AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
329 AM EST MON JAN 5 2015

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

.SYNOPSIS...
ISSUED AT 329 AM EST MON JAN 5 2015

COLD AIR AND LAKE EFFECT SNOW SHOWERS WILL BE THE RULE FOR THE AREA
FOR MOST OF THE NEXT WEEK. WAVES OF LOW PRESSURE MOVING THROUGH THE
AREA WILL HELP TO ENHANCE THE SNOW SHOWERS AT TIMES THROUGH THE
PERIOD.

&&

.SHORT TERM...(TODAY THROUGH WEDNESDAY)
ISSUED AT 329 AM EST MON JAN 5 2015

WE ARE TRANSITIONING OUR HEADLINES IN ANTICIPATION OF THE LAKE
ENHANCED CLIPPER SYSTEM THAT WILL AFFECT THE AREA FOR TONIGHT AND
EARLY ON TUESDAY. THE WESTERN HALF OF THE CWFA WILL HAVE THE
ADVISORY EXTENDED IN TIME THROUGH NOON ON TUESDAY THAT WILL REPLACE
THE WINTER STORM WATCH. CALHOUN COUNTY WILL BE TAKEN OUT OF THE
WINTER WEATHER ADVISORY AND PUT INTO THE WIND CHILL ADVISORY.

WE ARE EXPECTING LAKE EFFECT TO REMAIN RATHER LIMITED TODAY. WE ARE
INDEED SEEING THE ACCUMULATION POTENTIAL BEING LIMITED THIS MORNING
BY THE LACK OF DGZ IN THE CLOUD LAYER AND WITH THE INVERSION HEIGHTS
AOB 5K FT. WE WILL CONTINUE TO SEE SNOW SHOWERS THROUGHOUT THE DAY.
THE SNOWFLAKE SIZE WILL REMAIN SMALL SO THAT THE SNOW WILL NOT
ACCUMULATE WELL. SOME BLOWING AND DRIFTING WILL CONTINUE THIS
MORNING ALONG THE WRN HALF OF THE CWFA BEFORE WINDS DIMINISH A BIT
THIS AFTERNOON.

WE WILL BE LEAVING THE WIND CHILL ADVISORY IN EFFECT THIS MORNING
FOR THE ERN HALF OF THE CWFA. WIND CHILLS ARE DOWN IN THE -10 TO
-20F RANGE THIS MORNING. TEMPS WILL NOT WARM MUCH IF ANY
TODAY...HOWEVER WINDS DIMINISHING WILL ALLOW WIND CHILLS TO IMPROVE
A LITTLE AND ABOVE CRITERIA.

THE MAIN SHOW IN THE SHORT TERM WILL BE THE CLIPPER SYSTEM THAT WILL
MOVE SOUTH OF LOWER MICHIGAN FROM TONIGHT INTO TUE MORNING. THIS
CLIPPER WILL HAVE RATHER LIMITED IMPACTS BY ITSELF AS THE BULK OF
THE SNOW WILL REMAIN SOUTH OF THE STATE LINE WHERE THE BEST FGEN IS
WITH THE UPPER WAVE AND THE POSITION RELATIVE TO THE SFC LOW. WE
WILL SEE SOME SNOW WITH IT...WITH HIGHER AMOUNTS DOWN SOUTH AND
LESSER AMOUNTS NORTH.

THE EXCEPTION TO THE LIMITED IMPACTS WITH THE CLIPPER WILL BE ALONG
THE LAKESHORE...ESPECIALLY FOR ALLEGAN...OTTAWA...MUSKEGON...AND
PORTIONS OF KENT COUNTY. ALL OF THE HIGH RES MODELS INDICATE AN
ENHANCED CONVERGENCE BAND THAT SETS UP INITIALLY FROM HOLLAND TO SRN
MUSKEGON AND NW KENT COUNTY TOWARD 03Z. THIS BAND WILL THEN SLOWLY
SHIFT SE THROUGH 15Z TUE AND WEAKEN AS THE SW FLOW AHEAD OF THE
CLIPPER BECOMES NW BEHIND IT TUE MORNING. CONDITIONS BECOME
FAVORABLE FOR ENHANCED SNOW AS THE DGZ MAKES IT INTO THE CLOUD
LAYER...MOISTURE IS UP THROUGH 20K FEET AND...INVERSION HEIGHTS LIFT
TO AROUND 10K FT+.

