AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
329 PM EST SAT JAN 3 2015

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

.SYNOPSIS...
ISSUED AT 312 PM EST SAT JAN 3 2015

A LOW PRESSURE SYSTEM DEVELOPING IN OKLAHOMA WILL TRACK THROUGH
LOWER MICHIGAN LATE TONIGHT AND SUNDAY MORNING. THIS SYSTEM WILL
CREATE A MIX OF PRECIPITATION LEADING TO SLICK CONDITIONS. ARCTIC
AIR MOVES IN BEHIND THE DEPARTING SYSTEM AND REMAINS OVER THE
GREAT LAKES REGION FOR MUCH OF NEXT WEEK. BITTER COLD AIR AND
NUMEROUS SNOW SHOWERS WILL LEAD TO IMPACTS.

&&

.SHORT TERM...(THIS EVENING THROUGH MONDAY)
ISSUED AT 312 PM EST SAT JAN 3 2015

CHALLENGING FORECAST THE NEXT FEW DAYS.

TO START I WAS GOING TO CANCEL THE ADVISORY FOR MY SOUTHERN
COUNTIES. HOWEVER WHEN I SPOKE TO VAN BUREN DISPATCH...THEY
INDICATED THAT MANY REPORTS WERE STILL COMING EVEN...EVEN WITH AIR
TEMPERATURES GENERALLY ABOVE FREEZING. WITH THE IMPACTS
CONTINUING...I WILL LET THE ADVISORY RUN TIL 00Z THIS EVENING FOR
SOUTHERN PARTS OF MY AREA. WE MAY ALREADY BE COLD AIR ADVECTING
FOR SOUTH HAVEN AND GRAND RAPIDS. AIRCRAFT SOUNDINGS ACTUALLY SHOW
TEMPERATURES COOLING IN THE WARM LAYER...SLIGHTLY...PLUS MIXED
PRECIP AT LWA RECENTLY. THE DEEPER MOISTURE DOES DIMINISH THIS
EVENING...SO WE SHOULD SEE AN PERIOD OF L-/ZL-. BASED ON REPORTS
AND RADAR DATA...IT APPEARS THAT 3 TO 5 INCHES OF SNOW HAS ALREADY
FALLEN FOR PARTS OF MECOSTA AND ISABELLA COUNTIES. WITH MORE SNOW
ON THE WAY...I BUMPED UP TOTAL AMOUNTS FOR THE NORTHERN ADVISORY
AREA. SOME LOCATIONS MAY TOP OUT CLOSE TO 7 INCHES. I DID EXTEND
THIS NORTHERN ADVISORY TO 18Z AS THE DEEPER MOISTURE DOES NOT
DEPART UNTIL THEN.

WE MAY NEED TO EXPAND THE ADVISORY/ISSUE A NEW ONE FURTHER SOUTH
ALONG THE LAKESHORE FOR SUNDAY. THE WRAP AROUND MOISTURE COMBINES
WITH LAKE ENHANCED MOISTURE TO FOCUS MORE SNOW IN THE SOUTH HAVEN
TO HOLLAND AREA. THE COMBINATION OF THE SNOW AND INCREASING WINDS
MAY LEAD TO IMPACTS.

SUNDAY NIGHT INTO MONDAY THE DGZ DROPS DOWN TO THE GROUND. THIS
SHOULD ACT TO LIMIT ADDITIONAL SNOW AMOUNTS. THE SMALL FLAKES COULD
MAKE IT SLICK...ESPECIALLY WITH TEMPERATURES FALLING INTO THE
SINGLE DIGITS. WIND CHILL VALUES WILL DROP DOWN BELOW ZERO. WE
COULD END UP WITH AN AREA WIDE HEADLINE FOR THESE CONDITIONS.

.LONG TERM...(MONDAY NIGHT THROUGH SATURDAY)
ISSUED AT 312 PM EST SAT JAN 3 2015

STILL EXPECT A CLIPPER COMING DOWN FOR MONDAY NIGHT AND EARLY
TUESDAY.  THIS IS AN OPEN WAVE ALOFT AND FAIRLY PROGRESSIVE WHICH
SOMETIMES RESULTS IN LESS PCPN.  HOWEVER WITH THE ARCTIC AIR IN
PLACE...HIGH INVERSION LEVELS...AND DEEP MOISTURE THROUGH THE
DGZ...STILL EXPECT THIS SYSTEM WILL LIKELY OVER-PERFORM.  THE BEST
LAKE ENHANCEMENT MONDAY NIGHT WILL BE FROM SOUTH HAVEN NORTHWARD
WITH A WSW FLOW AND IT SHOULD CARRY A COUPLE COUNTIES INLAND.  THEN
AS THE SYSTEM BEGINS TO PULL AWAY ON TUESDAY WE MAY SEE A I-96
DOMINATE BAND SET UP AS WINDS TURN WESTERLY.  INVERSION HEIGHTS
APPEAR TO GRADUALLY LOWERING...SO ITS UNCLEAR HOW INTENSE THE SNOW
BANDS MAY BE INTO TUESDAY AFTERNOON.  ALL-IN-ALL EXPECT THIS CLIPPER
WILL PUT DOWN 3 TO 8 INCHES OF SNOW...HIGHEST AMOUNTS WEST OF U.S.
131.

