AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
330 AM EST WED DEC 23 2015

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

.SYNOPSIS...
ISSUED AT 330 AM EST WED DEC 23 2015

A VERY ACTIVE WEATHER PATTERN WILL PLAY OUT OVER THE NEXT 24 HOURS.
WE WILL SEE AN AREA OF RAIN AND POSSIBLE THUNDERSTORMS MOVE THROUGH
LATE THIS AFTERNOON INTO THIS EVENING.  THESE STORMS COULD CONTAIN
STRONG WINDS.  THE WINDS WILL REMAIN STRONG INTO THU MORNING...
OCCASIONALLY GUSTING AS HIGH AS 45 MPH.  THE WEATHER CALMS DOWN
THURSDAY AFTERNOON.  THERE COULD BE WIDELY SCATTERED RAIN OR SNOW
SHOWERS NORTH OF I-96 THURSDAY AS COOLER AIR MOVES IN.  CHRISTMAS
DAY LOOKS QUIET WITH MILD TEMPERATURES OF 40 TO 45.

THE WEEKEND INTO NEXT WEEK STILL LOOKS WARMER THAN NORMAL WITH
TEMPERATURES STILL MAINLY 40 TO 45.  MORE RAIN IS POSSIBLE SATURDAY
AND SATURDAY NIGHT...WITH MIXED PRECIPITATION BY MONDAY NIGHT.

&&

.SHORT TERM...(TODAY THROUGH FRIDAY)
ISSUED AT 330 AM EST WED DEC 23 2015

ACTIVE WEATHER TODAY AND TONIGHT AS DEEP GULF MOISTURE MOVES OVER
HEAD ALONG WITH STRONG JET DYNAMICS.

AREAS OF SOUTH OF I-96 HAVE BEEN PUT INTO THE SLIGHT RISK AREA.  THIS
AREA WILL SEE THE INFLUENCE OF A STRONG LOW LEVEL JET THAT ARRIVES
LATE THIS AFTERNOON INTO THIS EVENING.  SHEAR VALUES SUPPORT SOME
STRONG STORMS AND WITH DEW POINTS IN THE MID 50S WE SHOULD REALIZE
SOME INSTABILITY.  BIGGEST THREAT WITH THESE STORMS WILL BE DAMAGING
WINDS...BUT AN ISOLATED TORNADO CAN NOT BE RULED OUT.

THE STORMS SHOULD LARGELY BE THROUGH BY MIDNIGHT.  THEN THE STRONG
SYNOPTIC WINDS KICK IN WITH THE ARRIVAL OF THE COLD ADVECTION.  WILL
GO WITH A WIND ADVISORY IN THIS TIME PERIOD...LATE TONIGHT THROUGH
THURSDAY MORNING...WHEN GUST COULD REACH 45-50 MPH.

THE UPPER WAVE SHEARS OUT...BUT MAY STILL PRODUCE A LIGHT MIX OF
RAIN AND SNOW ON THURSDAY.  NO SNOW ACCUMS ARE EXPECTED.

THE WEATHER DIES DOWN SIGNIFICANTLY BY CHRISTMAS EVE AND DAY WITH
HIGH PRESSURE MOVING INTO THE WESTERN GREAT LAKES BY DAYBREAK
CHRISTMAS.

.LONG TERM...(FRIDAY NIGHT THROUGH TUESDAY)
ISSUED AT 330 AM EST WED DEC 23 2015

MILD PATTERN CONTINUES THROUGH THE HOLIDAY WEEKEND... WITH ANOTHER
RAIN SYSTEM TRACKING THROUGH THE GREAT LAKES REGION ON SATURDAY AND
SATURDAY NIGHT.

BEHIND THAT SYSTEM A COOLER AND DRIER AIR MASS ARRIVES FROM THE
NORTH FOR SUNDAY AND MONDAY AS A SFC HIGH DRIFTS EAST ACROSS SRN
ONTARIO AND INTO QUEBEC.

TIMING DIFFERENCES EXIST REGARDING THE NEXT SRN STREAM SYSTEM EARLY
NEXT WEEK WITH THE GFS BRINGING PRECIP IN ON MONDAY BUT THE ECMWF
HOLDING IT OFF UNTIL LATE MONDAY NIGHT AND TUESDAY.

WHILE THE SYSTEM EARLY NEXT WEEK LOOKS PRIMARILY LIKE ANOTHER RAIN
SYSTEM... WE WILL HAVE TO MONITOR THE POTENTIAL FOR SOME FREEZING
RAIN AND SLEET/SNOW AT THE ONSET SINCE A COLD/DRY LOW LEVEL AIR MASS
RELATED TO THE SFC HIGH TO OUR NORTH WILL BE IN PLACE AS THE PRECIP
ARRIVES.

&&

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z WEDNESDAY NIGHT)
ISSUED AT 1142 PM EST TUE DEC 22 2015

SOUNDINGS INDICATE LOW LEVEL MOISTURE WILL INCREASE AFTER 06Z
CONTRIBUTING TO IFR CIGS OVERNIGHT. SHOWERS AND STRONGER SOUTH
WINDS WILL DEVELOP LATER WEDNESDAY AND A THUNDERSTORM IS POSSIBLE
TOO, THOUGH WE DIDN'T INCLUDE TSRA IN THE TAFS AS INSTABILITY IS
MARGINAL.

&&

.MARINE...
ISSUED AT 330 AM EST WED DEC 23 2015

WILL UPGRADE THE GALE WATCH INTO A WARNING THE WILL START THIS
EVENING.  THIS APPEARS TO BE A HIGH END GALE...WITH WINDS AS HIGH AS
45 KNOTS DEVELOPING LATE TONIGHT.  WINDS WILL GRADUALLY SIMMER DOWN
THROUGH THURSDAY...SO THE GALE WARNING GOES THROUGH MID DAY THURSDAY.

&&

.HYDROLOGY...
ISSUED AT 225 PM EST TUE DEC 22 2015

RIVERS ARE STAYING BELOW BANKFULL AFTER MONDAYS RAIN. THE HEAVIEST
RAIN FELL IN LOCATIONS THAT ARE GENERALLY NOT PROBLEMATIC IN TERMS
