NWS Grand Rapids, MI wrote its last area forecast discussion before the first event at Jun 13, 3:54 PM EST, 1 hour 51 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 454 PM EDT SAT JUN 13 2015 LATEST UPDATE... MESOSCALE DISCUSSION .MESOSCALE DISCUSSION... ISSUED AT 454 PM EDT SAT JUN 13 2015 ISOLATED SHOWERS ARE BEGINNING TO DEVELOP JUST AHEAD OF THE WARM FRONT...WHICH AT 445 PM WAS FROM AROUND SOUTH HAVEN TO KALAMAZOO. MIXED LAYER CAPES ARE NEAR 1500 J/KG JUST SOUTH OF THE WARM FRONT OVER VAN BUREN COUNTY STREAMING INTO THIS BOUNDARY. I WOULD EXPECT TO SEE AN INCREASE IN COVERAGE OF STORMS ALONG THIS BOUNDARY OVER THE NEXT TWO HOURS. LOCALLY HEAVY RAIN... GUSTY WINDS AND HAIL ARE POSSIBLE FROM THESE STORMS. && .SYNOPSIS... ISSUED AT 329 PM EDT SAT JUN 13 2015 A WARM FRONT WILL PUSH NORTHWARD THROUGH THE FORECAST AREA OVERNIGHT. THAT WILL BRING WIDESPREAD SHOWERS AND THUNDERSTORMS TO THE AREA WITH LOCALLY HEAVY RAINFALL POSSIBLE. A COLD FRONT WILL THEN PUSH ACROSS THE AREA DURING SUNDAY CONTINUING THE THREAT OF SHOWERS AND THUNDERSTORMS. THE THREAT OF THUNDERSTORMS WILL END FROM WEST TO EAST DURING THE AFTERNOON AS THE COLD FRONT MOVES THROUGH THE AREA. IT SHOULD BE WARMER SUNDAY WITH HIGHS IN THE LOWER 80S. A STRONGER COLD FRONT WILL MOVE THROUGH THE AREA MONDAY BRINGING A RENEWED THREAT FOR SHOWERS AND THUNDERSTORMS. HIGH PRESSURE WILL MOVE IN FOR TUESDAY AND WEDNESDAY BRINING SLIGHTLY COOLER AND DRIER CONDITIONS TO THE AREA. && .SHORT TERM...(THIS EVENING THROUGH MONDAY NIGHT) ISSUED AT 329 PM EDT SAT JUN 13 2015 WE ARE WATCHING THE CONVECTION TO OUR SOUTH AND WEST TO SEE HOW MUCH OF IT REACHES SOUTHWEST MICHIGAN OVERNIGHT. WE THEN TURN OUR ATTENTION TO THE POTENTIAL FOR CONVECTION SUNDAY AS THE COLD FRONT MOVES THROUGH THE AREA. ADDITIONAL STORMS ARE POSSIBLE MONDAY AS A CANADIAN POLAR FRONT MOVES INTO THE AREA. TONIGHT WE HAVE THE LOW LEVEL JET RAMP UP EARLY THIS EVENING AS AN UPSTREAM SHORTWAVE...SEEN ON WATER VAPOR LOOPS... MOVES INTO THE AREA. THIS SYSTEM HAS DEEP UPPER SUPPORT WITH IT AND A JET SEGMENT TO HELP THE CAUSE. ALL OF THIS WILL WORK TOGETHER TO FINALLY PUSH THE WARM FRONT NORTH THROUGH THE CWA OVERNIGHT. THE FOCUS FOR CONVECTION WILL BE MORE WEST THEN EAST HOWEVER AS THAT IS WERE THE LOW LEVEL JET STAYS FOCUSED. THE MOST UNSTABLE CAPES RISE TO NEAR 4000 J/KG EARLY THIS EVENING SOUTH AND WEST OF GRAND RAPIDS BUT OVERNIGHT AS THE INSTABILITY SPREADS NORTH IT WEAKENS DRAMATICALLY. GIVEN PRECIPITABLE WATER VALUES ARE NEAR 2 INCHES... I SEE THIS MORE AS A HEAVY RAIN EVENT AS MOST OF THE STORMS WILL BE AFTER DARK OVER MOST OF THE AREA. TOMORROW THE TRAILING UPPER WAVE COMES THROUGH WITH A COLD FRONT. THAT BRINGS WESTERLY WINDS TO THE AREA AND SWEEPS THE INSTABILITY EASTWARD OVER TIME. SO I EXPECT THE CONVECTION TO WIDESPREAD EARLY IN THE DAY BUT TO BE MORE FOCUSED SOUTH AND EAST BY MID AFTERNOON. SUNDAY NIGHT MOST OF THE CONVECTION SHOULD BE SOUTH OF INTERSTATE 94 AS THAT IS WHERE THE FRONT STALLS ONCE AGAIN. THE UPSTREAM CANADIAN COLD FRONT COMES THROUGH MONDAY AFTERNOON. THAT WILL BRING A RENEWED THREAT FOR MORE THUNDERSTORMS BUT THE PROBLEM MONDAY IS THERE IS NO LOW LEVEL JET IN OUR AREA...EVEN WITH THE COLD FRONT COMING THROUGH. THE MOISTURE TRANSPORT VECTORS ARE NOT AIMED THIS WAY EITHER. SO THIS LOOKS LIKE ANOTHER TYPICAL SCATTERED STORMS WITH THE FRONT TYPE EVENT WITH A LOW RISK FOR SEVERE STORMS. I WOULD EXPECT CLEARING MONDAY NIGHT BEHIND THE COLD FRONT. .LONG TERM...