FORECAST:

The upper level ridge will weaken somewhat today allowing for cooler marine air to be pushed into the area in a South-Southwest flow aloft. The FL will peak out today at around 3500 meters. The ridge will begin to migrate eastward Wednesday and flatten, with clouds moving in by the afternoon. Depending on what the trough does moving in from the Southeast we could see some precipitation develop Wednesday night. Thursday is looking unsettled with the potential for some isolated showers. Friday is looking like a nice day with the chance of some showers in the evening. This pattern continues into the weekend but there are some differences in the models so more on that as we get closer.
Guesstimates: 0 mm by Wednesday morning, 3-6 mm by Thursday morning, 3-6 mm by Friday morning, trace-2 mm by Saturday morning.

Ascended Sigurd Creek and Pelion's northwest glacier Saturday May 12. Skins on at 940 m. Crossed Sigurd creek at 1060 m on a small lake covered in a melting snowpack, not sure how long that crossing will be possible. Stopped 40 m shy of the summit due to a large cornice overhanging the east side of the ridge and steep sun affected slopes on the west side. Great corn skiing on the glacier.
