AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GAYLORD MI
1054 AM EDT SAT AUG 4 2012

.SYNOPSIS...
ISSUED AT 345 AM EDT SAT AUG 4 2012

A WARM FRONT WILL MOVE NORTHWARD INTO NORTHERN MICHIGAN
TODAY...RETURNING HOT AND HUMID WEATHER TO THE AREA. THUNDERSTORMS
ARE LIKELY ACROSS MUCH OF THE STATE TONIGHT AS A COLD FRONT MOVES
THROUGH. SEVERE WEATHER IS NOT OUT OF THE QUESTION WITH DAMAGING
WINDS AND POSSIBLE LARGE HAIL IN THE STRONGER STORMS. FAIR AND
PLEASANT WEATHER IS THEN EXPECTED FOR THE BEGINNING OF NEXT WEEK.

&&

.UPDATE...
ISSUED AT 1054 AM EDT SAT AUG 4 2012

POTENT MID LEVEL WAVE NOW DIGGING SOUTHEASTWARD ACROSS THE NRN
PLAINS...HEADING INTO THE UPPER MIDWEST. NICE COUPLED UPPER JET
STRUCTURE WITH THIS SYSTEM...WITH ONE JET CORE ACROSS NRN ONTARIO/
HUDSON BAY REGION AND A SECOND CORE ROUNDING THE TROUGH ACROSS THE
DAKOTAS/MINNESOTA. MAIN SFC LOW SITUATED UNDER THE UPPER DIVERGENCE
MAX OF THE COUPLED JET...OVER WESTERN ONTARIO. COLD FRONT STRETCHES
DOWN THROUGH THE UPPER-MID MISSISSIPPI RIVER VALLEY TO A SECONDARY
LOW OVER NW MISSOURI. WARM FRONT NOW LIFTING UP THROUGH NRN LOWER
MICHIGAN THIS MORNING WITH DEWPOINTS INCREASING TO THE MID AND
UPPER 60S. SECOND WARM FRONT SITTING ACROSS THE OHIO RIVER VALLEY
WITH ANOTHER SURGE OF LOW LEVEL MOISTURE PRESSING NORTHWARD INTO
FAR SRN LOWER MICHIGAN...EVIDENCED BY EXPANDING CLOUD COVER FROM
OHIO INTO SE LOWER.

MEANWHILE...MULTIPLE CONVECTIVE COMPLEXES IN VARIOUS STAGES
ONGOING IN THE REGION AHEAD OF THE COLD FRONT/STRONG UPPER TROUGH.
NOTHING IMMEDIATELY THREATENING TO NRN MICHIGAN ALTHOUGH STILL
QUITE A BIT OF DEBRIS CLOUD WORKING ACROSS THE FAR WESTERN GREAT
LAKES.

REST OF TODAY AND TONIGHT...COMPLEX...AS NOTED ABOVE. MODEST ELEVATED
MIXED LAYER HAS DEVELOPED OVER NRN MICHIGAN OVERNIGHT...AND 12Z
APX SOUNDING ALREADY UNSTABLE WITH OVER 1000 J/KG MLCAPE...BUT
ALSO CAPPED FOR THE MOMENT. 89/64 SFC PARCEL WOULD BE ENOUGH TO
ERASE CAPPING THIS AFTERNOON...ASSUMING NOTHING ELSE CHANGES.
HOWEVER...GUIDANCE SUGGEST WE SEE SOME SUBTLE MID LEVEL WARMING
TODAY THANKS TO ONGOING WARM ADVECTION...ENOUGH TO KEEP ATMOSPHERE
JUST CAPPED IN THE PRESENCE OF WEAK OR NON-EXISTENT FORCING. OF
COURSE...GIVEN THE WARMTH/HUMIDITY...CANNOT RULE OUT SOMETHING
POPPING UP WHEREVER LOW LEVEL CONVERGENCE IS MAXIMIZED THIS
AFTERNOON AND EARLY EVENING (TERRAIN/MARINE BOUNDARIES...ETC).
THIS WILL KEEP SLIGHT CHANCE POPS GOING WITH SOME MINOR SPATIAL
TWEAKING.

MAIN SHOW STILL LOOKING TO ARRIVE LATER TONIGHT AS OUR COLD FRONT
ADVANCES THROUGH THE REGION. BUT GIVEN THE ABUNDANT CLOUD COVER
OVER WISCONSIN CURRENTLY (HAMPER TO HEATING) STILL UNSURE HOW THIS
WILL UNFOLD YET.

