AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
1147 AM EST SUN DEC 21 2008

LATEST UPDATE...SYNOPSIS/SHORT TERM/AVIATION/HYDRO...

.SYNOPSIS...(1147 AM EST SUN DEC 21 2008)
LAKE EFFECT SNOW SQUALLS AND WINDS GUSTING TO 40 MPH WILL PRODUCE
NEAR BLIZZARD CONDITIONS TODAY AND TONIGHT. TEMPERATURES IN THE
SINGLE DIGITS AND TEENS WILL MAKE IT FEEL EVEN COLDER...WITH WIND
CHILLS DOWN TO 15 BELOW ZERO AT TIMES. CONDITIONS WILL IMPROVE BY
MONDAY BUT ANOTHER WINTER STORM IS EXPECTED FOR TUESDAY AND
WEDNESDAY. AT THIS POINT...CHRISTMAS DAY LOOKS QUIET WITH HIGH
PRESSURE BUILDING IN. ANOTHER STORM IS POSSIBLE NEXT WEEKEND.

&&

.SHORT TERM...(1147 AM EST SUN DEC 21 2008)
(THIS AFTERNOON THROUGH TUESDAY)
NO CHANGES TO HEADLINES. SNOW INTENSITY HAS DECREASED LAST FEW HOURS
AS EXTREMELY COLD AND DRY AIR IS NOW MOVING ACROSS THE LAKE. BLOWING
SNOW WILL CONTINUE TO BE A PROBLEM AS WINDS WILL BE GUSTING TO 35 TO
45 MPH. TWEAKED TEMPS BASED ON CURRENT OBS AND COLD AIR ADVECTION
CONTINUING THROUGH THE AFTERNOON. WIND CHILLS COULD BE DOWN NEAR 15
BELOW ZERO AT TIMES.

SOME ADJUSTMENTS TO THE HEADLINES WILL LIKELY BE MADE WITH THE
AFTERNOON ZONE ISSUANCE. WILL PROBABLY DOWNGRADE IONIA AND CALHOUN
COUNTIES AND POSSIBLY OTHERS TO WINTER WEATHER ADVISORIES AS FLOW
BECOMES NORTHWEST AND HEAVIER SNOW WILL BE CONFINED TO THE LAKE
MICHIGAN COASTAL AREA. BLOWING SNOW WILL STILL BE A PROBLEM THROUGH
THE EVENING. REST OF PREVIOUS DISCUSSION FOLLOWS.

AS THE TROUGH ON THE BACKSIDE OF THE SFC LOW DROPS THROUGH THE CWFA
LATE THIS AFTERNOON AND EVENING...THE FLOW SHOULD VEER TO THE NW AND
SHIFT THE BEST LAKE EFFECT TO THE SW CORNER OF THE CWFA AND THE FAR
NW CORNER. INLAND AREAS WILL SEE A BRIEF SHOT OF SNOW AS THE TROUGH
DROPS SOUTH THROUGH THE AREA. MODELS REALLY DIMINISH THE SFC
CONVERGENCE BY 12Z MON AFTER THE TROUGH PASSES SOUTH OF THE AREA.
ONLY LIGHT RESIDUAL LAKE EFFECT IS EXPECTED ON MON AS INVERSION
HEIGHTS WILL BE ON THERE WAY DOWN AND VERY LITTLE SFC CONVERGENCE IS
FOUND.

NEXT SYSTEM IS EXPECTED TO MOVE ACROSS THE AREA ON TUESDAY. THIS
SHOULD BRING A FEW INCHES OF SNOW TO THE AREA AS A RESULT OF A BURST
OF WAA/ISENTROPIC ASCENT. WINDS WILL BE MAINLY SOUTH AHEAD OF
IT...SO LAKE ENHANCEMENT WILL BE LIMITED IN AREA TO LITTLE AND BIG
SABLE POINTS.

