AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
328 PM EDT FRI APR 1 2016

LATEST UPDATE...
SYNOPSIS/SHORT TERM/LONG TERM/MARINE

.SYNOPSIS...
ISSUED AT 328 PM EDT FRI APR 1 2016

A COLD FRONT CROSSING THE AREA TONIGHT WILL BRING A PERIOD OF
SHOWERS THAT WILL MIX WITH AND CHANGE TO FLURRIES TOWARD MIDNIGHT.
A LOW PRESSURE SYSTEM FROM CANADA WILL TRACK ACROSS CENTRAL LOWER
MICHIGAN SATURDAY BRINGING A PERIOD OF SNOW SHOWERS... SOME LIGHT
ACCUMULATIONS ARE EXPECTED NORTH OF I-96. ANOTHER STRONG LOW
PRESSURE SYSTEM WILL TRACK ACROSS THE I-94 AREA SUNDAY EVENING.
THAT WILL BRING MIXED RAIN AND SNOW TO THE I-96 AREA... WITH
ACCUMULATING SNOW EXPECTED NEAR ROUTE 10.

&&

.SHORT TERM...(THIS EVENING THROUGH SUNDAY NIGHT)
ISSUED AT 328 PM EDT FRI APR 1 2016

THE BIGGEST ISSUE IS THE THREAT OF ACCUMULATING SNOW SATURDAY
AFTERNOON AND MORE SO SUNDAY AFTERNOON INTO SUNDAY NIGHT.
THE SYSTEM COMING THROUGH SATURDAY WILL TRACK JUST NORTH OF I-96.
THE AIR WILL BE COLD ENOUGH FOR ALL SNOW OVER SATURDAY BUT AREAS
SOUTH OF THE TRACK OF THE LOW MAY WARM ENOUGH TO RESULT IN MIXED
RAIN AND SNOW DURING THE AFTERNOON. SNOW AMOUNTS NORTH OF THE LOW
WILL BE IN THE 1 TO 2 INCH RANGE BUT BEING EARLY APRIL... THE
ACCUMULATIONS WILL MOSTLY BE IN WOODED AREA WELL AWAY FROM URBAN
CENTERS.

THE SYSTEM SUNDAY AFTERNOON INTO SUNDAY NIGHT HAS BETTER DYNAMICS
AND FGEN TO HELP THE CAUSE OF SNOW ACCUMULATING. ALSO THE SNOW
FALLING AFTER SUNSET HELPS TOO. I COULD SEE 3 TO 5 INCHES NEAR
ROUTE 10. BOTH THE ECMWF AND GFS ARE TRACKING THIS SYSTEM FARTHER
SOUTH AND THAT WOULD BRING THE AREA OF SIGNIFICANT SNOW FARTHER
SOUTH. THERE IS 60 KNOTS BLOWING 4 G/KG OF MOISTURE PERPENDICULAR
TO THE SURFACES SUNDAY AFTERNOON INTO SUNDAY EVENING. THAT IS WAY
MORE THAN ENOUGH TO GENERATE SHOVELABLE SNOW AMOUNTS. THAT PROCESS
IS FUELED BY FGEN THAT RESULTS FROM THE JET ENTRANCE REGION LIFT.
WE MAY NEED AN ADVISORY FOR THIS... LATER SHIFTS WILL HAVE TO
LOOK AT THIS.

IT WILL BE WINDY SOUTH OF THE TRACK OF THE SYSTEM SATURDAY BUT I
DO NOT THINK IT WILL BE WINDY ENOUGH FOR A WIND ADVIOSRY.

