AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
1243 PM EST FRI JAN 14 2011

LATEST UPDATE...AVIATION...

.SYNOPSIS...(354 AM EST FRI JAN 14 2011)
ONE CLIPPER IS MOVING OUT OF THE AREA AND ANOTHER WILL MOVE ACROSS
NORTHERN LOWER MICHIGAN EARLY SATURDAY. LIGHT SNOW SHOWERS WILL
CONTINUE ALONG THE LAKE SHORE THIS MORNING. INLAND A MIX OF FLURRIES
AND LIGHT SNOW SHOWERS ARE EXPECTED TODAY BUT LITTLE IN THE WAY OF
ADDITIONAL ACCUMULATIONS. ACCUMULATING SNOW IS EXPECTED TONIGHT AND
SATURDAY MORNING ESPECIALLY NORTH OF I-96. HIGHS IN THE MID 20S ARE
EXPECTED FOR THE NEXT FEW DAYS...ALTHOUGH CLOSER TO 20 ON SUNDAY.

&&

.SHORT TERM...(1156 AM EST FRI JAN 14 2011)
(TONIGHT THROUGH SUNDAY)
FORECAST CONCERNS DEAL WITH THE CURRENT HEADLINE AND SNOW POTENTIAL
TONIGHT.

DECIDED TO CANCEL THE CURRENT ADVISORY.  AS EXPECTED THE SNOWFALL
HAS BEEN DECREASING IN INTENSITY.  ANY ADDITIONAL ACCUMULATION
THROUGH THIS AFTERNOON TO REMAIN UNDER AN INCH. IN ADDITION HIGHWAY
SPEEDS ARE CLOSE TO NORMAL ALONG 31 NORTH OF GRAND HAVEN SO NO MUCH
IMPACT FROM THE CURRENT SNOWFALL.

TONIGHT...THE FAST MOVING STORM MOVES IN.  TOUGH CALL ON HOW MUCH
IMPACT THE LAKE MOISTURE ENHANCES THE SYSTEM.  FROM 03Z TO 09Z
STRONGER LOW LEVEL CONVERGENCE IS SEEN FROM NEAR MUSKEGON TO
LUDINGTON FROM THE 12Z NAM.  MOISTURE HEIGHTS DEEPEN CONSIDERABLY
WITH DEEPER OMEGA SEEN.  IT APPEARS THAT SNOWFALL RATES WILL LIKELY
REACH AN INCH PER HOUR FOR A COUPLE HOURS AT LEAST.  I DO ENVISION
ISSUING SOME HEADLINES FOR THIS EVENT AT THE 3 TO 4 PM FORECAST
ISSUANCE.  ALSO A WEBINAR WILL BE CONDUCTED.  DRY AIR AROUND 700 MB
SURGES IN BETWEEN 12Z AND 15Z.  THIS SHOULD CUT OFF THE WIDESPREAD
ACCUMULATING SNOW.

&&

.LONG TERM...(354 AM EST FRI JAN 14 2011)
(SUNDAY NIGHT THROUGH THURSDAY)
BASED ON THE LATEST GUIDANCE I SEE LITTLE QUESTION WINTER LIKE
WEATHER WILL CONTINUE THROUGH THIS COMING WEEK. THE SYSTEM ON
TUESDAY CONTINUES TO LOOK BETTER AND BETTER AS THERE HAS BEEN MORE
CONSISTENCY IN THAT THE SYSTEM WILL BE THERE AND IT WILL BE FAR
ENOUGH NORTH TO BRING US A SIGNIFICANT PRECIPITATION EVENT. WHEN WE
ARE NOT UNDER THE INFLUENCE OF A SYNOPTIC SCALE STORM SYSTEM...
WINDS WILL BE FROM A VARIATION OF A WESTERLY DIRECTION (NO HIGH OVER
CENTRAL CANADA PASSING JUST NORTH OF US TO BRING EASTERLY WINDS) SO
LAKE EFFECT WILL BE ON GOING THROUGH THE WEEK WHEN THERE IS NOT
SYNOPTIC SNOWFALL OCCURRING. THEN COMES THE ISSUE OF THAT AIR MASS
FROM THE SIBERIAN ARCTIC. I STILL BELIEVE THAT WILL BRING US THE
COLDEST WEATHER OF THE WINTER BUT THE QUESTION NOW IS WHEN? MY
CONFIDENCE IN THE GENERAL OUT COME OF THIS FORECAST IS HIGH BUT MY
CONFIDENCE IN THE DETAILS IS RATHER LOW SINCE THE PATTERN IS SO
ANOMALOUS.

