Weather patterns
It's amazing how periodic and regular weather patterns can be sometimes. I was looking over my ride calendar yesterday, and I've missed riding every Monday and Thursday for the past 4 weeks due to storm systems rolling through our area. It's been like clockwork. I was hoping the pattern would break this week and I could bike commute 4-5 days, but the same old thing has happened again. Monday it rained pretty much all day, particularly hard during the morning and afternoon rush hours. Today it is clear in the morning, but a strong line of severe storms is supposed to pass through the area this afternoon with heavy rain, hail and high winds.
At least we haven't been in one of those patterns where it rains every weekend, which happens from time to time. We actually have had pretty nice weather on the weekends lately, for the most part, but Mondays and Thursdays you better watch out.
