A developing low pressure trough
with a triple point frontal system will bring another round of snow to the
Cascade Mountains tomorrow night.
Similar story as the previous storms; east flow, warm front pushing
freezing levels up, followed by a cold front.
Storm totals by Monday morning could exceed a foot of new snow.
