AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GAYLORD MI
429 PM EDT WED JUN 9 2010

.SYNOPSIS.../ISSUED AT 401 PM/

A RATHER STRONG UPPER LEVEL DISTURBANCE CROSSING FAR NORTHERN LAKE
SUPERIOR WILL KICK OFF A SMATTERING OF SHOWERS AND THUNDERSTORMS
HEADING INTO THE EVENING HOURS. IN ITS WAKE...DRIER AIR WILL ARRIVE
ON THURSDAY...YIELDING A RATHER PLEASANT DAY.

THE WEATHER PATTERN WILL TURN MORE ACTIVE BETWEEN FRIDAY AND
SUNDAY...AS THE NEXT LOW PRESSURE SYSTEM AND WARM FRONT LIFT INTO
THE GREAT LAKES. THIS WILL BRING ADDITIONAL CHANCES FOR SHOWERS AND
STORMS.

HIGH PRESSURE IS EXPECTED TO ARRIVE FOR THE START OF NEXT WORK
WEEK...BRINGING A RENEWED PUSH OF DRIER AND COOLER WEATHER.

LAWRENCE

&&

.SHORT TERM.../ISSUED AT 401 PM/...TONIGHT

LOW PRESSURE NORTH OF LAKE SUPERIOR WITH THE 500 MB LOW IS
CONTINUING TO DRAG A COLD FRONT THROUGH UPPER MICHIGAN THIS
AFTERNOON AND EARLY THIS EVENING. THE THUNDERSTORMS ASSOCIATED WITH
THIS LOW WILL PUSH INTO ONTARIO OVER THE NEXT COUPLE OF HOURS. WITH
THE MAIN 500 MB VORT PUSHING THROUGH E UPPER, THERE WILL BE A FEW
SHOWERS IN N LOWER, MAINLY EAST OF I-75 AND NORTH OF M-72. IT
DOESN'T LOOK LIKE THE SHOWERS AND POSSIBLE THUNDER WILL BE A PROBLEM
IN N LOWER AS THE BEST DYNAMICS WITH THIS SYSTEM ARE CLOSER TO THE
LOW CENTER. THE LFQ OF THE 500 MB JET IS IN THE VCNTY OF THE 500 MB
COLD POOL AND ITS 500 MB DIFLUENCE AXIS. THIS FEATURE LOOKS TO BE
EAST OF THE REGION, AFTER 06Z, SO AM EXPECTING FROM THAT AS WE GET
PAST THE HEAT OF THE DAY, LOSING THE INSTABILITY, AND THE JET MAX
GOES EAST AFTER 00Z THAT SHOWERS WILL TAPER OFF.

JSL

&&

.LONG TERM.../ISSUED AT 401 PM/...THURSDAY AND BEYOND

MORE CHANCES FOR STILL NEEDED RAINFALL OVER THE NEXT FEW DAYS
(ALTHOUGH SOUTHERN COUNTIES HAVE HAD THEIR FILL LATELY). IN THE
MEANTIME...HIGH PRESSURE WILL BRING A DRY PERIOD FOR THURSDAY AND
THURSDAY NIGHT. PIECES OF ENERGY FROM LONG WAVE TROUGH EVIDENT
ACROSS THE PACIFIC NORTHWEST ON WATER VAPOR LOOP LIFTS NORTHEAST
TOWARD THE GREAT LAKES REGION...BRINGING A FEW CHANCES FOR SHOWERS
AND POSSIBLE THUNDER FRIDAY THROUGH MONDAY. THE MAIN LONG TERM
FORECAST CONCERNS REVOLVE AROUND POPS AND THE POTENTIAL FOR THUNDER.

THURSDAY...SHORT WAVE RIDGING ALOFT AND AT THE SURFACE BUILD INTO
THE REGION FROM THE WEST. MEAN 1000-500 MB RH 40 TO 50 PERCENT SO
PARTLY CLOUDY SKIES EXPECTED. HIGHS RANGING FROM THE MIDDLE 60S
NORTH TO THE LOWER 70S SOUTH.

THURSDAY NIGHT...INCREASING MOISTURE OUT AHEAD OF THE FIRST PIECE OF
ENERGY LEADING TO INCREASING AND THICKENING CLOUDS OVERNIGHT (MEAN
1000-500 MB RH 65 TO 75 PERCENT BY 12Z FRI). LOWS RANGING FROM THE
MIDDLE 40S TO LOWER 50S.

