AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
340 PM EDT SUN MAY 29 2011

LATEST UPDATE...MESOSCALE...

.SYNOPSIS...(401 AM EDT SUN MAY 29 2011)
A WARM FRONT WILL BE APPROACHING LOWER MICHIGAN FROM THE SOUTH
DURING THE DAY TODAY. SHOWERS AND THUNDERSTORMS ARE EXPECTED TO
DEVELOP ALONG THE WARM FRONT AND MOVE IN ACROSS SOUTHERN LOWER
MICHIGAN. SOME OF THESE STORMS COULD BECOME SEVERE. THE WARM FRONT
WILL MOVE NORTH OF THE AREA BY MONDAY...AND ALLOW FOR A VERY WARM
AIR MASS TO MOVE OVER LOWER MICHIGAN. HIGHS IN THE UPPER 80S TO
LOWER 90S CAN BE EXPECTED ACROSS MOST OF THE AREA MONDAY AND TUESDAY.

&&

.MESOSCALE...(340 PM EDT SUN MAY 29 2011)

MIXED LAYER CAPE SHOWS INCREASING CAPE VALUES AHEAD OF THE COMPLEX
ALONG INTERSTATE 94 WITH VALUES UP AROUND 2000 J/KG.  DEEP LAYER
SHEAR WAS UP TO 50 KNOTS SUPPORTING ORGANIZED CONVECTION.  THE SFC
TO 1 KM SHEAR AXIS HAS INCREASED TO 25 KNOTS INTO VAN BUREN COUNTY
SUGGESTING AN INCREASED RISK FOR TORNADOES ALONG THE INTERSTATE 94
CORRIDOR.  THE SFC FLOW REMAINS BACKED IN THIS REGION.

PRECIPITABLE WATER VALUES HAVE INCREASED TO 1.9 INCHES WITH THE
COMPLEX AND MOISTURE TRANSPORT REMAINS HIGH ON THE SOUTHWEST SIDE OF
THE COMPLEX WHERE NEW DEVELOPMENT WAS OCCURRING.  THUS THE FLASH
FLOOD RISK IS INCREASING WITH THIS EVENT.

&&

.SHORT TERM...(401 AM EDT SUN MAY 29 2011)
(TODAY THROUGH TUESDAY)
MAIN CONCERNS THROUGH THE SHORT TERM ARE THE CONVECTION TRENDS AND
SEVERE WX POTENTIAL FOR TODAY WITH THE WARM FRONT...AND THEN AGAIN
ON TUESDAY WITH THE COLD FRONT.

THE FRONTAL SYSTEM THAT WAS SUPPOSED TO BE BRINGING US A ROUND OF
CONVECTION EARLY THIS MORNING HAS DROPPED FURTHER SOUTH THAN
ANTICIPATED DUE TO THE ROBUST WAVE OF CONVECTION ACROSS IN AND OH ON
SAT. THE FRONT CURRENTLY EXTENDS IN AN ARC ALONG A KSTL AND KIND
LINE AS OF 08Z THIS MORNING. THE FRONT IS SHOWING SIGNS OF TURNING
NORTH AS A WARM FRONT AS THERE IS CONVECTION DEVELOPING NORTH OF THE
FRONT ACROSS KS...MO...IL...AND IN. THE WARM ADVECTION ALOFT OVER MI
IS TRYING TO PRODUCE A FEW LIGHT SHOWERS...BUT THEY ARE NOT ABLE TO
SUSTAIN THEMSELVES ATTM.

WE ARE EXPECTING THE WARM FRONT TO CONTINUE TO MOVE NORTH AS THE
UPPER RIDGE BUILDS JUST TO OUR WEST IN RESPONSE TO THE DIGGING LOW
OUT WEST. THIS RIDGE BUILDING SHOULD NOW OVERRIDE ANY OUTFLOWS FROM
CONVECTION...AND HELP TO PUSH THE WARM FRONT NORTH. THE CONVECTION
THAT IS FIRING ALONG THE FRONT NOW IS SHOWN BY THE MODELS TO
TRANSLATE INTO THE SRN PORTION OF THE CWFA LATER THIS MORNING AND
THIS AFTERNOON AS THE WARM FRONT HEADS NORTH.

