Weather?

At the tail end of his trek, Mark is making the dash against the weather to Canada through Washington State.  What will the weather be like the next few days? It's hard to find a good forecast because in the latter portions of the trail, the weather will vary based on altitude.  For a peek into general conditions in the region, here is the forecast from Mt. Baker Wilderness in Washington, through which Mark will be hiking just before reaching the northern border of the state.  Other than general precipitation, for now things don't look too bad, but, again, altitude will determine the real conditions.
