Hey guys, I've noticed it before. But tonight I was flying down to Tampa from Chicago Midway. Flightplan loaded and perfect weather out of KMDW. But Altimeter settings kept bouncing up and down. So I started keeping track of a few reporting stations. KDNW - 29.92 KPNQ 29.92 KLWV 29.73 These are consective stations that AS2004 is reporting. Something is not right with these. There can not be that much difference between stations.

I couldn't check, but is this possible with all the rain/snow/crap we have in the Midwest? Can you keep a look out for us?JimActiveSky Support

Just throwing this out there - was the flight plan that you loaded supposed to be flown at an altitude over 18,000' and PNQ and DNW were prior to top of descent while LWV was after?
