By the time Seattle and L.A. kickoff at the CLink, temperatures will drop to freezing, with a wind chill driving it down to feel like the mid-20s. Better bring an extra scarf or two, if not for yourself then for those in need of winter wear.
To date, the coldest first kick on record, both home and away, is 39 degrees. That was the temp for consecutive matches early in the inaugural season: a 2:0 win over RSL and an identical result at Toronto in the inaugural road test a week later.
By the way, there have been 12 Sounders home and three road matches starting in sub-50 temperatures. Seattle is 10-3-2 in those games.
