Still Socked In…

Around 2pm last Wednesday, the summit sank into the clouds and we’ve been thoroughly stuck in the fog ever since. Low pressure sitting idly over the Canadian Maritime Provinces has produced unwavering conditions and seemingly repetitious forecasts for the latter half of this week.

But as crazy as it’s been living in the fog for the past 3 days, the wildest part is that I don’t expect us to break out of the fog until Tuesday night!

Take a look…

Here we see the low pressure moving in to our north in the afternoon last Wednesday.

And then once it reaches the east coast of Canada, it just lingers, a result of a low pressure area aloft. You can see the low pressure aloft represented by the blue colors overlaying the surface pressure (black lines) on the map.

Here’s where the GFS model shows the same low pressure area tonight.

 And then we can see that by Tuesday night, we still have low pressure in the vicinity!

This low pressure area sitting to our northeast is responsible for the somewhat homogenous conditions we’re experiencing on the summits this week. It is also responsible for the unseasonably low temperatures we’re seeing, with its relative location subjecting Mount Washington to continuous airflow from the northwest.

By now, I certainly long for the stunning views provided by a clear day, but the fog is not without its own splendor, offering a much more intrinsic experience with the surrounding area.

For example, the steady freezing fog has led to some of the most magnificent displays of rime ice I’ve ever seen.

Check out the feathers of rime adorning the sign for the Tuckerman Ravine Trail!
