Thatcher, Emigration Summit, St. Charles, Montpelier, Georgetown,
Grace, Soda Springs, Henry, Bone, Wayan, and Swan Valley
438 AM MST Wed Nov 20 2019

Currently expect around Trace to .10 of inch of snow up
to around I-86 and then extending up to Idaho Falls. These areas
will have the cold air so any precipitation late this afternoon
into early evening will likely be all snow. Some models are
showing the possibility of 1/2 - 1 inch but these amounts would
be on the high end. If the higher amounts occur there will be
some blowing snow with the breezy winds. However, the lower snow
amounts are most likely. These northern areas, including Pine
Creek pass, may not have much moisture reach them.

Farther south in our southeast areas expect more snow with the
heavier snow starting this afternoon. The snow levels will start
much higher around 6500 feet late this morning into the early
afternoon. The snow levels will drop to around 5000 feet by
Thursday morning. For storm totals, expect 2 to 4 inches of snow
for most mountains above 6000 feet. The Wasatch mountains could
see 3 to 7 inches of snow. Emigration Pass will have the greatest
impacts with 2 to 4 inches of snow. Georgetown Summit and Geneva
Summit will get around 1 inch, maybe slightly higher, of snow. All
other passes look to get less than 1 inch, though 1 inch is not
out of the question.

exceeding a foot will be common, with the heaviest snows across
the southern mountains.

Precipitation will begin to wind down late Thursday afternoon,
