Synopsis A trough will move across the northern rockies
Thursday with the associated cold front pushing into northern utah
Thursday morning then reaching central utah by evening. A dry
northwest flow will prevail into the weekend.

Short term (through 00z Sunday) A thin layer of moisture over
the uintas and along the spine of the mountains stretching south
to the boulder mountain area has bubbled up into flat cumulus. Do
not expect any precip from the cumulus over the southern or
central mountains, but a few sprinkles may reach the higher
terrain of the uintas into this evening.

A trough moving across the northern rockies Thursday will push
its associated cold front into northern utah Thursday morning and
into central utah by afternoon. Southwest winds will increase
ahead of this approaching cold front as well as behind the cold
front in the uinta basin and castle country areas. An area of
instability associated with the cold pocket aloft will bring a
minor threat of showers to the raft river range in extreme
northwest utah Thursday afternoon. Otherwise, dry conditions will
prevail.

Temperatures will cool by about 5-8 degrees across the north
Thursday and only a couple of degrees elsewhere. Temperatures
Thursday night will cool also by 5-8 degrees under clear skies and
dry air mass. Have undercut MOS guidance by a few degrees.

Instability showers are possible over the uintas Friday afternoon
as the temperature difference between 700 and 500mb exceeds 20c
degrees and the lifted index approaches -2.

Little change in the weather is expected Saturday.

Long term (after 00z Sunday) The long term period will
generally be characterized by a dry northwest flow with mid level
ridging remaining centered to the west of the forecast area. This
will keep temperatures near or slightly above climo through the
middle of the upcoming week. By Wednesday moisture is expected to
begin creeping into southern utah and as such have retained slight
chance pops across the higher terrain near boulder mountain for
day 7.

Fire weather A trough moving across the northern rockies will
push a cold front into northern utah Thursday morning and into
central utah by late afternoon. Poor to very poor rh recovery
tonight will set the stage for low minimum rh values on Thursday.

In addition, southwest winds will increase ahead of the front over
the west central and southern valleys, while southwest winds will
shift to westerly across the northern and eastern zones Thursday
afternoon. Temperatures will cool by several degrees in the north
Thursday, but remain nearly the same as today over the central and
southern fire weather zones. A dry westerly flow will prevail
through the weekend with temperatures gradually warming to a few
degrees above normal. Rh recovery after tonight will be somewhat
higher but still only fair recovery at best through the weekend.

Aviation Vfr conditions will persist at the kslc terminal
through the TAF period with northerly afternoon winds shifting back
to the south southeast by 03-04z. Southerly winds will ramp up
slightly during the morning hours tomorrow and shift to the
northwest once again around 21z.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
