FORECAST:

A weak upper level trough will push onshore today with light precipitation in a Southerly flow aloft, switching to Southwesterly by this morning. The FL will begin to rise and hover in the 1200 meter range by tonight. Will likely see an impulse of moderate snow in the alpine tonight. Another weak trough for Friday morning with some light precipitation becoming moderate/heavy by Friday night with strong winds. This stronger front will roll into Saturday easing by Saturday night with a weak ridge building into Sunday morning with unsettled weather into Monday. Guesstimates: 8-16 cm by Friday morning, 15-20 cm by Saturday morning, 15-20 cm by Sunday morning. Still a chance most of the moisture will go South for Saturday, more on that as we get closer.

Conditions remain very good in the Spearhead, though the current surface layers, especially on non-solar aspects, will not make a good bonding surface for our next storm cycle...