WE EXPECT SCATTERED CONVECTION TO DEVELOP JUST NORTH OF THE
FRONT...AND WE COULD SEE A LINE OR TWO ORGANIZE TO OUR WEST AND MOVE
IN THIS AFTERNOON AND THIS EVENING. STRONG DEEP LAYER SHEAR OF
AROUND 40+ KNOTS ALIGNED WITH THE STORM MOTION WILL HELP THE STORMS
TO MOVE PRETTY GOOD TO THE ENE. THESE STORMS WILL BE SOMEWHAT
ELEVATED...BUT THE INVERSION WILL NOT BE EXCEPTIONALLY STRONG OR
DEEP...SO WE COULD SEE SOME WIND DAMAGE OCCUR FROM THESE STORMS. WE
ALSO CAN NOT RULE OUT A TORNADO NEAR THE FRONT WITH THE DECENT
DIRECTIONAL WIND SHEAR/HELICITY IN THE LOWER LEVELS. LCL/S SHOULD
ALSO BE SOMEWHAT LOW WITH THE MOIST AIR MASS IN PLACE.

WE WILL SEE THE BIGGEST PUSH OF THE FRONT TO THE NORTH THIS EVENING
AND OVERNIGHT AS THE UPPER RIDGE GETS BUILT UP QUITE A BIT. THIS
WILL TAKE THE WARM FRONT NORTH OF THE AREA...AND ESSENTIALLY END THE
PCPN/SEVERE THREAT. THE ATMOSPHERE BECOMES CAPPED BETWEEN 850 MB AND
700 MB AS TEMPS IN THAT LAYER WARM TO ALMOST THE MID TEENS C. 850 MB
TEMPS ARE EXPECTED TO WARM TO AROUND 20C OR LOWER 20S BY MON
AFTERNOON. WITH A GOOD DEAL OF SUN AROUND...THIS WILL SUPPORT HIGHS
IN THE LOWER 90S. THIS RIDGE WILL HOLD IN PLACE UNTIL EARLY
TUE...AND SUPPORT DRY WX AND HOT TEMPS UNTIL TUE AFTERNOON.

TUE AFTERNOON...THE UPPER RIDGE WILL BREAK DOWN...AND ALLOW THE
STRONG UPPER SYSTEM TO MISS US TO THE NW. WE WILL INITIALLY BE
CAPPED ON TUE...AND THAT SHOULD BREAK DOWN AS THE UPPER LOW IS IN
THE REGION. THE COLD FRONT IS CURRENTLY SHOWN TO COME IN JUST AFTER
PEAK HEATING...AND SHOULD BE ABLE TO TAKE ADVANTAGE OF STRONG
RESIDUAL INSTABILITY. WIND FIELDS ALOFT ON THE PERIPHERY OF THE
UPPER LOW WILL BE INCREASING...AND DEEP LAYER SHEAR WILL INCREASE AS
A RESULT TO 35 KNOTS BY 00Z WED AND HIGHER BEYOND. WE COULD BE
LOOKING AT A DECENT SEVERE WX EVENT TUE AFTERNOON IF THE FRONT CAN
COME IN JUST EARLY ENOUGH BEFORE DIURNAL INSTABILITY IS LOST.

&&

.LONG TERM...(401 AM EDT SUN MAY 29 2011)
(TUESDAY NIGHT THROUGH SATURDAY)
00Z GFS AND ECMWF ARE IN DECENT AGREEMENT SHOWING THE FRONT THROUGH
BY 12Z WEDNESDAY. SHOULD BE A PERIOD OF DRY WEATHER FOR WEDNESDAY
AND MAYBE THURSDAY...BUT WARM AIR ADVECTION AND SOME WEAK MOISTURE
RETURN MAY BRING A FEW SHOWERS IN BY THURSDAY NIGHT. LEFT THOSE
PERIODS DRY BUT ADDED SLIGHT CHANCE POPS FOR FRIDAY BASED ON MODEL
TRENDS AND TO MATCH WITH SURROUNDING OFFICES.

