Cooler near the Lake??

So i rolled into work friday looking to enjoy what could have been a really nice day to ride. It was about 62 degrees when i left and by the time i was half way there - the knee warmers and arm warmers were almost too much as the temps were rising. No when i got into the loop, the usual lake effect cooling came into play, but it was still beautiful downtown. Lunch time was partly cloudy, but still had all the optimism of a beautiful ride home. I checked the temp at 5:30pm, and it said 52.. now that cant be right i thought, so i went outside to confirm. The weather channel was wrong, the clock / thermometer thing outside our building showed 48 degrees!!!
I stretched my knee warmers down to leg warmers and pulled out the rain cape luckily, but i had to run down to niketown to pay for overpriced running gloves. I froze my arse off on the ride home, that's for sure. I guess the spring time cooler by the lake was in full effect friday.
