AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
1205 PM EDT WED JUN 22 2011
LATEST UPDATE...SHORT TERM...
.SYNOPSIS...(424 AM EDT WED JUN 22 2011)
A COLD FRONT WILL SWEEP THROUGH THE AREA THIS AFTERNOON AND EARLY
THIS EVENING. A FEW SHOWERS AND STORMS WILL REMAIN POSSIBLE AHEAD OF
THE FRONT THROUGH TODAY. THE BEST CHANCE WILL COME EAST OF U.S.-131
FROM MID TO LATE AFTERNOON WHERE THERE IS A LOW CHANCE OF SOME
SEVERE WEATHER.
SHOWERS WILL CONTINUE TO BE POSSIBLE THROUGH THE END OF THE WORK
WEEK AS THE SYSTEM REMAINS IN THE REGION. A FEW STORMS WILL BE
POSSIBLE...HOWEVER THEY SHOULD BE ON THE WEAK SIDE AND WILL BE FEW
AND FAR BETWEEN. COOLER WEATHER CAN BE EXPECTED INTO NEXT WEEK.
CONDITIONS WILL DRY OUT OVER THE WEEKEND AS HIGH PRESSURE BUILDS IN
ACROSS THE AREA.
&&
.SHORT TERM...(1205 PM EDT WED JUN 22 2011)
(THIS AFTERNOON THROUGH FRIDAY)
I JUST UPDATED THE ZONES /GRIDS TO INCREASE THE POP TO CONDITIONAL
EAST OF GRAND RAPIDS THIS AFTERNOON AS THERE AMPLE MOISTURE AND
INSTABILITY FOR STORMS DO DEVELOP AND CONTINUE EAST ON LINE AS THE
JET EXIT REGION MOVES OVER SW LOWER MICHIGAN IN CONJUNCTION WITH THE
UPPER COLD POOL.
I EXPECT SOME OF THE STORMS WILL BECOME SEVERE AS THEY AHEAD EAST
TOWARD I-69 DURING THE MID AFTERNOON. THE DEEP LAYER SHEAR WILL BE
BEST SOUTH OF I-94 THIS AFTERNOON BUT VERY WEAK NORTH OF I-96 AND
WEST OF US-131. THE STORMS SHOULD BE EAST OF THE CWA BY 4 PM OR SO.
THE WRAP AROUND SHOWERS AND LOW CLOUDS WILL MOVE IN EARLY TO MID
EVENING. THAT WILL END OUR SUMMER LIKE WEATHER FOR A FEW DAYS ANYWAY.
MOSTLY CLOUDY SKIES WITH LIGHT RAIN SHOWERS SHOULD PREVAIL INTO
THURSDAY NIGHT. SOME IMPROVEMENT IS EXPECTED FRIDAY AS THE UPPER
LEVEL SYSTEM MOVES EAST OF THE AREA.
&&
.LONG TERM...(424 AM EDT WED JUN 22 2011)
(FRIDAY NIGHT THROUGH TUESDAY)
H5 TROUGHING AND ASSOCIATED CLOUDINESS/COOL TEMPS ARE PROGGED TO
FINALLY LIFT OUT OF THE REGION ON SATURDAY. A FLATTER LOOKING H5
FLOW ALOFT AND SFC RIDGING LEAD TO A STRETCH OF NICE SUMMER WEATHER
FOR THE WEEKEND INTO EARLY NEXT WEEK. THE BELOW NORMAL TEMPERATURES
MODERATE TO NEAR NORMAL BY SUNDAY... AND TO ABOVE NORMAL BY TUESDAY.
THE RETURN OF 18-20C H8 TEMPS AND FAST ZONAL FLOW ALOFT MAY LEAD TO
A FEW STORMS BY TUESDAY.
&&
.AVIATION...(756 AM EDT WED JUN 22 2011)
NUMEROUS MVFR CIGS OF 1500-2500 FT OVER THE AREA AT 12Z ARE EXPECTED
TO LIFT TO VFR BY 14-15Z WED AS DEEPER MIXING QUICKLY DEVELOPS WITH
SOUTHERLY WINDS INCREASING TO 15G25KTS.
