AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GAYLORD MI
1042 PM EDT THU JUN 7 2007

.UPDATE...DEEP LOW PRESSURE SYSTEM AND ASSOCIATED MID LEVEL WAVE
MOVING QUICKLY INTO SRN ONTARIO THIS EVENING...COLD FRONT EXTENDING
DOWN THROUGH NW WISCONSIN AS OF 02Z. DRYLINE OUT AHEAD OF THE FRONT
ROUGHLY ACROSS NORTH CENTRAL WISCONSIN...AND SOME RENEWED CONVECTION
ALONG THE DRYLINE HEADING NE TOWARD CENTRAL UPPER MICHIGAN. FURTHER
SOUTH...SCT LINE OF CONVECTION ACROSS SE WISCONSIN INTO ILLINOIS
ALONG LEADING EDGE OF MID LEVEL COOLING...HEADING NE TOWARD NRN
LOWER MICHIGAN ATTM.

00Z APX SOUNDING TELLS THE STORY THUS FAR. MLCAPE RUNNING AROUND 600
J/KG...BUT A STRONG CAP IN PLACE JUST ABOVE 750 MB YIELDING NEARLY
170 J/KG OF CONVECTIVE INHIBITION. COMBINED WITH WEAK LOW LEVEL
CONVERGENCE WELL AHEAD OF THE FRONT...EARLIER CONVECTION ACROSS
WISCONSIN AS WELL AS THIN LINE OF SHOWERS/THUNDER THAT MOVED THROUGH
NRN MICHIGAN PRETTY MUCH DWINDLED PRESSING INTO THE CAPPED
ENVIRONMENT. SO UPSTREAM CONVECTION HAS NOT DEVELOPED THIS EVENING
AS ANTICIPATED. HOWEVER...STILL IN A WAIT AND SEE MODE AT THIS
JUNCTURE AS MID LEVEL COOLING PROCEEDS OVERNIGHT (ERODING THE CAP)
AND UPSTREAM FRONT SWINGS INTO THE REGION LATE. ALTHOUGH WE ARE
OBVIOUSLY PAST PEAK HEATING...STILL A DECENT MIXED LAYER AND STRONG
WINDS ALOFT TO TAP INTO IF WE DO GET STORMS TO DEVELOP AND MOVE INTO
THE REGION. BUT HAVE TONED DOWN THE SEVERE WEATHER THREAT IN THE
HAZARDOUS WEATHER OUTLOOK/SPECIAL WEATHER STATEMENT BASED ON THE
TRENDS AND WILL MAKE SOME POP ADJUSTMENTS TO THE GRIDS/ZONE
FORECASTS.

.AVIATION...ISSUED AT 818 PM.

STRONG LOW PRESSURE SYSTEM CENTERED NEAR DULUTH THIS EVENING WITH A
COLD FRONT STRETCHING DOWN THROUGH NW WISCONSIN. WELL AHEAD OF THE
FRONT...INITIAL LINE OF WDLY SCT SHOWERS/ISOLATED THUNDER WILL
IMPACT THE PLN/APN TAF SITES THROUGH 01Z. SCT THUNDERSTORMS NOW OVER
EASTERN WISCONSIN EXPECTED TO MOVE THROUGH NRN LOWER MICHIGAN AFTER
02Z AT TVC/PLN AND APN AFTER 04Z. HOWEVER...OVERALL EVOLUTION AND
COVERAGE OF THUNDERSTORMS REMAIN IN QUESTION. BUT WITH STRONG WINDS
PRESENT ALOFT ANY THUNDERSTORMS OVERNIGHT HAVE THE POTENTIAL OF
PRODUCING VERY STRONG WINDS AT THE SURFACE AND LARGE HAIL. COLD
FRONT PASSES THROUGH NRN LOWER MICHIGAN BETWEEN 12Z AND 16Z FRIDAY
MORNING WITH A WIND SHIFT INTO THE NORTHWEST. THIS WILL BRING AN END
TO THE SHOWER/THUNDERSTORM THREAT ACROSS NRN MICHIGAN...BUT FOLLOWED
BY VFR CIGS FROM MIDDAY ONWARD AS COOLER AIR MOVES INTO THE REGION.

