NWS Gaylord, MI wrote its last area forecast discussion before the first event at Jun 27, 1:47 PM EST, 6 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GAYLORD MI 247 PM EDT WED JUN 27 2007 .DISCUSSION...THE SFC LOW ON THE QUEBEC/ONTARIO BORDER HAS AN ASSOCIATED COLD FRONT THAT STRETCHES FROM ABOUT APN TO NEAR CAD. THE COLD FRONT IS KICKING OFF THUNDERSTORMS JUST OUT AHEAD OF IT AS WELL AS SHOWERS ALONG THE FRONT. AT 500 MB, THE SHORTWAVE TROUGH IS ENTERING LAKE SUPERIOR. BEHIND THE FRONT, TEMPERATURES IN C AND W UPPER ARE AROUND 80F WITH THE TD NOW IN THE LOWER 50S. THE MAIN CONCERN WITH THE FORECAST PACKAGE WILL THIS EVENING WITH THE FRONT AND THE COOL AIR THROUGH THURSDAY. THE MODELS ARE IN GOOD AGREEMENT WITH THE SHORT TERM PORTION OF THE FORECAST. SO HAVE TAKEN A BLEND. TONIGHT...THE FRONT LOOKS TO BE NEAR DTW BY 06Z THE GFS HAS ALL OF THE PRECIPITATION OUT OF THE FORECAST AREA FOR THE EVENING WITH THE NAM HAVING JUST A TOUCH NEAR THE LAKE HURON SHORE ALONG IOSCO AND ARENAC COUNTIES. SO FOR THE EVENING HAVE CHANCE POPS IN THE EVENING FOR GLADWIN AND ARENAC THEN NO SIG WEATHER FOR THE OVERNIGHT PERIOD. AS LOOKS LIKE TEMPERATURES WILL BE IN THE LOWER TO MID 50S FOR THE OVERNIGHT AS THE COOLER AIR FILTERS INTO THE REGION OVERNIGHT. THURSDAY...HIGH PRESSURE BUILDS INTO THE REGION. THE 850 MB RH BEGINNING TO FALL OFF DURING THE DAY, HOWEVER WITH THE 700-500 MB RH AT LESS THAN 10% WOULD EXPECT THAT MOST OF THE CLOUDS WILL BEGIN TO WHITTLE DOWN TO SCATTERED CLOUDS. BY THE AFTERNOON THE 850 MB RH FALLS TO LESS 40% SO EXPECTING THAT IT WILL BE MOSTLY SUNNY FOR THE AFTERNOON. THE SFC COOL AIR REALLY POURS INTO THE REGION SO THAT THE HIGHS ONLY REACH INTO THE MID TO UPPER 60S. LUTZ LATER PERIODS (THURSDAY NIGHT THROUGH NEXT WEDNESDAY)...A QUIET AND SPLENDID STRETCH OF WEATHER APPEARS ON TAP FOR MUCH OF THE EXTENDED PORTION OF THE FORECAST. MODELS HAVE COME INTO PRETTY GOOD AGREEMENT REGARDING THE DEVELOPMENT OF OMEGA BLOCKING OVER THE INTERMOUNTAIN WEST/PLAINS...WITH DOWNSTREAM TROUGH AMPLIFICATION TAKING PLACE ACROSS THE GREAT LAKES AND THROUGH THE NORTHEAST. AT THE SURFACE...EXPANSIVE RIDGE AXIS PROGGED TO EVER SO SLOWLY SHIFT FROM ALBERTA/SASKATCHEWAN TOMORROW TO THE GREAT LAKES BY THE WEEKEND. RESULTANT NORTH/NORTHWEST FLOW WILL ENSURE A STEADY STREAM OF MUCH COOLER AND DRIER CANADIAN AIR INTO THE REGION FOR MUCH OF THE PERIOD. ENSEMBLE MEAN H85 TEMPS DIPPING INTO THE 6-8C RANGE SHOULD YIELD AFTERNOON HIGHS A FEW DEGREES BELOW AVERAGE...GENERALLY IN THE UPPER 60S TO MIDDLE 70S UNDER MAINLY CLEAR SKIES PER 1000-500MB MEAN RH VALUES LESS THAN 30 PERCENT FOR MUCH OF THE PERIOD. LAKE BREEZES WILL ALSO BE AN ISSUE EACH AFTERNOON THROUGH AT LEAST SUNDAY GIVEN SLACK LOW LEVEL FLOW (950MB WINDS ONLY 5 T0 10 KNOTS)...SO EXPECT THE