AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
1235 PM EST THU FEB 3 2011

LATEST UPDATE...AVIATION...

.SYNOPSIS...(354 AM EST THU FEB 3 2011)
THE WEATHER IS EXPECTED TO REMAIN RELATIVELY QUIET AND COOL THROUGH
THE END OF THE WEEK...AND EVEN INTO THE WEEKEND. A COUPLE OF WEAKER
SYSTEMS WILL MOVE THROUGH THE AREA OVER THE WEEKEND. THESE SYSTEMS
ARE NOT EXPECTED TO PRODUCE MUCH...IF ANY SNOWFALL ACROSS THE AREA.

&&

.SHORT TERM...(354 AM EST THU FEB 3 2011)
(TODAY THROUGH SATURDAY)
MAIN ITEMS OF CONCERN WITH THIS FCST PACKAGE ARE BLOWING SNOW FOR
TODAY...AND THE POTENTIAL OF SNOW ACROSS THE AREA THROUGH SATURDAY
AS A FEW WEAK WAVES OF LOW PRESSURE MOVE THROUGH.

WINDS ARE EXPECTED TO PICK UP A BIT TODAY AFTER A BREAK IN THE WINDS
THIS MORNING. THIS OCCURS AS A SYSTEM MOVING ACROSS ONTARIO WILL
TIGHTEN THE PRESSURE GRADIENT ACROSS THE AREA AS IT SQUEEZES AGAINST
THE 1040+ MB HIGH ACROSS THE SRN PLAINS THIS MORNING. THIS WIND WILL
LOWER THE WIND CHILLS A BIT ACROSS THE EAST BEFORE TEMPS WARM A BIT.
ALSO...THE WINDS ARE EXPECTED TO TAKE SOME OF THE FRESH SNOW FROM
TUE NIGHT/WED AND BLOW IT AROUND A BIT. WE DO NOT EXPECT THIS TO BE
SIGNIFICANT ENOUGH RIGHT NOW TO WARRANT AN ADVISORY...HOWEVER THIS
WILL NEED TO BE MONITORED BY THE DAY SHIFT. OTHERWISE STRONG
INVERSION HEIGHTS AROUND 2-3K FT AND DRY AIR WILL CAP ANY LAKE
EFFECT THAT TRIES TO GET GOING AND PROVIDE MOSTLY SUNNY SKIES.

A COUPLE OF PIECES OF UPPER ENERGY WILL THEN TRY AND APPROACH THE
AREA LATE FRI AND FRI NIGHT. ONE WILL BE DIVING SE OUT OF
CANADA...AND THE OTHER WILL BE LIFTING ENE OUT FROM THE TX
PANHANDLE. THE NRN ENERGY WILL APPROACH FIRST...AND WILL HAVE VERY
LIMITED MOISTURE DEPTH AVAILABLE. THE SRN STREAM WILL THEN APPROACH
THE AREA...ONLY TO GET SHUNTED SE OF THE AREA BY THE NRN STREAM
WAVE. MODELS GENERALLY ALL AGREE THAT THE SRN STREAM PCPN WILL MISS
THE AREA WHILE THE NRN STREAM WILL ONLY BRING A SMALL CHC TO THE
NORTH WHERE A LITTLE BETTER MOISTURE WILL BE FOUND.

ANOTHER WAVE WILL THEN APPROACH THE AREA ON SATURDAY. THIS WAVE IS
EXPECTED TO HAVE SLIGHTLY BETTER MOISTURE ASSOCIATED WITH
IT...ALTHOUGH IT WILL STILL BE LACKING DECENT MOISTURE FOR
WIDESPREAD PCPN. THE BEST CHC FOR SOME LIGHT SNOW WILL BE ACROSS THE
NRN PORTION OF THE CWFA WHERE THE MOISTURE WILL BE A BIT DEEPER.
THIS IS STILL A LOW CHC OF SNOW...SO WE WILL KEEP THE LOW CHC OF
SNOW IN THE FCST.

&&

.LONG TERM ...(354 AM EST THU FEB 3 2011)
(SATURDAY NIGHT THROUGH WEDNESDAY)
NO SIGNIFICANT CHANGES TO GOING FORECAST. LOOKS LIKE THE MAIN
WEATHER MAKER WILL BE A SFC WAVE DEVELOPING ON THE ARCTIC FRONT LATE
SUNDAY INTO EARLY MONDAY. THIS SHOULD BRING SOME SYNOPTIC SNOWS TO
MUCH OF THE FORECAST AREA....FOLLOWED BY SOME LAKE EFFECT SNOW
SHOWERS IN NORTHERLY FLOW INTO MONDAY NIGHT. ANOTHER CLIPPER ARRIVES
LATE WEDNESDAY WITH A REINFORCING SHOT OF EVEN COLDER ARCTIC AIR TO
FOLLOW.

&&

.AVIATION...(1235 PM EST THU FEB 3 2011)
THE MAIN CHALLENGE FOR AVIATORS TODAY WILL BE WIND GUSTS. SOME GUSTS
IN THE 25-30KT RANGE ARE POSSIBLE ESPECIALLY AT MKG AND GRAND
RAPIDS. SKIES WILL BE MAINLY CLEAR BUT THIS WILL ALLOW SOME MIXING
OF THESE HIGHER WINDS AT THE 1000-1500 FT LEVEL. THE WINDS NEVER
TOTALLY BACK DOWN OVERNIGHT...SO WILL REMOVE THE GUST MENTION AT ALL
BUT MKG WHERE A PERSISTENT WSW FLOW OFF LAKE MICHIGAN WILL LIKELY
KEEP GUSTS GOING.

OF SOME CONCERN IS ANY LOOSE SNOW BEING WHIPPED BY THE WIND AND
CREATING BLSN. THIS MAY CREATE LOCAL REDUCTIONS IN VISIBILITY BUT
TOUGH TO NAIL DOWN AT ANY ONE TIME WHEN THAT MAY OCCUR. WILL MONITOR
THE TRENDS THIS AFTERNOON AND ADD TEMPO OR PREDOMINANT CONDITIONS AS
WARRANTED.

&&

.MARINE...(354 AM EST THU FEB 3 2011)
WE WILL MAINTAIN THE SMALL CRAFT ADVISORY FOR THE ENTIRE NEARSHORE.
WINDS WILL PICK UP SOME THIS AFTERNOON AS TIGHTER PRESSURE GRADIENT
DROPS DOWN ACROSS THE AREA. WE ARE EXPECTING WINDS TO REMAIN IN THE
ADVISORY RANGE...WITH THE STRONGER WINDS ABOVE AN INVERSION ABOVE.
WINDS WILL REMAIN UP THROUGH AT LEAST FRIDAY.

&&

.HYDROLOGY...(335 PM EST WED FEB 02 2011)
LOTS OF SMALL VARIATIONS ON AREA RIVERS WERE NOTED ON WEDNESDAY.
MOST WERE DECLINING. HOWEVER THE FLAT RIVER AT SMYRNA JUMPED A FOOT
YESTERDAY BUT IS NOW DECREASING SLOWLY. NOT REALLY SURPRISED AT THE
FLUCTUATIONS GIVEN THE PROPENSITY FOR THIS STORM TO HAVE DEVELOPED
FRAZIL ICE. WE/LL CONTINUE TO MONITOR FOR POTENTIAL ICE JAMS.

&&

.GRR WATCHES/WARNINGS/ADVISORIES...
MI...NONE.
LM...SMALL CRAFT ADVISORY IN EFFECT FOR THE ENTIRE NEARSHORE.
