AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
1224 AM EDT SAT APR 16 2011

LATEST UPDATE...SHORT TERM...

.SYNOPSIS...(330 PM EDT FRI APR 15 2011)
A STRONG LOW PRESSURE SYSTEM WILL TRACK FROM NORTHERN MISSOURI TO
SAULT STE MARIE TONIGHT THROUGH SATURDAY NIGHT... THEN LINGER OVER
EASTERN ONTARIO ON SUNDAY BEFORE FINALLY DEPARTING SUNDAY NIGHT.

THIS SYSTEM WILL RESULT IN WINDY AND COOL CONDITIONS OVER THE
WEEKEND...ALONG WITH WIDESPREAD RAIN SHOWERS TONIGHT AND SATURDAY.
THE RAIN MAY MIX WITH OR CHANGE TO SNOW BEFORE ENDING SATURDAY
NIGHT... BUT LITTLE OR NO SNOW ACCUMULATION IS EXPECTED.

ANOTHER LOW PRESSURE SYSTEM WILL TAKE A SIMILAR PATH TUESDAY AND
TUESDAY NIGHT...RESULTING IN MORE WIDESPREAD RAIN FOR THE AREA.

&&

.SHORT TERM...(1224 AM EDT SAT APR 16 2011)
(TONIGHT THROUGH SUNDAY NIGHT)

ADDED SOME THUNDER TO THE GRIDS BASED ON LIGHTNING UPSTREAM. COLD
POOL WILL BEGIN TO MOVE INTO LOWER MICHIGAN OVERNIGHT STEEPENING
LAPSE RATES AND INCREASING INSTABILITY. NOT EXPECTING ANYTHING
ORGANIZED BUT WE COULD SEE A FEW LIGHTNING STRIKES ACROSS THE SRN
HALF OF THE CWA.

THE MAJORITY OF THE TOTAL RAIN AMOUNTS (NEAR ONE HALF INCH) SHOULD
OCCUR TONIGHT WITHIN THE WARM CONVEYOR BELT. THE RAIN ON SATURDAY
AND SATURDAY EVENING UNDERNEATH THE UPPER LOW WILL BE MORE
INTERMITTENT/SHOWERY IN NATURE... RESULTING IN LOWER AREAL QPF
AMOUNTS THAN TONIGHT.

THE POTENTIAL TO MIX WITH OR EVEN CHANGE TO SNOW SHOWERS STILL LOOKS
PRETTY GOOD SATURDAY EVENING PER ALL P-TYPE SCHEMES. LIMITING FACTOR
FOR ANY ACCUMULATIONS HOWEVER WILL BE BREVITY OF EVENT... LIMITED
QPF... AND WARM GROUND. THERE COULD BE UP TO AN INCH ON THE GRASS
ACROSS THE HIGHER ELEVATIONS AROUND TUSTIN.

SIGNIFICANT DRYING IS PROGGED AFTER 06Z SUN WHICH SHOULD END THE
PRECIP ALTOGETHER AND PERHAPS EVEN BRING IN A PARTIAL CLEARING TREND
LATE SATURDAY NIGHT INTO SUNDAY.

AS THE DEEP SFC LOW STALLS JUST NE OF THE SO... STRONG WINDS ARE
PROGGED WITHIN THE CYCLONIC/COLD ADVECTION PATTERN OVER LWR MI.
SUSTAINED WINDS OF 25-30 KTS ARE SHOWN IN THE GFS/MAV GUIDANCE...
AND SOUNDINGS SHOW DEEP MIXING TO 800 MB THAT COULD MIX DOWN SOME
GUSTS TO 45 KTS. THIS SEEMS REASONABLE SINCE MOISTURE PROFILES
SUGGEST WE/LL SEE SOME STRONG APRIL INSOLATION. THAT WOULD HELP
ACHIEVE THE DEEP MIXED LAYERS THAT ARE PROGGED... ESPECIALLY EAST OF
HWY 131.

MODELS HAVE SHIFTED THE SHOWERS ON SUNDAY NIGHT (RELATED TO MID
LEVEL FGEN ALONG THE BAROCLINIC ZONE) FARTHER SOUTH. HAVE THEREFORE
REMOVED POPS NORTH OF I-96 AND LOWERED POPS ALONG/SOUTH OF I-96.

