Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
The episode as NWS CTP wrote it up.
Cyclonic flow aloft prevailed over the Northeast states on southern fringe of nearly stationary upper low centered over eastern Hudson Bay. Shortwave impulses rotating around the southeast flank of the low maintained a seasonably strong 700-500mb west-southwest flow. The combination of strong heating, high moisture content (PW) and moderately steep lapse rates contributed to the development of severe storms.
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.
NWS State College, PA wrote its last area forecast discussion before the first event at Jul 2, 10:25 AM EST, 1 hour 5 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 1125 AM EDT WED JUL 2 2014 .SYNOPSIS... SCATTERED THUNDERSTORMS WILL POSE A THREAT FOR DAMAGING WIND GUSTS AND HAIL THIS AFTERNOON AND EVENING. THE INTERACTION OF A SLOW MOVING COLD FRONTAL BOUNDARY AND ARTHUR WILL SUPPORT MORE SHOWERS AND THUNDERSTORMS ON THURSDAY...WITH HEAVY RAIN POSSIBLE MAINLY OVER EASTERN PORTIONS OF THE KEYSTONE STATE. HOWEVER...MUCH OF THE REGION WILL NOT BE IMPACTED BY ARTHUR AS IT TRACKS FAR ENOUGH OFF THE EASTERN SEABOARD. HIGH PRESSURE ACCOMPANIED BY COOLER AND LESS HUMID CONDITIONS WILL BRING A VERY COMFORTABLE AND DRY 4TH OF JULY HOLIDAY WEEKEND. && .NEAR TERM /UNTIL 1 PM THIS AFTERNOON/...

MORE NUMEROUS TSTMS CAN BE EXPECTED IN THE AFTERNOON AS A SHORTWAVE SLIDES THROUGH...PROVIDING ADDITIONAL LIFT TO AN ALREADY UNSTABLE AIRMASS.
