Synopsis The storm system that has been impacting the area will
start to shift east today. High pressure aloft will spread into the
area tomorrow, with a transition to a more westerly flow for
the early part of next week.

Short term (through 00z Tuesday) An upper trough remains over the
area this morning with its axis extending from far northern baja
california through northwest utah and into central montana. This
trough is starting to shear out and will shift east today, and as a
result, will see a general decline in snowfall throughout the day.

In the meantime, the main closed low remains in place along the
cal arizona border, while a secondary circulation is noted over
southwest wyoming and continuing to eject northeastward.

Some moisture is still spreading into portions of south-central and
southeast utah early this morning due to a south-southwest flow
aloft around the closed low, but the flow will become more northerly
from the surface through 700mb after 16z which should cause snow in
that area to wind down quickly. Across northeast utah and southwest
wyoming, snow also remains in place due to the aforementioned
secondary circulation. However, as this feature weakens, snow in
this area should also decrease mid-morning. From mid-morning through
the afternoon hours, the focus for snow will transition to the i-15
corridor and adjacent mountains across central and southwest utah as
northerly flow becomes established behind the trough as it shifts
east. Have dropped a few zones from the existing suite of winter
weather highlights where additional accumulations are expected to
remain minor.

In addition to the snow, the other main concern overnight was canyon
winds along the wasatch front. The winds were quite gusty for a few
hours late this afternoon and this evening. However, the winds have
already peaked as the mslp gradient has turned more northerly and
the 700mb flow has also started to weaken and back to more
northeasterly. Although some localized gusts over 30 mph will remain
possible early this morning, wind advisory criteria is no longer
expected to be met, so that highlight has been dropped.

The storm will clear out of the area this evening, allowing a
shortwave ridge to build into the area. Warm advection at 700mb will
strengthen on tomorrow, with some moisture reaching northern utah.

Some snow may be possible along the idaho border, but the storm
track will remain too far north of the area to have significant
impact on utah. A more zonal flow will then develop for the first
half of next week. Will continue to see storms cross north of utah,
which will keep some clouds in place over at least the northern half
of utah. Far northern utah will continue to see a chance of
precipitation Sunday and Monday, but the rest of the forecast area
is expected to remain on the dry side. Temperatures will trend
warmer during this time, and snow levels are expected to climb above
the lower valley floors by Monday afternoon.

Long term (after 00z Tuesday) Global suite continues to advertise
a pattern change for the long term period, and thereafter. The jet,
mean storm track, and associated energy will shift just north of the
area, with a near zonal flow standing pat in place. Continue to
retain a slight chance of precip along the ut id border (focused
Monday night into Tuesday) with the passing of a grazing wave
rippling through the northern rockies, but as a whole have continued
to taper back pops as the large scale set up just doesn't fit with
some guidance qpf. Building heights, stable profiles, etc.

Warmer temps will be the norm, and have adjusted them up higher than
previous forecasts. Solid flow and good mixing potential will most
likely allow for temps 5-10 degrees above climo Tuesday on.

Aviation MVFR to low endVFR snowfall will continue at the kslc
terminal through 13-14z. An additional half inch of snow remains
possible on untreated surfaces through that time. Ceilings are
expected to lift but remain below 6000ft agl through mid
afternoon... Prior to thinning. Light and variable winds currently in
place are expected to become a prevailing north wind between 14-16z.

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.
