AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
409 AM EDT SAT OCT 13 2012

.SYNOPSIS...
ISSUED AT 409 AM EDT SAT OCT 13 2012

THE CENTER OF A STRONG FALL STORM WILL PUSH OUT OF THE CENTRAL
PLAINS THIS EVENING AND REACH LOWER MICHIGAN SUNDAY AFTERNOON.
THIS SYSTEM WILL BRING STEADY SOAKING RAINS TODAY THROUGH SUNDAY.
MANY AREAS WILL SEE AROUND TWO INCHES OF RAIN...WITH SOME AREAS
POSSIBLY SEEING OVER THREE INCHES. THUNDERSTORMS WILL ALSO BE
SCATTERED ABOUT...ALTHOUGH SEVERE POTENTIAL APPEARS TO BE ONLY
ISOLATED AT THIS TIME. ALONG WITH THE RAIN...WINDS WILL BECOME
BRISK ON SUNDAY WITH GUSTS TO AROUND 30 MPH AT TIMES. THE RAINS
ARE EXPECTED TO MOVE OUT OF THE AREA SUNDAY NIGHT.

MUCH OF NEXT WEEK LOOKS QUIETER. THERE WILL BE THE CHANCE OF LIGHT
RAIN WEDNESDAY INTO THURSDAY.  TEMPERATURES SHOULD REMAIN NEAR NORMAL.

&&

.SHORT TERM...(TODAY THROUGH MONDAY)
ISSUED AT 409 AM EDT SAT OCT 13 2012

IMPRESSIVE SYSTEM TAKING SHAPE FOR THE WEEKEND WITH SOME OF THE
HEAVIEST AND MOST WIDESPREAD RAINS OF THE YEAR EXPECTED TO OCCUR TODAY
THROUGH SUNDAY. LOW PRESSURE IS EXPECTED TO TRACK FROM NEAR KANSAS
CITY TONIGHT...TO CHICAGO ON SUNDAY...AND ACROSS CENTRAL LOWER BY
SUNDAY EVENING.

PRECIPITABLE WATER VALUES OF 1.50 TO 1.75 LINGERS OVER SW MI FROM
THIS AFTERNOON THROUGH SUNDAY AFTERNOON. IN CONCERT WITH THIS
MOIST ENVIRONMENT WILL BE STRONG JET DYNAMICS THAT WILL HELP
PRODUCE A VERY EFFICIENT HEAVY RAIN SYSTEM. THE FIRST AREA OF
RAIN WAS ALREADY CROSSING LAKE MICHIGAN EARLY THIS MORNING. THIS
WAS BEING PRODUCED WITHIN THE WARM ADVECTION PATTERN OF THE LARGE
SYSTEM. EXPECT THIS TO CONTINUE TO BLOSSOM THROUGH THE MORNING AS
THE RIGHT ENTRANCE REGION OF THE 100 KT JET MOVES OVER LOWER
MICHIGAN TOWARD MID DAY.

WE SHOULD SEE A SLIGHT LULL IN THE STEADY RAIN EARLY THIS EVENING
AS THE JET DYNAMICS REORGANIZES TO OUR WEST. BUT THEN STEADY
MODERATE/HEAVY RAIN SHOULD RETURN BY MIDNIGHT DRIVEN BY A LOW
LEVEL JET AND ANOTHER FOCUSED RIGHT ENTRANCE UPPER JET REGION.
EXPECT ANOTHER PERIOD OF PERSISTENT RAINS THAT SHOULD LAST INTO
SUNDAY AFTERNOON. THE RAINS SHOULD FINALLY Y DIMINISH LATE SUNDAY
INTO SUNDAY NIGHT. ALL TOLD...MANY AREAS SHOULD RECEIVE AROUND TWO
INCHES OF RAIN OVER THE NEXT 36 HOURS...WITH SOME LOCALES SEEING
OVER THREE INCHES.