UPDATE ISSUED AT 618 AM EDT SAT AUG 4 2012

FCST GOING AS PLANNED THUS FAR OUTSIDE OF THE LACK OF EVEN A LONE
SHOWER DEVELOPING IN THE NORTHWARD ADVANCING AXIS OF HIGHER
THETA-E...NOW MOVING NORTH OF EASTERN UPPER/DRUMMOND ISLAND.HAVE
TAKEN OUT ANY MENTION OF AN EARLY MORNING RAIN SHOWER. THIS DRY
TREND ON ITS WAY INTO MOST OF THE DAY...UNTIL SOME ISOLATED
ACTIVITY TRIES TO DEVELOP BY LATE AFTERNOON/EARLY EVENING.
CONVECTIVE CLOUD DEBRIS CONTINUES TO PUSH TOWARD NRN MICHIGAN BUT
IS THINNING IN THE PROCESS AS CLOUD TOPS WARM FROM CONVECTION
IN WISCONSIN OUTRUNNING ITS UPPER SUPPORT. BELIEVE THAT SUNSHINE
WILL APPEAR LATER THIS MORNING FOR A WARM UP INTO VERY WARM
TEMPERATURES...PER FORECAST IN THE 80S/LOW 90S.

&&

.SHORT TERM...(TODAY THROUGH TONIGHT)
ISSUED AT 345 AM EDT SAT AUG 4 2012

UPPER LEVEL HEIGHTS HAVE BEEN SLOWLY RISING THROUGH THE
NIGHT...WHICH GRADUALLY DAMPENED OUT A MID LEVEL TROUGH THAT IS NOW
WORKING EAST OF NRN MICHIGAN WITH STRONG DRYING ALOFT AND NOTHING IN
THE FORM OF PRECIPITATION. THIS DESPITE THE SLOW NORTHWARD TREK OF A
WARM FRONT DRAPED ACROSS THE SW HALF OF THE CWA...AS LOW LEVEL WINDS
ARE GRADUALLY TURNING MORE SOUTHERLY WITH TIME. AN AXIS OF DEEPER
LOW LEVEL MOISTURE/THETA-E AIR ASSOCIATED ALONG THE FRONT IS LIFTING
INTO EASTERN UPPER AND NE LOWER...ALTHOUGH THIS IS RATHER DIFFUSE.
BASICALLY THE ENTIRE CWA IS UNDER WEAK H8-H7 WARM ADVECTION.
THERE ARE SIGNALS OF MAYBE SOME EVEN WEAKER MID LEVEL IMPULSES
DRIFTING OUR WAY...AND A FEW SHOWERS ARE POSSIBLE IN THE NE HALF
OF THE CWA INTO DAYBREAK...ESPECIALLY DOWNWIND OF THE WARMER GREAT
LAKES.

UPSTREAM...A LONG LINE OF SHOWERS AND STORMS WITH EMBEDDED BOWING
SEGMENTS ARE CROSSING INTO WISCONSIN. THIS PRECIPITATION WAS BEING
FORCED BY A RATHER IMPRESSIVE MID LEVEL SHORTWAVE IN SRN MANITOBA
AND THE DAKOTAS...AHEAD OF A COLD FRONT AND TRIPLE POINT PUNCHING
INTO WISCONSIN. THIS MAY VERY WELL BE A LOOK AT WHAT WILL BE ROLLING
THROUGH OUR NECK OF THE WOODS LATER TONIGHT. THIS PRECIPITATION IS
NO THREAT TO ARRIVE HERE BEFORE DYING AS IT OUTRUNS THE UPPER
SUPPORT...BUT WE MAY HAVE TO DEAL WITH SOME MID/UPPER LEVEL
CONVECTIVE DEBRIS CLOUD. BEHIND THE COLD FRONT...BRISK NW WINDS WERE
RAPIDLY USHERING IN DRIER AND COOLER AIR.

