AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
742 PM EDT TUE JUN 7 2011

LATEST UPDATE...AVIATION...

.SYNOPSIS...(343 PM EDT TUE JUN 7 2011)
A COLD FRONT WILL ARRIVE WEDNESDAY NIGHT WITH SHOWERS AND
THUNDERSTORMS...BRINGING AN END TO THE HOT WEATHER. SOME OF THE
STORMS COULD BE SEVERE WITH HAIL AND HIGH WINDS. MUCH COOLER WEATHER
WILL PREVAIL INTO THE WEEKEND WITH SOME RAIN FRIDAY NIGHT INTO
SATURDAY MORNING.

&&

.SHORT TERM...(343 PM EDT TUE JUN 7 2011)
(TONIGHT THROUGH THURSDAY NIGHT)
ONE MORE HOT DAY ON WEDNESDAY BEFORE THE UPPER RIDGE FLATTENS AND
COOLER...WETTER WEATHER MOVES IN. TEMPS AND DEW POINTS ARE CURRENTLY
CLOSE TO HEAT ADVISORY CRITERIA AND WILL BE CLOSE AGAIN ON
WEDNESDAY. LACK OF MOISTURE AND WEAK CAPPING INVERSION HAS
EFFECTIVELY PREVENTED ANY CONVECTION TODAY DESPITE AMPLE MID LEVEL
INSTABILITY. CONVECTIVE INHIBITION CONTINUES THROUGH WEDNESDAY SO
WILL KEEP WEDNESDAY DRY FOR ALL BUT THE EXTREME NORTHWEST FORECAST
AREA AND BRING POPS IN WEDNESDAY EVENING.

SEVERE WEATHER REMAINS POSSIBLE WEDNESDAY NIGHT AS COLD FRONT MOVES
INTO VERY JUICY AIRMASS. MAIN THREAT APPEARS TO BE HAIL AND HIGH
WINDS WITH ABOUT 30 KNOTS OF 0 TO 6 KM UNIDIRECTIONAL SHEAR. SOME
BOWING LINE SEGMENTS COULD PRODUCE DAMAGING WINDS.

MUCH COOLER AIR BEHIND THE FRONT FOR THURSDAY. CLEARING WILL BE SLOW
FROM NORTH TO SOUTH WITH SHOWERS HANGING ON ACROSS THE SOUTHERN
FORECAST AREA MOST OF THE DAY. THE FRONT SHOULD CLEAR THE AREA BY
THURSDAY NIGHT BUT THEN STALLS AND A SFC WAVE BEGINS TO MOVE TOWARDS
LOWER MICHIGAN BY THURSDAY NIGHT WITH SHOWERS RETURNING.

&&

.LONG TERM...(343 PM EDT TUE JUN 7 2011)
(FRIDAY THROUGH TUESDAY)
MODELS ARE TRENDING WETTER FOR THE LATTER PART OF THE WEEK.  LOW
PRESSURE IS EXPECTED TO SLIDE OUT OF THE PLAINS STATES AND INTO THE
WESTERN GREAT LAKES BY FRIDAY NIGHT.  INITIALLY WE WILL BATTLE THE
DRIER EASTERLY FLOW COMING AROUND HIGH PRESSURE NEAR JAMES BAY.  BUT
THIS SHOULD BE OVERCOME BY EARLY TO MID DAY ON FRIDAY FOR SHOWERS
AND STORMS TO SPREAD IN.  THE SURFACE LOW IS EXPECTED TO CUT ACROSS
THE STATE EARLY SATURDAY...SO THE PCPN SHOULD COME TO AN END FROM
WEST TO EAST.

MAINTAINED A DRY FORECAST FROM SATURDAY NIGHT THROUGH MONDAY WITH
HIGH PRESSURE EXPECTED IN THIS TIME FRAME.  IT APPEARS THE
OPERATIONAL GFS IS THE OUTLIER...BREAKING DOWN THE RIDGE TOO QUICKLY
AND BRINGING PCPN IN BY EARLY MONDAY.  THE TREND IN MOST OTHER
MODELS SHOW THE NEXT CHANCE OF RAIN SHOULD HOLD OFF UNTIL AT LEAST
MONDAY NIGHT AS A MOIST RETURN FLOW DEVELOPS.

TEMPS WILL MODERATE THROUGH THE PERIOD...FROM THE COOLISH UPPER 60S
AND LOWER 70S IN THE PCPN ON FRIDAY...WARMING TO 80-85 BY TUE WITH
THE RETURN FLOW.

&&

.AVIATION...(742 PM EDT TUE JUN 7 2011)
VFR CONDITIONS ARE EXPECTED TO PREVAIL TONIGHT AND WEDNESDAY.
REMOVED THE MENTION OF CB/S SINCE PROBABILITY IS EXTREMELY LOW.
GUSTY SW SFC WINDS WILL DIMINISH BY 9 PM AND PICK AFTER AGAIN AFTER
13Z.

&&

.MARINE...(343 PM EDT TUE JUN 7 2011)
SOUTHWEST WINDS WILL BE IN THE 15 TO 25 KNOT RANGE TONIGHT AND
WEDNESDAY AND WAVES SHOULD REMAIN BELOW 4 FEET. SOME AREAS OF FOG
WILL BE NORTH OF GRAND HAVEN THROUGH WEDNESDAY. STRONG STORMS ARE
POSSIBLE WEDNESDAY NIGHT WITH WIND GUSTS OVER 35 KNOTS.

&&

.HYDROLOGY...(343 PM EDT TUE JUN 7 2011)
COLD FRONT WILL BRING SOME POTENTIAL FOR HEAVY RAIN WEDNESDAY NIGHT
BUT THE STORMS SHOULD BE MOVING QUICK ENOUGH TO PREVENT MUCH
FLOODING. MORE RAIN IS POSSIBLE AS LOW PRESSURE MOVES THROUGH BY THE
END OF THE WEEK BUT SHOULD NOT BE HEAVY ENOUGH TO CAUSE ANY
SIGNIFICANT RISES ON THE RIVERS.

&&

.GRR WATCHES/WARNINGS/ADVISORIES...
MI...NONE.
LM...NONE.
