AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
1150 PM EDT FRI SEP 30 2011

LATEST UPDATE...AVIATION...

.SYNOPSIS...(335 PM EDT FRI SEP 30 2011)
WINDS ON THE DECREASE THIS EVENING...WITH LINGERING LIGHT RAIN
SHOWERS POSSIBLE FOR SOME LOCATIONS THROUGH SATURDAY. FROST IS
POSSIBLE BOTH SATURDAY AND SUNDAY MORNINGS. HIGH PRESSURE WILL BRING
DRIER AND WARMER WEATHER TO THE REGION NEXT WEEK.

&&

.SHORT TERM...(335 PM EDT FRI SEP 30 2011)
(TONIGHT THROUGH SUNDAY NIGHT)

WINDY CONDITIONS AND SCATTERED LIGHT RAIN SHOWERS TO CONTINUE
THROUGH THIS EVENING BEFORE THINGS GRADUALLY IMPROVE TONIGHT AND
EARLY SATURDAY. SOME LINGERING MOISTURE LIKELY TO HANG ON THROUGH
MOST OF TONIGHT...AND IN THE FAR EASTERN ZONES ON SATURDAY AS THE
COOLER NORTHERLY FLOW REMAINS ESTABLISHED OVER THE GREAT LAKES
REGION. ANOTHER CONCERN FOR TONIGHT IS FROST...THOUGH LACK OF
CLEARING SKIES AND THE CONTINUED BREEZE SHOULD HELP TO KEEP MOST
LOCATIONS FROM HITTING THE FREEZING MARK OVERNIGHT.

SATURDAY WILL BE BREEZY AND COOL STILL...THOUGH WINDS WILL BE MUCH
LESS THAN WHAT OCCURRED TODAY. FROST MORE LIKELY FOR THE ENTIRE
REGION SATURDAY NIGHT INTO EARLY SUNDAY AS WINDS REALLY LIGHTEN UP
AND CLOUDS MOVE OFF TO THE EAST.

UPPER LEVEL RIDGE OF HIGH PRESSURE BEGINS TO SLOWLY MOVE EAST
SATURDAY NIGHT AND SUNDAY WITH MOSTLY SUNNY SKIES AND TEMPERATURES
REBOUNDING INTO THE UPPER 50S T6O LOWER 60S.

&&

.LONG TERM...(335 PM EDT FRI SEP 30 2011)
(MONDAY THROUGH NEXT WEEKEND)

CONFIDENCE REMAINS HIGH FOR A STRETCH OF ABOVE NORMAL TEMPERATURES
AND BELOW NORMAL PRECIPITATION FOR NEXT WEEK. UPPER AIR PATTERN WILL
FEATURE AN AMPLIFYING LONG WAVE TROUGH OVER THE WESTERN U.S. AND A
CORRESPONDING BUILDING LONG WAVE RIDGE OVER THE EAST. H85 TEMPS WILL
WARM TO 15C BY TUE SUPPORTING FCST HIGHS IN THE 70-75F RANGE TUE
THROUGH FRI. BOUTS OF MORNING FOG LIKELY TO BE THE ONLY POSSIBLE
WEATHER HAZARD OF THE EXTENDED PERIOD.

BY THE LATTER PART OF NEXT WEEK...THE GFS BECOMES MUCH MORE
PROGRESSIVE WITH WESTERN LONG WAVE TROUGH EJECTING AN UPPER
SHORTWAVE AND SFC FRONT EASTWARD INTO THE REGION LATE SATURDAY...
WHILE
ECMWF IS MUCH SLOWER AND WEAKER WITH EJECTING SHORTWAVE ENERGY
KEEPING THE REGION UNDER THE UPPER RIDGE.  GIVEN GFS PROCLIVITY TO
BE OVERLY PROGRESSIVE IN THE LONG RANGE FEEL THE ACTUAL ATMOSPHERIC
EVOLUTION WILL END UP CLOSER TO THE ECMWF SOLUTION THAN THE GFS AND
WITH THE ABOVE NORMAL TEMPS AND DRY PERIOD LASTING THROUGH NEXT
WEEKEND.

&&

.AVIATION...(1150 PM EDT FRI SEP 30 2011)
NORTHERLY FLOW WAS DRAWING DOWN SOME DRIER AIR FROM THE KCAD
REGION.  THIS SHOULD ALLOW FOR TAFS TO TRANSITION TOWARD VFR WEATHER
OVER THE NEXT FEW HOURS.  SKIES COULD END UP SCATTERING OUT
OVERNIGHT.

GUSTY WINDS COULD DEVELOP ON SATURDAY AS TEMPERATURES TRY TO WARM
UP. THIS WARMING WILL CAUSE MIXING THAT WILL CAUSE THE WINDS TO
INCREASE. THE FLOW WILL BE MAINLY FROM THE NORTH.  AM NOT EXPECTING
MUCH IN THE WAY OF CLOUD COVER.

&&

.MARINE...(335 PM EDT FRI SEP 30 2011)
GALE WARNING IN EFFECT THROUGH 2 AM SATURDAY AS WIND GUSTS UP TO 45
KNOTS WILL CONTINUE ALONG WITH WAVES UP TO 15 FEET. WINDS AND WAVES
WILL FALL OFF LATE TONIGHT AND INTO EARLY SATURDAY...THOUGH WINDS UP
TO 25 KNOTS AND WAVES UP TO 6 FEET OR SO CAN BE EXPECTED TO REMAIN
THROUGH SATURDAY EVENING.

&&

.HYDROLOGY...(335 PM EDT FRI SEP 30 2011)
SCATTERED LIGHT RAIN SHOWERS WILL OCCUR THROUGH MIDDAY SATURDAY.
ONLY LIGHT PRECIPITATION IS EXPECTED AND RAINFALL SHOULD NOT POSE
ANY HYDROLOGY THREATS.  OTHERWISE...LITTLE CHANCE FOR PRECIPITATION
EXPECTED THROUGH THE END OF NEXT WEEK.

&&

.GRR WATCHES/WARNINGS/ADVISORIES...
MI...NONE.
LM...GALE WARNING IN EFFECT THROUGH 2AM EDT SATURDAY.
