A QUIET NIGHT WEATHERWISE ACROSS NORTHERN MICHIGAN WITH JUST A FEW
HIGH CLOUDS SLIDING INTO THE AREA FROM THE NORTHWEST. LOW PRESSURE
NORTH OF SUPERIOR WILL HELP TO PUSH A FRONT SOUTHWARD TOWARD
NORTHWEST CHIPPEWA COUNTY LATE TONIGHT...WITH A FEW SHOWERS
GETTING CLOSE TO WHITEFISH POINT BY SUNRISE. BECAUSE OF
THIS...WILL ADD A LOW POP TO THIS AREA. OTHERWISE...FEW WEATHER
CONCERNS WITH MAINLY CLEAR SKIES AND COOL TEMPS. LOWS RANGING FROM
THE MID 40S TO THE MID 50S...WITH A FEW COLDER LOCATIONS POSSIBLY
DIPPING INTO THE LOWER 40S.

.NEAR TERM...(THIS EVENING THROUGH TONIGHT)
ISSUED AT 343 PM EDT THU JUL 2 2015

LARGE AREA OF HIGH PRESSURE REMAINS OVER THE GREAT LAKES REGION THIS
AFTERNOON...RESULTING IN PLENTY OF SUNSHINE ACROSS OUR ENTIRE CWA.
UPPER LEVEL TROUGH CONTINUES TO DEPART TO OUR EAST...WITH THE 500 MB
RIDGE AXIS NOW NUDGING INTO THE WRN GREAT LAKES. AREA OF MID CLOUDS
SPILLING OVER THE UPPER RIDGE AXIS AND INTO LAKE SUPERIOR AND
PORTIONS OF UPPER MICHIGAN CONTINUES TO DIMINISH WITH SE PROGRESS.
ONLY OTHER CLOUD COVER TO SPEAK OF IS A FEW AREAS OF FAIR WX CU THAT
HAVE POPPED UP OVER PORTIONS OF INTERIOR ERN UPR MICHIGAN AND IN A
FEW LOCATIONS ACROSS NRN LWR MICHIGAN DRIVEN BY LAKE BREEZE
CONVERGENCE.

FEW AREAS OF CU WILL DISSIPATE BY SUNSET WITH LOSS OF DAYTIME
HEATING. MID CLOUD DROPPING SE INTO ERN UPR MICHIGAN WILL ALSO
CONTINUE TO DIMINISH AS IT HITS DRIER MID LEVEL AIR OVER MICHIGAN.
WE WILL SEE SOME INCREASE IN MID/HIGH CLOUDS VERY LATE TONIGHT INTO
EARLY FRIDAY AS THE SRN TIP OF ENHANCED MOISTURE CLIPS OUR NRN CWA
ASSOCIATED WITH LOW PRESSURE MOVE THRU NRN CANADA. EXPECT ANOTHER
COOL NIGHT ACROSS THE NORTHWOODS...BUT NOT QUITE AS COOL AS LAST

.SHORT TERM...(FRIDAY THROUGH SUNDAY)
ISSUED AT 343 PM EDT THU JUL 2 2015

PATTERN OVERVIEW/FORECAST: STRONG RIDGE REMAINS ALONG THE WEST COAST
OF THE CONUS TODAY WITH TROUGHINESS AND OF COURSE COOLER WEATHER
ACROSS CENTRAL/EASTERN CANADA AND THE GREAT LAKES. WEATHER NIL FOR
NORTHERN MICHIGAN WITH A LARGE EXPANSE OF HIGH PRESSURE DRAPED
ACROSS THE STATE AND THE UPPER MIDWEST. GOING FORWARD THROUGH THE
HOLIDAY WEEKEND AND NEXT WEEK...LONG WAVE RIDGE/TROUGH PATTERN
ACROSS THE CONUS IS EXPECTED TO SLOWLY RETROGRADE WESTWARD IN TIME
ALLOWING SOME WARMER (READ SEASONABLE) AIR TO WORK INTO THE GREAT
LAKES.  LEVEL RIDGE ACROSS THE WEST COAST IS EXPECTED TO WEAKEN AND
RETROGRADE INTO THE PACIFIC BREAK DOWN