WE BELIEVE THAT THE FAVORED AREA WILL SEE SOLID ADVISORY CONDITIONS
AND IMPACTS. THE REMAINDER OF THE WRN AREA WILL SEE MORE MARGINAL
TYPE ADVISORY CONDITIONS. THERE IS A CHC THAT SOME LOCAL FAVORED
AREAS MAY SEE CONDITIONS APPROACH WARNING TYPE IMPACTS. WE BELIEVE
THE TRANSITORY NATURE OF THE BAND SHOULD KEEP ANY ONE AREA FROM
SEEING TOO MUCH SNOW IN THE SHORT PERIOD...BUT WE CAN NOT RULE THIS
OUT.

ONCE THE CLIPPER MOVES OUT BY TUE AFTERNOON...WE WILL SEE CONDITIONS
SIMILAR TO THIS MORNING WITH REGARD TO SNOW SHOWER INTENSITY.
ANOTHER REINFORCING SHOT OF COLD AIR WILL MOVE IN AND DRIVE THE DGZ
INTO THE SUB-CLOUD LAYER FOR LATE TUE AND TUE NIGHT. INVERSION
HEIGHTS LIFT A BIT ON WED WITH SHORT WAVE ACTIVITY DROPPING SE INTO
THE AREA. THE FLOW WILL TRANSITION FROM WRLY ON TUE TO MORE NNW TUE
NIGHT AND EARLY WED. THIS WILL HELP THE LAKE EFFECT MIGRATE BACK
CLOSER TO THE COAST.

.LONG TERM...(WEDNESDAY NIGHT THROUGH SUNDAY)
ISSUED AT 329 AM EST MON JAN 5 2015

THE COLD AIR WILL REMAIN IN PLACE THROUGH THE END OF THE WORK
WEEK...WITH A SLIGHT MODERATION IN TEMPS EXPECTED OVER THE WEEKEND.
HIGHS THURSDAY AND FRIDAY WILL REMAIN IN THE TEENS...WHICH IS ABOUT
15 DEGREES BELOW NORMAL. SATURDAY WE WILL MODERATE TO NEAR 20 AND
THEN INTO THE 20S FOR SUNDAY.

LAKE EFFECT SNOW WILL CONTINUE THROUGH THE PERIOD AS WE HANG ON TO
AIR COLD ENOUGH ALOFT TO KEEP THE LAKE SNOW MACHINE GOING. MAIN
FOCUS IS ALWAYS ON THE TIME FRAMES WHERE LAKE SNOWS WILL BE ENHANCED
BY SHORTWAVE TROUGHS WHICH PROVIDE ADDITIONAL LIFT AND MOISTURE TO
THE LAKE BOUNDARY LAYER. THE TIME FRAME OF CONCERN WILL BE THURSDAY
INTO THURSDAY NIGHT AS A STRONG SHORTWAVE PIVOTS THROUGH THE GREAT
LAKES REGION.

LAKE EFFECT INTO THE WEEKEND BEHIND THIS WAVE LOOKS MARGINAL AS
850MB TEMPS WARM...LOWERING INSTABILITY. NO SIGNIFICANT SHORTWAVES
TO KEY ON EITHER.

SO...LAKE SNOWS LOOK SOLID WEDNESDAY NIGHT THROUGH FRIDAY NIGHT WITH
AN ENHANCED PERIOD THURSDAY AND THURSDAY NIGHT. SNOW TOTALS WILL
CONTINUE TO ADD UP TOWARDS LAKE MICHIGAN.

&&

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z MONDAY NIGHT)
ISSUED AT 1201 AM EST MON JAN 5 2015

HIGHLY VARIABLE CONDITIONS OVERNIGHT WITH THIN BANDS OF LAKE
EFFECT SNOW WILL DROP VISIBILITIES OCCASIONALLY DOWN TO 3/4 SM TO
1 1/2 SM. SOMEWHAT IMPROVED CONDITIONS EXPECTED STARTING AROUND
08Z BUT MORE LIKELY 12Z AND LATER AS INVERSION HEIGHTS AROUND 4K
FT SHOULD LIMIT THE SNOW BAND INTENSITIES. WIDESPREAD LIGHT TO
MODERATE SNOW (PERHAPS HEAVY IN MKG) SHOULD MOVE IN AROUND 03Z TUE
WHICH IS EXPECTED TO BRING ALL SITES TO IFR WELL INTO THE 06Z TUE
TO 12Z TUE TIME FRAME.

&&

.MARINE...
ISSUED AT 248 PM EST SUN JAN 4 2015

HEAVY FREEZING SPRAY AND GALE FORCE WINDS TO CONTINUE THROUGH
TONIGHT AND INTO MONDAY MORNING. WINDS WILL WEAKEN FOR MONDAY
NIGHT...BUT INCREASE AGAIN BY WEDNESDAY. FREEZING SPRAY ISSUES
COULD RESUME THEN.

ISSUED AT 248 PM EST SUN JAN 4 2015
