AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
1200 PM EST FRI MAR 11 2011

LATEST UPDATE...AVIATION...

.SYNOPSIS...(405 AM EST FRI MAR 11 2011)
WE WILL BE IN BETWEEN WEATHER SYSTEMS TODAY WHICH WILL ALLOW FOR
INCREASING AMOUNT OF SUNSHINE THROUGH THE MORNING HOURS AND
CONTINUING THIS AFTERNOON.  A FAST MOVING LOW PRESSURE SYSTEM WILL
ARRIVE LATE TONIGHT AND BRING MOSTLY RAIN...ALTHOUGH SOME LIGHT
FREEZING RAIN WILL BE POSSIBLE ACROSS CENTRAL LOWER MICHIGAN.  THE
RAIN IS EXPECTED TO CHANGE TO SNOW ON SATURDAY AS THE LOW PASSES TO
OUR EAST.  HOWEVER...THE SNOW WILL REMAIN LIGHT...WITH ONLY A LIGHT
DUSTING EXPECTED NORTH OF INTERSTATE 96.  SUNDAY LOOKS TO BE DRY
WITH TEMPERATURES IN THE 30S.

&&

.SHORT TERM...(949 AM EST FRI MAR 11 2011)
(TODAY THROUGH SUNDAY)
I DID A QUICK UPDATE TO SLOW THE CLEARING OF THE LOW CLOUDS A TOUCH.
IT MAY TAKE UNTIL EARLY AFTERNOON FOR SKIES TO BECOME MOSTLY CLEAR
OVER THE CENTRAL AND EASTERN CWA. THE WEST EDGE OF THE LOW CLOUDS IS
JUST COMING INTO THE GRR AREA AS I WRITE THIS.

PREVIOUS DISCUSSION...THE CWA WILL REMAIN ON THE WESTERN EDGE OF A
STORM SYSTEM CENTERED NEAR BUF THIS MORNING.  HOWEVER...THE LOW WILL
CONTINUE TO DRIFT NE AWAY FROM THE AREA...WITH SURFACE RIDGING
PUSHING IN.  THE BACK EDGE OF THE CLOUD COVER WAS OVER LAKE MICHIGAN
AS OF 08Z AND IS EXPECTED TO PROGRESSIVE EASTWARD ACROSS THE CWA
THROUGH THE MORNING HOURS. THE AFTERNOON SHOULD FEATURE ABUNDANT
SUNSHINE...ALTHOUGH HIGH CLOUDINESS SHOULD RETURN TOWARD SUNSET.
WITH THE SUNSHINE...MAX TEMPS SHOULD REACH AROUND 40 IN MOST
LOCATIONS.

A FAST MOVING CLIPPER WILL IMPACT THE REGION LATE TONIGHT.  THE
TREND IS FOR THIS SYSTEM TO TRACK FURTHER NORTH...ACROSS THE
NORTHERN GREAT LAKES.  THIS WILL ALLOW WARMER AIR TO MOVE INTO THE
CWA AHEAD OF THE SYSTEM.  MIN TEMPS WILL PROBABLY OCCUR EARLY THIS
EVENING PRIOR TO THE ARRIVAL OF ANY PCPN...THEN TEMPS WILL RISE THE
REMAINDER OF THE NIGHT.  GIVEN THIS...THE PCPN TYPE SHOULD LARGELY
BE PLAIN RAIN.  HOWEVER...CONCERN THAT THE NORTHERN CWA MAY STRUGGLE
TO OVERCOME THE SHALLOW COLD AIR AND SOME LIGHT FREEZING RAIN MAY
OCCUR OVER CENTRAL LOWER LATE TONIGHT.

THE SYSTEM RACES ACROSS THE STATE SATURDAY MORNING WITH INCREASING
WINDS AND FALLING TEMPS EXPECTED THROUGH THE AFTERNOON.  ANY RAIN
SHOULD SWITCH OVER TO LIGHT SNOW.  DUE TO THE FAST MOVEMENT OF THIS
SYSTEM...THE PCPN AMOUNTS WILL BE LIGHT...GENERALLY A TENTH OF AN
INCH OR LESS.  AND ANY SNOW ACCUMULATION IS ONLY EXPECTED TO BE A
DUSTING NORTH OF I-96.

I REDUCED POPS FOR SATURDAY NIGHT AS THE SYSTEM FLIES QUICK PAST.
ONLY EXPECTING A FEW FLURRIES NOW FOR MOST OF THE CWA.  SUNDAY LOOKS
DRY AS HIGH PRESSURE NOSES INTO THE WESTERN GREAT LAKES.  HOWEVER
THE LOW LEVEL MOISTURE LINGERS...SO AT THIS POINT ONLY EXPECT
PARTIAL CLEARING.

