What 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 Jun 27, 7:30 PM EDT, 1 hour 50 minutes earlier.

Area forecast discussion, Jun 27, 7:30 PM EDT, 1 hour 50 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
730 PM EDT FRI JUN 27 2008

LATEST UPDATE...AVIATION...

.SYNOPSIS...(320 PM EDT FRI JUN 27 2008)
A LARGE UPPER LOW IN THE DAKOTAS WILL SLOWLY MOVE TOWARD THE REGION.
SHOWERS AND THUNDERSTORMS... SOME POSSIBLY STRONG TO SEVERE ARE
EXPECTED EARLY THIS EVENING THROUGH SATURDAY. HEAVY RAINFALL IS ALSO
POSSIBLE. WARM AND HUMID CONDITIONS ARE EXPECTED THIS AFTERNOON INTO
TOMORROW EVENING WITH COOLER CONDITIONS FOR THE END OF THE WEEKEND
AND BEGINNING OF NEXT WEEK. ANOTHER SYSTEM WILL THEN LAY A FRONT
ACROSS THE REGION PROVIDING A FOCUS FOR SHOWERS AND THUNDERSTORMS
WEDNESDAY THROUGH FRIDAY.

&&

.SHORT TERM...(320 PM EDT FRI JUN 27 2008)
(TONIGHT THROUGH MONDAY)
FORECAST CONCERNS ARE THE SEVERE THREAT THROUGH SATURDAY AND HEAVY
RAIN POTENTIAL.

THE BASIC SCENARIO HAS A STRONG UPPER LOW MOVING FROM THE PLAINS TO
NORTH OF LAKE HURON BY SUNDAY NIGHT. SEVERAL SHORT WAVES ARE
FORECAST TO EJECT FROM THE LOW AND MOVE ACROSS THE STATE. THIS WILL
CREATE SEVERAL OPPORTUNITIES FOR STORMS TO DEVELOP. PRECIPITABLE
WATER VALUES FROM 1.5 TO 2.0 INCHES WILL ALLOW FOR HEAVY RAINFALL
WITH ANY THUNDERSTORMS THAT FORM TONIGHT THROUGH TOMORROW. HIGHER
SHEAR VALUES WILL MOVE INTO THE AREA SATURDAY AHEAD OF A COLD FRONT.
THE MODEL TRENDS HAVE BEEN FOR SLOWER PROPOGATION WITH THE MAIN LOW.
A COLD FRONT IS NOW FORECAST TO MOVE THROUGH THE AREA SATURDAY
AFTERNOON OR EARLY EVENING. THE GREATEST CHANCE OF SEVERE WEATHER
WILL LIKELY BE AWAY FROM LAKE MICHIGAN SATURDAY AFTERNOON AND
EVENING AS THE COLD FRONT COLLIDES WITH VERY WARM AND MOIST AIR OVER
THE REGION. A 50-60KT MID LEVEL JET WILL CREATE AN ENVIRONMENT
CONDUCIVE FOR BOWING LINE SEGMENTS SATURDAY.

COOLER WX IS EXPECTED SUNDAY WHEN THE UPPER LOW MOVES OVER THE
REGION. HIGH TEMPERATURES SUNDAY ARE EXPECTED TO ONLY BE AROUND 70
DEGREES. EXPECT TO SEE ONLY LIGHT SHOWERS WITH A VERY SLIGHT CHANCE
OF THUNDER SUNDAY ENDING MONDAY.

&&

.LONG TERM...(320 PM EDT FRI JUN 27 2008)
(MONDAY NIGHT THROUGH FRIDAY)
GOING GRIDS AND FORECAST ONTRACK GIVEN THE MID RANGE MODEL
DIFFERENCES WEDNESDAY THROUGH FRIDAY. HAVE PUT SHOWERS AND
THUNDERSTORMS IN FOR FRIDAY ESPECIALLY WITH THE UNCERTAINTY IN
TIMING LATE IN THE FORECAST. SEE THE PREVIOUS DISCUSSION BELOW FOR
THE REST OF THE LONG TERM PERIODS.

THE TREND IS FOR A SLOWER DEPARTURE OF THE UPPER LOW EARLY NEXT
WEEK. THE MAIN CHANGE AS A RESULT IS FOR SOMEWHAT LOWER TEMPERATURES
MON INTO TUE. EARLY ON THERE IS DECENT AGREEMENT AMONGST THE MEDIUM
RANGE MODELS IN SLOWLY TRACKING THE UPPER LOW EAST OF THE GREAT
LAKES REGION MONDAY INTO TUESDAY. ON MONDAY THERE COULD BE SCATTERED
SHOWERS AND PERHAPS A THUNDERSTORM. HOWEVER... RIDGING WILL BE
BUILDING IN FOR TUESDAY AND THAT SHOULD LEAD TO DRY WEATHER. GOING
INTO WEDNESDAY... THE WEATHER BECOMES LESS CERTAIN. THE ECMWF IS
TRACKING A STRONGER SHORTWAVE IN FROM CENTRAL CANADA. IF THIS
HAPPENS... SOME THUNDERSTORMS COULD ARRIVE FOR WED AS A COLD FRONT
PUSHES THROUGH. THE GFS SHOWS A MUCH WEAKER WAVE ON WEDNESDAY...
WITH STRONG RIDGING FOR THURSDAY ALONG WITH BUILDING HEAT. THE
CANADIAN GLOBAL SUPPORTS THE ECMWF SCENARIO AND I WILL LEAN AWAY
FROM THE GFS FOR WED. THEREFORE I ADDED A LOW POP TO THE FORECAST
FOR WEDNESDAY... MAINLY ACROSS THE NORTH.

&&

.MARINE...(320 PM EDT FRI JUN 27 2008)
OUTSIDE OF THUNDERSTORMS THERE ARE NO MARINE CONCERNS THROUGH THE
FORECAST PERIOD. SOUTH WINDS WILL INCREASE A LITTLE TONIGHT AND
SWING TO THE SOUTHWEST OVERNIGHT. WINDS AND WAVES ARE EXPECTED TO
REMAIN BELOW SCA CRITERIA.

&&

.AVIATION...(730 PM EDT FRI JUN 27 2008)
THE WEAKENING COLD FRONT WILL CONTINUE TO TRIGGER DEVELOPMENT OF
SCATTERED SHOWERS AND THUNDERSTORMS THROUGH THE EARLY MORNING HOURS
AT ALL TAF SITES. THERE IS SOME POTENTIAL FOR HAIL AND CONVECTIVE
WIND SHEAR WITH THESE STORMS IN ADDITION TO BRIEF HEAVY RAIN AND
OCCASIONAL LIGHTNING. WE CONTINUE TO ANTICIPATE WIDELY SCATTERED
MVFR/IFR CIGS/VISBYS WITH FOG AFTER MIDNIGHT. FOG SHOULD BURN OFF BY
MID MORNING ON SAT.

&&

.HYDROLOGY...(320 PM EDT FRI JUN 27 2008)
THERE IS THE POTENTIAL FOR HEAVY RAIN TONIGHT INTO TOMORROW WITH
HIGH PRECIPITABLE WATER VALUES RANGING FROM 1.5 TO 2 INCHES.
LOCALIZED FLOODING WILL BE POSSIBLE WITH MANY OF THE STORMS THAT
DEVELOP. THE HEAVY RAIN COULD PUSH AREA RIVERS/STREAMS TO BANKFULL.

&&

.GRR WATCHES/WARNINGS/ADVISORIES...
