NWS Grand Rapids, MI wrote its last area forecast discussion before the first event at Aug 25, 1:12 PM EST, 28 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 212 PM EDT MON AUG 25 2014 LATEST UPDATE... MESOSCALE DISCUSSION .MESOSCALE DISCUSSION... ISSUED AT 147 PM EDT MON AUG 25 2014 LIMITED SEVERE/FLOODING THREAT CONTINUES THIS AFTERNOON. ONLY PEA SIZED HAIL AND WINDS AROUND 35 MPH REPORTED SO FAR WITH THESE STORMS. A BROKEN LINE OF STORMS IS EXTENDING FROM CHICAGO TO EAST OF GRAND RAPIDS AT 2 PM. NEW UPDRAFTS ARE CURRENTLY GOING UP ALONG THE OUTFLOW BOUNDARIES SINKING SOUTH OF THE STORMS NEAR GRAND RAPIDS AND THESE STORMS SHOULD REACH CHARLOTTE AND LANSING BY 4 PM. THE STORMS OVER SOUTHERN LAKE MICHIGAN ARE MOVING EAST SOUTHEAST AND RADAR TRENDS SUGGEST THE HEAVIER STORMS WILL PASS TO THE SOUTH OF THE I-94 CORRIDOR. TEMPS ARE IN THE MID TO UPPER 80S THERE AND SFC HEATING COMBINED WITH SFC DEW POINTS IN THE 70S HAVE RESULTED IN STRONG INSTABILITY AND STORMS MAY EXPAND INTO THIS AREA BY LATE AFTERNOON OR EARLY EVENING. && .SYNOPSIS... ISSUED AT 325 AM EDT MON AUG 25 2014 WARM AND HUMID CONDITIONS WILL CONTINUE TODAY THROUGH TUESDAY WITH SCATTERED SHOWERS AND THUNDERSTORMS. THUNDERSTORMS THIS AFTERNOON THROUGH TUESDAY MAY CONTAIN LOCALLY HEAVY RAINFALL. DRY AND COOLER WEATHER WILL BRIEFLY RETURN WEDNESDAY FOLLOWED BY WARMER AND MORE HUMID WEATHER WITH ANOTHER CHANCE OF SHOWERS AND STORMS LATE IN THE WEEK. && .SHORT TERM...(TODAY THROUGH WEDNESDAY) ISSUED AT 325 AM EDT MON AUG 25 2014 IT WILL BE VERY WARM AND HUMID TODAY WITH MAX TEMPS REACHING WELL INTO THE 80S AND DEW POINT VALUES UP INTO THE UPPER 60S TO LOWER 70S. SCATTERED SHOWERS AND THUNDERSTORMS WILL DEVELOP LATER TODAY AS INSTABILITY BUILDS AND SB CAPE VALUES POTENTIALLY REACH AROUND 2000-2500 J/KG NEAR TO EAST OF US-131 THIS AFTERNOON. SEVERE WX IS UNLIKELY MAINLY DUE TO WEAK DEEP LAYER SHEAR BUT AN ISOLATED SEVERE STORM CANNOT BE RULED OUT THIS AFTERNOON AND EARLY EVENING WHEN INSTABILITY WILL BE MAXIMIZED. ANY STORMS THAT DO DEVELOP COULD PRODUCE LOCALLY RAINFALL WITH PRECIPITABLE WATER VALUES UP IN THE 1.75 TO 2 INCH RANGE TODAY. SCATTERED SHOWERS AND PERHAPS A FEW STORMS WILL CONTINUE INTO THIS EVENING. THEN THE COLD FRONT WILL BRING SCATTERED SHOWERS AND THUNDERSTORMS ON TUESDAY. THE BEST CHANCE FOR A FEW STRONG TO POTENTIALLY SEVERE STORMS TUESDAY WOULD BE IN THE AFTERNOON OVER OUR SE FCST AREA WHEN SB CAPE VALUES WILL POTENTIALLY REACH AROUND 3000 J/KG. IT HAS BEEN NOTED THAT OVERALL SHORT TO MEDIUM RANGE GUIDANCE TRENDS ARE BRINGING THE COLD FRONT THROUGH FASTER. THEREFORE WE HAVE TRIMMED BACK POPS SIGNIFICANTLY FOR TUESDAY NIGHT AND ARE KEEPING LINGERING LOW POPS CONFINED TO OUR SOUTHERN FORECAST AREA. DRY WEATHER IS NOW ANTICIPATED WEDNESDAY WITH THE HIGH PRESSURE RIDGE IN PLACE OVER THE NORTHERN GREAT LAKES REGION. .LONG TERM...