TODAY AND TONIGHT...OUTSIDE OF SOME BRIEF UPPER LEVEL CLOUD...THE
DAY WILL BE CHARACTERIZED AS "PREPPING" THE ATMOSPHERE FOR THE
EASTWARD ADVANCING IMPRESSIVE UPPER WAVE AND SFC COLD FRONT. AS
THE UPPER WAVE AND SFC LOWS LIFT INTO ONTARIO THROUGH
TONIGHT...THE WINDS THROUGHOUT THE COLUMN BECOME RATHER
UNIDIRECTIONAL OUT OF THE SW INTO TONIGHT AND INCREASE AT ALL
LEVELS THROUGH 500MB. THIS WILL ALLOW THE SFC/ELEVATED WARM FRONTS
TO LIFT THROUGH ALL OF NRN MICHIGAN RESULTING IN A VERY WARM DAY.
WITH UPPER LEVEL DEBRIS CLOUDS ERODING THIS MORNING...THE SUN IS
EXPECTED TO COME OUT WHILE ADVECTING IN SFC TDS IN THE MIDDLE 60S
TO LOW 70S. THIS WILL BRING ABOUT A REAL MUGGY DAY/EVENING. HIGHS
WILL REACH THE MID 80S TO LOWER 90S. LOW LEVEL WINDS ARE SEEMINGLY
TOO STRONG FOR LAKE BREEZES...BUT RELATIVELY GREATER HEATING OVER
INLAND AREAS WILL RESULT IN A LOWER PRESSURE THERE...WHICH HELPS
THE DESIRE FOR WINDS TO TURN MORE ONSHORE. THIS RESULTS IN
LOCALIZED INCREASES IN WIND CONVERGENCE IN INTERIOR SECTION OF NRN
MICHIGAN. ONLY WEAK IMPULSES ARE EXPECTED TO ROLL ON IN
TODAY...AND DESPITE THE ATMOSPHERE'S INSTABILITY RISING INTO THE
1500 J/KG AREA...THE LACK OF AN ASSISTING FORCING MECHANISM
(OUTSIDE OF UPSLOPE FLOW AND WEAK CONVERGENCE) REALLY DIMINISHES
THE CHANCE FOR SEEING RAINFALL TODAY. THERE IS NO APPARENT CAP
OUTSIDE OF SOME SOUNDING ANALYZED 10MBS OR LESS LOW LEVEL CAPPING
DUE TO WARMING. PERHAPS A WIGGLE IN THE FLOW AND TERRAIN INDUCED
LIFT COULD SPARK OFF A SHOWER/STORM OR TWO. WILL LOWER POPS TO
JUST ISOLATED SHOWERS/POSSIBLE STORM ON AND DOWNWIND OF THE HIGHER
TERRAIN OF INTERIOR NRN LOWER. ANY CELLS WOULD DRIFT OFF INTO
EASTERN SECTIONS OF CHIP/MACK COUNTIES OF EASTERN UPPER. BELIEVE
THAT THIS ACTIVITY WILL INCREASE IN SOME DEGREE WITH THE APPROACH
OF THE UPPER WAVE TONIGHT AND FALLING HEIGHTS LATE IN THE EVENING
AND ESPECIALLY OVERNIGHT. RIGHT ENTRANCE REGION OF AN UPPER JET
AND NICE DIVERGENCE ALOFT WILL PROVIDE THE NECESSARY DYNAMICS
ALOFT TO HELP CONVECTION FIRE IN THE INITIAL AXIS OF HIGHER
THETA-E AND ALONG THE SFC BASED COLD FRONT WHICH WILL BE MOVING
INTO NW LOWER/WESTERN CHIP/MACK AS EARLY AS EARLY TO MID EVENING.
A MID LEVEL JET WILL BE PRESENT OUT OVER WISCONSIN AND UPPER
MICHIGAN...AND 0-6KM BULK SHEAR RISES INTO THE 30-35KT RANGE EARLY
ON. HOWEVER...WITH THE SFC LOW LIFTING NORTH AND PULLING MORE OF
THE STRONGER LOW LEVEL CONVERGENCE AND DYNAMICS AWAY...STRENGTH OF
ANY STORMS WILL LIKELY WEAKEN A TOUCH THROUGH THE NIGHT...DESPITE
INCREASING SHEAR WITH ARRIVAL OF THE STRONGER FLOW/UPPER WAVE.
INSTABILITY WANES AS WELL. THE EXCEPTION HERE IS FOR A SECONDARY
BATCH OF INCREASED MOISTURE LIFTING INTO NE LOWER FROM THE MID
MISSISSIPPI VALLEY AS THE FRONT ARRIVES. THERE IS ALSO A SUGGESTED
SECONDARY WAVE OF SFC LOW PRESSURE DEVELOPING HERE. COULD SEE THE
UPTICK OR MAINTENANCE OF COVERAGE/INTENSITY OF STORMS THERE. THIS
SCENARIO IS SOMEWHAT SIMILAR TO WHAT HAS OCCURRED FROM THE DAKOTAS
THROUGH WISCONSIN TONIGHT...STORMS WEAKENING WITH TIME. GONNA
OBVIOUSLY STILL NEED TO WATCH THE DEVELOPMENT OF STORMS AND THE
POTENTIAL FOR SEVERE CELLS...BUT WOULD HAVE TO SAY THAT MAYBE THIS
FORECASTER IS JUST SLIGHTLY LESS EXCITED ABOUT THE COVERAGE OF
SEVERE WEATHER. WE WILL SEE A LINE OF STORMS DEVELOP WITH EMBEDDED
BOW ECHOES FOR A DAMAGING WIND THREAT IN SUCH DEEP SW FLOW. LARGE
HAIL THREAT MAY BE DIMINISHING TO SOME DEGREE FROM THE ABOVE
SCENARIO...AND WITH THE TIME OF NIGHT THE FRONT ARRIVES.
HOWEVER...WILL STILL HAVE TO KEEP A MENTION IN THE HWOAPX...AS WELL
AS AN ISOLATED TORNADO THREAT AT THE TRIPLE POINT OF THE SECONDARY
SFC LOW LIFTING INTO PORTIONS OF NE LOWER....ESPECIALLY NEAR SAG
BAY. DID BEGIN A MORE DETAILED TIMING IN THE ARRIVAL OF SEVERE
THREATS...WITH THE BEST SHOT BEING LATE EVENING THROUGH THE
OVERNIGHT HOURS. FOLKS IN THE WEST WILL FEEL SOME DRIER AND COOLER
AIR BY DAYBREAK AS THE FRONT SHOULD BE BISECTING THE REGION.