&&

.LONG TERM...(446 AM EST SUN DEC 21 2008)
(TUESDAY NIGHT THROUGH SATURDAY)
OVERALL THERE SEEMS TO BE SOME RETROGRESSION GOING ON AT THE JET
STREAM LEVELS OVER NORTH AMERICA AND THIS WOULD IN TIME RESULT IN A
TRANSITION TO A TAMER WEATHER PATTERN FOR SOUTHWEST MICHIGAN IN
ABOUT A WEEK. WHAT I AM SAYING HERE IS THE LONGWAVE TROUGH... WHICH
NOW SEEMS TO BE NEAR THE GREAT LAKES... WILL BY THIS TIME NEXT WEEK
BE NEAR THE WEST COAST OF NORTH AMERICA. THAT WILL RESULT THE
PRIMARY STORM TRACK BEING MUCH FARTHER WEST AND NORTH OF OUR AREA IN
SOUTHWEST MICHIGAN.

BETWEEN THEN AND NOW WE HAVE SEVERAL BIG STORMS TO DEAL WITH. THE
FIRST WILL BE IN THE WEDNESDAY TIME FRAME. THE SECOND IS TOWARD THE
WEEKEND. THE TREND HERE IS EACH SYSTEM WILL TRACK FARTHER NORTH AND
WEST THEN THE PREVIOUS SYSTEM. WARMER SURFACE TEMPERATURES ARE SEEN
WITH TIME DUE TO THIS.

FOR THE WEDNESDAY STORM THERE IS THE HINT OF A MERGER WITH THE
NORTHERN AND SOUTHERN STREAM WITH THE SYSTEM. THIS WOULD HAPPEN IN
THE WEDNESDAY TIME FRAME. CURRENTLY THERE IS A FAIRLY STRONG SYSTEM
NEAR THE NORTH POLE THAT DIVES SOUTHEAST TO NEAR HUDSON BAY BY
WEDNESDAY. THAT HAPPENS AS YET ANOTHER STRONG PACIFIC STORM...COMING
IN FROM SOUTHERN BRITISH COLUMBIA MONDAY DIVES SOUTHEAST TOO INTO
SOUTHERN PLAINS BY TUESDAY. THAT RESULTS IN COUPLED JET NEAR THE
GREAT LAKES WHICH IN TURN CAUSES QUITE THE STORM TO DEVELOP AND
TRACK THROUGH THE CENTRAL GREAT LAKES. THE TREND IN THE ECMWF AND
GFS IS TOWARD A DEEPER STORM FARTHER WEST. THERE IS A 70 KNOT LOW
LEVEL INFLOW WITH GULF MOISTURE STREAMING NORTH TOWARD THE WARM
FRONT. IF ALL THIS HAPPENED WE WOULD SEE THE THREAT OF AN ICE STORM
AND SNOW STORM TO OUR CWA TUESDAY NIGHT INTO WEDNESDAY. SO I
INTRODUCED FREEZING RAIN AND SLEET TO THE SOUTHERN AND EASTERN CWA
WEDNESDAY.

THE MORE WRAPPED UP SYSTEM ON WEDNESDAY WOULD RESULT IN BETTER LAKE
EFFECT SNOWS WEDNESDAY NIGHT INTO THURSDAY. SO I INCREASED POPS NEAR
THE LAKE SHORE THURSDAY TO ACCOUNT FOR THIS TREND.

THE NEXT MAJOR SYSTEM TACKS EVEN FARTHER WEST THAN THE WEDNESDAY
SYSTEM DID. THIS GOES BACK TO MY RETROGRESSION IDEA. SINCE THE
SYSTEMS THAT CREATES THAT STORM IS NOW WELL WEST OF THE DATE LINE
THE MODELS ARE NOT DOING WELL WITH HOW THIS PLAYS OUT I DID NOT
CHANGE THE GRIDS MUCH. THE ECMWF DOES NOT AGREE WITH THE GFS ON
TIMING OR TRACK AND THE CONSISTENCY FROM RUN TO RUN FOR BOTH THE GFS
AND ECMWF ARE QUESTIONABLE AT BEST ANYWAY. THOUGH THE TREND FOR A
MORE WESTERN TROUGH SEEMS SOLID. WE COULD BE DEALING WITH A FAIR
AMOUNT OF RAIN WITH SURFACE TEMPS IN THE 40S OR 50S BY EARLY IN THE
COMING WEEKEND IF THE CURRENT TRENDS IN THE MODELS CONTINUES. WE
WILL HAVE TO WATCH HOW THIS PLAYS OUT... COULD BE HYDRO ISSUES NEXT
WEEKEND.

