Choose "Preliminary Climate Report" and Archived Data. Then a month. Column 16 makes a note for thunder with the number 3. There's less than you'd expected. Either the station doesn't carefully record every one or there's a high threshold for thunder (maybe has to be particularly close?). I don't think the weather station records more info on thunderstorms than that.
central park observation is from an ASOS. And there is a threshold in how close lightning is observed for when T is then carried in the observation. Sometimes too, some ASOS's may have maintenance issues and have a TSNO on the obs....thunderstorm info not available. During the winter time....there is staff (I dont recall whom) do snow meaurements...these are snow paid observers. Paid to record snow every 6 hours and snow depth.

I've always wondered about that, actually. How close exactly does lightning have to be for it to be recorded as a thunderstorm?

Here is some info in regards to the ALDARS system used now for lightning/thunderstorm detection. ASOS will report TS if it detects lightning within 5 miles of the airport. Use VCTS within 5-10 miles of the airport. If there is an observer augmenting the data, they can change what ASOS gives them. I specifically dont know about the augmention of the central park ASOS site...I know must be a paid observer for snowfall. But I could be wrong.
