AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 323 PM EDT WED JUN 27 2007 LATEST UPDATE...ALL EXCEPT AVIATION... .SYNOPSIS...(330 PM EDT WED JUN 27 2007) AREA OF LOW PRESSURE WILL SLIDE INTO WESTERN QUEBEC WITH A COLD FRONT STRETCHING SOUTHWEST THROUGH OSCODA...BIG RAPIDS...AND MILWAUKEE WISCONSIN. A BROKEN LINE OF SHOWERS AND THUNDERSTORMS HAVE DEVELOPED THIS AFTERNOON AHEAD OF THE FRONT ACROSS SOUTHWEST LOWER MICHIGAN...AND MOVING EAST. && .SHORT TERM... (330 PM EDT WED JUN 27 2007) BULK SHEAR VALUES GRADUALLY INCREASE TO 15 TO 25 KNOTS LATE THIS AFTERNOON...HOWEVER THEY QUICKLY VEER NORTHWEST. WEAK CONFLUENT REGION WAS FOCUSED ALONG INTERSTATE 94 CORRIDOR THROUGH 00Z WITH MID LEVEL LAPSE RATES AT 5.5 DEGREES C/KM SUGGESTING AN UNFAVORABLE ENVIRONMENT FOR DAMAGING WINDS. MARGINAL PRESSURE CHANGE HAS BEEN OBSERVED THE PAST FEW HOURS...WITH A CENTER FOCUSED JUST SOUTH OF KALAMAZOO COULD RESULT IN A WAKE LOW ENVIRONMENT. PRECIPITABLE WATER VALUES POKE UP TOWARDS 2 INCHES...THEN SHARPLY FALL BY 02Z THURSDAY. MAIN THREAT THROUGH LATE THIS AFTERNOON AND EARLY EVENING WILL BE WIND AND RAIN. MID LEVEL SUBSIDENCE BEHIND THE FRONT WILL HELP ERODE CLOUDS WITHIN THE BOUNDARY LAYER. MIXED LAYER THURSDAY WILL TAP CONSIDERABLY DRIER AIR...HOWEVER STILL EXPECT A FEW DIURNALLY DRIVEN CUMULUS TO DEVELOP. HIGH PRESSURE WILL SLIDE ACROSS WINNIPEG...ALLOWING WEAK NORTH TO SLIGHTLY NORTHEAST SURFACE WINDS ACROSS SOUTHWEST LOWER MICHIGAN. WEAK DOWNSLOPE EFFECT COULD SETUP WARMEST TEMPERATURES ALONG LAKESHORE THURSDAY AFTERNOON. AS HIGH PRESSURE BUILDS INTO THE GREAT LAKES...EXPECT ENOUGH HEAT RELEASE TO PROVIDE COOL NIGHTS. OVERNIGHT LOWS SHOULD EASILY FALL INTO THE 50S...TO MIDDLE 40S ALONG AND NORTH OF HIGHWAY 10. && .LONG TERM... (330 PM EDT WED JUN 27 2007) THE ISSUE FOR THE EXTENDED PERIOD...SATURDAY JUNE 30 TO WEDNESDAY JULY 4TH...IS THE SHORTWAVE TROUGH MOVING THROUGH AT THE END OF THE PERIOD. UNFORTUNATELY...THERE IS STILL A LOT OF UNCERTAINTY WITH THIS FEATURE AND A CHANCE OF THUNDERSTORMS IS POSSIBLE FOR BOTH TUESDAY AND WEDNESDAY. FOR SATURDAY THROUGH MONDAY...HIGH PRESSURE WILL BRING DRY AND SEASONABLY COOL WEATHER. MORNING LOWS IN THE 40S ARE LIKELY ACROSS THE NORTHERN INTERIOR AGAIN ON SUNDAY MORNING AFTER A COOL MORNING SATURDAY. IT SHOULD BEGIN TO WARM UP ON MONDAY AS THE SFC RIDGE MOVES EAST AND RETURN FLOW BEGINS. THE GFS HAS BEEN CONSISTENTLY SHOWING MCS ACTIVITY OVER THE UPPER MIDWEST ON MONDAY...SHIFTING INTO LOWER MICHIGAN DURING TUESDAY AND WEDNESDAY. HOWEVER...RUN TO RUN CONSISTENCY ON THE DETAILS ARE NOT GOOD...AND THERE HAS BEEN DISAGREEMENT WITH THE OPERATIONAL GFS AND THE ECMWF. THE 12Z GFS HAS TRENDED CLOSER TO THE ECWMF...WHICH WOULD KEEP MORE RIDGING IN FOR TUESDAY...THEN BRING THE MAIN BATCH OF CONVECTION THROUGH ON THE FOURTH OF JULY. SO WITH THAT IN MIND...WILL BUMP UP MAXES ON TUESDAY AND CONTINUE CHANCE POPS INTO WEDNESDAY. && .AVIATION...(130 PM EDT WED JUN 27 2007) TWO ROUNDS OF WEATHER TO EXPRESS IN THE 18Z TAFS...BOTH IN THE FIRST FEW HOURS. FIRST BATCH OF TSRA ATTM IS ASSOCIATED WITH THE REMNANT UPPER LOW CIRCULATION AND WILL CONTINUE FROM LAN TO AZO NEXT HOUR OR TWO THEN THE COLD FRONT MOVES THROUGH BETWEEN 19 AND 22Z...BRINGING MORE SHOWERS AND THUNDERSTORMS. SOME STRATUS WITH CEILINGS AROUND 3000 FEET ATTEND THE FRONT. THINGS SHOULD FINALLY START TO CLEAR OUT AFTER 23Z AS MUCH DRIER AIR BEHIND THE FRONT MOVES IN. && .MARINE... (330 PM EDT WED JUN 27 2007) WINDS WILL GRADUALLY SHIFT TO THE WEST AND NORTHWEST BEHIND FRONTAL PASSAGE. COLD AIR ADVECTION WILL KICK WAVES TO AROUND 2 TO 4 FEET. RIP CURRENTS MAY BE POSSIBLE ALONG BREAKPOINTS THURSDAY WITH A SEMI-PARALLEL WIND COMPONENT. && .HYDROLOGY... (330 PM EDT WED JUN 27 2007) PRECIPITABLE WATER VALUES HAVE RISEN TO NEAR 2 INCHES AHEAD OF THE FRONT. SLOW MOVING SHOWERS AND THUNDERSTORMS...WITH OCCASIONAL NEW DEVELOPMENT OVER ALREADY MOIST SOILS FROM EARLIER SHOWERS...COULD RESULT IN LOCALIZED FLOODING. PONDING OF WATER IN LOW LYING AREAS AND/OR URBAN AND SMALL STREAM FLOODING COULD OCCUR IN ANY PERSISTENT DOWNPOURS THROUGH THIS AFTERNOON AND EARLY EVENING. && .GRR WATCHES/WARNINGS/ADVISORIES...
