DUKEWhat forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Grand Rapids, MI wrote its last area forecast discussion before this severe thunderstorm warning went out at Apr 11, 12:30 PM EDT, 14 minutes earlier.
Area forecast discussion, Apr 11, 12:30 PM EDT, 14 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 1230 PM EDT FRI APR 11 2008 LATEST UPDATE...SHORT TERM... .SYNOPSIS...(423 AM EDT FRI APR 11 2008) A WARM FRONT WILL LIFT UP TO THE INTERSTATE 96 CORRIDOR TODAY...ALLOWING MUCH WARMER AIR TO MOVE IN OVER THE SOUTHERN PORTION OF THE AREA. THUNDERSTORMS ARE EXPECTED TO DEVELOP LATE THIS MORNING AND EARLY THIS AFTERNOON AS A COLD FRONT MOVES THROUGH THE AREA. SOME OF THE THUNDERSTORMS COULD BECOME SEVERE. COLDER AIR WILL MOVE IN BEGINNING TONIGHT...AND SHOWERS WILL CONTINUE ACROSS THE AREA THROUGH SATURDAY NIGHT. SOME SNOW IS EXPECTED TO MIX IN LATE SATURDAY...AND CHANGE OVER TO ALL LIGHT SNOW SATURDAY NIGHT. MILDER AND DRIER AIR WILL GRADUALLY BUILD IN EARLY NEXT WEEK. && .SHORT TERM...(423 AM EDT FRI APR 11 2008) (TODAY THROUGH SUNDAY) WARM FRONT HAS MADE IT NORTH TO THE I-96 CORRIDOR AS OF NOON AND A TRIPLE POINT IS EVIDENT NEAR MILWAUKEE. COLD FRONT EXTENDS SSE FROM THERE. SFC LI/S HAVE DROPPED TO -5 OR SO OVER THE SW CORNER OF LWR MI AND THAT INSTABILITY WILL SPREAD FARTHER NORTH AND EAST OVER THE NEXT FEW HOURS. EVERYTHING LOOKS ON TRACK FOR SOME SVR WEATHER TODAY CONSIDERING THE CLEARING SOUTH OF THE WARM FRONT. TORNADO WATCH WILL LIKELY BE ISSUED BY 18Z PER SPC AND WILL UPDATE GRIDS/ZONES AT THAT TIME. THE FOCUS IS ON THE SEVERE WEATHER THREAT ACROSS THE CWFA THIS AFTERNOON. INDICATIONS REMAIN THAT THE DEVELOPING TRIPLE POINT WILL MOVE ABOUT AS FAR NORTH AS M-46...ALLOWING THE SRN HALF OF THE CWFA TO SNEAK INTO THE WARM SECTOR. TEMPS SHOULD WARM WELL INTO THE 60S AND APPROACH 70 DOWN SOUTH. THIS WILL OCCUR AS THE COLD POOL ALOFT WILL MOVE IN WITH STEEP MID LEVEL LAPSE RATES APPROACHING 8.0 C/KM CENTERED AROUND 18Z. MODELS INDICATE ML CAPES OF 500-1000 J/KG WILL DEVELOP AND SFC BASED LI/S WILL DROP DOWN TO AROUND -5 TO -6 BY 18Z...ESPECIALLY FURTHER SOUTHEAST. CONVECTION IS EXPECTED TO FIRE OVER THE CWFA...AND WILL LIKELY EXIT THE CWFA AROUND OR JUST AFTER 21Z. WIND PROFILES IN THE WARM SECTOR WILL BE GENERALLY UNIDIRECTIONAL WHICH WOULD SUPPORT BOWING LINES. LARGE HAIL WILL BE POSSIBLE WITH ANY OF THE STORMS DUE TO THE STEEP MID LEVEL LAPSE RATES MENTIONED ABOVE. TORNADOES WILL ALSO BE POSSIBLE WITH 20-30 KNOTS OF 0-1KM SHEAR...0-1KM HELICITIES OVER 100 M2/S2...AND THE TRIPLE POINT IN THE VICINITY. AREAS IN THE VICINITY OF THE WARM FRONT WILL ALSO BE UNDER A TORNADO POTENTIAL. THE THING THAT COULD LIMIT THIS ALL IS IF SUNSHINE ENDS UP BEING LIMITED. THIS SITUATION DEFINITELY HAS TO BE MONITORED. ONCE FRONT MOVES THROUGH...COLDER AIR