.LONG TERM...(SUNDAY THROUGH FRIDAY)
ISSUED AT 345 AM EDT SAT AUG 4 2012

EXTENDED MODELS ARE IN GOOD AGREEMENT THAT THERE WILL BE UPPER LEVEL
RIDGING CENTERED ACROSS THE FOUR CORNERS REGION THROUGH MUCH OF NEXT
WEEK. THIS RIDGE EXTENDS NORTHWARD INTO WESTERN CANADA WHICH RESULTS
IN DOWNSTREAM TROUGHING ACROSS EASTERN CANADA INTO THE WESTERN GREAT
LAKES REGION. SO EXPECT SEASONABLE TEMPERATURES ALONG WITH PERIODIC
CHANCES OF SHOWERS AND THUNDERSTORMS THROUGH THE WEEK. THE MAIN LONG
TERM FORECAST CONCERNS REVOLVE AROUND POPS PRETTY MUCH TROUGH THE
EXTENDED PERIOD.

SUNDAY...THE SURFACE COLD FRONT WILL CONTINUE TO MOVE ACROSS THE
REGION IN THE MORNING (CHANCE POPS ACROSS NORTHEAST LOWER TO START
THE DAY). BEHIND THIS FRONT THERE IS RESPECTABLE COLD AIR ADVECTION
THROUGH THE DAY. 850 MB TEMPERATURES DROP OFF TO BETWEEN PLUS 7 AND
10 C BY 00Z MONDAY. SO WITH THE LAKES AS WARM AS THEY ARE...OVER
LAKE INSTABILITY WILL INCREASE TO THE POINT WHERE WE COULD SEE SOME
LIGHT SHOWER ACTIVITY DEVELOPING OFF OF LAKES SUPERIOR AND MICHIGAN.
TEMPERATURES SHOULD TOP OUT IN THE LOWER 70S TO THE LOWER 80S EARLY
ON...AND LIKELY FALL OFF DURING THE AFTERNOON HOURS.

SUNDAY NIGHT THROUGH MONDAY NIGHT...EXPECTING A LULL IN THE ACTION
AS SURFACE HIGH PRESSURE RIDGES IN FROM THE SOUTH. SO WITH CLEARING
SKIES AND LIGHT WINDS...GOOD RADIATIONAL COOLING CONDITIONS ON TAP
FOR SUNDAY NIGHT. THEREFORE...LOWERED MINS INTO THE MIDDLE 40S TO
THE MIDDLE 50S. IN ADDITION...RAISED HIGHS ON MONDAY INTO THE UPPER
70S TO MIDDLE 80S AS 850 MB TEMPERATURES QUICKLY MODERATE INTO THE
PLUS 14 C OR SO RANGE. NOT AS COOL MONDAY NIGHT AS THE SURFACE
PRESSURE GRADIENT PICKS UP A BIT ALONG WITH INCREASING THETA-E
RIDGING. LOWS IN THE UPPER 50S TO MIDDLE 60S.

