NWS Grand Rapids, MI wrote its last area forecast discussion before the first event at Jun 15, 7:15 PM EST, 3 hours 40 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 815 PM EDT TUE JUN 15 2010 LATEST UPDATE...SHORT TERM... .SYNOPSIS...(410 PM EDT TUE JUN 15 2010) A LOW PRESSURE SYSTEM CENTERED EAST OF ST LOUIS AT 3 PM THIS AFTERNOON WILL HEAD NORTHEAST CROSSING THE LANSING AREA TOWARD MIDNIGHT. WIDESPREAD SHOWERS AND SCATTERED THUNDERSTORMS ARE EXPECTED ACROSS SOUTHWEST LOWER MICHIGAN BY EARLY TONIGHT. THUNDERSTORMS WILL BE MOSTLY SOUTH OF INTERSTATE 96. THE SYSTEM WILL MOVE EAST OF THE AREA BY WEDNESDAY MORNING AND BRING CLEARING SKIES BY EARLY AFTERNOON AS A HIGH PRESSURE SYSTEM BUILDS INTO SOUTHWEST LOWER MICHIGAN BEHIND THE STORM. HIGH PRESSURE WILL BRING PARTLY CLOUDY SKIES TO THE AREA THURSDAY. ANOTHER STORM SYSTEM HEADING INTO CENTRAL CANADA FROM THE NORTHERN PLAINS WILL PUSH A WARM FRONT THROUGH THE AREA EARLY FRIDAY BRINGING TEMPERATURES NEAR 90 FRIDAY AFTERNOON. THE TRAILING COLD FRONT WILL MOVE THROUGH THE AREA EARLY SATURDAY WITH A CHANCE OF THUNDERSTORMS. CLEARING SKIES WILL FOLLOW FOR SATURDAY AFTERNOON. && .SHORT TERM...(815 PM EDT TUE JUN 15 2010) (TONIGHT THROUGH THURSDAY) SENT AN UPDATE OUT MAINLY TO HIGHLIGHT HEAVY RAINFALL POTENTIAL. SEVERAL UPSTREAM REPORTS OF GREATER THAN ONE INCH OF RAIN IN LESS THAN AN HOUR ARE OCCURRING. PRECIPTABLE WATER VALUES WILL CONTINUE TO CLIMB TONIGHT TO VALUES OF OVER 2 INCHES. HEAVY RAINFALL THREAT WILL BE CWA-WIDE. AVERAGE RAINFALL WILL BE AROUND THREE QUARTERS OF AN INCH...BUT LOCALIZED 2-3 INCH TOTALS WILL BE POSSIBLE...WHICH COULD CAUSE SOME FLOODING ISSUES IN POOR DRAINAGE AREAS. THE HEAVY RAIN THREAT WILL DIMINISH AFTER 08-09Z. ONCE THE STORMS MOVE OUT OF THE AREA TOWARD MORNING PARTLY TO MOSTLY CLOUDY SKIES WITH CU/SC SHOULD PREVAIL DURING THE DAY. CLEARING WILL FOLLOW WEDNESDAY NIGHT AS THE SURFACE HIGH MOVES IN WITH ANTICYCLONIC LOW LEVEL WIND FLOW. CLEAR TO PARTLY CLOUDY SKIES SHOULD PREVAIL INTO THURSDAY AS THE HIGH SLOWLY MOVES EAST ACROSS SOUTHWEST LOWER MICHIGAN. THE WARM ADVECTION AHEAD OF THE NEXT SYSTEM COULD BRING THUNDERSTORMS TO OUR NW CWA THURSDAY NIGHT BUT THE LOW LEVEL JET IS WELL WEST OF MICHIGAN SO I WOULD NOT EXPECT TO MUCH IN THE WAY OF THUNDERSTORMS THURSDAY NIGHT ACTUALLY. && .LONG TERM...