Jeff,

You are forgetting that LaGaurdia uses glide slope wind profilers to profile
wind velocity in a conical scan around the entire airport. Their profilers
reach all the way to the Connecticut shore and the data is very often used
by knowledgeable sailboat racers to win races, especially in the vicinity of
City Island. The data is good from the water surface up to several thousand
feet. You won't find the data on any NOAA site, it is available from FAA
sites. The data does show continuous gusts of very warm air, highly
localized, emanting from a sailboat near City Island. Divergence
calculations of the flow showed lack of continuity in the flow, it was
obviously a source of wind generation. The FAA labelled it a "Bloviation
Anamoly".