ON THE HEMISPHERIC SCALE... OUR MAIN ISSUE CONTINUES TO BE A
COMBINATION OF THE HIGH LATITUDE BLOCKING NORTHWEST OF ALASKA
THANK TO THAT ANOMALOUSLY STRONG UPPER HIGH (3-4 STANDARD DEVIATIONS
FROM NORMAL)AND THE EAST ASIAN JET CROSSING THE PACIFIC NEAR 35N
WITH WINDS UP TO 210 KNOTS IN THE CORE OF THE JET (JUST EAST OF
JAPAN ON SUNDAY).  ONE THING THE ECMWF DOES THAT I AM NOT TO WARM
AND FUSSY WITH IS IT SEEMS TO WANT TO BREAK DOWN THE WESTERN RIDGE
WAY TO QUICKLY COMPARED THE GFS. ON THE OTHER HAND THERE IS THAT 210
KNOT JET CORE WEST OF THE DATELINE BY MONDAY EVENING.  THAT IS WHY
THE ECMWF DOES NOT BRING DOWN AS COLD OF AIR LATE IN THE WEEK AS THE
GFS DOES. THE LOW LEVEL THICKNESS FIELDS (1000/925 MB ) SO EVEN
THROUGH THE ECMWF DOES NOT BRING THE CORE OF THE COLDEST AIR INTO
LOWER MICHIGAN THIS COMING WEEK IT DOES BRING AIR COLD ENOUGH TO
GIVE SW LOWER MICHIGAN HIGHS IN THE TEENS IN PLACE THE SECOND HALF
OF NEXT WEEK. IN FACT ON THURSDAY AND FRIDAY IT SHOWS THE COLDEST
AIR GOING SOUTH OF MI THROUGH NORTHERN INDIANA. THE 1000/925 MB
THICKNESS FROM THE ECMWF WOULD BRING HIGHS IN THE SINGLE DIGITS TO
AREA SOUTH OF INTERSTATE 94 THURSDAY AND MAYBE FRIDAY. FOR NOW I DID
NOT CHANGE OUR FORECAST GRIDDED TEMPS TO MUCH IT WILL BE COLDER THAN
NORMAL WED THROUGH FRIDAY.

AS FOR OUR STORM ON TUESDAY... BOTH THE GFS AND ECMWF PLAY THE MAIN
SURFACE LOW WITH THE NORTHERN STREAM JET CORE. I HAVE AN ISSUE WITH
BOTH OF THOSE SOLUTIONS. THE STRONGEST WINDS ON BOTH MODELS ARE
SOUTH OF KENTUCKY. I HAVE TO WONDER IF WE WOULD SEE A COLD FRONT
OCCLUSION GO BY US TUESDAY WITH THE PRIMARY SYSTEM IN EFFECT WOULD
STAY SOUTH. THAT WOULD KEEP THE PRECIPITATION ALL SNOW HERE TUESDAY
AS WE WOULD BE IN THE OCCLUSION LIFT ZONE OF THE SYSTEM. EITHER WAY
850 MB TEMPS NEAR 20 BELOW ZERO FOLLOW THE SYSTEM AND THAT WILL
SURELY GENERATE LAKE EFFECT SNOW SO I INCREASE THE POP NEAR THE LAKE
SHORE FOR WEDNESDAY TO SHOW THAT IMPACT.

THERE IS ANOTHER NORTHERN STREAM WAVE SHOWN ON BOTH THE ECMWF AND
GFS THAT COMES THROUGH THE AREA IN THE THURSDAY/FRIDAY TIME FRAME.
THAT WOULD ONLY BRING MORE SNOW. SURFACE TEMPS WOULD DEPEND ON IF
THE SYSTEM GOES SOUTH OR NORTH HERE.

