AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
306 PM EDT SAT SEP 8 2012

.SYNOPSIS...
ISSUED AT 252 PM EDT SAT SEP 8 2012

EXPECT SHOWERS AND ISOLATED THUNDERSTORMS NEAR LAKE MICHIGAN
TONIGHT. THAT ACTIVITY WILL DIMINISH BY MID MORNING SUNDAY.
OTHERWISE EXPECT COOLER WEATHER TO PREVAIL INTO THE BEGINNING OF
THE WEEK. A WARMING TREND WILL BEGIN BY TUESDAY THAT WILL LAST
INTO THE END OF THE WEEK.

&&

.SHORT TERM...(THIS EVENING THROUGH MONDAY NIGHT)
ISSUED AT 252 PM EDT SAT SEP 8 2012

THE PRIMARY FORECAST CONCERN IS THE AREA OF SHOWERS MOVING
SOUTHEAST FROM WESTERN UPPER MICHIGAN AND HOW IT WILL IMPACT
SOUTHWEST LOWER MICHIGAN OVERNIGHT AS IT MOVES THROUGH.
OTHERWISE...I EXPECT TEMPERATURES TO FALL INTO THE 30S NEAR ROUTE
10 EAST OF THE LAKE SHORE SUNDAY NIGHT. AN EARLY TASTE OF FALL FOR
SURE.

A STRONG SHORTWAVE... WELL DEFINED ON THE WATER VAPOR LOOPS...
WILL CONTINUE TO DROP SOUTHEAST CROSSING SOUTHWEST LOWER MICHIGAN
DURING THE EARLY EVENING HOURS. THERE IS A 130 KNOT JET EXIT
REGION THAT CROSSES SOUTHERN LAKE MICHIGAN JUST BEFORE MIDNIGHT
ASSOCIATED WITH FEATURE. THIS JET CORE IS ROTATING AROUND THE BASE
OF THE CLOSED 300 MB LOW THAT IS ALSO ASSOCIATED WITH THIS
FEATURE. BOTH THE NAM12 AND HRRR RUC SUGGEST A MESO-LOW FEATURE
WILL DEVELOP ON THE EAST SIDE (MICHIGAN SIDE)OF THE LAKE AN TRACK
SOUTH THROUGH THE NIGHT ENHANCING THE CONVERGENCE OVER THE LAKE.
GIVEN THE 850 MB TO LAKE TEMP DIFFERENCE IS NEAR 15C. BUFKIT SHOWS
THE EQUILIBRIUM LEVEL OVERNIGHT WILL APPROACH 30000 FT AGL WITH
NEARLY 2000 J/KG OF LAKE EDUCED CAPE. I AM THINKING THIS IS
ENOUGH FOR SCT TO ISOLATED THUNDERSTORMS. LOCALLY HEAVY SHOWERS
SHOULD BE EXPECTED.  THAT THINKING IS CONFIRMED BY THE SPC SREF.
NEARLY ALL OF THIS WILL MOSTLY BE OVER LAKE MICHIGAN AND WEST OF
US-131 WHERE THE LAKE EDUCED INSTABILITY WILL BE A FACTOR. INLAND
OF THAT EXPECT PARTLY CLOUDY SKIES WITH POSSIBLY A PASSING SHOWER
AS THE UPPER WAVE MOVE THROUGH.

ONCE THIS FEATURE EXITS THE AREA MID TO LATE MORNING SUNDAY THE
UPPER RIDGE BUILDS IN THROUGH TUESDAY. THERE WILL BE ENOUGH
INSTABILITY YET FOR ISOLATED SHOWERS SOUTH OF ROUTE 10 AND EAST OF
US-131 SUNDAY AFTERNOON SINCE THE UPPER JET WILL NOT BE EAST OF
THERE YET.

SUNDAY NIGHT WITH SURFACE HIGH PRESSURE OVER THE AREA WINDS WILL
BE LIGHT AND SKIES CLEAR. I EXPECT LOWS IN THE MID 30S OVER OUR NE
CWA AND LOWER TO MID 40S ELSEWHERE. A SLOW WARMING TREND FOLLOWS
THEN WITH MOSTLY CLEAR SKIES THROUGH TUESDAY NIGHT.

.LONG TERM...(TUESDAY THROUGH SATURDAY)
ISSUED AT 305 PM EDT SAT SEP 8 2012

WE/LL START TO WARM UP AGAIN TUESDAY AS THE HIGH MOVES TOWARD NEW
ENGLAND. THE NEXT COLD FRONT WILL LIKELY MOVE ACROSS THE CWA
THURSDAY NIGHT OR FRIDAY. INSTABILITY DOESN/T LOOK VERY IMPRESSIVE
WITH THIS NOR DO THE MOISTURE TRANSPORT VECTORS. AS A RESULT I
CAN/T SEE MUCH MORE THAN SLIGHT CHC POPS AT THIS POINT. THERE IS A
COMPACT SHORT WAVE ASSOCIATED WITH THIS AND THAT MAY BOOST PCPN
CHANCES INTO SATURDAY...BUT GIVEN THE SFC RIDGING MOVING IN AT
THAT POINT...PCPN AMOUNTS AND CHANCES LOOK MEAGER.

TEMPS WILL CLIMB TO AROUND 80 PRIOR TO FROPA AND THAN BACK INTO THE
70S BY THE WEEKEND.
&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z SUNDAY AFTERNOON)
ISSUED AT 146 PM EDT SAT SEP 8 2012

THERE IS CERTAINLY A DIURNAL LOOK TO THE CU FIELD AND WE/LL SEE
ISOLD SHRA DIMINISH TOWARD SUSET AND SKIES WILL BECOME CLR-SCT.
HOWEVER STRATOCU WILL INCREASE LATE TONIGHT AS THE NEXT COLD FRONT
DROPS SOUTH. WINDS WILL VEER TO THE NNW 12Z-15Z AND CIGS SHOULD
DEVELOP AROUND 4K FT.

&&

.MARINE...
ISSUED AT 252 PM EDT SAT SEP 8 2012

I WILL CONTINUE THE SMALL CRAFT ADVISORIES AS IS INTO SUNDAY. IT
SHOULD BE NOTED THAT THERE CURRENTLY ARE GUSTY WINDS BEHIND THE
TROUGH AT THE SURFACE OVER NE MINNESOTA. THE HRRR RUC SHOWS AN
AREA OF 40 TO 50 KNOT WINDS OVER THE CENTRAL PART OF LAKE MICHIGAN
JUST BEHIND THE THROUGH OVERNIGHT. SO IN THE NEAR SHORE WATERS
EXPECT WINDS TO INCREASE SIGNIFICANTLY LATER TONIGHT FOR A FEW
HOURS BEHIND THE THROUGH. ALL OF THIS WILL END FROM NORTH TO SOUTH
DURING THE DAY SUNDAY AS THE SYSTEM MOVES OUT.

&&

.HYDROLOGY...
ISSUED AT 252 PM EDT SAT SEP 8 2012

RIVERS WILL CONTINUE TO FALL SLOWLY THROUGH THIS COMING WEEK AS
IT IS EXPECTED TO BE DRY MOST OF THIS COMING WEEK. ANY RAINFALL
WE GET TONIGHT WILL ONLY BE NEAR THE LAKE SHORE AND THAT WILL NOT
IMPACT MOST OF RIVERS.

&&

.GRR WATCHES/WARNINGS/ADVISORIES...
MI...NONE.