(TUESDAY THROUGH SATURDAY) ISSUED AT 329 PM EDT SAT JUN 13 2015 NOT MUCH CHANGE IN THINKING THROUGH THE LONG TERM WITH MAINLY ZONAL FLOW FORECAST ALOFT. MAIN BAND OF THE WESTERLIES WILL BE POSITIONED OVER THE NORTHERN THIRD OF THE CONUS PLACING THE GREAT LAKES SQUARELY IN THE ZONE OF ACTION. A SURFACE FRONTAL BOUNDARY WILL BE NEARBY MUCH OF THE TIME...LOCATED PARALLEL TO THE UPPER FLOW WHICH INDICATES IT WILL BE LIKELY BE SLOW TO MOVE/ADVANCE OUT OF THE AREA. TIMING OF SHORTWAVES REMAIN PROBLEMATIC IS THIS FLOW REGIME. GFS AND THE ECMWF OPERATIONAL RUNS CONTINUE TO BE A BIT AT ODDS WITH ONE ANOTHER IN THE FURTHER OUT PERIODS...THURSDAY THROUGH SATURDAY. THE GFS TENDS TO DRIVE THE FRONT FURTHER SOUTH OF THE REGION DUE TO MORE AMPLIFIED UPPER FLOW. AT THIS POINT ITS TOO DIFFICULT TO REALLY LEAN ONE WAY OR ANOTHER AND HAVE OPTED TO CARRY CHANCES FOR PRECIP DEEP INTO THE WEEK. BEST CHANCES FOR SHOWERS/STORMS IN THE LONG TERM APPEARS TO BE WED/THURS AS A SHORTWAVE TROUGH RIPPLES THROUGH THE FLOW. BOTTOM LINE...NEAR NORMAL TEMPERATURES WILL PERIODS OF SHOWERS AND STORMS. WE WILL BE WATCHING THE END OF THE WEEK TOO SEE IF THE DRIER GFS OR THE WETTER ECMWF VERIFIES. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z SUNDAY AFTERNOON) ISSUED AT 212 PM EDT SAT JUN 13 2015 CEILINGS HAVE LIFTED SOME THIS MORNING AND EARLY AFTERNOON...FROM LIFR/IFR TO IFR/MVFR. CEILINGS GENERALLY RANGE FROM 500FT TO 1500FT ACROSS THE AREA. A PUSH OF CLEARING FROM THE SOUTH AND WEST IS TRYING TO NOSE IN...WITH SKIES CLEARING AT SOUTH HAVEN. FORECAST IS FOR A CONTINUED LIFTING OF THE CEILINGS THIS AFTERNOON AND EARLY EVENING AS THE CLEARING TRIES TO PUSH IN FROM THE SOUTH. BEST CHANCE OF SHOWERS AND STORMS WILL COME BETWEEN 00Z AND 06Z. SOME SHOWERS/STORMS CANNOT BE RULED OUT THIS AFTERNOON AND AGAIN OVERNIGHT EITHER. THINKING LOWER CEILINGS WILL DEVELOP ONCE AGAIN TONIGHT IN THE WAKE OF A WAVE OF PRECIPITATION LINGERING INTO THE MORNING OURS OF SUNDAY. && .MARINE... ISSUED AT 329 PM EDT SAT JUN 13 2015 THE ONLY SIGNIFICANT ISSUE FOR THE NEAR SHORE WILL BE THE FOG. WITH DEW POINTS RISING INTO THE LOWER 70S BY SUNDAY I WOULD EXPECT FOG TO OVERSPREAD THE NEAR SHORE WATERS. DRIER AIR REALLY DOES NOT COME IN UNTIL MONDAY. && .HYDROLOGY... ISSUED AT 128 PM EDT SAT JUN 13 2015 SHOWERS AND THUNDERSTORMS ARE EXPECTED AT TIMES INTO MID WEEK WITH AN INCH OR LESS OF PRECIPITATION. RIVER LEVELS ACROSS CENTRAL LOWER MICHIGAN ARE MOVING UP... BUT EXPECTED TO REMAIN BELOW BANKFULL. RIVERS WILL RUN HIGHER THAN NORMAL HEADING INTO NEXT WEEK. THE SOUTH OF MICHIGAN HAS NOT RECEIVED AS MUCH RAIN AND RIVER LEVELS REMAIN STEADY. && .GRR WATCHES/WARNINGS/ADVISORIES... MI...NONE.
