AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
1215 PM EST WED FEB 18 2009

LATEST UPDATE...AVIATION...

.SYNOPSIS...(258 AM EST WED FEB 18 2009)
LOW PRESSURE WILL MOVE ACROSS SOUTHERN LOWER MICHIGAN TODAY BRINGING
SOME SNOW AND RAIN. AFTER THE LOW MOVES BY...COLD AIR WILL RETURN
WITH STRONG WINDS AND LAKE EFFECT SNOW SHOWERS. THE COLD AIR WILL
LAST RIGHT THROUGH THE WEEKEND WITH A WINTER STORM POSSIBLE FOR
SATURDAY.

&&

.SHORT TERM...(1100 AM EST WED FEB 18 2009)
(TODAY THROUGH FRIDAY)
FORECAST APPEARS TO BE ON TRACK THIS MORNING.  LOW PRESSURE WAS OVER
NRN INDIANA AS OF 15Z.  LIGHT SNOW WAS OCCURRING ACROSS THE NORTHERN
CWA...WITH LIGHT RAIN ACROSS THE CENTRAL AND SOUTHERN PORTIONS.  AS
THE LOW PASSES WINDS WILL SHIFT AROUND TO THE NW EARLY THIS
AFTERNOON AND COOLER AIR WILL FILTER INTO THE AREA.  WE WILL BEGIN
TO SEE A CHANGE OVER TO SNOW ACROSS THE I96 CORRIDOR SHORTLY AFTER
NOON...AND THE I94 CORRIDOR BY MID TO LATE AFTERNOON.  HAVE TAKEN
OUT THE MENTION OF ANY SNOW ACCUM SOUTH OF I96 AS ANY SNOW THAT
FALLS HERE WILL BE SLUSHY WET FLAKES THAT SHOULD RESULT IN LITTLE
TO NO ACCUMULATION DURING THE DAY TIME HOURS.  1-2 INCHES STILL LOOK
FINE ACROSS THE NORTH AND LESS THAN AN INCH ACROSS THE CENTRAL CWA
TODAY.  HEADLINES...MAINLY WEST OF U.S. 131...KICK IN AFTER 4 PM AS
THE COLDER AIR FILTERS IN AND THE LAKE EFFECT AND WINDS INCREASE.
BY THE END OF THE DAY WINDS SHOULD BE GUSTING TO 35 MPH ALONG THE
LAKESHORE...AND AROUND 25 MPH INLAND.

THEN THINGS GET INTERESTING AS WINDS WILL BE GUSTING OVER 35 MPH AND
LAKE EFFECT SNOW SHOWERS WILL BE ACCUMULATING ENOUGH SNOW TO CAUSE
SOME BLOWING AND DRIFTING. EXPECT A GENERAL 3 TO 6 INCHES IN THE
ADVISORY AREA WITH LESSER AMOUNTS FURTHER INLAND IN THIS NORTHWEST
FLOW EVENT.

SNOW SHOWERS WILL CONTINUE INTO THURSDAY NIGHT THEN DIMINISH ON
FRIDAY AS SFC RIDGING BUILDS IN AND INVERSION HEIGHTS LOWER.

&&

.LONG TERM...(258 AM EST WED FEB 18 2009)
(FRIDAY NIGHT THROUGH TUESDAY)
THE MAIN CONCERN IN THE LONG TERM DEALS WITH THE POTENTIAL STORM FOR
FRIDAY NIGHT INTO SATURDAY.  THE NAM TAKES THIS SYSTEM MUCH FURTHER
SOUTH THAN THE GFS OR ECMWF...SUGGESTING DRY WEATHER.  CONSIDERING
THE GOOD AGREEMENT FROM THE GFS AND ECMWF...WILL FAVOR THEIR
SOLUTIONS AND BUMP UP THE POPS TO LIKELY FOR SOUTHERN LOCATIONS AND
I ADDED SOME ACCUMULATION.  AT 00Z SAT NOT MUCH IN THE WAY OF SNOW
WILL BE AROUND...HOWEVER IT APPEARS THAT BY 12Z SAT THE SNOW WILL
HAVE SPREAD IN.  THIS QUICK MOVING SYSTEM WILL BE OUT OF HERE BY 00Z
SUN...BUT LAKE EFFECT BEHIND IT MAY KEEP THE SNOW GOING NEAR THE
LAKESHORE.  WE MAY EVENTUALLY NEED SOME WINTER WEATHER HEADLINES FOR
THIS POTENTIAL STORM. I WILL ADD SOME WORDING IN THE HWO CONCERNING
THIS SYSTEM. WITH A NORTHWESTERLY FLOW BEHIND THE DEPARTING SYSTEM
UNSEASONABLY COLD WEATHER WILL PREVAIL THIS WEEKEND.

&&

.AVIATION...(1215 PM EST WED FEB 18 2009)
IFR TO LIFR CONDITIONS WILL CONTINUE THROUGH THE REST OF THE
AFTERNOON DUE TO LOW CIGS AND VISBYS MAINLY IN THE 1 TO 2 MILE
RANGE. LINGERING RAIN SHOWERS THROUGH EARLY TO MID AFTN WILL BECOME
MIXED WITH THEN QUICKLY CHANGE OVER TO SNOW SHOWERS AS WINDS VEER TO
THE WNW AND INCREASE LATE THIS AFTN.

WNW TO NW WIND GUSTS IN THE 25 TO 30 KT RANGE ARE ANTICIPATED
TONIGHT THROUGH 18Z THURSDAY AT ALL TAF SITES. LAKE EFFECT SNOW
SHOWERS WILL ALSO DEVELOP OVERNIGHT THROUGH 18Z THURSDAY... AND
SHOULD BE MOST PROMINENT NEAR AND WEST OF US-131. THESE TYPE OF
GUSTS WILL ALSO RESULT IN BLOWING SNOW.

A WIDE RANGE OF CONDITIONS RANGING FROM MAINLY MVFR AT OUR EASTERN
TAF SITES TO IFR TO LIFR CONDITIONS AT OUR WESTERN TAF SITES IS
ANTICIPATED TONIGHT THROUGH 18Z THURSDAY DUE TO SNOW SHOWERS AND
BLOWING SNOW. THE MKG AND AZO TAF SITES WILL INCUR THE GREATEST
IMPACTS FROM SNOW AND BLOWING SNOW IN THAT TIME FRAME.

&&

.HYDROLOGY...(1100 AM EST WED FEB 18 2009)
FLOOD WARNING FOR ROBINSON TOWNSHIP WAS CANCELED THIS MORNING AS THE
RIVER WAS REPORTED TO BE BACK WITHIN ITS BANKS. SOME LIGHT  LIQUID
QPF TODAY SHOULD NOT AFFECT RIVER LEVELS. COLD WEATHER TONIGHT
THROUGH THE WEEKEND MAY RESULT IN SOME ICE BUILD UP ON RIVERS BY
NEXT WEEK.

&&

.GRR WATCHES/WARNINGS/ADVISORIES...
WINTER WEATHER ADVISORY IN EFFECT FROM 4 PM WEDNESDAY TO 7 PM
EST THURSDAY FOR MASON...LAKE...OCEANA...NEWAYGO...MUSKEGON...
