The Automated Weather Observation System (AWOS) instruments at the airport in Wayne were hit by the tornado on October 4th and severely damaged. The Wayne observation will be offline indefinitely while new equipment is ordered and installed. This process will take at least several weeks and could take several months to complete.
The Wayne AWOS stopped reporting data at 5:15 PM on October 4th, which is just before the tornado struck the site. Meteorologists are interested in data from the observation site, because direct observations of tornadoes by weather instruments are rare. Direct strikes of tornadoes on weather instruments are rare because tornadoes are relatively small, and observation sites also are small and widely scattered, so getting a tornado to pass directly over an observation site requires quite a bit of "luck". Also, once the instruments are directly struck by a tornado, they are usually damaged and stop recording data. In this case, the debris from the AWOS station is so widely scattered that data recovery is not likely, as most of the pieces have not yet been found.
