AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
752 AM EDT SUN APR 15 2012

.SYNOPSIS...
ISSUED AT 401 AM EDT SUN APR 15 2012

SHOWERS AND THUNDERSTORMS WILL AFFECT MOST OF THE AREA THIS
MORNING AS A WARM FRONT MOVES THROUGH THE AREA. MOST OF THE
SHOWERS AND STORMS SHOULD LIFT NORTH OF THE AREA BY THIS
AFTERNOON. SOME CLEARING SHOULD TAKE PLACE...AND TEMPERATURES WILL
RISE INTO THE 70S. A STRONG COLD FRONT WILL THEN BRING THE CHANCE
OF MORE SHOWERS AND STORMS TO THE AREA THIS EVENING AND TONIGHT.
THERE IS A CHANCE SOME OF THE STORMS COULD BE STRONG TO SEVERE
TONIGHT.

AFTER A BREAK IN THE RAIN DURING THE MORNING HOURS ON MONDAY...
SHOWERS WILL MOVE BACK INTO THE AREA LATE MONDAY AFTERNOON. MUCH
COOLER AIR WILL ALSO MOVE BACK IN.

&&

.SHORT TERM...(TODAY THROUGH MONDAY)
ISSUED AT 401 AM EDT SUN APR 15 2012

MAIN SHORT TERM CONCERNS IN THIS FORECAST PACKAGE WILL BE
CONVECTIVE TRENDS...SEVERE WEATHER POTENTIAL...AND WIND POTENTIAL
THROUGH THE PERIOD.

FIRST THING TO DEAL WITH THIS MORNING IS THE CONVECTIVE ACTIVITY
THAT IS MOVING IN ACROSS THE CWFA EARLY THIS MORNING. SOME OF THE
CONVECTION IS REMNANTS OF SOME OF THE SEVERE STORMS THAT OCCURS
ACROSS NE AND IA YESTERDAY AND LAST EVENING. THESE STORMS WERE
ACTUALLY A DECENT BOW A FEW HOURS AGO. THEY HAVE WEAKENED
CONSIDERABLY...WHILE EVOLVING INTO MORE OF A EAST/WEST BAND THAT
IS PARALLEL TO THE WARM FRONT.

THE STORMS ARE NOT EXPECTED TO GET OUT OF HAND THIS MORNING. EVEN
THOUGH WE HAVE WARM AND MOIST AIR ADVECTING IN ALOFT...THE POOL OF
INSTABILITY ADVECTING IN IS WEAKENING. THAT COMBINED WITH A STABLE
LOW LEVEL ENVIRONMENT WILL DOMINATE...AND SHOULD KEEP THESE STORMS
FROM PRODUCING MUCH...IF ANY IN THE WAY OF SEVERE WEATHER...EVEN
WITH GOOD DEEP LAYER SHEAR VALUES OF OVER 50 KNOTS.

THESE STORMS WILL CONTINUE TO MOVE EAST OVER THE NEXT COUPLE OF
HOURS WITH THE LLJ...BEFORE EVERYTHING BEGINS TO SHIFT NORTH AS
THE WARM FRONT MOVES NORTH. AROUND OR JUST AFTER DAYBREAK THIS
MORNING...THE LLJ WILL MOVE EAST...AND WE WILL SEE THE NORTHWARD
SURGE IN THE CONVECTION NOW ACROSS CENTRAL IA SHIFT THE CONVECTION
NORTH OF OUR AREA. MOST OF THE AREA SHOULD DRY OUT...AND EVEN
PARTIALLY CLEAR THIS AFTERNOON. WITH SOME SUN...WE SHOULD SEE
TEMPS WARM WELL INTO THE 70S WITH H850 TEMPS AROUND 13C OR SO. THE
ATMOSPHERE SHOULD BE MOSTLY CAPPED FOR A FEW HOURS...ONLY NEEDING A
LOW CHC POP IN THOUGH THE AFTERNOON.

WE WILL SEE THE THREAT FOR CONVECTION INCREASE THIS EVENING...AND
ESPECIALLY INTO THE OVERNIGHT HOURS TONIGHT. CONVECTION IS
EXPECTED TO FIRE ACROSS WI AHEAD OF THE FRONT WHERE THE BEST SFC
BASED INSTABILITY WILL BE. DEEP LAYER SHEAR WILL BE GREATER THAN
55 KNOTS THERE AND 0-1KM HELICITY VALUES WILL BE IMPRESSIVE...OVER
400 ACROSS WI. SEVERE WX IS LIKELY THERE...BUT SHOULD DIMINISH IN
INTENSITY A BIT AS ANYTHING WITH THE FRONT WILL MOVE IN. THE LAKE
SHOULD TEMPER SOME OF IT...ALONG WITH THE LOSS OF DIURNAL HEATING.
WE WILL NEED TO MONITOR THE SITUATION TONIGHT WITH THE STRONG WIND
FIELDS IN PLACE.

