Forecast Discussion
Today is looking like another nice day on the higher summits with far reaching visibilities, warming temperatures, and decreasing wind speeds. High pressure will begin to lose its hold over the region and slide south which will allow clouds to start moving in through the day and into the night. The clouds that do move in will likely be the high cirrus variety during the day and they will still let plenty of sun shine down on the summits. Overnight skies will become mostly cloudy and clouds will start to lower as mid level moisture increases. Tomorrow, clouds will continue to thicken and lower, and will eventually envelop the summits. There are still some model differences with respect to the track of the low. At this point the track is favorable for an all snow event on the higher summits. Warm air in the lower levels may be pulled northward, but it should remain below the summit which continues to support the notion of an all snow event. Also, supersaturated air, cold temperatures, and an area of maximum upward motion will remain a few thousand feet above the summit. This indicates that the best region for dendritic snow growth, or the maximum snow production zone, will be above the summits. At this point all signs point towards a significant winter storm Tuesday into Wednesday.
