.SYNOPSIS...(340 PM EST THU DEC 22 2011)
WATCH OUT FOR THE POSSIBILITY OF BLACK ICE ON UNTREATED ROADS LATER
TONIGHT AS TEMPERATURES DROP BELOW FREEZING AFTER LIGHT RAIN OR A
MIXTURE OF LIGHT RAIN AND SNOW FALLS AND DAMPENS THE ROADS.

THE HIGHEST RISK OF BLACK ICE DEVELOPING IS ACROSS THE AREA FROM
GRAND RAPIDS TO THE SOUTH AND EAST AS A STRONG SYSTEM TRACKS SOUTH
OF THE STATE. A COLD FRONT COMING DOWN FROM THE NORTH WILL SEND IN
THE SUB FREEZING AIR FOR LATER TONIGHT.

OUR NEXT WEATHER MAKER IS A LOW PRESSURE AREA AND ATTENDANT COLD
FRONT WHICH TRACKS ACROSS THE NORTHERN GREAT LAKES REGION FRIDAY
NIGHT. THIS FEATURE WILL PRODUCE A BRIEF PERIOD OF SCATTERED TO
NUMEROUS SNOW SHOWERS MAINLY FROM GRAND RAPIDS NORTH AND WEST. THERE
COULD BE AN INCH OR SO OF SNOW ACCUMULATION.

&&

.SHORT TERM...(340 PM EST THU DEC 22 2011)
(TONIGHT THROUGH SATURDAY NIGHT)
LIGHT SNOW WHICH FLARED UP IN THE PRE DAWN HOURS ACROSS THE FAR NRN
CWFA ALONG THE SWD MOVING SFC COLD FRONT DISSIPATED THIS MORNING.
HOWEVER ANOTHER FLARE UP IN LIGHT PRECIPITATION IS ANTICIPATED LATE
THIS AFTERNOON AND THIS EVENING 22Z-06Z... MAINLY FROM GRR TO THE
SOUTH AND EAST... AS YET ANOTHER POTENT SRN STREAM WAVE PASSES WELL
SOUTH OF THE STATE.

MODELS SUGGEST ONLY TRACE TO 0.10 AMOUNTS THROUGH 06Z... BUT THERE
IS REASON TO BELIEVE THIS COULD HAVE IMPACTS FOR THE I-96/I-94
CORRIDOR REGIONS. FCST SOUNDINGS SUGGEST THAT THE BULK OF THE PCPN
IS GOING TO FALL IN THE FORM OF LIGHT RAIN OR A MIXTURE OF LIGHT
RAIN AND SNOW INITIALLY WITH SFC TEMPS IN THE MID TO UPPER 30S THIS
EVENING. THEN A CHANGEOVER TO ALL SNOW IS LIKELY BEFORE ENDING
TOWARD OR SHORTLY AFTER MIDNIGHT.

CONFIDENCE IS EXTREMELY HIGH THAT SFC TEMPS WILL FALL BELOW FREEZING
DURING OR JUST AFTER THE ROADS HAVE BEEN DAMPENED BY THE LIGHT
PRECIP... BETWEEN 10 PM AND 1 AM. THIS COULD LEAD TO A BLACK ICE
SITUATION...WITH PERHAPS HIGHER THAN AVERAGE TRAFFIC VOLUMES
EXISTING DUE TO HOLIDAY TRAVEL/SHOPPING.

AM SOMEWHAT RELUCTANT TO ISSUE AN IMPACT ADVISORY FOR A BLACK ICE
SITUATION ATTM SINCE AM NOT HIGHLY CONFIDENT ON THE OVERALL AREAL
COVERAGE AND AMOUNTS OF PCPN PRIOR TO THE ARRIVAL OF THE SUB
FREEZING AIR. HOWEVER A SPECIAL STATEMENT WAS ISSUED DESCRIBING THE
POTENTIAL THREAT. IT IS LOOKING NOW THAT THE PRIMARY AREA OF CONCERN
IS FROM GRR TO THE SOUTH AND EAST... AND MOSTLY AFTER 10 PM.

NEXT PERIOD OF WEATHER IS FRIDAY NIGHT WHEN THE NEXT NRN STREAM
SHORTWAVE AND SFC COLD FRONT SCOOTS THROUGH THE REGION. BURST OF
PVA/LIFT IS RELATIVELY SHORT LIVED BUT A PERIOD OF DECENT SNOW
SHOWERS IS LIKELY WHICH COULD PRODUCE A QUICK INCH OR SO OF
ACCUMULATION MAINLY IN THE NW CWFA AROUND LUDINGTON WHERE MOISTURE
AND LIFT LOOKS BEST...AND A RESPECTABLE DGZ/OMEGA CROSS HAIR
SIGNATURE EXISTS BETWEEN 5K AND 10K FEET.

