AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
139 PM EDT TUE AUG 9 2011
LATEST UPDATE...AVIATION...
.SYNOPSIS...(428 AM EDT TUE AUG 9 2011)
A COLD FRONT WILL MOVE THROUGH THE AREA DURING THE DAY TODAY. A FEW
SPOTTY SHOWERS AND STORMS CAN BE EXPECTED. SEVERE WEATHER IS NOT
EXPECTED. MUCH COOLER AIR WILL THEN FILTER IN BEHIND THIS FRONT FOR
THE MID AND LATTER PART OF THIS WORK WEEK. HIGHS ARE ONLY EXPECTED
TO WARM INTO THE 70S ON WEDNESDAY AND THURSDAY. TEMPERATURES WILL
MODERATE SOME BY THE WEEKEND...BUT WILL COOL OFF AGAIN AS ANOTHER
FRONT AND MORE RAIN MOVES IN ACROSS THE AREA.
&&
.SHORT TERM...(1115 AM EDT TUE AUG 9 2011)
(THIS AFTERNOON THROUGH THURSDAY)
I HAVE UPDATED THE ZONES TO INCREASE THE POP TO 75 PCT NEAR ROUTE 10
AND STRETCH THAT WITH A GRADIENT SOUTHEASTWARD ACROSS THE CWA SINCE
WE ALREADY HAVE A CONVECTIVE LINE OVER MASON AND OCEAN COUNTIES
BUILDING QUICKLY SOUTHWARD ALONG THE 850 MB THERMAL RIDGE (14Z RUC).
THE SPC MESO PAGE SHOWS MOST UNSTABLE CAPE VALUES NEAR 2000 J/KG
OVER CENTRAL LAKE MICHIGAN AND THERE IS A POCKET OF HIGHER DEW
POINTS WITH THE HIGHER CAPE SO I EXPECT THE LINE WILL CONTINUE TO
BUILD AS IT HEADS EASTWARD. OUR TIMING TOOL SUGGESTS THE LINE SHOULD
BE EAST OF CLARE COUNTY BY 18Z AND EAST OF JACKSON COUNTY BY 20Z. I
ADJUSTED OUR POP GRID IN 3 HOURS INTERVALS TO TIME THE LINE ACROSS
THE CWA.
AS FOR THE THREAT OF SEVERE STORMS.... THERE IS A FAIR AMOUNT OF MID
LEVEL DRY AIR ON THE OTHER HAND WE DO HAVE CAPES OF 2000 J/KG TO
WORK WITH AND POCKET OF HIGHER DEW POINTS JUST AHEAD OF THE
FRONT... NEAR 70 DEGREES. THE UP SIDE TO THIS IS THE EFFECTIVE BULK
SHEAR IS BARELY 30 KNOTS OVER THE LINE NOW. I WOULD EXPECT THIS NOT
TO INCREASE WITH TIME SO WE SHOULD GET SOME DECENT STORMS BUT THEY
SHOULD STAY BELOW SEVERE LIMITS FOR THE MOST PART.
THE COLD ADVECTION AND STRONG CYCLONIC FLOW BEHIND THE COLD FRONT
MAY RESULT IN SOME LIGHT RAIN SHOWERS THIS EVENING SO I LET THAT
STAY IN THE GRIDS FOR THE OVERNIGHT HOURS. SKIES SHOULD REALLY
CLEAR BY MID TO LATE MORNING WEDNESDAY AS THE FLOW BECOMES
ANTICYCLONIC. THAT WILL MAKE FOR A RATHER CHILLY NIGHT WEDNESDAY
NIGHT WITH MOSTLY CLEAR SKIES AND LIGHT WINDS.
&&
.LONG TERM...(428 AM EDT TUE AUG 9 2011)
(THURSDAY NIGHT THROUGH MONDAY)
IT IS LOOKING MORE AND MORE LIKE A WET/UNSETTLED WEEKEND CAN BE
EXPECTED... AT LEAST FOR THE FIRST HALF OF THE WEEKEND.
MODELS REMAIN FAIRLY SIMILAR IN SHOWING A SFC COLD FRONT AND DIGGING
MID LEVEL SHORTWAVE TROUGH IMPACTING THE REGION FRIDAY NIGHT AND
SATURDAY. NUDGED UP POPS SLIGHTLY FOR THIS TIME FRAME... AND WE MAY
NEED TO GO WITH LIKELY/CATEGORICAL POPS EVENTUALLY IF MODELS REMAIN
CONSISTENT.
SOLUTIONS THEN DIFFER A BIT FOR THE LATTER HALF OF THE WEEKEND...
WITH THE EURO SUGGESTING FURTHER AMPLIFICATION/DEEPENING OF THE MID
LEVEL TROUGH AND PERHAPS EVEN A CLOSED H5 CIRCULATION DEVELOPING BY
12Z SUNDAY NEARBY. MEANWHILE THE GFS IS SHOWING A MORE PROGRESSIVE
NATURE TO THE H5 TROUGH.
POPS WERE ALREADY ADDED TO SATURDAY NIGHT AND MADE NO CHANGES THERE.
KEPT THE SUNDAY FCST DRY FOR NOW... BUT MAY NEED TO ADD SHOWERS AND
MORE CLOUDS TO LATER FCSTS IF THE EURO SOLUTION BECOMES MORE
BELIEVABLE.