&&

.LONG TERM...(405 AM EST FRI MAR 11 2011)
(SUNDAY NIGHT THROUGH THURSDAY)
THE MAIN MESSAGE FOR NEXT WEEK IS THAT A PATTERN SHIFT TOWARD MILDER
TEMPERATURES LOOKS TO BE IN STORE. 160 KT JET MOVING EAST ACROSS THE
PACIFIC EVENTUALLY INDUCES TROUGHING ALONG THE WEST COAST... WHICH
IN TURN LEADS TO RISING HEIGHTS OVER THE GREAT LAKES REGION.

ECWMF/GFS STILL NOT IN AGREEMENT ON THE TIMING OF THE FRONT
TUESDAY-WEDNESDAY IN FAST ZONAL FLOW... BUT EITHER WAY THIS LOOKS
LIKE A RATHER WEAK FRONT WITH ONLY LIGHT QPF EXPECTED. CURRENTLY WE
HAVE POPS FOR LIGHT RAIN SHOWERS ON BOTH TUESDAY NIGHT AND
WEDNESDAY TO COVER THE TIMING UNCERTAINTY... BUT THERE WILL PROBABLY
ONLY BE ABOUT A 6 TO 12 HOUR PERIOD OF RAIN SHOWERS.

THE MAIN SURGE OF WARM AIR IS PROGGED FOR WED NIGHT AND THURSDAY
WITH BOTH THE GFS AND ECMWF SHOWING H8 TEMPS RISING TO 8 TO 10C. THE
GFS IS SHOWING THE POSSIBILITY OF CONVECTION IMPACTING THE REGION AS
THE STRONG PACIFIC JET SPREADS INLAND... BUT THE EURO MODEL LOOKS
FAIRLY DRY. WILL MAINTAIN POPS FOR RAIN WED NIGHT AND THURS... BUT
HAVE HELD OFF ON A THUNDER THREAT UNTIL THE MODELS SHOW BETTER
AGREEMENT. WILL HAVE HIGHS IN THE MID 50S BOTH WED AND THU.

&&

.AVIATION...(1200 PM EST FRI MAR 11 2011)
VFR CONDITIONS ANTICIPATED THIS AFTERNOON AND EVENING. BRISK NW
WINDS GUSTING TO 20 KTS WILL SUBSIDE QUICKLY EARLY THIS EVENING.
CONDITIONS WILL GRADUALLY DETERIORATE FROM VFR TO MVFR DURING THE
EARLY TO MID MORNING HOURS SATURDAY AS A LOW CLOUD DECK MOVES IN.
IT WILL ALSO BECOME WINDY BEGINNING LATE SATURDAY MORNING WITH
SOUTHWEST WINDS SUSTAINED AT 15 TO 20 KTS WTIH GUSTS OF 25 TO NEAR
30 KTS. A FEW FLURRIES ARE ALSO POSSIBLE SATURDAY MAINLY NEAR TO
NORTH OF I-96.

&&

.MARINE...(405 AM EST FRI MAR 11 2011)
BRISK NW WINDS WILL CONTINUE MUCH OF THE DAY...BUT WILL DIMINISH
LATE.  SO WILL CONTINUE THE SCA UNTIL 5 PM.  THE CLIPPER SYSTEM ON
SATURDAY WILL BRING EVEN STRONGER WINDS.  THEREFORE HAVE HOISTED A
GALE WATCH AS THE COLD ADVECTION BEHIND THE SYSTEM BRINGS IN STRONG
WEST WINDS BY LATE MORNING.

&&

.HYDROLOGY...(405 AM EST FRI MAR 11 2011)
FLOOD ADVISORIES FOR MINOR RIVER FLOODING CONTINUE.  PCPN WITH THE
SYSTEM FOR LATE TONIGHT INTO SATURDAY EVENING IS EXPECTED TO BE
LIGHT.  ALSO...TEMPS WILL CONTINUE TO FALL BELOW FREEZING AT
NIGHT...RESULTING IN A SLOW DAYTIME SNOW MELT THROUGH THE WEEKEND.

&&

.GRR WATCHES/WARNINGS/ADVISORIES...
MI...NONE.
LM...SMALL CRAFT ADVISORY TODAY THROUGH 5 PM FOR THE ENTIRE NEAR
     SHORE.
     GALE WATCH SATURDAY FOR THE ENTIRE NEAR SHORE.
