I also checked the AWS obs in the area. There WAS a station in La Plata,
which is no longer reporting. The
next nearest 2 stations, 1.7 and 4.2 miles away, did not report on
4/28. I'll write AWS and see if they have any information.

>The APRSWXNET/Citizen Weather Observer Program (CWOP) is a group of
>interested amateur radio operators and citizen observers, organized by
>FSL, who contribute real-time weather data via packet radio and the
>internet for use in NOAA activities. This volunteer program had a recent
>notable success. On April 28, 2002, atmospheric conditions in close
>proximity to the first documented "F5" tornado in the state of Maryland
>were measured and observed by three members of the CWOP program. Greg
>Jones (K3GJ) was up and reporting prior to and during the tornado that
>struck La Plata, MD. He was able to record a 125-mph wind gust before he
>lost power. Just upstream in Potomac Heights, MD, another CWOP member,
>Joe Sartori (WB3IUT) was also "live" during the event. Joe received
>3-inch hail but not the direct hit of the winds.

>Greg and Joe's stations are the only routinely reporting weather data
>available in Charles County (the closest METAR station is 19 miles north
>at Andrews AFB). Their storm reports have been forwarded to the local NWS
>Weather Forecast Office in Sterling, VA. Further down stream in
>Mechanicsville, Northern St Mary's County, MD, JD Delany (WX3SMD) was also
>on-line and reporting prior to and during the event. He observed an
>estimated gust to 40 mph as the tornadic storm roared by to the north of
>his location. All three APRSWXNET/CWOP members provided valuable
>information during this historic tornadic event and should be commended
>for their efforts.
