGER LAKE BREEZE AT SAW SAT
AFTERNOON. OTHERWISE...CONVECTION OVER THE WESTERN DAKOTAS
ASSOCIATED WITH A COLD FRONT WILL ATTEMPT TO MOVE INTO UPPER MI LATE
SAT AFTN INTO SAT NIGHT. STILL UNCLEAR IF THE STORMS WILL SURVIVE AS
THE MOVE INTO UPPER MICHIGAN GIVEN THE DRY AIR ACROSS THE AREA AND
HAVE NOT INCLUDED ANY MENTION OF TS IN THE TERMINALS. HAVE OPTED TO
BRING CIGS DOWN TO 5000 FT BY SAT EVENING FOR BOTH SITES AS THE
FRONT APPROACHES THE AREA.

&&

.MARINE /FOR THE 4 PM LAKE SUPERIOR FORECAST ISSUANCE/...

WINDS SHOULD REMAIN AT OR BELOW 25 KTS THROUGH THE FORECAST PERIOD.
HIGH PRESSURE WILL BE IN CONTROL...EXCEPT FOR WHEN LOW PRESSURE
TROUGHS PASS OVER THE AREA LATE TONIGHT INTO SUNDAY MORNING...THEN
AGAIN ON TUESDAY. SCATTERED THUNDERSTORMS MAY OCCUR AS THESE TROUGHS
MOVE THROUGH.
