The morning report had 6” at mid and 9” up top, with 3.5” at mid falling overnight. By 9am, and additional 2” of snow had fallen at mid and top, and by 11am, another 3” mid and 1” up top had fallen, and it is currently snowing.
Snowfall should increase again this afternoon as a trailing wave passes over the area, producing another 3-6” of snow. Snowfall will rapidly diminish after midnight as the airmass stabilizes and winds increase. Considering that 5” of new snow has already fallen at mid-mountain between 5am and 11am, I’m expecting tomorrow’s report to be in the 8-12” range.
Snowfall will continue to taper off during Saturday and might even end for a short time during the day and possibly into the evening. Sundays forecast storm has slowed a bit, shifting some of my original 6-12” prediction to after the morning report. So I would expect 4-8” on both Sunday and Monday morning to be reported, with most of the snow for Monday occurring during the day Sunday. Snowfall will be becoming lighter but still persistent starting later Sunday and lasting through midnight Monday before ending, likely adding another 3-6” during the Monday that will be reported Tuesday morning.
Dry air and warming mountain temperatures will overspread the area in earnest later Tuesday into Wednesday with beautiful sunny days and cold valleys due to inversions reforming and strengthening. The grazing wave for Thursday may be even further east than earlier forecast, minimizing any cloudiness associated with it as the western ridge rebounds over our area Friday into the weekend.
There are indications that Pacific storms may weaken the ridge and allow energy to move into the west coast and then over our area later in the weekend or early in the next workweek, but lots of model disagreements at this time.