ADAM

.PREV DISCUSSION...ISSUED AT 324 PM.

...SEVERE WEATHER EXPECTED TONIGHT...

.DISCUSSION...981MB SURFACE LOW LIFTING INTO NORTHERN MN. AS
FEARED...WARM FRONT HAS UTTERLY FAILED TO LIFT NORTHWARD THRU
EASTERN UPPER MI...WITH SE WINDS AND COOL TEMPS IN THE ST MARYS
VALLEY. TORNADO WATCHES ARE ALREADY UP UPSTREAM...AS DEEP CONVECTION
HAS FIRED ALONG A COLD FRONT MARCHING ACROSS IOWA AND INTO WESTERN
WI. CONVECTIVE TRENDS TONIGHT ARE THE CLEAR MAIN PROBLEM OF THE DAY.
STILL-STRONG SYNOPTIC WINDS ARE A SECONDARY CONCERN.

TONIGHT...IN SHORT...WEATHER STILL LOOKS NASTY TONIGHT.

LOW CLOUD DECK IN WI IS OCCURRING IN THE AREA WITH THE HIGHEST
LOW-LEVEL MOISTURE CONTENT...AND WHERE DEEP CONVECTION IS INHIBITED
BY A CAP (THOUGH SOME CELLS HAVE FIRED IN NE WI). THE BACK EDGE OF
THAT CLOUD DECK IS WHERE COLD ADVECTION AND ASCENT ALOFT IS
RUPTURING THE CAP...THUS THAT IS WHERE STORMS ARE FIRING.
EXTRAPOLATION AND MODEL PROGS AGREE THAT THIS CAP EROSION WILL ENTER
NORTHERN/WESTERN PARTS OF THE FORECAST AREA AS SOON AS 03Z IN
WESTERN CHIP/MACK...03Z TO 06Z THRU EASTERN UPPER AND ENTERING NW
LOWER MI...AND LATER IN NE LOWER. THIS IS IN CONCURRENCE WITH
EARLIER TIMING FORECASTS. CURRENT ACTIVITY IN NE WI DOES NOT APPEAR
TO BE SURFACE BASED...AND SHOULD NOT DEVELOP INTO ANYTHING MAJOR
GIVEN THE STRONG CAP IN PLACE HERE (IT IS NOT TAPPING AS MUCH
INSTABILITY AS ACTIVITY FURTHER WEST).

IF ANYTHING...INSTABILITY LOOKS TO BE GREATER THAN EARLIER PROGGED.
SURFACE TEMPS IN THE MID/UPPER 70S...AND DEW POINTS IN THE LOWER
60S...SUPPORT ML CAPES AROUND 1K J/KG. THAT IS A CONSIDERABLE AMOUNT
OF SURFACE BASED CAPE...ESPECIALLY FOR THE MIDDLE OF THE NIGHT. WHEN
COMBINED WITH 50-60KT 850MB WINDS...AND 70KT 500MB WINDS (AND A NEAR
100KT JET UPSTREAM)...THE SET-UP IS EXCEPTIONALLY POTENT.

