This isn't to pick on you.  I've seen this a bunch of times lately and many times today.  Do these wx stations use a different formula to calculate heat index than wpc or the nws use?

Not really sure...I think that the pws seem to record higher dews, so that's the difference in the heat index values....Grain of salt.

Type your current temp and dp into the calculator and you'll see what I mean.