TSTMS ARE EXPECTED TO DEVELOP AGAIN DURING PEAK HEATING (AFTER
18-20Z)... PRIMARILY ALONG AND EAST OF HIGHWAY 131. WINDS GO MORE
SOUTHWESTERLY IN THE AFTERNOON AND THAT SHOULD KEEP THE LAKESHORE
(KMKG) STABLE WITH CB/S MAINLY WELL INLAND.
TSTM THREAT SHOULD END FROM WEST TO EAST BY 00Z-02Z THURSDAY... WITH
GUSTY SW WINDS DIMINISHING TO LESS THAN 10 KTS. MVFR TO IFR CIGS AND
SCATTERED SHOWERS ASSOCIATED WITH THE SFC LOW ARE EXPECTED TO SPREAD
IN FROM THE WEST AFTER 02Z OR SO... ALTHOUGH REACHING TOWARD LAN AND
JXN PROBABLY AFTER 06Z THUR.
&&
.MARINE...(424 AM EDT WED JUN 22 2011)
WE WILL BE ISSUING A SMALL CRAFT ADVISORY FOR THE ENTIRE NEARSHORE
THAT WILL BE VALID THROUGH 06Z TONIGHT. A DECENT GRADIENT IS IN
PLACE EARLY THIS MORNING...HOWEVER IT IS NOT BEING REALIZED DUE TO
THE STABLE EFFECTS FROM THE COOL LAKE AND WARM AIR MOVING IN. SOME
OF THE COASTAL OBSERVATIONS ARE APPROACHING CRITERIA ALREADY...SO WE
WILL HOIST THE ADVISORY. A BETTER CHANCE OF SOME THE HIGHER WINDS
MIXING DOWN WILL OCCUR LATER THIS AFTERNOON AND THIS EVENING AS THE
FRONT MOVES THROUGH AND COOLER AIR MOVES IN. WINDS WILL DIMINISH A
BIT BY DAYBREAK THU AS A WEAKER GRADIENT NEAR THE LOW MOVES IN.
WE COULD SEE A NEED FOR ANOTHER POSSIBLE ADVISORY THU AFTERNOON AND
EVENING ON THE SRN PERIPHERY OF THE SFC LOW THAT IS EXPECTED TO
MIGRATE TO OUR NORTH BY THEN.
&&
.HYDROLOGY...(424 AM EDT WED JUN 22 2011)
NUMEROUS COUNTIES REMAIN UNDER A FLASH FLOOD WARNING OR A FLOOD
ADVISORY FROM THE STORMS LATE YESTERDAY AFTERNOON AND EVENING. CALLS
TO COUNTY DISPATCH CENTERS LATE LAST EVENING INDICATED THAT
CONDITIONS WERE IMPROVING ACROSS THE AREA ONCE RAINS LET UP AND AS
STORM DRAINS BECAME UNPLUGGED. SOME PROBLEMS STILL EXISTED...AND WE
FELT IT WAS WISE TO EXTEND VALID TIMES OF EVERYTHING UNTIL LATE WED
MORNING TO GIVE THE DAY SHIFT AN OPPORTUNITY TO MAKE SOME CALLS AND
RE-EVALUATE THE SITUATION.
MORE SHOWERS AND STORMS WILL BE POSSIBLE TODAY...HOWEVER THE THREAT
FOR FLOODING IS DIMINISHING. THIS IS THE CASE AS THE AXIS OF DEEP
MOISTURE/HIGH PWAT VALUES IS IN THE PROCESS OF SHIFTING EAST. BY THE
TIME THE FRONT IS MOVING THROUGH THIS AFTERNOON...PWATS WILL BE DOWN
TO AROUND 1.25...COMPARED TO THE 1.75 TO 2.0 INCHES FROM YESTERDAY.
ANY PCPN WILL BE RATHER PROGRESSIVE...SO WE DO NOT ANTICIPATE ANY
ADDITIONAL SIGNIFICANT FLOODING ISSUES.
