corrected and uncorrected errors on MB8600 jumped

I've been monitoring my corrected and uncorrected errors with a script on my MB8600 for the past few months. Things have been pretty normal with the uncorrected total under 1000 errors. The last day or so the number of corrected and uncorrected errors have skyrocketed and I have not done any coax changes within the house. Can someone take a look at my screen shot and give me some ideas? Is it possibly due to the recent heat wave we are seeing here in the Denver area? I'm open to suggestions. thanks