THE FRONT SHOULD EXIT THE CWFA AROUND 12Z OR SO ON MON MORNING.
ANY PCPN SHOULD MOVE OUT SHORTLY AFTER THAT. WE WILL GET INTO THE
DRY SLOT MON MORNING. WE SHOULD SEE WINDS PICK UP QUITE A BIT MON
MORNING WITH VERY GOOD MIXING TAKING PLACE. WINDS WILL PICK UP
MORE MON AFTERNOON AS STRONG CAA TAKES PLACE WITH THE WRAP AROUND
MOISTURE ROTATING BACK IN. THIS WILL ALSO INCREASE THE CHC OF RAIN
SHOWERS AGAIN. WINDS AT 2K FEET MON AFTERNOON ARE IN THE 40 KNOT
RANGE WHICH SHOULD BE ABLE TO BE MIXED DOWN SOME. WE COULD BE
LOOKING AT A WIND ADVISORY FOR MOST OF THE AREA FOR MON.

.LONG TERM...(MONDAY NIGHT THROUGH SATURDAY)
ISSUED AT 401 AM EDT SUN APR 15 2012

YET ANOTHER ROUND OF FROST/FREEZE POTENTIAL IS IN THE OFFING FOR
MONDAY NIGHT AND TUESDAY NIGHT AS COLD AND DRY HIGH PRESSURE IMPACTS
THE REGION. WINDS LOOK TO STAY UP MUCH OF MONDAY NIGHT... SO THE
BEST THREAT OF A WIDESPREAD FROST WILL BE ON TUESDAY NIGHT WHEN THE
WINDS WILL BE LIGHT/CALM WITH THE SFC HIGH OVERHEAD.

THE NEXT FRONTAL BOUNDARY CROSSES THE REGION WEDNESDAY NIGHT AND
EARLY THURSDAY... BUT DOES NOT LOOK TO CARRY MUCH OF A THUNDER
POTENTIAL DUE TO VERY LIMITED INSTABILITY. THAT SFC BOUNDARY SLIPS
SOUTH OF MI THURSDAY... THEN IT IS UNCLEAR WHETHER IT WILL STAY OF
MI FRIDAY AND SATURDAY OR REBOUND NORTH AS A WARM FRONT. RIGHT NOW
IT APPEARS WE STAY ON THE COOL SIDE OF THE FRONT WITH COOL/DRY LOW
LEVEL NE FLOW.

&&

.AVIATION...(FOR THE 12Z TAFS THROUGH 12Z MONDAY MORNING)
ISSUED AT 752 AM EDT SUN APR 15 2012

SCATTERED TSTMS AND IFR CONDITIONS WILL BE LIFTING OUT THIS
MORNING... WITH PREDOMINATELY VFR DEVELOPING FOR THIS AFTERNOON
AND EVENING AS SFC WARM FRONT LIFTS NORTH. THE MAIN ISSUE WILL BE
THE STRONG/GUSTY SOUTHERLY SFC WINDS TODAY AND TONIGHT... REACHING
30 KNOTS AT TIMES. MORE TSTMS ARE POSSIBLE AFTER MIDNIGHT TONIGHT
AND THESE MAY PRODUCE SFC WIND GUSTS IN EXCESS OF 40 KNOTS.

&&

.MARINE...
ISSUED AT 401 AM EDT SUN APR 15 2012

WEE WILL BE HOLDING ON TO THE SMALL CRAFT ADVISORY FOR TODAY AND
THIS EVENING. WE ARE NOW PLANNING ON ISSUING A GALE WATCH FOR THE
ENTIRE NEARSHORE FOR LATER TONIGHT AND MONDAY. WE SHOULD SEE WINDS
INCREASE IMMEDIATELY BEHIND THE FRONT WITH A SURGE OF COOLER AIR
AND PRESSURE RISES BEHIND THE FRONT. THE SECONDARY SHOT OF COLDER
AIR MONDAY AFTERNOON COMBINED WITH WINDS ABOVE 35 KNOTS JUST ABOVE
THE SFC SHOULD ALLOW FOR FREQUENT WIND GUSTS ABOVE GALE CRITERIA.
THIS WILL CONTINUE UNTIL MONDAY EVENING WHEN WE SHOULD SEE THE
WINDS DIMINISH.

&&

.HYDROLOGY...
ISSUED AT 401 AM EDT SUN APR 15 2012

THE MAIN RAINFALL WITH THIS SYSTEM SHOULD COME THIS MORNING AS WE
SEE CONVECTION DIMINISH AS IT COMES INTO THE AREA. THIS SHOULD
BRING GENERALLY 0.25 TO 0.75 INCHES OF RAINFALL TO THE AREA WITH
LOCALLY HIGHER AMOUNTS POSSIBLE. THIS AMOUNT OF RAINFALL WILL
BRING RIVER AND STREAM LEVELS UP SOME...HOWEVER ALL LEVELS ARE
STARTING OUT BELOW AVERAGE WITH THE RECENT LACK OF RAINFALL.

WE WILL SEE ANOTHER 0.25 INCHES TONIGHT AND LIGHT AMOUNTS MON
AFTERNOON AND EVENING. AGAIN...THIS SHOULD NOT CREATE ANY BIG
PROBLEMS ON AREA WATERWAYS.

&&

.GRR WATCHES/WARNINGS/ADVISORIES...
MI...NONE.
LM...GALE WATCH FROM MONDAY MORNING THROUGH MONDAY EVENING FOR
     LMZ844>849.

     SMALL CRAFT ADVISORY UNTIL 11 AM EDT MONDAY FOR LMZ844>849.