POTENTIAL FOR EVEN COOLER TEMPS ALONG THE IMMEDIATE LAKESHORES. OVERNIGHT LOWS WILL BE QUITE COMFORTABLE (COMPARED TO THE RECENT MILD READINGS)...MAINLY IN THE 40S TO LOWER 50S...THOUGH CERTAINLY NOT OUT OF THE QUESTION FOR SOME OF THE COOLER SPOTS (KPLN...THE AU SABLE RIVER VALLEY...ETC.) TO MAKE A RUN AT THE UPPER 30S... ESPECIALLY THURSDAY NIGHT AND PERHAPS AGAIN FRIDAY NIGHT AS GRADIENT RELAXES AND CLEAR SKIES/SUBSIDENCE PROMOTE EXCELLENT RADIATIONAL COOLING. AS FOR PRECIPITATION CHANCES THROUGH SUNDAY...APPEARS THREAT NEGLIGIBLE DESPITE STEEP LOW LEVEL LAPSE RATES OWING TO COOL POOL ALOFT AND POTENTIAL CONVERGENCE FROM LAKE BREEZES...AS MOISTURE SIMPLY LACKING TO PRODUCE ANY SORT OF SIGNIFICANT INSTABILITY. BEYOND SUNDAY...THINGS BEGIN TO CHANGE AS THE OVERALL BLOCKING PATTERN STARTS TO BREAK DOWN. PROGGED PATTERN PER THE GFS/ECMWF/CANADIAN/DGEX SUPPORTS INCREASED CONVECTIVE CHANCES HEADING INTO NEXT WEEK AS PIECES OF PACIFIC ENERGY TOP THE RIDGE AND HEAD TOWARD THE GREAT LAKES. MEANWHILE...PERSISTENT WESTERLY FLOW OUT OF THE ROCKIES WILL INDUCE LEE CYCLOGENESIS OVER THE HIGH PLAINS. ASSOCIATED DEVELOPING WARM FRONT ACROSS THE UPPER MIDWEST/GREAT LAKES WILL PROVIDE A FOCUS FOR MORE WIDESPREAD CONVECTIVE DEVELOPMENT AS MOISTURE/INSTABILITY RETURN AROUND PERIPHERY OF LOW LEVEL RIDGE AXIS SLIDING OFF THE MID ATLANTIC COAST. TIMING OF OVERALL CONVECTIVE POTENTIAL STILL FAR FROM BEING NAILED DOWN BUT DOES APPEAR ADDITION OF CHANCE POPS JUSTIFIED BY TUESDAY AS BOUNDARY LAYER DEW POINTS CREEP BACK INTO THE 50S AND TEMPS REBOUND TO AROUND 80...WITH SUBSEQUENT INCREASE IN MLCAPE TO AROUND 1000J/KG. MODEL GUIDANCE ALSO SEEMS TO BE KEYING IN ON THIS TIMEFRAME...AND PATTERN RECOGNITION (PROVIDED THE H5 HEIGHT PATTERN TURNS OUT AS ADVERTISED) MAKES A CASE FOR MCS POTENTIAL. FOR NOW WILL KEEP THE 4TH OF JULY PRECIPITATION-FREE AS APPEARS ANY ORGANIZED CONVECTION WOULD LIKELY FORCE THE BOUNDARY SUFFICIENTLY FAR SOUTH TO PREVENT ADDITIONAL STORMS...THOUGH WILL HAVE TO WATCH AS PATTERN LOOKS TO UNDERGO YET MORE CHANGES TOWARD THE END OF THE WEEK...WITH DEEP TROUGHING INTO THE GULF OF ALASKA SUPPORTING A RETROGRESSION OF THE OVERALL PATTERN...THUS PULLING MORE PRONOUNCED TROUGHINESS BACK ACROSS THE GREAT LAKES. LAWRENCE && .AVIATION...COLD FRONT WILL SLIDE ACROSS NORTHERN LOWER MI DURING THE REMAINDER OF THE AFTERNOON. THE FRONT HAS ALREADY CLEARED KTVC AND KPLN AND WILL PASS THROUGH KAPN OVER THE NEXT FEW HOURS. THUNDERSTORMS WILL REMAIN IN THE VICINITY OF KAPN UNTIL THE FRONT PASSES THE AIRPORT IN A FEW HOURS. DRIER AIR WILL MOVE INTO NORTHERN LOWER IN THE WAKE OF THIS FRONT FOR THE REMAINDER OF THIS AFTERNOON AND INTO THE EVENING. MAINLY VFR CONDITIONS EXPECTED OUTSIDE OF THUNDERSTORM ACTIVITY. KAS && .APX WATCHES/WARNINGS/ADVISORIES...NONE. &&