ADVECTS IN AROUND THE SRN PORTION OF THE OCCLUDING LOW. A FEW SHOWERS WILL BE POSSIBLE TONIGHT...BUT THE BEST POTENTIAL OF PCPN WILL BE NORTH OF THE LOW WHERE THE WRAP AROUND MOISTURE/TROWAL WILL BE FOUND. THIS PCPN WILL THEN SHIFT SOUTH THROUGH THE DAY ON SAT...ALLOWING MOST AREAS TO SEE PCPN. P-TYPE LOOKS TO BE MAINLY RAIN THROUGH 00Z SUN WITH ENOUGH WARM AIR AT THE SFC...WITH PCPN CHANGING OVER THE SNOW FROM N TO S AS THE COLDER AIR MOVES IN. SOME LOCATIONS COULD SEE A DUSTING OF SNOW BEFORE THE MAJORITY OF THE PCPN ENDS SAT NIGHT. A RESIDUAL CHC OF RAIN OR SNOW SHOWERS REMAIN ON SUN AS THE GENERAL UPPER FLOW REMAINS CYCLONIC. && .LONG TERM...(423 AM EDT FRI APR 11 2008) (SUNDAY NIGHT THROUGH THURSDAY) HIGH PRESSURE SETTLES IN ON THE REGION SUNDAY NIGHT INTO TUESDAY PROVIDING MAINLY DRY AND COOLER THAN NORMAL WEATHER. SOUTHWEST WINDS STRENGTHEN LATER TUESDAY INTO WEDNESDAY AS THE HIGH PUSHES EAST OF THE REGION. THIS WILL ALLOW FOR A WARM UP. PRECIPITATION CHANCE REMAIN LOW GOING INTO WEDNESDAY AND THURSDAY. A WEAKENING COLD FRONT WILL BE CROSSING THE AREA FOR THE END OF THE WEEK. && .AVIATION...(745 AM EDT FRI APR 11 2008) WILL NEED TO MONITOR THE DEVELOPING FOG NEAR KSBN AND KJXN. AS THE WARM FRONT LIFTS NORTH...IFR OR LOWER CONDITIONS HAVE BEEN FORECASTED FOR ALL TAF SITES FOR A FEW HOURS THIS AM. THEN THE COLD FRONT COMES THROUGH THIS AFTERNOON. I FEATURED A HIGHER THUNDERSTORM THREAT THE FURTHER EAST...FOR KLAN AND KJXN. BEHIND THE COLD FRONT CEILINGS WILL FALL TO MVFR OVERNIGHT. && .MARINE...(423 AM EDT FRI APR 11 2008) WINDS ARE NOW COMING DOWN ALONG THE LAKESHORE AS THE CORE OF THE LOW LEVEL JET IS MOVING EAST OF THE AREA. THE EASTERLY COMPONENT TO THE WIND HAS LIMITED WAVE HEIGHT. WINDS WILL BECOME MORE SOUTHWEST LATER TODAY WITH THE APPROACH AND PASSAGE OF THE FRONT. WINDS ARE EXPECTED TO SPIKE UP ONCE AGAIN NEAR THE FRONT. IT LOOKS LIKE A SMALL CRAFT ADVISORY SHOULD COVER THIS MORNING AND THIS AFTERNOON. WINDS WILL BECOME NORTHERLY ON SUNDAY AS THE OCCLUDED LOW SHIFTS SOUTH OF THE AREA. && .HYDROLOGY...(423 AM EDT FRI APR 11 2008) THE AREAL FLOOD WATCH WAS CANCELLED THIS MORNING AS ALL OF THE HEAVIER RAIN HAS SHIFTED EAST OF THE CWFA. ADDITIONAL RAINFALL IS LIKELY THIS AFTERNOON WITH CONVECTION THAT DEVELOPS ALONG THE FRONT...HOWEVER ADDITIONAL BASIN QPF SHOULD REMAIN BELOW A QUARTER OF AN INCH. RAINFALL AMOUNTS ACROSS THE AREA HAVE RANGED FROM HALF AN INCH UP TO TWO INCHES AT SOME LOCATIONS. RAINFALL HAS BEEN PRETTY MUCH IN LINE WITH WHAT WAS EXPECTED YESTERDAY...AND WHAT WAS INPUT INTO THE HYDROLOGIC MODELS AT THE RFC. WE EXPECT WHEN THE NEW FORECAST COME OUT LATER THIS MORNING...MANY RIVERS WILL BE FORECAST TO RISE ABOVE ACTION STAGE...BUT WILL LIKELY END UP JUST SHORT OF FLOOD STAGE AT MOST LOCATIONS. && .GRR WATCHES/WARNINGS/ADVISORIES...
