AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE MARQUETTE MI 314 PM EDT SAT JUN 13 2009 UPDATE FOR 00Z TAF ISSUANCE .SYNOPSIS... 12Z RAOBS/LATEST WV IMAGERY AND RUC ANALYSIS SHOW CYC NW FLOW ALF OVER THE UPR GRT LKS ON SRN FLANK OF PERSISTENT UPR TROF OVER HUDSON BAY. A FAIRLY STRONG SHRTWV IS EMBEDDED WITHIN THIS NW FLOW AND MOVING INTO NRN MN THIS AFTN. A BAND OF MID CLD IN ADVANCE OF THIS FEATURE MOVED INTO W AND CNTRL UPR MI...BUT FAIRLY DRY LLVLS AS DIAGNOSED ON NAM/LOCAL WRF-ARW SDNGS INITIALLY LIMITED THE DVLPMNT OF MORE THAN AN ISOLD -SHRA. MORE SHRA/SOME TS DVLPD JUST TO THE E OF THIS CLD MASS AS TEMPS REACHED CONVECTIVE TEMPS IN THE LO 70S AND INLAND FM THE LK BREEZE OFF LK MI. ANOTHER BAND OF SHRA HAS DVLPD OVER NCNTL MN NEAR AXIS OF SHARPER H85-7 FGEN BTWN LLVL NW FLOW OVER NRN MN DVLPG UNDER UPR SHRTWV/BEHIND ATTENDANT COLD FNT AND MORE SW FLOW OVER SRN MN. THESE SHRA/TS HAVE MOVED INTO NW WI AS OF 19Z. && .SHORT TERM (TONIGHT AND SUNDAY)... MAIN FCST CONCERNS THRU SUN ARE SHRA/TS CHCS THE REST OF TDAY INTO EARLY SUN. FOR TNGT...WITH SOME CLRG LIKELY LATE THIS AFTN OVER THE W BEHIND DEPARTING CLD BAND IN CONCERT WITH SOME H85 THETA-E ADVCTN AHEAD OF INCOMING SFC COLD FNT...SUSPECT ISOLD -SHRA/-TS WL DVLP OVER THE FA. BUT DRYNESS OF LLVLS WL TEND TO LIMIT COVERAGE...SO CUT POPS A BIT. BOTH THE NAM/LOCAL WRF-ARW SHOW DRYING/STABILIZATION OFF WRN LK SUP WL LIMIT PCPN CHCS OVER THE W...AT LEAST N OF ONTONAGON. NAM SHOWS BAND OF FGEN PCPN IN NCNTRL MN TENDING TO SLIDE MORE SE INTO NW WI...BUT HIER POPS WL LIKELY CLIP AREA NEAR THE WI BORDER AT NOSE OF AXIS OF HIER H85 THETA-E THRU THIS EVNG. OTRW...ARRIVAL OF COLD FNT OVER THE W LATE THIS EVNG WL BRING A SLGT CHC OF -SHRA...WITH COVG/INTENSITY LIMITED BY DRY ADVECTION ALF AND NOCTURNAL COOLING. THIS BNDRY IS FCST TO REACH THE SE ZNS BY 12Z SUN. SFC COLD FNT WL CLEAR THE SE ZNS TMRW MRNG...FOLLOWED BY HI PRES UNDER CONFLUENT NW FLOW ALF IN THE WAVE OF THE SHRTWV. DEEP LYR QVECTOR DVGC AND THE ARRIVAL OF MUCH DRIER AIR WL ENSURE PLENTY OF SUNSHINE...BUT CARRIED A LO CHC POP OVER THE SE WHERE 12Z NAM SHOWS KINX ARND 25 UNTIL THE FNT CLRS THAT AREA AFT 15Z. MIXING TO H7-75 ON FCST SDNGS YIELDS HI TEMPS IN THE MID/UPR 70S AWAY FM THE MODERATING INFLUENCE OF THE GRT LKS...FOCUSED DOWNWIND OF LK SUP WITH SYNOPTIC SCALE NNW FLOW. && .LONG TERM (SUNDAY NIGHT THROUGH SATURDAY)... THE 500MB TROUGH THAT IS CURRENTLY OVER NORTHERN ONTARIO WILL SLIP SOUTH-SOUTHEAST