AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
100 PM EDT FRI JUL 1 2011
LATEST UPDATE...AVIATION...
.SYNOPSIS...(1210 PM EDT FRI JUL 1 2011)
THUNDERSTORMS WILL BRING HEAVY RAIN WITH SOME FLOODING POSSIBLE. THE
STORMS WILL DIMINISH BY THIS EVENING WITH WARM AND HUMID WEATHER
OVERNIGHT. A COLD FRONT WILL BRING MORE STORMS ON SATURDAY...SOME OF
WHICH MAY BE SEVERE WITH STRONG WINDS...HAIL AND FLOODING RAINS.
COOLER AND DRIER WEATHER WILL FOLLOW FOR SUNDAY AND MONDAY.
&&
.SHORT TERM...(1210 PM EDT FRI JUL 1 2011)
(THIS AFTERNOON THROUGH SUNDAY)
HEAVY RAIN THREAT CONTINUES THIS AFTERNOON FROM SOUTH OF MUSKEGON
AND WEST OF GRAND RAPIDS. RAINFALL RATES OF 2 INCHES IN HALF AN HOUR
HAVE BEEN OBSERVED THIS MORNING NEAR MUSKEGON. FORTUNATELY THE
HEAVIEST RAIN HAS REMAINED OVER LAKE MICHIGAN WHERE THERE IS A LARGE
AREA OF STORM TOTAL RAINFALL IN EXCESS OF 6 INCHES.
STORMS SHOULD DIMINISH BY LATE AFTERNOON AS UPPER RIDGE AXIS MOVES
CLOSER AND CAPPING INVERSION FORMS AS WARM MID LEVEL AIR ADVECTS IN
ALONG WITH SUBSIDENCE. REST OF PREVIOUS FORECAST DISCUSSION FOLLOWS.
HARD TO FIND A GOOD TRIGGER FOR STORMS INTO TONIGHT. HOWEVER...AS
WAS THE CASE LAST NIGHT...THE STORMS MAY CONTINUE TO FAVOR THE LEAD
EDGE OF THE THETA-E GRADIENT AND THE EASTERN EDGE OF MID LEVEL CAP.
THIS WILL SHIFT TO THE SE PORTION OF THE CWA. HOWEVER...
PRECIPITABLE WATER VALUES BEGIN TO DROP OFF...SO THE THREAT OF
HEAVY RAIN WILL BE LOWER.
BY SATURDAY A COLD FRONT IS PROGGED TO BUMP INTO THIS MUGGY AIR
MASS. TIMING WILL BE KEY WITH THIS FRONT. SEEMS LIKE THE MODELS
WANT TO PUSH IT THROUGH TOWARD MID DAY WHICH WOULD MITIGATE SEVERE
POTENTIAL. HOWEVER AS IS OFTEN THE CASE...IT IS TOUGH TO PUSH A
COLD FRONT THROUGH WHILE THE HEATING OF THE DAY IS IN PROGRESS. SO
COULD EASILY SEE THE FRONT BEING DELAYED SOMEWHAT...WHICH WOULD
INCREASE THE SEVERE THREAT FOR THE AFTERNOON.
ADDED POPS TO THE SE CWA SATURDAY EVENING WITH THE SAME THINKING...
THAT THE FRONT MAY BE SLOWER TO COME THROUGH THAN THE MODELS
SUGGEST. VERY NICE DAY EXPECTED BY SUNDAY WITH HIGH PRESSURE
BUILDING IN. THIS WILL BRING SUNSHINE...SLIGHTLY COOLER TEMPS AND
LESS HUMIDITY.
&&
.LONG TERM...(441 AM EDT FRI JUL 1 2011)
(SUNDAY NIGHT THROUGH THURSDAY)
MODELS ARE IN DECENT AGREEMENT IN SHOWING HIGH PRESSURE IN CONTROL
OF THE WEATHER FOR THE MONDAY INTO TUESDAY TIME FRAME. WHILE IT
DOES BECOME SLIGHTLY UNSTABLE EACH AFTERNOON...BOTH THE MOISTURE AND
INSTABILITY APPEAR TOO LOW TO SUPPORT RAIN. WILL MAINTAIN THE DRY
FORECAST. AFTERNOON TEMPS SHOULD END UP A FEW DEGREES HIGHER THAN
NORMAL.
