AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
1208 AM EST MON DEC 3 2012

.SYNOPSIS...
ISSUED AT 335 PM EST SUN DEC 2 2012

HIGH PRESSURE WILL SETTLE OVER THE REGION TONIGHT AND SUPPORT THE
DEVELOPMENT OF AREAS OF DENSE FOG. HIGH TEMPERATURES AT LEAST 20
DEGREES ABOVE NORMAL ARE EXPECTED ON MONDAY AS SOUTHERLY WINDS
INCREASE AHEAD OF A STRONG LOW PRESSURE SYSTEM IN SOUTH CENTRAL
CANADA. A COLD FRONT EXTENDING SOUTH FROM THAT SYSTEM WILL BRING
MORE RAIN AND SCATTERED THUNDERSTORMS MONDAY AFTERNOON AND NIGHT.
TEMPERATURES WILL COOL DOWN BEHIND THE COLD FRONT... BUT STILL
REMAIN ABOVE NORMAL THROUGH THE REST OF THE WEEK.

&&

.UPDATE...
ISSUED AT 902 PM EST SUN DEC 2 2012

ISSUES A DENSE FOG ADVISORY OVERNIGHT. IR LOOP SHOWS STRATOCU
RETREATING NWD ACROSS THE CENTRAL CWA ATTM. WE/LL LIKELY SEE VSBYS
OVER THE NRN CWA BEGIN TO FALL AS CLOUDS SCATTER OUT. ABUNDANT LOW
LEVEL MOISTURE COUPLED WITH LIGHT WINDS WILL ALLOW TEMPS TO FALL
TO NEAR THE DEWPOINT TONIGHT RESULTING IN AREAS OF DENSE FOG.

&&

.SHORT TERM...(THIS EVENING THROUGH TUESDAY NIGHT)
ISSUED AT 335 PM EST SUN DEC 2 2012

DENSE FOG IS THE MAIN CONCERN FOR LATER TONIGHT AS SFC HIGH PRESSURE
SETTLES OVERHEAD. THE COMBINATION OF LIGHT WINDS... WET GROUND FROM
RECENT RAIN... AND SFC DEW PTS IN THE MID 40S SHOULD CONTRIBUTE TO
EXTENSIVE STRATUS AND FOG FORMATION. THE FOG COULD BECOME DENSE AND
IMPACT THE MONDAY MORNING COMMUTE. NUMEROUS DENSE FOG ADVISORIES
WERE NEEDED EARLY SUNDAY MORNING UNDER THE SFC HIGH IN MN/IA.

THE FRONTAL BOUNDARY WHICH BROUGHT LAST NIGHT/S RAIN IS STILL SLOWLY
CROSSING THE REGION AND WILL STALL OUT IN A WEST TO EAST FASHION
NEAR THE MI/IN BORDER TONIGHT. THE FRONT WILL THEN LIFT BACK NORTH
AS A WARM FRONT ON MONDAY. WEAK SURFACE CONVERGENCE ALONG THE
BOUNDARY MAY PRODUCE AREAS OF DRIZZLE LATE TONIGHT AND MONDAY
MORNING BEFORE A SHOWER THREAT DEVELOPS IN THE AFTERNOON AHEAD OF
THE NEXT APPROACHING COLD FRONT.

HAVE DECIDED TO ADD A RISK OF THUNDER MONDAY AFTERNOON TO WRN AND
NRN SECTIONS OF THE CWFA WHERE STRONG THETA E ADVECTION SETS UP
AFTER 18Z AS THE LOW LEVEL JET INCREASES TO 40-50 KTS. MU CAPES ON
THE 12Z NAM ARE PROGGED TO BE AROUND 1000 J/KG IN THE AFTERNOON WEST
OF HIGHWAY 131... WHICH IS PRETTY IMPRESSIVE FOR DECEMBER.

WILL CARRY LIKELY POPS MONDAY NIGHT WITH THE COLD FRONTAL PASSAGE AS
MODELS HAVE BEEN CONSISTENTLY SHOWING WIDESPREAD QPF OF AROUND 0.25
INCH. MU CAPES ARE PROGGED TO DECREASE THROUGH THE NIGHT... BUT A
FEW HUNDRED JOULES SUPPORTS KEEPING A CHANCE OF THUNDER AS THE FRONT
COMES THROUGH.

WE HAVE A GOOD SHOT AT SOME SUNSHINE ON TUESDAY AS THE DRY SLOT
SWEEPS IN BEHIND THE DEPARTING COLD FRONT. ARRIVAL OF COLDER AIR
WITH H8 TEMPS OF -5 TO -10C TUESDAY NIGHT MAY SUPPORT A FEW LIGHT
SNOW SHOWERS WEST OF HWY 131.

.LONG TERM...(WEDNESDAY THROUGH SUNDAY)
ISSUED AT 335 PM EST SUN DEC 2 2012

TRANQUIL WX WITH SEASONABLY MILD TEMPS IS ANTICIPATED WEDNESDAY AS A
SFC HIGH PRESSURE RIDGE BUILDS IN. A COLD FRONT WILL BRING POTENTIAL
FOR SOME SHOWERS THURSDAY AND POSSIBLY SOME MIXED LIGHT RAIN/LIGHT
SNOW SHOWERS THURSDAY NIGHT AND FRIDAY.

A LOW PRESSURE WAVE WILL LIKELY DEVELOP AND TRACK NE ALONG THAT
BOUNDARY THIS WEEKEND BUT PCPN WITH THAT SYSTEM WILL MOST LIKELY
STAY SE OF OUR FCST AREA ALTHOUGH SOME LIGHTER PCPN MAY CLIP OUR
AREA SUNDAY. SEASONABLE TEMPS ARE ANTICIPATED THIS WEEKEND INTO
EARLY NEXT WEEK.

&&

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z MONDAY NIGHT)
ISSUED AT 1206 AM EST MON DEC 3 2012

NOT MUCH CHANGE TO THE FORECAST. DENSE FOG WILL PERSIST OVERNIGHT.
IFR/LIFR CONDITIONS EXPECTED AND SLOWLY LIFT DURING THE MID
MORNING HOURS. SHOWERS AND PERHAPS TSRA EXPECTED MONDAY EVENING AS
A COLD FRONT APPROACHES.

&&

.MARINE...
ISSUED AT 335 PM EST SUN DEC 2 2012

MAIN CONCERN FOR MARINERS WILL BE AREAS OF DENSE FOG TONIGHT INTO
MONDAY MORNING. THEN... INCREASING SOUTH WINDS WILL PROBABLY
NECESSITATE SMALL CRAFT ADVISORIES MONDAY AND MONDAY NIGHT.

&&

.HYDROLOGY...
ISSUED AT 335 PM EST SUN DEC 2 2012

RAINFALL AMOUNTS LAST NIGHT WERE QUITE VARIABLE... BUT GENERALLY
BETWEEN 0.25 AND 0.50 INCHES. A NARROW BAND OF HEAVIER RAIN IMPACTED
PARTS OF OCEANA AND NEWAYGO COUNTIES WHERE UP TO TWO INCHES MAY HAVE
FALLEN. THESE RAINS...AS WELL AS THE RAIN AMOUNTS OF 0.25 TO 0.50
EXPECTED WITH THE NEXT FRONT... WILL HAVE LITTLE IMPACT ON THE
ALREADY VERY LOW MAINSTEM RIVERS.

&&

.GRR WATCHES/WARNINGS/ADVISORIES...

     043>046-050>052-056>059-064>067-071>074.
