Well, we have our "Monsoon" season, June and July, when it rains pretty heavily and often. In winter we have occasional freezing rain. And yes, it's true that one year we had to scrape ice off the asphalt circles during the Southwest Regionals.
Then of course there was the infamous 10th Annual VSC, which was cut short by freezing temp's, rain and wind. We spent most of that weekend sitting inside a local IHOP. Mighty unusual, that one. Normally it's quite warm, or at least pleasant, during the VSC.
All of this is pretty much forgotten by June thru August...when it's possible to fry an egg on the sidewalk.