THE RISK FOR STORMS LOOKS GOOD FOR WEDNESDAY WITH THE MOISTURE PLUME
MOVING IN AHEAD OF THE COLD FRONT.
&&
.AVIATION...(100 PM EDT FRI JUL 1 2011)
PRIMARILY VFR CONDITIONS ARE ANTICIPATED THIS AFTERNOON BUT SOME
POCKETS OF MVFR TO IFR ARE LIKELY PARTICULARLY AT KGRR DUE TO
TSTORMS DRIFTING IN FROM THE NNW FOR MID AFTN. LINGERING LOW CLOUDS
WILL ALSO CONTINUE TO PRODUCE SOME IFR AT KMKG THIS AFTN.
CONDITIONS WILL LIKELY TRANSITION TO MAINLY MVFR OVERNIGHT DUE TO
FORMATION OF LIGHT FOG DUE TO INCREASING SFC DEW PTS AND RESIDUAL
BOUNDARY LAYER MOISTURE FROM EARLIER RAINFALL. SOME POCKETS OF
DENSER FOG ARE CERTAINLY POSSIBLE OVERNIGHT... BUT WAS NOT CONFIDENT
ENOUGH IN THAT TO OCCUR TO TAKE CONDITIONS DOWN TO IFR IN FOG AT
THIS TIME. THE BEST CHANCE FOR DENSER FOG WILL BE NEAR TO WEST OF
US-131 WHERE MOST OF THE RAIN HAS FALLEN THE PAST 18 HRS. THIS
NOTION IS ALSO CORROBORATED WITH SPC SREF PROBABALISTIC GUIDANCE OF
SFC VISBYS GOING BELOW 3 MILES.
FOG WILL GRADUALLY BURN OFF/MIX OUT BY MID SATURDAY MORNING.
SCATTERED SHOWERS AND PERHAPS A FEW STORMS SHOULD REDEVELOP FROM NW
TO SE ALONG AND JUST AHEAD OF THE COLD FRONT.
&&
.MARINE...(441 AM EDT FRI JUL 1 2011)
WILL POST A SMALL CRAFT ADVISORY FOR AREAS NORTH OF WHITEHALL
STARTING LATER THIS MORNING. SSW WINDS WILL INCREASE TODAY AS THE
PRESSURE GRADIENT TIGHTENS IN ADVANCE OF THE APPROACHING COLD
FRONT. SOUTH OF WHITEHALL THE FETCH WILL BE CONSIDERABLY LESS
MAKING FOR LOWER WAVES. THE WINDS SHOULD DIMINISH LATER TONIGHT AS
THE PRESSURE GRADIENT BECOMES BAGGY AGAIN PRIOR TO THE FRONT
ARRIVING.
&&
.HYDROLOGY...(441 AM EDT FRI JUL 1 2011)
HEAVY RAIN THREAT CONTINUES WITH PWAT VALUES HOLDING AROUND TWO
INCHES TODAY INTO THIS EVENING. HOWEVER THE MAIN THREAT SHOULD
MAINLY BE THIS MORNING AS THE STORMS ARE EXPECTED TO BECOME LESS
FOCUSED AS THE DRIVING LLJ WEAKENS TO OUR WEST. MORE STORMS ARE
POSSIBLE SATURDAY WITH A COLD FRONT...HOWEVER THESE TOO ARE EXPECTED
TO REMAIN SCATTERED...AND THE HEAVY RAIN THREAT WILL ONLY BE
LOCALIZED.
&&
.GRR WATCHES/WARNINGS/ADVISORIES...
MI...FLASH FLOOD WATCH THROUGH 4 PM TODAY FOR THE WRN TWO TIERS OF
THE GRR CWA.
