I've used the
Weather Underground web site for many years. One of their more recent features is called the
WunderMap and I've found that it can be quite useful as a "pre-ride" weather source when you're wondering just how many layers you may be piling on in order to stay warm. In addition to superimposing weather radar over neighborhood level maps, it displays detailed weather information from multiple weather reporting points.
I'm making an assumption here, of course, that most bicycle commuters - like pilots - check the weather before they head out from a safety and preparedness standpoint.
If that's true and you haven't used the WunderMap, give it a shot on the morning of your next commute.
A few weeks ago I woke up with an expectation for riding to work with temps in the mid-30's. When I accessed the WunderMap it showed that the forecasters had blown it. A map full of 50 degree temps was staring back at me. Sounds good to me!
Wait a second.
What's that one station reporting along my route? 36 degrees?
HA!
"Poor guy's temperature gauge must be toast." I muttered.
Sure enough when I headed out the door I was greeted by 50 degree temperatures and could feel beads of sweat on my forehead during some of the initial climbs on my route.
Then, all of a sudden, it happened.
WHAM!
I rode into an ICEBOX. A wall of very cold air. The huge temperature difference and my light sweating combined to make my teeth chatter.
For about 2 miles I rode in a block of air that truly WAS 36 degrees.
Then it was back to temps in the 50's.
So...when the WunderMap shows a temp out there along your route that just doesn't seem right. Well...
BELIEVE IT.