BEHIND THE CLIPPER H8 TEMPS DIVE DOWN TO AROUND -25C BY WEDNESDAY
MAKING FOR A BRUTALLY COLD DAY.  ACTUAL TEMPS SHOULD ONLY PEAK
AROUND 10 ABOVE...BUT WITH 10 TO 15 MPH NW WINDS...WIND CHILL
READINGS WILL BE AROUND 10 BELOW MOST OF THE DAY.  THE LAKE EFFECT
SHOULD CONTINUE...BUT IT WILL BE THE FINE/POWDERY SNOWFLAKES THAT
MAY ONLY ADD ANOTHER 1 TO 4 INCHES TUESDAY NIGHT AND WEDNESDAY.

ANOTHER CLIPPER ARRIVES THURSDAY NIGHT...HOWEVER THE CORE OF THIS
ONE APPEARS TO REMAIN TO OUR NORTH...OVER NORTHERN LOWER OR EVEN THE
U.P.  EXPECT THE LES TO CONTINUE WED NIGHT THROUGH THURSDAY NIGHT
WITH A PERK UP THU NIGHT.

THERE IS POOR AGREEMENT IN THE MODELS FROM THU NIGHT INTO SAT.  WE
SHOULD GRADUALLY MODERATE FROM THE ARCTIC AIR LATE IN THE WEEK...BUT
HOW QUICKLY THIS HAPPENS AND HOW THIS EVOLVES IS A BIT UNCERTAIN.
LOOKS LIKE WE COULD HAVE SOME WARM ADVECTION TYPE SNOW IN HERE BY

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z SUNDAY AFTERNOON)
ISSUED AT 1234 PM EST SAT JAN 3 2015

THE REGION WAS BLANKETED BY IFR OR LIFR CONDITIONS EARLY THIS
AFTERNOON. LITTLE CHANGE IS EXPECTED AS RAIN...AND SOME FREEZING
RAIN AT LAN AND JXN...CONTINUES. TEMPS WILL CONTINUE TO WARM AND
ANY FREEZING RAIN AT THE TAFS SITES SHOULD WIND DOWN YET THIS
AFTERNOON. WINDS WILL CONTINUE TO DIMINISH...SO THIS SHOULD ALLOW
THE FOG TO BECOME DENSER WITH TIME ALONG WITH CEILINGS LOWERING.
WIDESPREAD LIFR CAN BE EXPECTED BY LATE AFTERNOON AND THIS SHOULD
LINGER PAST MIDNIGHT.

AS THE SYSTEM PASSES THROUGH MORE WIND AND COLDER AIR ARRIVES
TOWARD DAYBREAK. THIS SHOULD HELP LIFT THE CEILING SOMEWHAT.
HOWEVER WITH THE COLDER AIR...THE RAIN WILL SWITCH TO SNOW AND
VSBYS SHOULD REMAIN IFR OR LIFR. THE STEADIEST SNOWS SHOULD BE
SEEN ACROSS THE I-96 TAF SITES. RUNWAYS COULD QUICKLY BECOME QUIET
ICY AND SNOW COVERED AS TEMPS ARE EXPECTED TO DROP FROM THE LOWER
30S AROUND DAYBREAK...INTO THE MID 20S BY NOON SUNDAY.

&&

.MARINE...
ISSUED AT 312 PM EST SAT JAN 3 2015

WINDS WILL INCREASE SUNDAY MORNING AND ARE LIKELY TO TOP OUT NEAR
GALE FORCE INTO SUNDAY NIGHT. THEREFORE I UPGRADED THE WATCH TO A WARNING.
THE WIND WILL DIMINISH SOMEWHAT BY MONDAY AS THE PRESSURE GRADIENT
WEAKENS. FREEZING SPRAY WILL BECOME AN INCREASING CONCERN SUNDAY
AFTERNOON INTO MONDAY AS WATER TEMPERATURES ARE GENERALLY IN THE
UPPER 30S...THE WIND WILL BE OVER 20 KNOTS AND THE AIR TEMPERATURE
WILL BE FALLING INTO THE TEENS.

&&

.HYDROLOGY...
ISSUED AT 312 PM EST SAT JAN 3 2015

THE POTENTIAL FOR FREEZE UP ICE JAMS ON THE RIVERS WILL CONTINUE
TO INCREASE INTO NEXT WEEK...WITH ACCELERATED ICE DEVELOPMENT
EXPECTED SUNDAY THROUGH THE REST OF NEXT WEEK. PATCHES OF ICE CAN
ALREADY BE SEEN FLOATING DOWN THE GRAND RIVER NEAR ROBINSON
TOWNSHIP. AVERAGE TEMPERATURES WILL PLUNGE WELL BELOW 20 DEGREES
NEXT WEEK WITH HIGHS ONLY IN THE TEENS. THERE IS POTENTIAL FOR
SIGNIFICANT LAKE EFFECT SNOW ACCUMULATIONS WITHIN TWO COUNTIES OF
THE LAKESHORE MONDAY NIGHT INTO TUESDAY.