TUESDAY...A WEAK UPPER LEVEL TROUGH/SURFACE COLD FRONT DROPS DOWN
THROUGH THE NORTHWEST FLOW ALOFT. MOISTURE CROSS SECTIONS LOOK
MARGINAL HOWEVER...BUT WITH A BIT OF FORCING FROM UPSTREAM
WAVE...COULD SEE SOME SCATTERED SHOWER AND THUNDERSTORM ACTIVITY.
HIGHS RANGING FROM THE MIDDLE 70S TO LOWER 80S.

WEDNESDAY THROUGH FRIDAY...EXTENDED MODELS ARE IN FAIR AGREEMENT IN
FOLDING OVER AN OMEGA BLOCK RIDGE ACROSS CENTRAL CANADA...SENDING AN
UPPER LEVEL TROUGH INTO THE GREAT LAKES REGION. CONFIDENCE OF THIS
SCENARIO UNFOLDING IS ON THE LOWER SIDE SO WILL ONLY HAVE SLIGHT TO
LOW CHANCE POPS FOR THURSDAY INTO FRIDAY. HIGH TEMPERATURES
REMAINING IN THE SEASONAL MIDDLE 70S TO LOWER 80S WITH LOWS IN THE
UPPER 50S TO LOWER 60S.

&&

.AVIATION...(FOR THE 12Z TAFS THROUGH 12Z SUNDAY MORNING)
ISSUED AT 618 AM EDT SAT AUG 4 2012

A WARM FRONT WILL LIFT THROUGH NRN MICHIGAN TODAY...ALLOWING SE
WINDS TO WRAP AROUND TO OUT OF THE SSW. SOME GUSTS APPROACHING 20
KTS IN SPOTS. ISOLATED SHOWERS ARE EXPECTED TO DEVELOP LATE THIS
AFTERNOON AND EARLY THIS EVENING...CLOSE TO AFFECTING APN...BUT
EAST OF THE OTHER AIRPORTS. THE ACTION WILL PICK UP SUBSTANTIALLY
LATE THIS EVENING IN NW LOWER AND OVERNIGHT INTO NE LOWER. THIS
DUE TO A COLD FRONT THAT CROSSES THE REGION. SHOWERS AND STORMS
WILL ROLL THROUGH MAINLY OVERNIGHT...WITH BOW ECHOES EMBEDDED
WITHIN THE SWATH OF PRECIPITATION. DAMAGING WINDS TO 70 MPH WILL
BE LOCATED IN SPOTS ALONG THIS LINE...WITH LARGE HAIL...BRIEF
HEAVY DOWNPOURS EXPECTED IN BRIEF MVFR/IFR CONDITIONS. WILL START
THE TIMING ACROSS NW LOWER CLOSE TO MIDNIGHT...WITH THE ACTION
ROLLING INTO APN OVERNIGHT. WINDS WILL ABRUPTLY SWITCH TO OUT OF
THE WNW LATE.

&&

.MARINE...
ISSUED AT 345 AM EDT SAT AUG 4 2012

VERY WARM WATER THIS TIME OF YEAR HAS LED TO A SOLID 10 TO 20 KTS
OF SE WINDS OUT OVER THE LAKES EARLY THIS MORNING...WITH VARIOUS
ADVISORY WIND GUSTS OVER THE NEARSHORE WATERS. DEVELOPING LOW
PRESSURE WORKING INTO SW ONTARIO WILL LIFT ENE THROUGH ONTARIO
TODAY AND TONIGHT. THIS WILL DRAG A COLD FRONT ACROSS THE
NEARSHORE WATERS LATE TONIGHT INTO EARLY SUNDAY. THE PRESSURE
GRADIENT OUT AHEAD OF THIS FRONT WILL TIGHTEN UP TODAY...ALLOWING
SMALL CRAFT ADVISORY WINDS. AFTER A LULL IN THE ACTION SURROUND
THE COLD FRONT...WINDS VEER ABRUPTLY SHIFT TO OUT OF THE WEST AND
NW...AND INCREASE AGAIN TO ADVISORY LEVELS SUNDAY THROUGH SUNDAY
NIGHT. THE PRESSURE GRADIENT REMAINS TIGHT ENOUGH FOR 10 TO 20
KNOTS MONDAY. FOR LATER NEXT WORK WEEK...WINDS ARE EXPECTED TO BE
BELOW ADVISORY LEVELS.
