... Cool and very wet Pacific storm system headed into western
Wyoming today...

The strong Pacific storm headed towards western Wyoming will
continue to bring copious amounts of precipitation with it.
However, temperatures with this Pacific air mass will be much
warmer than originally thought, keeping snow accumulation levels
high... at or above 9500 feet through tonight... with snow mixing
with rain below this level down to about 8500 feet. High Mountain
passes such as Teton and togwotee passes will experience periods
of Wet Mountain snow this morning that could cause slushy
conditions on the roadways and slowing travel times. Otherwise,
anywhere from a half an inch and an inch and a half of liquid
precipitation can be expected to fall between now and Friday
morning across the western mountains and valleys. Heaviest
accumulating snow over the same time frame will range from 3 to 8
inches above 9500 feet... with locally higher amounts possible.
