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.

Discussion
Mid-level circulation retrogrades from nevada into california
overnight. This usually increases the odds of easterly
canyon downslope winds setting up in time. 700mb cold advection
from wyoming, with an increasing pressure gradient will provide an
uptick in winds canyon winds Wednesday morning, however the best
period for the synoptic setup is Wednesday evening through
Thursday morning.

Eastern extent of height falls associated with the storm system
currently over southwest utah will slide southwest as well,
meaning large scale lift will become less supportive of
precipitation across southern utah as the night progresses.

Temperatures will have to be watched near cedar city, as some
outlying areas may near a hard freeze if enough drying clearing
occur. Right now it looks like a close call.

Up north, precipitation chances increase from east to west as
initial easterly cold advection sets up overnight. Would expect
wasatch front and cache valley conditions to improve tomorrow
morning as the downslope component begins to strengthen.

Previous discussion
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.

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
Southeast drainage flow has already set in at the kslc terminal
this evening. As easterly flow develops across the region
overnight and tomorrow, winds at the kslc terminal may increase
and become quite variable due to eddies off the vicinity terrain.

Rain will bring a lowering in ceilings and visibilities overnight
before ending Wednesday morning.

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.
