Synopsis
The cool and unsettled weather pattern in place will continue
through the remainder of the week and into the start of next week
as a persistent trough takes up residence over the western us. The
coming holiday weekend is expected to see brief warming and
drying.

Short term (through 00z Saturday) Persistent rain showers began
early this morning across far northwest utah and moved east,
becoming more widespread. There was a hint on radar of the lake
playing a part to enhance rain showers as they moved into the
northern wasatch front. From north of salt lake city through
ogden, widespread rain persisted for most of the day and just now
before 4 pm is the coverage beginning to lighten up a bit.

Isolated thunderstorms and small hail was also observed from
storms in the southwest portion of utah through the northern
wasatch front. Accumulating snow was observed along portions of
i-70 east of i-15.

Taking a big picture step back, as the upper level low exited east
of the rocky mountains this morning the strengthening and filling
low pressure further stretched and tilted the longwave trough back
through oregon. Utah happened to be under an area of diffluence
aloft and somewhat favorable instability, with forecast soundings
indicating over 300 j kg of instability this afternoon.

As the longwave trough shifts south overnight into Wednesday, the
upper level flow will turn more easterly especially across
northern utah. During the day Wednesday as the trough unfolds,
winds will become stronger and even more so Wednesday evening
through Thursday. Forecast models have advertised this for several
runs and confidence is high enough to issue a wind advisory for
the northern wasatch front and cache valley focusing on downslope
canyon winds.

Thursday will be another unsettled showery day
across the area before the trough becomes sheared apart and ejects
to the northeast. This will leave Friday in a transition day with
less chances for showers and precipitation and an opportunity for
a brief drying and warming trend to start the holiday weekend.

Long term (after 00z Saturday) The unsettled pattern with a
longwave trough over the west will continue through the long-term
forecast period.

The next system of note will dig southward along the california
coast and close off over the weekend before it moves inland toward
utah Sunday night and Monday. This disturbance is further west than
the previous ones which should result in more of a break from
precipitation Saturday and Sunday. With a southerly flow and
somewhat unstable airmass, some widely scattered mostly mountain
showers and thunderstorms are still possible over the weekend.

Temperatures should increase to more seasonal values on both days.

The upper low makes it move toward utah Sunday night and crosses the
state on Monday. The ensembles and operational models are all fairly
consistent with the timing and strength. Precipitation chances
will ramp up starting Sunday night, though the best chances will
be during the afternoon and evenings Monday and Tuesday. Thus
Monday and Tuesday look to be showery and slightly cooler than
normal.

Past the long-term period, the ensembles still hold on to a trough
of some sort over the west through next Friday.

Aviation Showers and low ceilings at MVFR conditions at the
kslc terminal will continue through 00z-02z before lifting to 6000
ft. Winds out of the west-northwest may become erratic due to
showers but will persist during the overnight hours. Winds should
become light by 05z-06z and southerly. The onset of additional
rain showers by 12z will once again bring ceilings back into MVFR
range.

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.