&&

.LONG TERM...(330 PM EDT FRI APR 15 2011)
(MONDAY THROUGH FRIDAY)

A SLOW MOVING LOW PRESSURE SYSTEM WILL TRACK NORTHEAST FROM THE
SOUTHERN PLAINS STATES EARLY NEXT WEEK. THIS SYSTEM WILL BRING A
CHANCE OF RAIN MONDAY THROUGH TUESDAY NIGHT. WE WILL TWEAK POPS UP
SLIGHTLY TO LIKELY AND ALSO ADD MENTION OF A CHC OF TSTORMS TUESDAY
THROUGH TUESDAY NIGHT AS WEAK INSTABILITY DEVELOPS. LIGHT RAIN
SHOWERS
MAY LINGER INTO WEDNESDAY BEFORE ENDING. DRY WX WITH SEASONABLE
TEMPS WILL RETURN FOR LATE NEXT WEEK AS A SFC HIGH PRESSURE RIDGE
BUILDS IN.

&&

.AVIATION...(1205 AM EDT SAT APR 16 2011)
THE STRONG AND GUSTY WINDS WILL CONTINUE THROUGH MOST OF THE NIGHT
UNTIL THE FRONTAL SYSTEM GETS A LITTLE CLOSER TO THE TAF SITES
AROUND 12Z OR SO. AS THE FRONT COMES THROUGH DURING THE MID DAY
HOURS WINDS WILL NOT GUST MUCH MORE THAN 25 KNOTS BUT WHEN THE COLD
FRONT COMES THROUGH EXPECT GUSTS TO NEAR 40 KNOTS.

THE PRIMARY RAIN BAND WILL MOVE THROUGH THE CWA BTW 09Z AND 15Z. IT
WILL BE THAT RAIN BAND THAT WILL BRING THE IFR CIGS/MVFR VSBY WITH
IT. BEYOND THAT THE COLD AIR DOES COME AROUND 00Z IN AND THE
MOISTURE IS YET DEEP ENOUGH SO WE WILL SEE SNOW HERE SATURDAY NIGHT.
IT MAY NOT LAST MORE THAN A FEW HOURS BUT IT WILL IMPACT TAFS WITH
SOLID IFR VSBY/CIGS FOR THE I-96 TAFS.  BETWEEN THE RAIN BAND TOWARD
MORNING AND THE SNOW IN THE EVENING EXPECT SCATTERED SHOWERS....
WITH IFR CIGS.

&&

.MARINE...(330 PM EDT FRI APR 15 2011)
A GALE WARNING IS IN EFFECT FOR THE ENTIRE NEARSHORE WITH
EAST/OFFSHORE WINDS TO 35-40 KTS CONTINUING. THE WINDS WILL
GRADUALLY DECREASE AFTER 2 AM AS THE SURFACE LOW GETS CLOSER... WITH
GALES NO LONGER EXPECTED BY DAYBREAK SATURDAY. THE WINDS WILL TURN
IN A CLOCKWISE DIRECTION SAT AND SAT NIGHT AS THE LOW PASSES BY JUST
TO OUR WEST... AND WILL BEGIN CRANKING OUT OF THE WEST SAT NIGHT
ONCE THE LOW MOVES TO OUR NORTH. THAT WILL BUILD THE WAVES
SIGNIFICANTLY.

&&

.HYDROLOGY...(330 PM EDT FRI APR 15 2011)
RAIN AMOUNTS WITH THE SYSTEM TONIGHT/SATURDAY OF NEAR ONE HALF
INCH SHOULD NOT CREATE ANY SIGNIFICANT HYDRO ISSUES. SOME SLIGHT
RISES MAY OCCUR ON THE RIVERS OVER THE NEXT FEW DAYS.

THE SYSTEM ON TUESDAY AND TUESDAY NIGHT MAY CONTAIN MORE CONVECTION
AND QPF THAN THE ONE THIS WEEKEND... SO THAT WILL BE THE NEXT TIME
FRAME TO FOCUS ON FOR POTENTIAL HYDRO ISSUES.

&&

.GRR WATCHES/WARNINGS/ADVISORIES...
MI...NONE.
LM...GALE WARNING ENTIRE NEARSHORE THROUGH TONIGHT.