THERE IS SIGNIFICANT MID-LEVEL DRY AIR UPSTREAM OF THE DEVELOPING
UPSTREAM STORMS. THIS SHOULD ALLOW SIGNIFICANT COLD POOL
PRODUCTION...AND PRODUCE A TRANSITION TO LINEAR MULTICELL
CONVECTION WITH TIME. STORMS MAY MOVE THRU AS A SINGLE BIG LINE...
OR IN MULTIPLE SMALLER LINE SEGMENTS. STRAIGHT LINE WINDS ARE THE
MAIN CONCERN...AND COULD BE EXTENSIVE. ISOLATED TORNADOES ARE
POSSIBLE...EITHER NON-SUPERCELLULAR WITH BOWING LINE SEGMENTS. THE
POTENTIAL FOR EMBEDDED SUPERCELLS CANNOT BE IGNORED AS WELL...NOW
THAT IT LOOKS MORE UNSTABLE THAN EARLIER PROGGED. THAT POTENTIAL
WOULD BE HIGHER WITH MULTIPLE SMALLER LINE SEGMENTS...RATHER THAN
ONE BIG LINE.

SMALL ADJUSTMENTS TO TIMING OF PRECIP WILL BE MADE IN THE GRIDS...
BUT BY AND LARGE THE THUNDER FORECAST WILL REMAIN UNCHANGED.

WILL CARRY WIND ADVISORY THRU 8 PM. MULTIPLE REPORTS OF TREE DAMAGE
RECEIVED FROM MANISTEE COUNTY...THOUGH GENERALLY OB SITES ARE
STAYING SHORT OF CRITERIA. THAT SAID...A 42MPH GUST AT GLR IS
RESPECTABLE. WINDS SHOULD SUBSIDE OVER LAND AFTER PEAK HEATING. FEEL
REASONABLY COMFORTABLE IN KEEPING GALES ONLY WHERE COASTAL
CONVERGENCE IS MOST FAVORABLE...WHICH IS SOUTH OF SLEEPING BEAR.

ZOLTOWSKI

FRIDAY...MODEL DATA IS IN GOOD AGREEMENT WITH THE STORM SYS MOVING
OVR THE UPPER MIDWEST AND CENTRAL PLAINS. THE FRONT IS FCST TO BE
ARND LAKE MICHIGAN/NW LWR MI BY 12Z FRIDAY. THE FRONT IS THEN FCST
TO MOVE EAST OF LAKE HURON BTW 18Z AND 21Z FRI. THE AIRMASS IN
ADVANCE OF THE FRONT WILL REMAIN MST AND UNSTABLE WITH 850 DEW PTS
AROUND 14C...LIS AROUND ZERO...K INDEX OF 36C...CAPES NEAR 1400
J/KG AND 850 MB WINDS NEAR 35 MPH. WILL CONT WITH SHOWERS AND
THUNDERSTORMS ALL ZONES IN THE MORNING IN ADVANCE OF THE FRONT. COULD
SEE SOME LOCALLY HEAVY RAINFALL WITH 850 DEW PTS OF 14C AND A K
INDEX NEAR 37C. HOWEVER STORMS SHOULD BE MOVING RATHER FAST WITH 850
MB WINDS TO 35 KNOTS...SO WILL LEAVE OUT MENTION OF HEAVY RAIN AT
THIS POINT. WILL DROP MENTION OF THUNDERSTORMS OVER NORTHWEST LOWER
IN THE AFTERNOON....BUT WILL KEEP THE MENTION OF AFTN THUNDERSTORMS
ALONG THE LAKE HURON SHORELINE UNTIL FRONT PASSES EAST OF THE LAKE.
WILL KEEP A SMALL CHANCE OF AFTN SHOWERS IN THE FORECAST FOR
NORTHWEST LOWER AND EAST UPPER...AS LINGERING UPPER LEVEL CYCLONIC
FLOW AND MSTR CONTS TO INFLUENCE THE UPPER LAKES. HIGH TEMPERATURES
AND HOURLY TEMP TRENDS WILL BE TOUGH TO NAIL DOWN FOR FRIDAY. 850 MB
TEMPS AHEAD OF THE FRONT WILL BE NEAR 16C FALLING TO 4C/5C OVER THE
WESTERN LAKES BEHIND THE FRONT IN THE AFTERNOON. WILL KEEP NORTHEAST
LOWER WARM THROUGH THE DAY...HOWEVER WILL MENTION TEMPS FALLING OR
NEAR STEADY OVER NORTHWEST LOWER AND EAST UPPER MICHIGAN.

