AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GAYLORD MI
120 AM EDT TUE JUL 12 2011

.SYNOPSIS.../ISSUED AT 238 PM/

HAZY WARM AND HUMID CONDITIONS WILL COME TO AN END TONIGHT...AS A
COOL FRONT DROPS THROUGH THE GREAT LAKES. FAIRLY STRONG HIGH
PRESSURE WILL SLOWLY SLIDE FROM LAKE WINNIPEG TUESDAY INTO THE GREAT
LAKES WEDNESDAY...AND REMAIN OVERHEAD INTO THURSDAY. THIS WILL
RESULT A STRETCH OF PLEASANT WEATHER WITH MUCH LESS HUMIDITY.
WEDNESDAY COULD BE PARTICULARLY COOL...WITH HIGHS STRUGGLING TO
REACH 70 DEGREES IN SPOTS. THEREAFTER...A GRADUAL WARMING TREND WILL
OCCUR. THE NEXT CHANCE FOR A SHOWER OR THUNDERSTORM IS EXPECTED
THURSDAY NIGHT INTO FRIDAY.

&&

.SHORT TERM.../ISSUED AT 1000 PM/...OVERNIGHT

HIGH PRESSURE AND DRIER AIR CONTINUES TO GRADUALLY NUDGE EASTWARD
INTO THE FAR WRN GREAT LAKES REGION LATE THIS EVENING AS LAST
VESTIGES OF A COOL FRONT EXITS SE LWR MICHIGAN. A FEW SHOWERS TRIED
TO POP ALONG THE LAKE BREEZE CONVERGENCE BOUNDARY IN ERN UPR
MICHIGAN EARLIER IN THE EVENING...BUT ONLY LAST ABOUT 4 FRAMES OF
THE 88D. SOME RESIDUAL LOW CLOUDS ARE MOVING THRU NRN LWR MICHIGAN
ATTM...AND THE SRN TIP OF A SCT/BKN AREA OF LOW STATUS IS CLIPPING
FAR ERN UPR MICHIGAN AS WELL. HAVE MADE SOME UPWARD MODIFICATIONS TO
CLOUD COVER FOR THE NEXT FEW HOURS...WITH A GENERAL CLEARING TRENDS
VERY LATE TONIGHT. DWPTS REMAIN RATHER HIGH AS WELL...AND WITH CLEAR
SKIES...LIGHT WINDS AND RECENT RAINFALL FOR SOME OF OUR CWA...WILL
NEED TO ADD SOME MENTION OF PATCHY FOG OVERNIGHT.

&&

.LONG TERM.../ISSUED AT 238 PM/...TUESDAY AND BEYOND

TUE INTO THU: NICE BREAK FROM THE HEAT/HUMIDITY ON THE WAY INTO
MIDWEEK AS ELONGATED LOW LEVEL RIDGING BUILDS SOUTH INTO THE GREAT
LAKES FROM CANADA...IN THE WAKE OF TONIGHT'S FRONTAL PASSAGE. FEW
CONCERNS THROUGH THE PERIOD...THOUGH WILL NEED TO WATCH OVERALL
EVOLUTION OF CLOUD COVER BOTH TUE AND WED. WITH TREND TOWARD
SLIGHTLY SLOWER ONSET OF COLD ADVECTION TUE AFTERNOON...CAN FORESEE
SOME CU FIRING OFF ACROSS MAINLY THE SOUTHEAST HALF OF THE CWA WHERE
BETTER LOW LEVEL MOISTURE PROGGED TO LINGER...WITH LIKELIHOOD OF
DIURNAL CU INCREASING RAPIDLY ON WED BENEATH COLD POOL ALOFT. IN
FACT...PER UPSTREAM OBS TODAY BENEATH OUR INCOMING AIRMASS...WILL
TREND THINGS TOWARD MOSTLY CLOUDY INLAND SPOTS WED AFTERNOON AS
DIURNAL CU RESPONSE SPREADS OUT INTO STRATOCU DECK BENEATH RATHER
STOUT LOW LEVEL INVERSION. IN FACT...WOULD NOT BE COMPLETELY SHOCKED
TO SEE A ROGUE SPRINKLE/LIGHT SHOWER DEVELOP BENEATH THE LOW LEVEL
COLD POOL...BUT CERTAINLY NOTHING WORTH MENTIONING. HIGHS TO TAKE A
TUMBLE BY WED...WITH READINGS SQUARELY IN THE LOW/MID 70S...AND
PERHAPS STUCK IN THE 60S HIGH SPOTS...ESPECIALLY SHOULD CLOUD COVER
END UP A LITTLE THICK. CHILLY NIGHTS WITH CLEAR SKIES/LIGHT WINDS
AND INFLUX OF MUCH DRIER AIR...WITH THE USUAL COOL SPOTS LIKELY TO
DIP INTO THE 40S. ENJOY!

LATER PERIODS (THU NIGHT THROUGH MON)...CLASSIC SUMMERTIME MID-CONUS
PATTERN FORECAST THROUGH THE EXTENDED PORTIONS OF THE FORECAST...
FEATURING FURTHER AMPLIFICATION OF STRONG HEAT RIDGE THROUGH MUCH OF
THE MIDWEST RIGHT ON THROUGH MON. IN TYPICAL FASHION...HOWEVER...
CORE OF HIGHEST HEAT NOT LIKELY TO MAKE IT INTO NORTHERN MICHIGAN
THANKS TO RESIDUAL WEAK DOWNSTREAM TROUGHING INTO THE NORTHEAST
CONUS...THOUGH CERTAINLY COULD SEE A DAY OR TWO OF VERY WARM
CONDITIONS TOWARD THE TAIL END OF THE FORECAST. OF BIGGER CONCERN IS
POTENTIAL FOR CONVECTION...AS PROGGED UPPER PATTERN HIGHLY FAVORS
MUCH OF NORTHERN MICHIGAN SQUARELY IN THE MCS TRACK. OBVIOUSLY
DIFFICULT IF NOT IMPOSSIBLE TO TIME POTENTIAL FOR MCS FEATURES THIS
FAR OUT...BUT ECMWF THE PAST FEW DAYS HAS REMAINED REMARKABLY
CONSISTENT REGARDING INITIAL POTENTIAL ARRIVING THU NIGHT/FRI. WILL
MAINTAIN SMALL POPS FOR THIS PERIOD...BUT THEREAFTER...JUST TOO MUCH
UNCERTAINTY TO CLUTTER UP THE FORECAST WITH VARIOUS OTHER PRECIP
CHANCES...THOUGH SOME POTENTIAL EXISTS LATER SUN AND/OR MON...THOUGH
BY THEN...BUILDING HEIGHTS MAY FAVOR MORE OF AN MCS TRACK THROUGH
SOUTHERN CANADA DOWN THROUGH THE NORTHEAST CONUS. TEMPS WILL
STEADILY GAIN A FEW DEGREES EACH DAY...LIKELY ENDING UP WELL INTO
THE 80S (LOWER 90S?) TOWARD SUN/MON PENDING NO SURPRISE CLOUDS OR
PRECIP.

&&

LOW WAVES...ALONG WITH MORE SEASONABLE TEMPERATURES AND MUCH LOWER
