Area Forecast Discussion
National Weather Service Salt Lake City UT
932 AM MDT Sun Sep 24 2017

.SYNOPSIS...An upper low over Utah will track northeast today,
keeping cool and wet weather in place. Another upper low will likely
impact mainly southern and eastern Utah during the second half of
the week.

&&

.DISCUSSION...Cold upper low continues to drift slowly northeast
across north central Utah near Strawberry Reservoir this morning.
The warm advection wrap around moisture is filling in along the
central and southern Wasatch Front this morning and should persist
through this afternoon as the lower level wind flow becomes
northwest. Temperatures from about Ogden southward to Utah County
should basically straight line today due to the widespread precip.

Farther south the precipitation has become showery and this trend
will continue through today as the low drifts away from this
portion of the state. Have canceled the Winter Weather Advisory
for the mountains of central Utah due to showery nature of the
remaining moisture and due to the fact that the insolation of the
sun will cause roadways to warm rapidly melting any potential snow
accumulations. Patchy dense fog developed across the southwest
valleys and central mountains this morning, which was added to the
updated morning forecast, but should be dissipating by 1100.

Have improved the sky conditions over eastern Utah zones this
morning and afternoon as the northwest flow setting in there is
downsloping and clouds have been dissipating past few hours.

The Winter Weather Advisories for the northern mountains of Utah
look in good shape. However, snow amounts in the central Wasatch
may end up being a few inches greater than current forecast as the
favorable northwest flow sets in this afternoon but should not
impact roadways, as daytime insolation will help melt the road
snow.


&&

.AVIATION...Ceilings will bounce between the low end of VFR and MVFR
today as a cool and moist northwest flow becomes established by this
afternoon. Rain will gradually end by early this evening, though
ceilings will likely remain in the 3-4 kft range through around
mid- evening before breaking up. Fog could become an issue later
tonight, especially if winds turn light and skies clear. Surface
winds should remain out of the north until at least mid-evening.
