YESTERDAY:

Satellite image from Sunday afternoon.
2240 meters -6, Winds were 45-60 KPH SE--Horstman Hut
FORECAST:
A weak upper level trough will bring periods of light precipitation for today in a Northwesterly-Westerly flow aloft. The freezing level will rise to around 1400 meters later today as a warm front pushes through. A stronger front pushes through on Tuesday with the FL hovering in the 1500 meter range. The brunt of the precipitation will occur Tuesday night into early Wednesday morning. Weak ridging on Wednesday will bring dry unsettled weather into Thursday before the next upper level trough arrives Friday. Guesstimates: 4-8 cm by Tuesday morning above 1000 meters, 10-15 cm by Wednesday morning above 1200 meters., 4-8 cm by Wednesday morning above 1000 meters.

We could use a few weeks of Pacific Frontal Systems.
