[Mpls] Air pollution advisory is current

[mclemore at bitstream.net]

My apologies:  Becky Helgeson (who sends out these advisories) 
inadvertently posted an incorrect date, and I'm afraid I neglected to 
correct it before I sent out the missive.  Mea culpa.  

But the information is indeed current, not a month old.
