Snow on Wednesday expected to accumulate in high elevations, switching to rain/mixed precip below 7000-8000 feet on Thursday. The steady warming accompanying the system makes the accumulation forecast particularly tricky as most of the area warms above freezing by Thursday afternoon, but this at least suggests impacts may be shortlived. Liquid equivalent and rainfall amounts will be highest on Thursday. Periods of moderate snowfall rates possible Thursday morning.