&&

.LONG TERM...(340 PM EST THU DEC 22 2011)
(CHRISTMAS DAY THROUGH THURSDAY)
THE MAIN FOCUS OF THE FCST IS CENTERED ON PCPN CHCS FOR CHRISTMAS
DAY AND TUE AS A COUPLE OF SHORT WAVES/PV ANOMALIES EMBEDDED IN THE
NORTH BRANCH OF THE JET APPROACH THE AREA.

WE MAINTAINED THE CHC OF SNOW SHOWERS FOR THE CHRISTMAS DAY PERIOD.
MODELS ARE PRETTY CONSISTENT IN SHOWING A WAVE MOVING THROUGH. THE
TREND HAS BEEN FOR THE WAVE TO DIG SOUTH JUST A LITTLE MORE WITH THE
JET CORE ACTUALLY ENDING UP NOW NEAR THE SRN CWFA BORDER. MODELS ARE
STILL SOMEWHAT DRY WITH REGARDS TO QPF...HOWEVER THE JET CORE BEING
SOUTH OF THE CWFA JUSTIFIES THE CHC POPS.

THIS WAVE WILL QUICKLY MOVE OUT...AND A SOLID RETURN FLOW WILL SET
UP ALLOWING FOR WARMING TO TAKE PLACE ON MON. H850 TEMPS ARE
EXPECTED TO RISE TO AROUND 4C...ALTHOUGH THIS WILL NOT MIX DOWN TO
THE SFC. THE NEXT UPPER WAVE IN THE SEQUENCE IS THEN EXPECTED TO
ARRIVE FOR THE TUE TIME FRAME. THIS WILL BRING A CHC OF SOME LIGHT
PCPN. IT IS INTERESTING TO NOTE THAT THE 00Z AND 12Z RUNS OF THE
EURO HAVE BEEN FLIP-FLOPPING. THE SRN STREAM SYSTEM APPROACHING THE
AREA ON TUE IN THE 12Z EURO LIKE THE 12Z RUN YESTERDAY...IS TOTALLY
DIFFERENT THAN THE 00Z RUN. THE NRN STREAM FRONT WITH LITTLE PCPN
LOOKS MORE LIKELY TO OCCUR...ALTHOUGH TUE IS COVERED IF BY CHC THE
SRN STREAM SYSTEM ENDS UP PANNING OUT.

A COUPLE OF MORE WAVES WILL BE POSSIBLE THEN FOR WED AND/OR THU.
HOWEVER THE MODELS DISAGREE AS EXPECTED WITH THESE WAVES. THEY ARE
LOW AMPLITUDE...AND THE MODELS ARE FAIRLY DRY FOR THE AREA
REGARDLESS...SO WE WILL GO DRY FOR NOW AND CONTINUE TO MONITOR
TRENDS.

&&

.AVIATION...(1205 AM EST FRI DEC 23 2011)
FAIRLY QUIET 24 HOURS FOR THIS TIME OF YEAR FOR THE 06Z SET OF TAFS.
SNOW IS EXITING THE SOUTHEAST PORTION OF THE FORECAST AREA AT THIS
TIME...WITH KJXN STILL REPORTING A LITTLE LIGHT SNOW. THIS SHOULD
END IN THE NEXT HOUR. OTHERWISE...MVFR CEILINGS WILL LIFT TO VFR
TONIGHT. VFR CONDITIONS SHOULD PREVAIL THROUGH THE DAY ON FRIDAY.
THE NEXT THREAT FOR ANY PRECIPITATION OR LOWER CEILINGS COMES FRIDAY
EVENING AFTER DARK AT KMKG. BROUGHT IN A LITTLE BIT OF LIGHT SNOW AT
THIS POINT WITH A VFR DECK. IT MAY TREND INTO THE MVFR CATEGORY
AFTER 03Z...BUT NOT CONFIDENT ENOUGH TO PUT IT INTO THE FORECAST AT
THIS POINT.

&&

.MARINE...(340 PM EST THU DEC 22 2011)
NORTHERLY WINDS WILL INCREASE TONIGHT AS THE COLD FRONT PASSES. IT
WILL BE A 360-030 WIND... SO AREAS BETWEEN WHITEHALL AND HOLLAND
WILL BE SHELTERED FROM STRONGER WINDS AND HIGHER WAVES. SCA
CONTINUES FOR THE NRN AND SRN NEARSHORE AREAS THROUGH FRIDAY
MORNING.

&&

.HYDROLOGY...(340 PM EST THU DEC 22 2011)
MAINSTEM RIVER STAGES ARE STILL EXPECTED TO GRADUALLY DECREASE GIVEN
VERY LITTLE QPF OVER THE NEXT FEW DAYS.

.GRR WATCHES/WARNINGS/ADVISORIES...

LM...SMALL CRAFT ADVISORY WHITEHALL TO MANISTEE AND ST. JOSEPH TO
