Synopsis An upper trough will exit utah this evening, followed
by a stable west to northwest flow aloft early in the weekend. A
couple of weather disturbances moving through the northern
rockies late Saturday night through Sunday will nudge a dry front
across northern and central utah Sunday. Cooler temperatures will
follow the front to begin the new week.

Short term (until 00z Tuesday) The upper trough that moved
through the area today will exit utah by early this evening.

Lingering showers along the trough axis across the uinta range of
northeast utah will exit the state before sunset.

A developing low amplitude anti-cyclonic west-northwest behind
the exit trough will maintain stable conditions across the state
this weekend. A couple of weather disturbances moving quickly
eats through the northern rockies this weekend will nudge a
surface front south across the northern half of the forecast area
late Saturday night through Sunday. Ahead of this front slightly
drier and warmer air will work into the state, followed by a new
surge of cooler and even drier air for late Sunday through Monday.

The low-level cold advection trailing this front will have no
real support to sustain any significant lift. Dynamic support for
lift will remain well to the north of the front, as will any
substantial moisture source. The air mass will also remain quite
stable as mid-level temperatures remain relatively warm across the
forecast area.

Long term (after 00z Tuesday) a ridge builds over the forecast
area by the middle of next week, allowing high pressure to redevelop
and temperatures to return to near normal. An eastward shift in the
ridge will allow moisture to surge into the state and bring
increased sky cover and pops toward the end of the forecast period.

Daytime heating on Thursday and Friday along with increased moisture
will likely initiate convection over the higher terrain during the
afternoon hours.

Aviation Light northwest winds at the slc terminal will become
southeast after about 04z this evening.VFR conditions will prevail
through the TAF period.

Fire weather The upper level trough across extreme northeast utah
will exit the state by this evening. The showers associated with
the trough will remain over the eastern uinta range, and will end
before sunset this evening.

A stable air mass will trail the exiting trough this weekend. Patchy
residual moisture could generate some terrain-based convective clouds
Saturday afternoon.

A trough moving east across the northern rockies Saturday night through
Sunday will push a surface front south across northern central utah
Sunday. Winds will be an issue, both pre-frontal and post-frontal Sunday
through Sunday evening. Increasing low-level cold advection trailing
the surface front along with falling surface pressures during the
day will bring a steady increase in south winds ahead of the front.

Behind the front increasing west-northwest winds along with good
vertical mixing will produce strong and gusty post-frontal northwest
winds in the both the valley and mountain locations into Sunday
evening. Numerous fire weather highlights have been issued to
address the wind issue.

Ahead of the front significantly drier air will be drawn into the state,
followed by somewhat cooler temperatures behind the front to begin the
new week. Low humidity values will exist statewide, with only fair to
poor nighttime recoveries expected into early next week.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