ALONG THE SE BORDER OF OUR CWA TO BEGIN THE PERIOD. AT THIS POINT WE WILL BE LOOKING WESTWARD AT THE SIZABLE RIDGE ENCOMPASSING MEXICO THROUGH THE CENTRAL PLAINS TO MOVE OUR WAY. EXPECT DRY WEATHER SUNDAY NIGHT THROUGH THE DAY TUESDAY. STILL 850MB TEMPERATURES WILL REMAIN IN THE 10 TO 12C RANGE...WITH AFTERNOON HIGH TEMPERATURES TOPPING OUT IN THE UPPER 60S TO LOWER 70S NEAR THE GREAT LAKES...AND IN THE MID AND UPPER 70S INLAND. WITH HIGH PRESSURE OVERHAD AT THE SURFACE AND ALOFT...EXPECT LAKE BREEZES TO DOMINATE EACH AFTERNOON. THE 500MB RIDGE SHOULD BE DIRECTLY OVERHEAD TUESDAY MORNING....AS WE BEGIN TO LOOK TO THE NORTHERN PLAINS FOR A TROUGH WORKING THROUGH THE OTHERWISE SOUTHWESTERLY FLOW OVER THE WESTERN HALF OF THE NATION. AT THE SURFACE...THINGS BECOME MORE JUMBLED AS OUR RIDGE SLOWLY EXITS EASTWARD. PLAYED UP LAKE BREEZES DURING THE AFTERNOON HOURS...AND LOWERED HIGH TEMPS NEAR THE GREAT LAKES SLIGHTLY. NOT TOO EXCITED ABOUT THE CHANCE OF PRECIPITATION WEDNESDAY NIGHT...BUT WILL KEEP A SLIGHT CHANCE OF MAINLY -SHRA...AS WE SHOULD BE IN BETWEEN SFC SYSTEMS...EVEN THOUGH THE 500MB TROUGH WILL BE SLIDING OVERHEAD. WILL GO CLOSE TO HPC GUIDANCE FOR DAYS 4/WEDNESDAY THROUGH DAY 7/SATURDAY. THE 500MB HIGH/RIDGE WILL REMAIN OVER THE SOUTHERN PLAINS AND NEW MEXICO. THIS WAS A MIX BETWEEN THE ECMWF ENSEMBLE MEAN...ECMWF...AND GEFS MEAN. && .AVIATION (FOR THE 00Z TAF ISSUANCE)... VFR CONDITIONS EXPECTED AT BOTH TAF SITES THROUGH THE PERIOD. REMNANTS OF CONVECTION OVER WRN U.P. WILL BRING SOME -RA TO SAW FOR AN HOUR OR TWO AT START OF FCST BUT CIGS/VSBY SHOULD REMAIN IN VFR RANGE. WEAK FRONT WILL PASS THROUGH AREA OVERNIGHT TONIGHT SHIFTING WINDS TO A MORE NORTHWESTERLY DIRECTION. THERE IS A POTENTIAL FOR A PD OF LO CLD AT CMX TNGT WITH UPSLOPE WLY FLOW FOLLOWING THE COLD FRONTAL PASSAGE. WL MENTION JUST SCT LO CLD ATTM GIVEN APRNT DRYNESS OF LLVLS IN NRN MN. MUCH DRIER AIR WL ARRIVE SUN MRNG AND BRING VFR CONDITIONS AS DAYTIME HEATING MIXES THIS DRY AIR TO THE SFC. && .MARINE (FOR THE 4 PM LAKE SUPERIOR ISSUANCE)... EXPECT NO WINDS IN EXCESS OF 20 KTS THIS FORECAST PERIOD. ALTHOUGH A DEEPER LO PRES SYSTEM WILL APPROACH THE UPPER GREAT LAKES LATE THIS COMING WEEK...STABLE MARINE LAYER BLANKETING THE LAKE ABOVE WATER TEMPERATURES OF LESS THAN 39F WILL ENSURE WINDS NO HIER THAN 20 KNOTS THEN AS WELL. && .MQT WATCHES/WARNINGS/ADVISORIES...NONE. && SYNOPSIS/SHORT TERM...KC LONG TERM...KF AVIATION...MZ MARINE...KC