.LONG TERM...(MONDAY THROUGH FRIDAY)
ISSUED AT 328 PM EDT FRI APR 1 2016

THE PASSING SYSTEM SHOULD DRAG EVEN COLDER AIR DOWN FOR
MONDAY/MONDAY NIGHT.  H8 TEMPS BOTTOM OUT AROUND -14C MONDAY NIGHT.
THIS WILL LEAD TO SOME LAKE EFFECT SNOW...HOWEVER THE MOISTURE DOES
NOT APPEAR TOO DEEP AND WITH THE FLOW NNW...THE SNOW SHOWERS SHOULD
REMAIN LIGHT AND HUG THE COAST.  WE WILL HAVE TO MONITOR HOW COLD IT
BECOMES MONDAY NIGHT...WITH THE FRUIT CROP OF CONCERN.  WE SHOULD
DROP INTO THE TEENS FOR SEVERAL HOURS WHICH MAY BE A THREAT TO SOME
OF THE BUDDING CROP.  ONE POSSIBLE SAVING GRACE WOULD BE IF WE END
UP A BIT CLOUDIER THAN EXPECTED.

SLIGHTLY WARMER AIR MOVES IN BY TUESDAY NIGHT THROUGH WEDNESDAY
NIGHT AS A SOUTHERLY FLOW DEVELOPS BEHIND HIGH PRESSURE.  THIS FLOW
WILL BRING DEEP GULF MOISTURE BACK TO THE REGION.  WITH A COLD FRONT
COMING THROUGH WEDNESDAY EVENING...WE CAN EXPECT ANOTHER PERIOD OF
PCPN.  THE INITIAL PCPN SHOULD ARRIVE TUESDAY NIGHT AND IT SHOULD BE
COOL ENOUGH FOR SNOW.  BUT THEN IT SHOULD SWITCH OVER TO RAIN
WEDNESDAY.  ONCE THE FRONT IS THROUGH WE WILL PROBABLY END AS SNOW
WEDNESDAY NIGHT.

ANOTHER COLDER THAN NORMAL PERIOD WILL FOLLOW THIS SYSTEM FOR
THURSDAY AND FRIDAY...ALTHOUGH NOT AS COLD AS EARLIER IN THE WEEK.
IT APPEARS AN UPPER TROUGH WILL REMAIN OVER THE EASTERN U.S....SO
EXPECT SOME LIGHT SNOW FOR THURSDAY.  THEN SURFACE RIDGING SHOULD
MOVE IN FOR FRIDAY.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z SATURDAY AFTERNOON)
ISSUED AT 155 PM EDT FRI APR 1 2016

ACTIVE WEATHER OVER THE NEXT 24 HOURS. AS OF 18Z THE REGION WAS
LARGELY VFR WITH SOME VERY PATCHY MVFR CEILINGS. WE WILL TREND
TOWARD MORE VFR THROUGH THE AFTERNOON. WEST WINDS WILL REMAIN
AROUND 10 KNOTS THROUGH ABOUT 05Z...THEN DIMINISH.

A BAND OF RAIN...POSSIBLY MIXING WITH SNOW ALONG THE I-96
TAFS...WILL MOVE THROUGH THIS EVENING. THIS COULD BRING SOME MVFR
AT TIMES. THIS RAIN AND POSSIBLE MVFR WILL ONLY LAST 3 TO 4 HOURS
AT ANY ONE SITE...THEN WE BRIEFLY DRY OUT WITH VFR RETURNING.

FINALLY...AND MOST SIGNIFICANT...AN AREA OF SNOW WILL SETTLE INTO
THE REGION LATE SATURDAY MORNING. THIS WILL BRING A PERIOD OF IFR
AND POSSIBLE LIFR. ALONG WITH THE IFR/SNOW WILL COME STRONG WSW
WINDS THAT WILL GUST AS HIGH AS 30 KNOTS.

&&

.MARINE...
ISSUED AT 328 PM EDT FRI APR 1 2016

I WILL ISSUE A SMALL CRAFT ADVISORY FOR TONIGHT AND GALE WARNING
FOR SATURDAY. WINDS AND WAVES WILL BE LARGEST OVER THE SOUTHERN
SECTIONS OF OUR NEAR SHORE SATURDAY.

&&

CROTON DAM... THE MAPLE RIVER NEAR MAPLE RAPIDS AND THE ROGUE RIVER
