What forecasters said that day
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

Area forecast discussion, May 26, 2:10 AM EST, 3 hours 50 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 310 AM EDT SAT MAY 26 2001 DISC: UPPER LVL LOW OVER THE GREAT LAKES REGION FORECAST TO STAY PUT THROUGH MOST OF THE HOLIDAY WEEKEND WITH VORT MAX/S MOVING ACROSS THE CWA WITH THE GENERAL FLOW. AS A RESULT...CLOUDY SKIES WILL BE THE RULE FOR A LOT OF THE TIME. HOWEVER SUNSHINE IS POSSIBLE ESPECIALLY ON SUN AND THE WEEKEND WON/T BE A TOTAL WASHOUT SINCE PRECIPITATION WON/T BE FALLING ALL THE TIME. THUNDERSTORMS ARE POSSIBLE TODAY AND SUN...BUT MOST PARAMETERS ARE NOT SHOWING CONDITIONS TOO FAVORABLE FOR SEVERE WEATHER. HAVE GONE WITH LIKELY POPS IN MOST LOCATIONS TODAY AND TONIGHT...WITH CHANCE POPS ON SUN...MAINLY LATER IN THE DAY OR IN THE EVENING HOURS. FLOODING CANNOT BE RULED OUT BUT WILL BE MORE ISOLATED THAN WIDESPREAD IF IT DEVELOPS. SHOWERS AND THUNDERSTORMS STILL POSSIBLE ON MON BUT THERE COULD ALSO BE A FEW PEAKS OF SUN THROUGH THE CLOUDS SO HAVE GONE WITH LESS PESSIMISTIC WORDING BY USING VARIABLE CLOUDINESS RATHER THAN MOSTLY CLOUDY IN THE FIRST DAY OF THE EXTENDED. DID NOT STRAY TOO FAR FROM MOS TEMP GUIDANCE IN THIS PACKAGE. NO MAJOR CHANGES TO THE EXTENDED FIN THIS PACKAGE. NOTHING ON THE MARINE AT THE CURRENT TIME...AND NOT EXPECTING ANYTHING IN THE NEAR FUTURE. .PHI...NONE. JJM
