It is possible that cold or inclement weather might have an indirect effect on Comcast speed.

Comcast service is "hard-wired" from their network center to your home through other shared network lines. The communications network from TV to Comcast servers has a capacity. We all share that capacity/bandwidth. If more people than normal are using their Comcast internet (during cold or bad weather) then each of us gets a smaller slice of the bandwidth pie and slower response time. This is such a densely populated area and it appears, from what others have posted, that Comcast has not built a leading edge technology network here....so, response times vary.

I sure wish we had a reliable, reasonably priced, high speed alternative to Comcast and Embarq/DSL. By the way, DSL users don't usually see the same variations in response time as Comcast since each household has its own dedicated line.