FRIDAY AND FRIDAY NIGHT...SURFACE LOW PRESSURE EMERGES OUT OF THE
PLAINS AND HEADS TOWARD THE REGION FROM THE SOUTHWEST. WARM
ADVECTION/ISENTROPIC ASCENT (I300) OUT AHEAD OF THIS SYSTEM
INCREASES. THETA RIDGE BUILDS IN AS WELL. THEREFORE...HAVE UPPED
POPS TO LIKELY FOR SHOWERS AND THE CHANCE FOR THUNDER (ITS A CLOSE
CALL BUT IT LOOKS LIKE WE WILL REMAIN STABLE WITH THE WARM FRONT
STILL TO OUR SOUTH). HIGHS RANGING FROM THE MIDDLE 60S TO MIDDLE
70S. LOWS IN THE 50S TO LOWER 60S.

SATURDAY AND SUNDAY...THE POSITION OF SURFACE WARM FRONT IS STILL
THE TOUGHEST THING TO PIN DOWN. THIS LOCATION WILL DETERMINE THE
AMOUNT OF INSTABILITY AND THUNDER. OTHERWISE...WEAK IMPULSES OF
ENERGY MOVING THROUGH THE FLOW SHOULD LEAD TO CONTINUED PERIODS OF
SHOWERS. HIGHS MAINLY IN THE 70S WITH LOWS IN THE 50S TO LOWER 60S.

SUNDAY NIGHT THROUGH WEDNESDAY...A SURFACE COLD FRONT MOVES THROUGH
BY SUNDAY NIGHT WITH A NORTHERN STREAM TROUGH MOVING THROUGH ON
MONDAY. THEREFORE WILL CONTINUE WITH LOW CHANCE FOR SHOWERS ON
MONDAY. A RIDGE THEN BUILDS IN FOR TUESDAY WHICH SHOULD HOLD INTO
WEDNESDAY BRINGING PRECIPITATION FREE WEATHER. HIGHS AGAIN MAINLY IN
THE 70S WITH LOWS IN THE UPPER 40S AND 50S.

SULLIVAN

.MARINE.../ISSUED AT 401 PM/

SCATTERED SHOWERS/THUNDERSTORMS THROUGH THIS EVENING ACROSS NORTHERN
MARINE ZONES AS A WEAK UPPER WAVE PASSES OVER UPPER MICHIGAN. EXPECT
DRY CONDITIONS THURSDAY/THURSDAY NIGHT AS HIGH PRESSURE BUILDS INTO
THE REGION. MORE CHANCES FOR SHOWERS AND POSSIBLE THUNDERSTORMS
FRIDAY INTO THE WEEKEND AS A WEAK AREA OF LOW PRESSURE AND AN
ASSOCIATED WARM FRONT APPROACHES FROM THE SOUTHWEST. WINDS/WAVES
EXPECTED TO REMAIN BELOW SCA LEVEL THROUGH FRIDAY MORNING.
INCREASING SOUTHEAST WINDS MAY REQUIRE SCA FOR PORTIONS OF LAKE
HURON AND SUPERIOR LATER FRIDAY INTO FRIDAY NIGHT.

AJS

&&

.AVIATION.../ISSUED AT 129 PM/...VALID FOR 18Z TAFS

APPROACHING UPPER WAVE EXPECTED TO FIRE OFF A SMATTERING OF
SHOWERS AND THUNDERSTORMS NEAR THE TERMINAL SITES HEADING THROUGH
THE AFTERNOON AND EARLY EVENING HOURS...THOUGH OVERALL CONDITIONS
WILL HOLD VFR (LOCALLY LOWER OF COURSE). SMALL HAIL/GUSTY WINDS
ARE POSSIBLE WITH ANY STRONGER STORMS...BUT WILL HOLD WITH CB
MENTION GIVEN THIS IS A VERY SHORT TERM ISSUE (I.E. AMENDABLE
CONDITIONS). OTHERWISE...APPEARS SOME LOWER CLOUDS WILL SETTLE
BACK INTO THE AREA LATE TONIGHT...MOST LIKELY TO AFFECT KPLN AND
KAPN WHERE STRONGEST COOLING ALOFT TAKES PLACE...WITH CEILINGS
DIPPING INTO MVFR RANGE. A SLOW LIFTING OF CEILINGS EXPECTED
THROUGH THE MORNING HOURS OF THURSDAY.
