Area forecast discussion
National Weather Service Salt Lake City Utah
1014 PM MDT Wednesday Oct 1 2014
Synopsis...a cool northwest flow will remain over the area
tonight into Thursday then begin warming up. Strong high pressure
will stay centered over the West Coast states keeping a dry
northwest flow over the region through at least early next week.
Discussion...the cool upper trough that crosses northern Utah overnight
through this morning has moved out of the County Warning Area this evening and the few
remaining clouds and possible flurries should dissipate by
The tight northwesterly surface gradient that swept in behind the
cold front brought breezy northwest to north winds to most of the
area through late afternoon. The tightest gradient has shifted into the
southern County Warning Area and winds have been dropping off over the north.
Expect winds to decouple across all but the Dixie area through the
early morning hours as the gradient shifts out of the County Warning Area.
The clear skies...diminishing winds and chilly airmass should
allow temperatures to dip to near or below freezing in normally colder
valley areas across the County Warning Area tonight with local frost
possible...including outlying portions of Utah County and possibly
the lowest portions of southern Salt Lake County.
It still appears the Uinta Basin...the Sanpete and Sevier valleys
and the southwestern valleys near Cedar City could reach 28
degrees and will keep the existing freeze warning unchanged.
The ridge along the West Coast remains in place through the
weekend keeping a dry and warming northwest flow over the County Warning Area
starting Thursday and continuing into next week. A weak system
dropping into the northern plains could keep a few clouds and some
increase in winds over the northestern County Warning Area tomorrow but that is about the
only weather threat for at least the next 7 days.
No updates planned.
Aviation...winds will remain southeasterly at the kslc terminal
through Thursday morning.
Utah...freeze warning from 3 am to 9 am MDT Thursday for utz011-014-016.
