My bike commuting mileage is way off this summer because we've had an incredible frequency of thunderstorms, most of them with lots of lightning and heavy rains. Last time I checked, our YTD rainfall was about 10" above normal, most of that coming in summer. Deciding whether to ride each day is like playing Russian roulette because the forecasts have called for a 30-60% chance of storms nearly every day. It has stormed somewhere in the area nearly every day, but the exact locations and times are unpredictable. Most of the time, I can avoid the storms by diligently watching the radar and timing my departure from work so I leave before or after they hit. However, on some days the storms develop extremely rapidly and I've been caught on my afternoon commute even though nothing was showing on the radar when I left work. I will be SO glad when the fall weather finally arrives.