&&
.AVIATION...(139 PM EDT TUE AUG 9 2011)
A NARROW BAND OF SHOWERS AND STORMS EXTENDED FROM HTL TO Y70 TO AZO
AS OF 1730Z. THIS BAND WILL PROGRESS EAST OF THE TAF SITES BY 20Z.
THUNDER...BRIEF HEAVY RAIN AND GUSTY WINDS COULD ACCOMPANY ANY
STORMS. THESE STORMS ARE ALONG A COLD FRONT THAT WAS PUSHING
THROUGH. ONCE IT PASSES SKIES WILL CLEAR FOR THE REMAINDER OF THE
AFTERNOON AS A DRY SLOT COMES THROUGH. ANOTHER AREA OF CLOUDS
FOLLOWS THE DRY SLOT. THESE MAY LOWER INTO THE MVFR RANGE FOR A
PERIOD OVERNIGHT. THESE CLOUDS SHOULD CLEAR OUT OF THE AREA BY MID
WED MORNING.
WEST WINDS WILL GUST 20-25 KNOTS THIS AFTERNOON BEHIND THE FRONT.
THEN AFTER A BRIEF LOWERING OF THE SPEEDS OVERNIGHT...NORTHWEST
WINDS WILL INCREASE AGAIN TO 15-20 KNOTS WEDNESDAY MORNING.
&&
.MARINE...(428 AM EDT TUE AUG 9 2011)
BIGGEST CONCERNS IN THIS FCST PACKAGE FOR MARINE INTERESTS ARE THE
WINDS AND WAVES FROM THIS AFTERNOON THROUGH WED NIGHT...AND THE
POTENTIAL FOR WATERSPOUTS FOR TONIGHT AND WED MORNING.
SW WINDS WILL INCREASE THIS AFTERNOON OUT AHEAD OF THE INCOMING COLD
FRONT. WINDS AND WAVES WILL BE MARGINAL FOR AN ADVISORY THIS
AFTERNOON...HOWEVER IT WILL BE CLOSE ENOUGH TO START THE ADVISORY
THIS AFTERNOON. THE BEST WINDS AND WAVES WILL COME OVERNIGHT TONIGHT
AND DURING THE DAY ON WEDNESDAY. THIS WILL BE WHEN WE SEE THE COLDER
AIR MOVE IN ALONG WITH THE TIGHT GRADIENT. THIS SETUP IS ALMOST
OPTIMAL FOR WAVE GENERATION WITH THE COLD STRONG WIND COMING IN OVER
THE LAKE WHERE WATER TEMPS ARE NEAR THEIR ANNUAL PEAK AND ARE WARMER
THAN THE AIR COMING IN. RIP CURRENTS AND UNDERTOW THREAT WILL BE
HIGH. WINDS WILL DIMINISH WED NIGHT.
WE HAVE ADDED A CHC OF WATERSPOUTS TO THE FCST FOR OVERNIGHT TONIGHT
AND WED MORNING. MODELS ARE INDICATING A LAKE CONVERGENCE BAND
EXPECTED TO BE OVER THE NEARSHORE WATERS. THIS COMBINED WITH THE
OVER WATER INSTABILITY...CLOUD DEPTH...AND THE WAVE COMING IN FROM
THE NORTHWEST ALL POINT TO A THREAT OF WATERSPOUTS. THE ONLY
LIMITING FACTOR MAY BE THE WINDS...BUT WE SHOULD STAY UNDER THE 35
KNOT CRITERIA THAT IS USUALLY THE THRESHOLD FOR BEING TOO STRONG FOR
WATERSPOUTS. THE THREAT SHOULD END WED AFTERNOON AS THE WAVE MOVES
BY AND RIDGING BUILDS IN.
&&
.HYDROLOGY...(428 AM EDT TUE AUG 9 2011)
SOME LOCALLY HEAVY RAIN HAS FALLEN ACROSS THE AREA THIS MORNING
WHERE SOME LOCALIZED TRAINING OF STORMS/SHOWERS TOOK PLACE. THE
THREAT IS DIMINISHING AS THE WAVE MOVES EAST OF THE AREA. A FEW
SHOWERS/STORMS WILL BE POSSIBLE ALONG THE FRONT...HOWEVER PCPN IS
NOT EXPECTED TO BE WIDESPREAD. ONCE THE PCPN MOVES OUT
TODAY/TONIGHT...WE SHOULD REMAIN DRY FOR AT LEAST A COUPLE OF DAYS.
RAINFALL IS EXPECTED ONCE AGAIN THIS WEEKEND. MOST AREAS WILL SEE A
HALF AN INCH OR SO...BUT NO FLOODING IS EXPECTED.

A National Weather Service Storm Survey Team confirmed an EF-0 tornado briefly touched down on Tuesday, August 9th, 2011 in Lafayette Township in Gratiot County. This tornado was on the ground for about 250 yards in Lafeyette Township causing significant damage to a 99 year old family farm. This same storm produced a weak EF-0 tornado that touched down briefly for about 200 yards in a corn field in Lakefield Township in Saginaw County. Some very minor crop damage was found along the path between the two tornado touchdowns. Maximum wind gusts were estimated to be around 80mph in Lafayette Township.
