I was curious about that temparature drop too.

The cloudburst explanation makes the most sense to me; also it fits in 
with the prounounced spike in water flow at the Tantalus Creek stream 
gage: http://waterdata.usgs.gov/mt/nwis/uv?site_no=06036940

As for Steamboat's long-period cycles of minor activity, I couldn't agree 
more with your assessment!