&&

.AVIATION...(140 PM EDT SUN MAY 29 2011)
EXPECTING GENERALLY MVFR CONDITIONS ACROSS THE AREA WITH IFR
CONDITIONS THROUGH 22Z IN STRONG TO SEVERE THUNDERSTORMS...
ESPECIALLY FOR THE SOUTHERN TAF SITES. RAIN WITH A FEW THUNDERSTORMS
WILL CONTINUE INTO THE EARLY EVENING. LIGHT FOG IS EXPECTED TO FORM
AGAIN TONIGHT WITH DECREASING CLOUD COVER. WINDS WILL BE LIGHT
EXCEPT NEAR THE STORMS... WHERE STRONG GUSTY WINDS OVER 60 KNOTS ARE
POSSIBLE.

&&

.MARINE...(401 AM EDT SUN MAY 29 2011)
THE BIGGEST CONCERN FOR MARINE INTERESTS CONTINUES TO BE THE FOG IN
PLACE OVER THE LAKE. THE VERY WARM AND MOIST AIR MASS MOVING IN OVER
THE COOL LAKE WATERS IS HELPING TO PRODUCE THIS FOG. THIS WILL
LIKELY CONTINUE TO BE THE CASE THROUGH MOST OF TUESDAY. WINDS ARE
NOT EXPECTED TO BE A MAJOR PROBLEM THROUGH THIS EVENING. WINDS WILL
PICK UP TONIGHT AS A STRONGER GRADIENT MOVES IN PLACE ACROSS LAKE
MICHIGAN. WE COULD BE LOOKING AT A SMALL CRAFT ADVISORY BEING NEEDED
BY MONDAY MORNING. WINDS LOOK LIKE THEY WILL THEN REMAIN UP THROUGH
WEDNESDAY BEFORE WINDS DIMINISH.

&&

.HYDROLOGY...(401 AM EDT SUN MAY 29 2011)
MAIN PERIOD OF CONCERN FOR HYDROLOGY IS TODAY. NICE PLUME OF DEEP
MOISTURE JUST NORTH OF THE WARM FRONT WITH PRECIPITABLE WATERS
BETWEEN 1.5 AND 1.75 INCHES...WILL MOVE OVER THE AREA BY THIS
AFTERNOON AND WILL REMAIN INTO THIS EVENING BEFORE SHIFTING NORTH.
WHILE THIS PLUME OF DEEP MOISTURE IS OVERHEAD...WE COULD SEE SOME
TRAINING OF STORMS THAT WOULD BE CAPABLE OF PRODUCING HEAVY RAIN.
WHERE THIS SETS UP...AND HOW LONG IT WOULD SIT IN ONE PLACE IS STILL
A BIT UNCERTAIN...ENOUGH TO KEEP FROM ISSUING A WATCH FOR NOW. BASIN
AVERAGES SHOULD BE UP TO AROUND AN INCH...HOWEVER LOCAL AREAS COULD
SEE HIGHER AMOUNTS.

ONCE THE RAIN SHIFTS NORTH OF THE AREA TONIGHT...WE WILL SEE A BREAK
IN THE RAINFALL. THE FOCUS WILL THEN BE SHIFTED TO THE RIVER
FORECAST POINTS AS RIVERS ARE ALREADY HIGH...ESPECIALLY ACROSS THE
SOUTH. AS ALL OF THE RUNOFF GETS INTO THE SYSTEM...SOME HEADLINES
MAY BE NEEDED FOR SOME OF THE RIVER FORECAST POINTS.

&&

.GRR WATCHES/WARNINGS/ADVISORIES...
MI...FLOOD WATCH IN EFFECT THROUGH LATE TONIGHT FOR MUCH OF SRN
LOWER MI.
LM...DENSE FOG ADVISORY ST. JOE TO MANISTEE THROUGH SUNDAY NIGHT.
