Raining again?

Wanted to go out for a cycle this morning, hoping to clock up 30km at least at a go and check whats wrong with the Polar cadence sensor (measures only >60rev/min) but its raining again! Its been raining since last night, and its one of those irritating rain. Not heavy, not light, but it wets the road anyways. I have slicks on my Felt F1X so its not going to fly. All the wait. Maybe in the evening the sky will open up.