&&

.MARINE...(446 AM EST SUN DEC 21 2008)
NO CHANGES WILL BE MADE TO THE MARINE HEADLINES. GALES WILL BE
DEVELOPING OUT ON THE WATERS WITHIN THE NEXT FEW HOURS AS THE COLD
AIR RUSHES IN OVER THE AREA BEHIND THE COLD FRONT. THESE GALES ARE
EXPECTED TO REMAIN UP THROUGH MOST OF THE NIGHT TONIGHT. THE COLD
AIR AND AND STRONG WINDS ARE ALSO EXPECTED TO PRODUCE HEAVY FREEZING
SPRAY THROUGH TONIGHT. A BRIEF BREAK IN THE WINDS ARE EXPECTED ON
MONDAY AND MONDAY NIGHT BEFORE WINDS COME UP AGAIN ON TUESDAY AHEAD
OF THE NEXT SYSTEM.

&&

.AVIATION...(1147 AM EST SUN DEC 21 2008)
NEAR BLIZZARD CONDITIONS WILL CONTINUE THIS AFTERNOON AT THE MKG...
GRR AND AZO TAF SITES WITH LIFR TO VLIFR CONDITIONS. VERY COLD TEMPS
AND WESTERLY SUSTAINED WINDS OF AROUND 25 KTS WITH GUSTS OF 30 TO 40
KTS WILL RESULT IN QUARTER MILE OR LESS VISBYS IN BLOWING SNOW AT
THOSE SITES.

VISBYS MAINLY IN THE THREE QUARTERS TO TWO MILE RANGE AND IFR TO
LIFR CONDITIONS ARE ANTICIPATED AT THE LAN... BTL AND JXN SITES THIS
AFTERNOON WHERE THERE IS LESS SNOW ON THE GROUND AND SNOW SHOWERS
ARE LIGHTER.

CONDITIONS WILL GRADUALLY IMPROVE AT ALL TAF SITES OVERNIGHT AS WIND
SPEEDS FINALLY BEGIN TO DIMINISH (ESPECIALLY AFTER MIDNIGHT).
DIMINISHING WIND SPEEDS WILL ALSO RESULT IN LINGERING LAKE EFFECT
SNOW SHOWERS BECOMING MAINLY CONCENTRATED WEST OF US-131. IN FACT
CONDITIONS SHOULD IMPROVE INTO THE VFR FLIGHT CATEGORY AT ALL TAF
SITES MONDAY.

&&

.HYDROLOGY...(1147 AM EST SUN DEC 21 2008)
ICE JAMMING IS OCCURRING ON THE MUSKEGON RIVER IN OSCEOLA COUNTY AND
ALSO ON THE PERE MARQUETTE RIVER AT SCOTTVILLE...AND THE FLAT RIVER
AT SMYRNA. RIVER FORECAST STATEMENT HAS BEEN ISSUED FOR SMYRNA AND
SCOTTVILLE AND THE OSCEOLA COUNTY ICE JAM IS BEING MONITORED.

THERE IS A POTENTIAL OF SOME RAINFALL AND WARMER TEMPERATURES LATER
THIS WEEK WITH ADDITIONAL STORMS SYSTEMS MOVING IN. THIS WILL HAVE
TO BE WATCHED WITH PLENTY OF WATER LOCKED UP IN THE SOLID SNOWPACK
IN PLACE ACROSS MOST OF THE CWFA.

&&

.GRR WATCHES/WARNINGS/ADVISORIES...
LM...GALE WARNING AND HEAVY FREEZING SPRAY WARNING FROM ST. JOSEPH
TO MANISTEE LATE TONIGHT THROUGH MONDAY MORNING.
MI...WINTER STORM WARNING FOR WESTERN FORECAST AREA AND WINTER
WEATHER ADVISORY FOR EASTERN COUNTIES THROUGH 10 AM MONDAY.