(410 PM EDT TUE JUN 15 2010) FRIDAY THROUGH TUESDAY) THE MAIN CHALLENGE IS ASSESSING PRECIPITATION CHANCES AND TIMING EARLY THIS COMING WEEKEND. FEW CHANGES WERE MADE TO THE CURRENT FORECAST. WE PRIMARILY USED HPC GUIDANCE. WEDNESDAY AND THURSDAY LOOK DRY WITH A RELATIVELY HIGH DEGREE OF CONFIDENCE AS A SHARP UPPER SHORTWAVE RIDGE APPROACHES. THIS RIDGE IS SHARPENED BY A DEEPENING TROUGH OVER THE NW UNITED STATES THAT DRAGS A COLD FRONT THROUGH THE AREA SATURDAY MORNING. EXPECT THE HIGHEST POPS FRIDAY NIGHT WITH A GOOD CHANCE OF THUNDER WITH ANY PRECIPITATION THAT OCCURS. GIVEN THE OVERALL AGREEMENT AMONG THE MODELS WITH THE STRENGTH AND TIMING OF THE PV ANOMALY THAT DRIVES THIS FRONT...THERE IS BETTER THAN AVERAGE CONFIDENCE FOR THE OCCURRENCE AND TIMING OF THE FRONTAL PASSAGE. AFTER SATURDAY...THE 15/12Z RUN OF THE ECMWF LEANS TOWARDS A DRY AND WARM SATURDAY-MONDAY WITH PRONOUNCED RIDGING AT THE SURFACE AND ALOFT. THE GFS SHOWS A MORE UNSETTLED ZONAL PATTERN ALOFT. THE OVERALL CONFIDENCE IN THE FORECAST DECREASES IN THE MONDAY TO TUESDAY TIMEFRAME DUE TO THESE DIFFERING SOLUTIONS...HOWEVER WE TEND TO FAVOR THE DRIER ECMWF SOLUTION THROUGH MONDAY. && .AVIATION...(800 PM EDT TUE JUN 15 2010) SHOWERS AND SCATTERED THUNDERSTORMS WERE MOVING INTO WRN LWR MI AT 00Z. THERE HAVE BEEN NUMEROUS REPORTS OF TORRENTIAL RAINFALL IN SRN WI AND NRN IL WITH THIS BATCH OF PRECIP. IF SOME OF THE SHOWERS REMAIN AT THIS INTENSITY AND IMPACT AN AIRPORT TERMINAL... VSBYS/CIGS WILL LIKELY TANK INTO THE IFR/LIFR CATEGORY. OTHERWISE CONDITIONS WILL BE PREDOMINATELY MVFR THROUGH 06Z. THE MAIN RISK OF THUNDER APPEARS TO BE SOUTH AND EAST OF GRR BETWEEN 01Z AND 06Z. BELIEVE IFR CONDITIONS WILL BECOME WIDESPREAD AFTER 06Z (MODERATE TO HIGH CONFIDENCE) AS THE HEAVIER RAINFALL PUSHES OUT OF THE REGION BUT THE SURFACE LOW TRACKS PRETTY MUCH OVERHEAD. WIDESPREAD IFR WILL PROBABLY CONTINUE THROUGH ABOUT MID MORNING WEDNESDAY BEFORE IMPROVING TO MVFR THEN POTENTIALLY VFR AFTER 18Z. && .MARINE...(410 PM EDT TUE JUN 15 2010 THUNDERSTORMS WILL BE THE PRIMARY ISSUE IN THE NEAR SHORE TONIGHT AS THE SURFACE SYSTEM MOVES THROUGH THE AREA. BEHIND THE SYSTEM...WINDS ARE EXPECTED TO BE IN THE 5 TO 15 KNOT RANGE SO SMALL CRAFT ADVISORIES WILL NOT BE NEEDED. THE HIGH MOVES IN WEDNESDAY NIGHT INTO THURSDAY SO WINDS WILL BE LIGHT. && .HYDROLOGY...(410 PM EDT TUE JUN 15 2010) I AM CONCERNED ABOUT URBAN AND SMALL STREAM FLOODING ISSUES TONIGHT DUE TO THE 2 INCHES OF PRECIPTABLE WATER OVER THE SOUTHERN SECTIONS OF THE CWA. WE WILL HAVE TO MONITOR THIS. OTHERWISE DRY WEATHER RETURNS WEDNESDAY BY MID DAY SO THAT WILL GIVE TIME FOR THE WATER TO RUN OFF BEFORE THE STORMS MOVE IN FRIDAY NIGHT AGAIN. && .GRR WATCHES/WARNINGS/ADVISORIES... MI....NONE.
