Another indication of the pain coming, Minneapolis set their all-time dew point record today (82). It is likely that the state record fell too (88 in Madison, MN yesterday).

where do these statistics come from? NCDC doesnt keep them from what i know. are they all unofficial?

I've been on an e-mail chain with Steve Zubrick from LWX.. I think Jason is going to do a post on this in the next few days. Steve pointed to July 16, 1980 4pm Ob