HEAVY RAINS SEEM TO BE THE BIGGEST ISSUE WITH THIS SYSTEM...BUT WE
COULD ALSO SEE THE CHANCE FOR SEVERE STORMS AS WELL AS STRONG
SYNOPTIC WINDS. THE INSTABILITY LATE THIS AFTERNOON INTO TONIGHT
SHOULD LARGELY BE ELEVATED...MAKING HAIL THE MAIN THREAT. AREAS
ALONG I-94 COULD BECOME SURFACE BASED WHERE SOME STRONGER WIND
GUSTS MAY OCCUR. THE BETTER CHANCE OF SURFACE BASED STORMS WILL
COME SUNDAY SOUTH OF I-96 AS WE GET IN THE WARM SECTOR WITH BOTH
WIND AND HAIL POSSIBLE. WE WILL ALSO NEED TO MONITOR WHERE THE
WARM FRONT SETS UP FOR POSSIBLE BRIEF SPIN UPS. HOWEVER SINCE THE
BEST DYNAMICS SEEM TO OCCUR WHEN WE ARE THE MOST STABLE...SEVERE
POTENTIAL SHOULD REMAIN LOW THROUGH THE EVENT.

AS FAR AS THE SYNOPTIC WIND THREAT...THERE SHOULD BE AN INVERSION
OVERHEAD FOR MUCH OF TODAY AND TONIGHT...NOT ALLOWING FOR THE
STRONGER WINDS TO MIX DOWN. BETTER CHANCES FOR STRONG WINDS COME
SUNDAY INTO SUNDAY EVENING WHERE THE INVERSION IS ERODED AWAY
ACROSS THE SOUTHERN CWA. I HAVE GUSTS TO 30 MPH IN THE SOUTH AND
ALONG THE LAKE SHORE FOR NOW.

.LONG TERM...(MONDAY NIGHT THROUGH FRIDAY)
ISSUED AT 409 AM EDT SAT OCT 13 2012

SFC RIDGE EXPECTED TO BRING FAIR WEATHER THROUGH TUESDAY THEN
NORTHERN STREAM SHORTWAVE APPROACHES BY TUESDAY NIGHT. THIS WAVE
DAMPS OUT QUICKLY WITH ONLY A SCATTERED SHOWERS...BUT THE WAVE
BEHIND IT IS MORE ENERGETIC AS IT DIVES OVER THE EASTERN PACIFIC
RIDGE AND EVENTUALLY CUTS OFF ACROSS THE UPPER MIDWEST OR GREAT
LAKES.

LOOKS LIKE CHANCE OF RAIN WILL BE IN THE FORECAST WEDNESDAY THROUGH
FRIDAY AS THE UPPER LOW SPINS IN PLACE. ECMWF AND GFS BEGIN TO
DIVERGE IN HANDLING THE UPPER LOW BY THURSDAY...BUT THIS DOES NOT
HAVE APPRECIABLE IMPACT ON THE SENSIBLE WEATHER FOR LOWER MICHIGAN
UNTIL AFTER THE EXTENDED PERIOD.

&&

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z SATURDAY NIGHT)
ISSUED AT 1152 PM EDT FRI OCT 12 2012

I MADE NO SIGNIFICANT CHANGES IN OUR ONGOING FORECASTS. CLEAR
SKIES WILL GIVE WAY TO INCREASING CLOUDS AFTER 09Z. RAIN SHOULD
OVERSPREAD THE I-96 TAF SITES BETWEEN 12Z AND 15Z. DUE TO THE
POSITION OF THE WARM FRONT... IFR CIGS/VSBY ARE EXPECTED FOR THOSE
SITES BY AFTERNOON (NORTH OF THE WARM FRONT). THE I-94 TAF SITES
SHOULD BE JUST SOUTH OF THE WARM FRONT SO CIGS/VSBY SHOULD BE VFR
IN THE MORNING THEN BECOME MVFR IN THE AFTERNOON. THERE IS ENOUGH
INSATIABILITY FOR THUNDERSTORMS AT ALL TAF SITES. WITH THE FRONT
STALLED NEAR I-96... I HAD TO KEEP VCTS FOR A LONG PERIOD OF TIME
SATURDAY INTO SUNDAY.

&&

.MARINE...
ISSUED AT 409 AM EDT SAT OCT 13 2012

WILL CONTINUE THE SCA FOR TODAY AND EXTEND IT THROUGH SUNDAY NIGHT.
WE MAY APPROACH GALES ON SUNDAY BUT THIS SEEMS TOO BORDERLINE TO
JUMP INTO ANY GALE HEADLINE AT TIME POINT.

&&

.HYDROLOGY...
ISSUED AT 409 AM EDT SAT OCT 13 2012

WE WILL THE STARTING OUT WITH VERY LOW RIVER LEVELS WHICH WILL
CERTAINLY HELP WITH THIS EVENT. ALSO THE 2-3 INCHES OF RAIN IS
