Spot Forecast for Alpine Fire
National Weather Service Salt Lake City UT
1038 PM MDT Mon Jun 26 2017

.DISCUSSION...High based storms which developed early this
evening have passed off to the east, and should leave a dry
airmass in their wake. Winds are expected to remain driven
by slope flows overnight through the morning hours Tuesday.

A weather system passing north of the area on Tuesday will
push a weak cold front through the area around midday,
switching winds to the west-northwest for the afternoon
and evening hours. A stray shower or thunderstorm with gusty
erratic winds cannot be ruled out along and ahead of the front,
which will only bring a slight cooling trend, leaving a hot and
dry airmass in place. Another system passing to the north of
the area Wednesday will again bring an uptick in west-northwest
winds during the afternoon, with little if any threat for
precipitation.