FRIDAY/FRIDAY NIGHT...HIGH PRESSURE WILL HOLD THROUGH MUCH OF THE
DAY...ACROSS THE LOWER LAKES ESPECIALLY. MEANWHILE... SHORT WAVE
ENERGY IN SOUTH-CENTRAL CANADA TODAY WILL SKIRT THROUGH ONTARIO...
PUSHING A TRAILING ALTHOUGH WEAKENING COLD FRONT INTO NORTHERN
MICHIGAN LATE FRIDAY AND FRIDAY NIGHT. MOST PRECIP WITH THIS SYSTEM
WILL REMAIN ACROSS ONTARIO. BUT...MOISTURE POOLING AND MODEST
CONVERGENCE ALONG THE FRONT COULD PRODUCE A FEW SHOWERS/THUNDER
FRIDAY AFTERNOON ACROSS EASTERN UPPER MICHIGAN...AND A FEW SHOWERS
SAGGING INTO NRN LOWER MICHIGAN FRIDAY NIGHT AS THE FRONT SAGS
SOUTHWARD. NOT EXPECTING A RAIN OUT BY ANY STRETCH (UNLESS OF COURSE
YOU/RE THE UNLUCKY SPOT THAT ENDS UP UNDER A HEAVY SHOWER)...BUT
THOSE PLANNING OUTSIDE ACTIVITIES FRIDAY NIGHT SHOULD KEEP IN MIND
AT LEAST THE POSSIBILITY FOR SOME RAIN.

SATURDAY AND SATURDAY NIGHT...FRONT LARGELY WASHES OUT ACROSS LOWER
MICHIGAN WITH WEAK LOW LEVEL FLOW AND STRETCHED OUT THETA-E AXIS
SITTING ACROSS NRN LOWER MICHIGAN SATURDAY AFTERNOON. HAS ALL THE
EARMARKS OF SPOTTY HEATING OF THE DAY SHOWERS AND THUNDER ACROSS
PARTS OF NE LOWER MICHIGAN...SIMILAR TO WHAT WE SAW A FEW DAYS
BACK...AND HAVE KEPT THE GOING FORECAST LARGELY INTACT.

SUNDAY...HIGH PRESSURE AND DRY AIR REBUILDS BACK ACROSS THE WESTERN
GREAT LAKES BRINGING US BACK TO QUIET WEATHER TO WRAP UP THE
WEEKEND. INCREASING S/SW FLOW ON SUNDAY WILL BRING SOME WARMER AIR
AND READINGS IN THE UPPER 70S TO LOWER 80S.

&&

.LONG TERM...(SUNDAY NIGHT THROUGH THURSDAY)
ISSUED AT 343 PM EDT THU JUL 2 2015

A NICE STRETCH OF SUMMER WEATHER FOR THE GREAT LAKES THROUGH THE
PERIOD. AT UPPER LEVELS...THE 500MB RIDGE WHICH DEVELOPED OVER THE
GREAT LAKES DURING THE WEEKEND WILL BEGIN TO EXIT EAST ON
MONDAY...WITH NEARLY ZONAL FLOW ALOFT DEVELOPING ACRS THE NRN
THIRD OF THE COUNTRY FOR THE REMAINDER OF THE WORK WEEK. THIS
PATTERN WILL GENERATE YET ANOTHER DAY WITH AFTERNOON TEMPS IN THE
80S ON MONDAY...BEFORE TEMPS FALL TO MORE SEASONAL READINGS IN THE
MID 70S BY MID WEEK. AT THE SURFACE...A STORM SYSTEM ORGANIZING
OVER THE CENTRAL PORTIONS OF THE COUNTRY ON SUNDAY...WILL PUSH
ACROSS THE GREAT LAKES MONDAY NIGHT AND GENERATE A CHANCE OF
SHOWERS INTO TUESDAY. A SECOND PLAINS SYSTEM WILL LIFT INTO THE
GREAT LAKES THURSDAY...GENERATING THE NEXT CHANCE OF RAIN ACROSS
NORTHERN MICHIGAN.
