AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
727 AM EDT SUN APR 22 2012

.SYNOPSIS...
ISSUED AT 400 AM EDT SUN APR 22 2012

STRONG LOW PRESSURE MOVING UP THE EAST COAST WILL RESULT IN SEVERAL
DAYS OF COOL AND DRY WEATHER OVER MICHIGAN ALONG WITH BRISK
NORTHERLY WINDS. THE NEXT CHANCE FOR SHOWERS WILL MOST LIKELY COME
WEDNESDAY.

&&

.SHORT TERM...(TODAY THROUGH MONDAY AFTERNOON)
ISSUED AT 400 AM EDT SUN APR 22 2012

MAIN ISSUE IS FROST/FREEZE POTENTIAL AGAIN TONIGHT. SKIES SHOULD BE
CLEAR BUT WINDS WILL LIKELY STAY UP AROUND 5 TO 10 KTS TONIGHT AS
THE PRESSURE GRADIENT STRENGTHENS BETWEEN THE MID ATLANTIC LOW AND
RIDGE TO OUR WEST.

A FREEZE WATCH/WARNING MAY BE REQUIRED FOR ALL OUR PORTIONS OF OUR
FCST AREA TONIGHT GIVEN THE NORTHERLY FLOW CAA. 00Z MET/MAV GUIDANCE
NUMBERS FAVOR OUR NORTHERN FCST AREA MAINLY NORTH OF I-96 FOR BEST
FREEZE POTENTIAL TONIGHT. WILL LET THE DAY SHIFT HOIST THE
APPROPRIATE HEADLINE TO COVER THIS AFTER OUR CURRENT FREEZE HEADLINE
FOR OUR NORTHERN FCST AREA EXPIRES AT 13Z AND AFTER REVIEWING ALL
THE 12Z GUIDANCE/TRENDS.

IT WILL BE SEASONABLY COOL TODAY WITH MAX TEMPS ONLY REACHING THE
LOW TO MID 50S. NNE SFC WINDS WILL RAMP UP TO AROUND 15 TO 20 MPH
THIS AFTN.  COOL TEMPS ONLY IN THE 50S ANTICIPATED AGAIN FOR MONDAY
AFTN WITH PARTLY TO MOSTLY SUNNY SKIES BUT A BRISK NW WIND THAT
SHOULD RAMP UP TO AT LEAST 20 TO 25 MPH MON AFTN WITH HIGHER GUSTS.

.LONG TERM...(MONDAY NIGHT THROUGH SATURDAY)
ISSUED AT 400 AM EDT SUN APR 22 2012

THE 00Z EURO REMAINS SOUTH OF THE GFS WITH THE SFC LOW MOVING
THROUGH DURING THE MID WEEK PERIOD. TRENDED TIMING AND COVERAGE OF
POPS CLOSER TO THE EURO WHICH HAS SHOWN GOOD RUN TO RUN CONSISTENCY
HERE.

ANOTHER CANADIAN SFC HIGH COMES DOWN IN THE WAKE OF THIS LOW FOR THE
END OF THE WEEK WITH FAIR WEATHER BUT FROSTY NIGHTS. IT APPEARS THE
HIGH WILL HOLD IN PLACE INTO THE WEEKEND WITH RETURN FLOW MOISTURE
NOT ARRIVING UNTIL AFTER SATURDAY.

&&

.AVIATION...(FOR THE 12Z TAFS THROUGH 12Z MONDAY MORNING)
ISSUED AT 727 AM EDT SUN APR 22 2012

VFR THROUGH THE PERIOD. WINDS WILL INCREASE THIS AFTERNOON WITH
GUSTS TO NEAR 20 KNOTS AT TIMES BEFORE DIMINISHING IN THE EVENING.

&&

.MARINE...
ISSUED AT 400 AM EDT SUN APR 22 2012

NE WINDS WILL RAMP UP TO AROUND 20 KTS THIS AFTN. THE OFFSHORE
COMPONENT TO THE WIND SHOULD KEEP WAVE HEIGHTS BELOW SCA CRITERIA
OVER OUR NEARSHORE WATERS. WIND SPEEDS MAY FLIRT WITH SCA CRITERIA
THIS AFTN BUT IT WILL BE QUITE MARGINAL. AM MORE CONFIDENT THAT AN
SCA WILL BE NEEDED FOR MONDAY AS WINDS STRENGTHEN AND BACK TO THE
NW.

&&

.HYDROLOGY...
ISSUED AT 400 AM EDT SUN APR 22 2012

NO HYDROLOGY CONCERNS. ALL RIVERS ARE BELOW BANKFULL AND DRY WEATHER
IS FORECAST THIS WEEKEND THROUGH EARLY NEXT WEEK.