FRIDAY NIGHT...NEARLY ZONAL FLOW ALOFT WILL COMBINE WITH AN AREA OF
HIGH PRESSURE BUILDING BACK INTO THE REGION FROM THE SOUTH AND WEST.
COOLER AND DRIER AIR WILL ALSO FILTER INTO THE REGION FRIDAY NIGHT.
SOUNDING DATA AND MSTR PROGS SHOW 850/500 MB RH DROPPING TO AROUND
30 PCT. OVERALL WILL MENTION SKIES BECOMING PARTLY CLOUDY WITH DRY
CONDITIONS.

SATURDAY...SURFACE HIGH PRESSURE STRENGTHENS OVER THE GREAT LAKES...
WHILE BECOMING CENTERED OVER THE STATE BY THE AFTERNOON. AT UPPER
LEVELS...A 850 MB RIDGES BUILDS IN OVR THE REGION WITH NEARLY ZONAL
FLOW AT 500/700 MB. MODEL SOUNDING DATA AND MSTR PROGS AGAIN SHOWING
DRY CONDS TO LINGER OVER THE REGION...AS 850/500 MB RH DRYS A LITTLE
MORE TO 25 PCT. MODEL SOUNDINGS SHOW MIXING THROUGH 850 MB...WHILE
850 MB TEMPS ARE PROGGED TO BE AROUND 8C/9C. OVERALL WILL MENTION
AFTN HIGHS IN THE MID 70S WITH MOSTLY SUNNY SKIES. SATURDAY NIGHT
WILL LEAVE DRY AS SURFACE HIGH PRES REMAINS CENTERED OVER THE GREAT
LAKES. ADDITIONAL SUBSIDENCE WILL BE GENERATED BY AN UPPER LVL RIDGE
BUILDING OVER THE STATE THROUGH THE EVENING.

SUNDAY THROUGH THURSDAY...
HIGH PRESSURE WILL DOMINATE THE FORECAST SUNDAY THROUGH WEDNESDAY...
AS THE AREA OF HIGH PRESSURE THAT WAS CENTERED OVER THE STATE
SUNDAY...ROTATES SLOWLY TOWARD THE EAST COAST AND BECOMES ELONGATED
ALONG THE MID ATLANTIC SEABOARD FOR THE BEGINNING OF THE UP COMING
WORK WEEK. CORRESPONDING UPPER LEVEL PATTERNS SUGGEST...RIDGING TO
BEGIN BUILDING INTO THE GREAT LAKES SUNDAY AND STRENGTHENING THROUGH
THE UP COMING WORKWEEK. THE UPPER RIDGING PATTERN REACHES FULL
STRENGTH OVER THE REGION TUESDAY AND WEDNESDAY IN ADVANCE OF A
DEVELOPING STORM SYSTEM OVR THE CENTRAL PLAINS/UPPER MIDWEST. 850
MB TEMPS CONTINUALLY WARM OVER THE GREAT LAKES THROUGH THE PERIOD IN
RESPONSE TO THE STRENGTHENING UPPER LEVEL RIDGING PATTERN. 850 MB
TEMPS WARM FROM 11C MONDAY TO NEAR 16C TUESDAY NIGHT AND WEDNESDAY.
THEREFORE WILL SLOWLY WARM TEMPS FROM THE MID 70S SUNDAY TO THE LOW
AND MID 80S WED. WILL KEEP THURSDAY DRY FOR NOW...EVEN WITH THE
DEVELOPING CENTRAL PLAINS/UPPER MIDWEST STORM SYSTEM PUSHING TWD
THE WRN LAKES. THE STRENGTH OF THE SURFACE AND UPPER LEVEL RIDGING
PATTERNS SHOULD KEEP THAT SYSTEM AT BAY UNTIL FRIDAY/SATURDAY.
