Wider weather episode

A high pressure system had built into the Yukon and B.C. as a 965 MB storm force low moved into the central Gulf of Alaska. Strong north wind developed for Downtown Juneau, but no damage was reported on the night of 1.19.12. The storm deepened into the 950s with very strong surface pressure gradients, cold air, and heavy snow for most of the Panhandle. This system was so mature that it took two days to dissipate as the center was finally pushed to Vancouver Island on the 1.22.
