AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
318 PM EDT WED OCT 3 2012

.SYNOPSIS...
ISSUED AT 241 PM EDT WED OCT 3 2012
A WEAKENING AREA OF LOW PRESSURE WILL LIFT NORTHWARD THROUGH LOWER
MICHIGAN TONIGHT. THIS SYSTEM WILL BRING WITH IT CLOUDS AND SOME
LIGHT RAIN. A COLD FRONT ARRIVES FROM THE WEST THURSDAY EVENING.
MORE SHOWERS AND EVEN A THUNDERSTORM MAY ACCOMPANY THE PASSAGE OF
THIS SYSTEM. BEHIND IT A MUCH COOLER AIRMASS WILL ARRIVE ON GUSTY
WEST WINDS FOR FRIDAY. OVERALL THE WEEKEND IS LOOKING UNSEASONABLY
COOL. THERE WILL BE SOME LAKE EFFECT RAIN SHOWERS NEAR THE LAKESHORE.

&&

.SHORT TERM...(THIS EVENING THROUGH FRIDAY NIGHT)
ISSUED AT 241 PM EDT WED OCT 3 2012

THE MAIN CHALLENGE DEALS WITH THE POTENTIAL FOR RAIN TONIGHT.
OVERALL THE TREND SUPPORTS EXPANDING THE LIKELIHOOD OF RAIN. THE
WEAK LOW PRESSURE SYSTEM IS MOVING IN FROM THE SOUTHWEST. RADAR
SHOWS AND EXPANDING AREA OF LIGHT RETURNS. OBS SHOW MOSTLY LIGHT
RAIN AND DRIZZLE. COOLER CLOUD TOPS WERE PIVOTING IN FROM
INDIANA...WHICH WILL HELP TO DEEPEN THE MOISTURE HERE IN SOUTHWEST
LOWER MI. OMEGA FIELDS ON BUFKIT DO SHOW DECENT LIFT IN THE
SATURATED LOWER LEVELS OF THE ATMOSPHERE. USUALLY THIS RESULTS IN
LOTS OF LIGHT RAIN AND DRIZZLE. WILL EXPAND THE COVERAGE OF RAIN
FOR TONIGHT.

THE BULK OF THE RAIN WILL BE OVER BY THURSDAY. COULD BE A FEW
LINGERING SHOWERS TO START THE DAY. BY NOON IT SHOULD BE DRY.
HOWEVER THE COLD FRONT SWINGS IN QUICKLY FROM THE WEST THU
EVENING. SOME INSTABILITY SHOWS UP AS WELL. SPC DOES COVER THE
ENTIRE REGION WITH THUNDER THU EVENING. WILL ADD THUNDER TO THE
FORECAST AS A RESULT.

STRONGER COLD AIR ADVECTION MOVES IN FOR LATE THU NIGHT AND
FRIDAY. I DOWNPLAYED THE POPS AS THE AIR COLD ENOUGH FOR LAKE
EFFECT IS HANGING BACK WELL BEHIND THE FRONT. THERE IS A
SUGGESTION OF A WAVE DEVELOPING ON THE FRONT FRIDAY SOUTH OF MI.
WILL NEED TO MONITOR THIS CLOSELY.

.LONG TERM...(SATURDAY THROUGH WEDNESDAY)
ISSUED AT 241 PM EDT WED OCT 3 2012

WEEKEND TO BE A COOL AND UNSETTLED ONE WITH LAKE EFFECT RAIN SHOWERS
WITH AN ISOLATED THUNDERSTORM STILL ON TRACK TO AFFECT SOUTHWEST
LOWER MICHIGAN.  HIGH TEMPERATURES BOTH SATURDAY AND SUNDAY STILL
LOOKING TO BE UPPER 40S TO MID 50S AT BEST...WITH OVERNIGHT LOW
TEMPERATURES GENERALLY IN THE MID 30S.

A BRIEF DRY PERIOD LOOKING POSSIBLE MONDAY INTO TUESDAY...WITH
TEMPERATURES REMAINING SLIGHTLY BELOW NORMAL FOR THIS TIME OF YEAR.
MORE UNSETTLED WEATHER RETURNS TUESDAY NIGHT WITH SHOWERS POSSIBLE
ACROSS THE REGION THROUGH WEDNESDAY INTO THURSDAY.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z THURSDAY AFTERNOON)
ISSUED AT 1213 PM EDT WED OCT 3 2012

CHALLENGING AVIATION FORECAST CENTERING AROUND CEILINGS THAT
SHOULD BE LOW MVFR TO IFR AND PERIODS OF MVFR/IFR VISIBILITIES IN
LIGHT DRIZZLE AND FOG. MVFR/IFR CONDITIONS SHOULD OCCUR THROUGH
MUCH OF THE FIRST 18 HOURS OF THE TAF PERIOD BEFORE CONDITIONS
BEGIN TO IMPROVE.

CEILINGS AND VISIBILITIES SHOULD SLOWLY TREND TOWARD VFR AFTER 06Z
THURSDAY...BUT SOME LINGERING FOG COULD KEEP CONDITIONS FROM
REACHING VFR UNTIL AFTER 12Z THURSDAY.

OTHER AVIATION CONSIDERATION FOR THE TAF PERIOD WILL BE THE
DEVELOPMENT OF GUSTY SOUTHWEST WINDS THAT SHOULD OCCUR FROM
NORTHWEST TO SOUTHEAST AROUND OR SHORTLY BEFORE 18Z. GUSTS UP TO
20KTS POSSIBLE AFTER 18Z.

&&

.MARINE...
ISSUED AT 241 PM EDT WED OCT 3 2012

INCREASING FLOW AHEAD OF THE COLD FRONT WARRANTS A SMALL CRAFT
ADVISORY FOR MUCH OF MY AREA BY 18Z THU. STRONGER COLD AIR
ADVECTION SETS UP LATER THU NIGHT AND FRIDAY. THIS WILL IMPACT ALL
NEARSHORE ZONES. MIXING HEIGHTS FROM BUFKIT SUGGEST 30 KNOT WINDS
ARE LIKELY. FOR NOW WILL HOLD OFF ON A GALE WATCH...THINKING THIS
WILL BE A HIGH END SCA EVENT FOR ALL NEARSHORE WATERS.

&&

.HYDROLOGY...
ISSUED AT 241 PM EDT WED OCT 3 2012

THE LIGHT RAIN WILL HAVE LITTLE IMPACT ON THE RIVERS THROUGH THE WEEKEND.
NO SIGNIFICANT RISES ARE FORECASTED.