&&

.AVIATION...(1243 PM EST FRI JAN 14 2011)
LAKE EFFECT SNOW SHOWERS CONTINUE TO DECREASE IN INTENSITY AND
COVERAGE EARLY THIS AFTERNOON.  THIS TREND IS EXPECTED TO CONTINUE
AND THE TAF SITES WILL TREND UPWARD TO MVFR OR VFR.

ANOTHER ROUND OF SNOW IS EXPECTED AS ANOTHER CLIPPER SYSTEM COMES
ACROSS THE GREAT LAKES TONIGHT.  A BURST OF SNOW IS EXPECTED WITH
THIS SYSTEM...ARRIVING OVER THE WESTERN TAF SITE...MKG...AROUND 03Z
AND SPREADING EAST THROUGH THE WEE HOURS OF SATURDAY MORNING.  IFR
OR LIFR VSBYS ARE EXPECTED AS THE SNOW COULD BE HEAVY AT TIMES.
THIS DOES APPEARS TO BE A RELATIVELY SHORT BURST OF SNOW AND SHOULD
ALREADY BE EXITING THE EASTERN TAF SITES...LAN/JXN AROUND 12-13Z.
ONCE THE SNOWS END THERE SHOULD BE A RAPID IMPROVEMENT IN THE VSBYS
AS ANY LAKE EFFECT SNOW SHOWERS BEHIND THE SYSTEM ON SATURDAY
MORNING SHOULD BE LIGHT AND SCATTERED.

&&

.MARINE...(1156 AM EST FRI JAN 14 2011)
WINDS WILL INCREASE TONIGHT AHEAD OF THE NEXT CLIPPER. A SCA WILL
PROBABLY BE NEEDED FOR LATE TONIGHT AND SATURDAY.

&&

.HYDROLOGY...(354 AM EST FRI JAN 14 2011)
NO MAJOR ICE JAMS YET...BUT SOME FLUCTUATIONS WERE NOTED ON AREA
RIVERS. WE PROBABLY WON/T SEE MUCH MORE ICE BUILDUP FOR THE NEXT FEW
DAYS AS AVERAGE TEMPS WILL BE JUST ABOVE 20.

&&

.GRR WATCHES/WARNINGS/ADVISORIES...
MI...NONE.
LM...NONE.

A MORE SIGNIFICANT SNOW EVENT WILL BEGIN EARLY TONIGHT AS ANOTHER
CLIPPER SYSTEM HEADS FOR THE NORTHERN GREAT LAKES. A NEW LAKE

ICE WILL CONTINUE TO DEVELOP ON AREA RIVERS. WATER LEVELS MAY
FLUCTUATE IN AREAS PRONE TO ICE JAMS.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

THE CLIPPER SYSTEM CROSSING THE NORTHERN GREAT LAKES SATURDAY
MORNING WILL BRING 2 TO 4 INCHES OF SNOW TO THE LAKE SHORE AREAS
OF SOUTHWEST LOWER MICHIGAN.   HIGHER AMOUNTS ARE POSSIBLE NORTH
MUSKEGON. ELSEWHERE EXPECT 1 TO 3 INCHES...MOSTLY

ACCUMULATING SNOW IS POSSIBLE FOR THE AREA MONDAY NIGHT INTO TUESDAY
AS A SYSTEM MOVES TOWARD MICHIGAN FROM THE SOUTHERN PLAINS WHILE
ARCTIC AIR OVER SOUTHERN CANADA WILL BE POISED TO BE PULLED IN
BEHIND THE STORM.

TEMPERATURES WILL BE MARGINAL FOR INCREASED RIVER ICE THIS WEEKEND
BUT WITH THE ARRIVAL OF AN ARCTIC AIR-MASS EARLY NEXT WEEK A MORE
SIGNIFICANT INCREASE IN RIVER ICE IS EXPECTED. THIS WILL LEAD TO
FLUCTUATING LEVELS IN AREAS PRONE TO ICE JAMS.
