AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
645 AM EST FRI FEB 10 2012
LATEST UPDATE...AVIATION...
.SYNOPSIS...(346 AM EST FRI FEB 10 2012)
AN ARCTIC COLD FRONT WILL MOVE ACROSS LOWER MICHIGAN TODAY BRINGING
A BURST OF SNOW AND MUCH COLDER TEMPERATURES. DRIVING CONDITIONS
WILL LIKELY BE IMPACTED THIS AFTERNOON. COLDER WEATHER WILL LINGER
THROUGH THE WEEKEND BEFORE TEMPERATURES BEGIN CLIMBING BACK TO 40
MIDWEEK.
&&
.SHORT TERM...(346 AM EST FRI FEB 10 2012)
(TODAY THROUGH SUNDAY)
WE/RE RUNNING WITH A WINTER WX ADVISORY THIS AFTERNOON/EVENING FOR
ALL BUT THE NRN 2 ROWS OF COUNTIES. THIS WILL BE AN IMPACT DRIVEN
EVENT FEATURING 1-3 INCHES OF SNOW ALONG WITH RAPIDLY FALLING TEMPS
THIS AFTERNOON.
OF PARTICULAR CONCERN WILL BE TRAVEL CONDITIONS ALONG THE
INTERSTATES 96/94 AS THE HEAVIEST SNOW WILL COMMENCE IN THOSE
LOCATIONS AROUND MID AFTERNOON...AROUND THE TIME SCHOOLS ARE LETTING
OUT AND PEOPLE BEGIN TO HEAD HOME FROM WORK FOR THE WEEKEND. TEMPS
WILL BE IN THE 30S AHEAD OF THE FRONT. LATEST HRRR INDICATES THAT
SOME LIGHT SNOW MAY BEGIN PRIOR TO FROPA. THIS WILL RESULT IN SOME
MELTING ON ROADWAYS WHICH WILL QUICKLY FREEZE BEHIND THE FRONT.
ADDITIONALLY...MUCH OF THE OMEGA IS JUST BELOW THE DGZ SUGGESTING
THAT FLAKE SIZE WILL BE SMALL. SMALL FLAKES COMBINED WITH A FREEZING
ROAD SFC WILL CREATE ICY CONDITIONS. NORTH WINDS GUSTING TO 25-30
MPH WILL ALSO CREATE STRONG CROSS WINDS ON THE E/W INTERSTATES
FURTHER REDUCING VSBYS. ALL OF THESE FACTORS COMBINED WITH THE
TRANQUIL WX WE/VE SEEN RECENTLY MAY CATCH PEOPLE OFF GUARD AND
RESULT IN NUMEROUS SLIDE OFFS. THUS WE FELT IT PRUDENT TO HIGHLIGHT
THIS EVENT WITH AN ADVISORY.
THE SNOW WILL DIMINISH A FEW HOURS AFTER FROPA. THIS DOES/T LOOK
LIKE A BIG LAKE EFFECT PRODUCER FOR US. BOUNDARY LAYER WINDS BECOME
NNE TONIGHT RESULTING IN A DOMINANT BAND FROM JUST OFF SHORE
LUDINGTON SSW TO NEAR CHICAGO. IT REMAINS POSSIBLE THAT THE MAIN
BAND COULD CLIP THE POINTS AND WE/LL KEEP AN EYE ON THAT.
INLAND...NORTH WINDS SHOULD LEAD TO SOME CLEARING.
WINDS BEGIN TO BACK TO THE NW SATURDAY AS WARM AIR ADVECTION BEGINS.
THIS WILL CAUSE SHSN OVER THE LAKE TO MOVE INLAND. THE LAKESHORE
AREAS SOUTH OF GRAND HAVEN HAVE THE BEST CHANCE AT SEEING UP TO AN
INCH. PCPN WILL DIMINISH SATURDAY NIGHT AND SUNDAY LOOKS DRY AS
TEMPS CLIMB BACK UP TO 30.
&&
.LONG TERM...(346 AM EST FRI FEB 10 2012)
(SUNDAY NIGHT THROUGH THURSDAY)
THE MAIN CHALLENGE IN THE LONG TERM DEALS WITH THE SNOW AMOUNTS FOR
MONDAY INTO TUESDAY.
MODELS ARE TRENDING TOWARD A FASTER AND WEAKER SYSTEM FOR THIS TIME
FRAME. MODELS ARE IN DECENT AGREEMENT IN SHOWING WEAK LIFT BUT
DECENT MOISTURE DEPTH ESPECIALLY MON NIGHT. AT THIS POINT WILL KEEP
POPS UNDER LIKELY AS THE TREND HAS BEEN FOR A WEAKER SYSTEM. THE
DGZ BECOMES UNSATURATED TUESDAY...THUS THE POTENTIAL FOR MEASURABLE
AMOUNTS DROPS OFF.
HIGH PRESSURE MOVES IN FOR WED. THAT WILL LIMIT THE RISK FOR
PRECIPITATION. HOWEVER ANOTHER STORM SYSTEM WILL RIDE UP THE OH
VALLEY ON THU. THIS COULD LEAD SOME SNOW FOR SW LOWER MI.
&&
.AVIATION...(645 AM EST FRI FEB 10 2012)
A BAND OF SNOW WILL DROP SOUTHEAST THROUGH THE TAF SITES LEADING TO
IFR CONDITIONS BEGINNING LATER THIS MORNING AND CONTINUING INTO THE
AFTERNOON. CONDITIONS COULD TEMPORARILY GO TO LIFR THIS AFTERNOON.
WINDS WILL INCREASE LATER THIS AFTERNOON AND EVENING AND GUSTS OVER
25 KNOTS FROM THE NORTH ARE FORECASTED FOR THE TAF SITES. THE
DEEPER MOISTURE PULLS AWAY FOR LATE TONIGHT AND THAT SHOULD SHUT
DOWN MOST OF THE SNOW...BUT MVFR CLOUDS WILL PREVAIL.
&&
.MARINE...(346 AM EST FRI FEB 10 2012)
WE/LL SEE AN ABRUPT WIND SHIFT TODAY AS A STRONG COLD FRONT MOVES
THROUGH. WINDS WILL GUST FROM THE NORTH BEHIND THE FRONT TO JUST
UNDER GALE FORCE AND THEN DIMINISH OVERNIGHT. AS TEMPS FALL BELOW
FREEZING LATER THIS AFTERNOON AND TONIGHT...THE GUSTY WINDS MAY
RESULT IN FREEZING SPRAY.
&&
.HYDROLOGY...(346 AM EST FRI FEB 10 2012)
MINIMAL HYDRO CONCERNS. A COUPLE OF INCHES OF SNOW IS EXPECTED WITH
THE STRONG FRONT TODAY BUT THAT WILL HAVE A LIMITED IMPACT ON AREA
RIVERS. THE ARCTIC AIR THAT OVERSPREADS THE REGION THIS WEEKEND
LIKELY WON/T LAST LONG ENOUGH TO CREATE ICE JAM ISSUES.
&&
.GRR WATCHES/WARNINGS/ADVISORIES...
MI...WINTER WEATHER ADVISORY THIS AFTERNOON AND EVENING FOR ALL BUT
THE NORTHERN TWO ROWS OF COUNTIES.