(WEDNESDAY NIGHT THROUGH SUNDAY) ISSUED AT 325 AM EDT MON AUG 25 2014 THE LAST COUPLE NIGHTS HAVE SEEN THE GFS GUIDANCE TREND TOWARDS THE ECMWF IN TERMS OF THE EVOLUTION OF THE PATTERN. TONIGHT...HAVE THEREFORE FOLLOWED THE LEAD OF THE ECMWF THROUGH THE LONG TERM FORECAST. THE LONG TERM LOOKS TO FEATURE A DECENT ABOUT OF RAINFALL WITH A BOUNDARY OSCILLATING THROUGH THE REGION AND NEAR NORMAL TEMPERATURES. AS FOR THE DETAILS...THE PERIOD LOOKS TO START OFF DRY WITH SURFACE HIGH PRESSURE SAGGING INTO THE AREA FROM THE NORTH WEDNESDAY NIGHT. FEEL THURSDAY WILL LIKELY BE DRY AS WELL...BUT BLENDED IN WITH NEIGHBORING OFFICES AND HAVE A 20 PCT CHANCE FOR SHOWERS/STORMS IN THE FAR WEST. CHANCES FOR SHOWERS AND STORMS THEN LOOK TO BE POSSIBLE IN THE REMAINDER OF THE FORECAST PERIOD...THURSDAY NIGHT THROUGH SUNDAY. MOISTURE COMES SURGING BACK IN THURSDAY NIGHT ESPECIALLY ALOFT. THE ECMWF HAS A WARM FRONT OR A STATIONARY BOUNDARY NEARBY FRI-SUN. HAVE CHANCE POPS ESSENTIALLY BLANKETED THROUGHOUT THIS PERIOD OF THE FORECAST. THE DAYS 4-5 AND 6-7 QPF PROGS FROM WPC ALSO BEAR THIS OUT. THEY SHOW RAINFALL TOTALS AROUND AN INCH FOR MOST AREAS...WHICH SEEMS REASONABLE. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z TUESDAY AFTERNOON) ISSUED AT 139 PM EDT MON AUG 25 2014 A STORMY AFTERNOON IS EXPECTED AS A BROKEN LINE OF TSRA SLOWLY DROPS SOUTHEAST ACROSS THE TAF SITES. GIVEN THE HIGH MOISTURE CONTENT OF THE STORMS...HEAVY RAIN WILL LIMIT VSBYS TO 2SM. IT'S POSSIBLE VSBYS COULD FALL TO A MILE. PCPN WILL DIMINISH THIS AFTERNOON BUT POTENTIALLY REDEVELOP TUESDAY MORNING AS A COLD FRONT MOVES THROUGH. MVFR FOG WILL LIKELY DEVELOP AFTER 06Z. && .MARINE... ISSUED AT 325 AM EDT MON AUG 25 2014 MINIMAL WIND AND WAVE ACTION IS ANTICIPATED TODAY THROUGH TONIGHT INTO TUESDAY. HOWEVER PATCHY FOG WILL POSE A HAZARD TO MARINERS. && .HYDROLOGY... ISSUED AT 1104 AM EDT SUN AUG 24 2014 BEST CHANCE FOR SIGNIFICANT RAINFALL WOULD BE MONDAY NIGHT THROUGH WEDNESDAY WITH A SLOW MOVING COLD FRONT. THIS IS NOT A GUARANTEE AS THE LLJ IS FORECAST TO BE QUITE WEAK. NEVERTHELESS...A VERY MOIST ATMOSPHERE COMBINED WITH FORCING VIA THE COLD FRONT AND SLOW CELL MOVEMENT COULD RESULT IN SOME SIGNIFICANT RAINFALL IF STORMS DEVELOP OVER OUR AREA. PW VALUES WILL LIKELY BE AROUND 1.75" MONDAY NIGHT AND TUESDAY. MODEL GUIDANCE IS MIXED REGARDING HOW LONG THE FRONT MAY HANG UP...SO IT IS UNCLEAR WHEN THE THREAT FOR SIGNIFICANT RAINFALL WOULD END. && .GRR WATCHES/WARNINGS/ADVISORIES... MI...NONE.
