Ahhh, I finally found a wind sensor that shows the wind near MM19 on Saturday.
See that day's history here:

The link for the current conditions there would be:
http://www.wunderground.com/weatherstation/WXDailyHistory.asp?ID=KUTSARAT6I've taken the liberty of adding this link to the MM19 description on the google map. I'll try to keep an eye on it to see if it accurately reflects onsite reports (hopefully my own onsite observation will be part of that!)
Strange though how none of the other sensors (Olympic Park, Lehi HS, Provo) really show much at that time. Is it really that localized? Or are the other sensors just in bad locations? Seems like a big body of water like that would be a nice place for wind to blow. I suppose maybe it just spreads out over the great expanse of it. These are mostly rhetorical questions, but if anybody has any insight, I'd love to hear it.
