Smoking in damp and rainy weather

[bbquine]

Up here in the Pacific NW, there are not many days during winter which are dry. The typical weather is mostly damn and cloudy with occasional rain. I have solved any direct rain issues with a tarp over the pergola above my smoker, but I've been wondering if there are any more tricks for cooking humid weather. I'm running a Masterbuilt GS40 and mostly using oak chunks. The smoker is mostly unmodded except for foil wrap around the chip pan.

Uhhh......don't you use your golfing umbrella like I did yesterday when smoking some cheese?
