AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
356 AM EDT MON APR 9 2012

.SYNOPSIS...
ISSUED AT 356 AM EDT MON APR 9 2012

IT WILL BE ANOTHER WINDY AND COOL DAY TODAY. WE WILL SEE A MIX OF
CLOUDS AND SUN AND A FEW LIGHT RAIN SHOWERS MAY POP UP INTO THE
AFTERNOON. COOLER AIR WILL PUSH INTO THE REGION TONIGHT DROPPING
TEMPERATURES TOWARD THE FREEZING MARK. HOWEVER FROST IS NOT A
CONCERN AS THE WINDS WILL CONTINUE AND CLOUDS ARE EXPECTED TO FILL
IN. TOWARD DAYBREAK TUESDAY A FEW RAIN AND SNOW SHOWERS WILL BE
POSSIBLE AND THESE WILL REMAIN SCATTERED ABOUT THROUGH TUESDAY
EVENING. IT WILL BE A CHILLY TUESDAY WITH HIGHS ONLY IN THE 40S.
FROST AND FREEZE POSSIBILITIES EXISTS FOR TUESDAY NIGHT AND
WEDNESDAY NIGHT AS WINDS DECREASE AND SKIES CLEAR.

&&

.SHORT TERM...(TODAY THROUGH TUESDAY)
ISSUED AT 356 AM EDT MON APR 9 2012

THE SHORT WAVE THAT APPROACHES LATER TODAY LOOKS MORE SHEARED AND
GIVEN THE DRY AIR MASS OVERHEAD IT MAY BE DIFFICULT TO GENERATE
ANY SHOWERS. HAVE KEPT SLGT CHC POPS GOING ACROSS AREAS NORTH OF
I-96...AND REMOVED POPS SOUTH. OF MORE CONCERN WILL BE THE WINDS
TODAY. FORECAST SOUNDINGS SUGGEST EXCELLENT MIXING TODAY AND WE
MAY BE ABLE TO MIX DOWN FAIRLY STRONG WINDS...EVEN STRONGER THAN
YESTERDAY. THIS IS NOT A SLAM DUNK HOWEVER...SINCE THE POTENTIAL
FOR THE HIGHEST WINDS DOE SN/T OCCUR UNTIL MID TO LATE AFTERNOON.
HOW EFFICIENT THE MIXING WILL BE AT THIS TIME IS QUESTIONABLE IF
WE BEGIN TO CLOUD OVER. SO WILL LET THE DAY SHIFT MONITOR TRENDS
AS THE MORE SUNSHINE WE SEE THROUGH THE AFTERNOON THE HIGHER
LIKELIHOOD THAT A WIND ADVISORY MAY BE NEEDED.

BY TONIGHT AND INTO TUESDAY...THE MAINE UPPER LOW WILL BEGIN TO
RETROGRADE. THIS WILL CAUSE AN UPPER TROUGH TO PASS SOUTH THROUGH
THE CWA TUESDAY MORNING. THIS WILL RESULT IN COLDER AIR INVADING
THE AREA ALONG WITH DEEPER MOISTURE. H8 TEMPS DROP TO -9C BY 12Z
TUE WHICH WOULD BE COLD ENOUGH TO GENERATE SOME LAKE EFFECT. THE
MOISTURE DEPTH OVER THE LAKE WILL BE THE QUESTION...AS THE DEEPEST
MOISTURE REACHES CENTRAL LOWER...BUT MAY NOT BACK WEST OVER THE
LAKE. THEREFORE WILL KEEP THE LOW POPS GOING. BEST CHANCE OF PCPN
SHOULD ACTUALLY BE ACROSS THE NE CWA WHERE THE BEST MOISTURE
FLOATS IN. IT WILL BE A RAW TUESDAY WITH A FAIRLY STIFF NW WIND
AND THE PCPN SHOULD OCCASIONALLY MIX WITH SNOW.

