AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
1212 PM EST FRI MAR 9 2012

.SHORT TERM...(TODAY THROUGH SATURDAY)
ISSUED AT 356 AM EST FRI MAR 9 2012

LAKE DELTA T/S WILL BE HOVERING IN THE UPPER TEENS THIS MORNING
AS THE SHORT WAVE PIVOTS THROUGH. INVERSION LEVELS ARE NEAR 7K FT
THROUGH MUCH OF THE MORNING...SO WE CONTINUE TO EXPECT A BRIEF
PERIOD OF LAKE EFFECT SNOW SHOWERS BEHIND THE SHORT WAVE. MUCH
DRIER AIR ARRIVES BETWEEN 15Z AND 18Z WHICH SHOULD BRING A QUICK
END OF ANY PCPN. BREAKS IN THE CLOUDS SHOULD DEVELOP THROUGH THE
REMAINDER OF THE DAY. THE COLD ADVECTION BEHIND THE WAVE WILL KEEP
TEMPS IN THE 30 TO 35 DEGREE RANGE MUCH OF THE DAY. A BRISK NW
WIND WILL KEEP WIND CHILL READINGS IN THE TEENS. THESE WINDS WILL
FINALLY DROP OFF TONIGHT WHICH WILL ALLOW TEMPERATURES TO FALL
INTO THE TEENS UNDER PARTLY CLOUDY SKIES.

BIG CHANGES WILL MOVE INTO THE AREA FOR THE WEEKEND. HIGH PRESSURE
WILL SLIDE BY FRIDAY NIGHT...WITH RETURN FLOW KICKING IN BY
SATURDAY. WE WILL BE UNDER A VERY DRY AIR MASS WHICH WILL ALLOW
FOR A QUICK TEMPERATURE RECOVERY AFTER THE CHILLY NIGHT. BELIEVE
TEMP GUIDANCE IS UNDER DOING THE INITIAL WARM UP. SO HAVE GONE A
FEW DEGREES ABOVE GUIDANCE WITH HIGHS ON SATURDAY IN THE UPPER 40S
TO LOWER 50S.

.LONG TERM...(SATURDAY NIGHT THROUGH THURSDAY)
ISSUED AT 356 AM EST FRI MAR 9 2012

MODELS ARE IN GOOD AGREEMENT IN TRACKING THE UPPER LOW OVER THE
SOUTHWEST U.S. INTO THE GREAT LAKES REGION SUNDAY NIGHT INTO
MONDAY.  WILL KEEP THE HIGHER POPS GOING.  WE WILL NEED TO  MONITOR
THE RISK FOR THUNDER WITH THIS SYSTEM AS WEAKNESS IN THE STABILITY
WAS NOTED...ESPECIALLY AROUND 850 MB. THIS SYSTEM WILL BE MOVING
ALONG AND WILL BE OUT OF THE REGION BY TUESDAY.

A BETTER RISK FOR THUNDER EXISTS WEDNESDAY.   INSTABILITY IS SHOWN
AND A DECENT MID LEVEL TROUGH PASSES NORTHEASTWARD THROUGH THE AREA.
WILL HOLD ONTO THIS IN THE FORECAST.

GIVEN THE CONTINUED DEEP SOUTHWEST FLOW...TEMPERATURES WILL REMAIN
WELL ABOVE NORMAL.  THE WARMEST DAY IN THE EXTENDED PERIOD LOOKS TO
BE WEDNESDAY WHEN 925 MB TEMPS MAKE AN ATTEMPT TO TOP 15 DEG C.
THIS WOULD SUPPORT TEMPERATURES CLIMBING WELL INTO THE 60S WITH 70
DEGREES WITHIN REACH.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z SUNDAY)
ISSUED AT 1212 PM EST FRI MAR 9 2012
SNOW SHOWERS ARE WINDING DOWN AND VFR CONDITIONS EXPECTED THROUGH
SATURDAY AFTERNOON. NORTHWEST WINDS WILL GUSTS OVER 20 KNOTS THIS
AFTERNOON BEFORE DIMINISHING BY 00Z. THEN SOUTH WINDS WILL PICK UP
AGAIN ON SATURDAY AND MAY BE GUSTING TO NEAR 20 KNOTS AGAIN BY THE
AFTERNOON.

&&

.MARINE...
ISSUED AT 356 AM EST FRI MAR 9 2012

HAVE EXTENDED THE GALE WARNING FOR THE SABLE POINTS REGION UNTIL
NOON TODAY. THE HEALTHY COLD ADVECTION WILL KEEP NW FLOW STRONG
THROUGH THE MORNING. WINDS ARE EXPECTED TO SLOWLY DIMINISH INTO
THE AFTERNOON. ELSEWHERE...A SCA WILL BE CONTINUED INTO TONIGHT.

ANOTHER PERIOD OF STRONG WINDS IS EXPECTED ON SATURDAY. SSW WINDS
COULD POTENTIALLY REACH GALE FORCE AGAIN.

&&

.HYDROLOGY...
ISSUED AT 356 AM EST THU MAR 8 2012
