FORECAST:
An upper low will bring periods of light precip this am in a Southerly flow aloft. Drying trend this afternoon as a weak ridge builds into Saturday. The FL today should hover around surface. We should see a few sunny breaks this afternoon. A mix of sun and cloud for Saturday with seasonable temperatures. Another weak front arrives early Sunday morning with periods of light precip. A series of frontal bands for next week as a deep low in the Gulf of Alaska sends wet warm weather our way for most of the week. Thursday could be a soaker. More on that as we get closer. Guesstimates: trace-2 cm by Saturday am, 0 cm by Sunday am, 2-6 cm by Monday am.
By Wednesday, the recent storm snow appeared to have locked up, as explosive control work produced only limited size 1 loose dry results in the low density surface snow over the crust.
A widespread natural cycle occurred during the storm Monday night through Tuesday, storm slabs size 2-3 and loose wet size 1-2.