.LONG TERM...(TUESDAY NIGHT THROUGH SUNDAY)
ISSUED AT 356 AM EDT MON APR 9 2012

THE ON GOING ISSUE OF FROST AND FREEZING TEMPERATURES WILL REMAIN AN
ISSUE MOST OF THIS WEEK SURFACE HIGH PRESSURES AND NORTHWEST FLOW
PREVAILS INTO THURSDAY. A MESSY SYSTEM FROM THE PACIFIC WILL BRING
THE THREAT OF STRONG THUNDERSTORMS AND LOCALLY HEAVY RAINFALL NEXT
WEEKEND. TIMING IS A PROBLEM THROUGH.

THE OVERALL CONFIDENCE FACTOR IN THIS FORECAST PERIOD IS HIGH
THROUGH THURSDAY THEN LESS SO BEYOND THAT (THE SYSTEM WILL IMPACT US
IT IS MORE A QUESTION OF WHEN THAN IF). OUR EASTERN TROUGH WITH HIGH
AMPLITUDE FLOW WILL CONTINUE THROUGH THURSDAY. FINALLY LATE IN THE
WEEK A SYSTEM CURRENTLY NEAR THE DATELINE OVER THE CENTRAL PACIFIC
BOOTS THE SYSTEM JUST OFF SHORE OF THE WEST COAST INLAND. THAT THEN
CREATES ISSUES AS TO JUST HOW THE SHORTWAVE ENERGY FROM THAT SYSTEM
MOVE INLAND TO DISPLACE THE UPSTREAM RIDGE OVER THE WEST CENTRAL
UNITED STATES. THE MODELS TYPICALLY DO POORLY WITH THIS SORT OF
PATTERN ON TIMING AND INTENSITY OF SHORTWAVES MOVING EAST INTO
SOUTHWEST MICHIGAN. ONE WAY OR THE OTHER THROUGH THIS ENERGY WILL
FIND ITS WAY HERE AND WE WILL SEE A CONSIDERABLE RAIN AND
THUNDERSTORM ACTIVITY. IT IS JUST A QUESTION OF TIMING. SINCE TIMING
IS AN ISSUE I HAVE HIGH CHANCE POPS SAT AND SUNDAY. I COULD SEE A
LEAD WAVE BRING INITIAL STORMS TO THE AREA LATE FRI OR EARLY
SATURDAY THEN THE MAIN SYSTEM COMING OUT SUNDAY OR MONDAY.

&&

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z MONDAY NIGHT)
ISSUED AT 110 AM EDT MON APR 9 2012

VFR CONDITIONS ARE EXPECTED THROUGH THE NEXT 24 HOURS. THE BIG
CONCERN WILL BE THE STRONG WESTERLY WINDS THAT WILL KICK IN BY MID
MORNING AND LAST INTO THE EVENING. GUSTS COULD OCCASIONALLY REACH
35 KTS WITH THE PEAK OCCURRING BETWEEN 18Z AND 22Z.

&&

.MARINE...
ISSUED AT 356 AM EDT MON APR 9 2012

WILL GO WITH A SCA STARTING THIS AFTERNOON. WEST WINDS WILL
INCREASE AND GRADUALLY BUILD WAVES. WILL GO WITH THE HEADLINE
THROUGH TONIGHT...HOWEVER WE MAY NEED TO EXTEND IT INTO TUESDAY
GIVEN THE ONSET OF THE COLD ADVECTION.

&&

.FIRE WEATHER...
ISSUED AT 356 AM EDT MON APR 9 2012

TODAY WILL BE SIMILAR TO SUNDAY WITH RATHER STRONG WINDS ALONG
WITH RH VALUES DROPPING TO AROUND 30 PERCENT. THIS WILL KEEP THE
FIRE DANGER ELEVATED DESPITE THE COOLISH TEMPS. THIS THREAT SHOULD
DIMINISH LATE TODAY AS A COOLER AND MORE MOIST AIR MASS MOVES IN.

&&

.HYDROLOGY...
ISSUED AT 356 AM EDT MON APR 9 2012

ANY SHOWERS OVER THE SHORT TERM WILL REMAIN LIGHT AND SCATTERED...
SO NO HYDRO ISSUES ARE FORESEEN.

&&

.GRR WATCHES/WARNINGS/ADVISORIES...
