Synopsis High pressure will strengthen across the region today,
and remain in place through the remainder of the week.

Discussion Mid level ridging continues to build aloft across
the great basin region, with remnant moisture streaming along the
northern periphery of its expansion. Did note a few very light
showers earlier this morning, but in large increasingly stable
conditions are namely yielding mid level cloud cover across the
north. Do anticipate a net decrease in cloud cover for most areas
this afternoon as the upstream ridge axis begins to shift overhead
and further northward expansion of the ridge occurs, but not
completely. Going forecast handles this well and have made no
updates this morning.

Previous discussion This ridge will become the dominant feature
across the region through thanksgiving, and with a combination of
overnight cloud cover and warming temperatures aloft, weak valley
inversions should erode allowing for a warming trend across all
areas through thanksgiving. A shortwave trough is forecast to
crest the ridge axis as it traverses the northern rockies Thursday
night, pushing a shallow frontal boundary through northern utah
Friday. Anticipate only a slight cooldown across the north while
the south remains unaffected by this feature.

The weekend starts off the extended period under building and
strengthening high pressure across the desert southwest. Southwest
flow aloft increases as the weekend comes to an end and warm
advection prevails over the great basin.

A shortwave trough begins to swing inland into northern
california Monday, as global models have come into better
alignment with this feature. Differences still reside among the
models, especially timing, however the track and location are
fairing better sync moving through the great basin. Increasing
southwest winds ahead of this feature Monday are being advertised
by models, and as such have increased winds across the west
deserts Monday. As the wave tracks east into wyoming, cold air
aloft sinks southward bringing a rather weak baroclinic zone
through northern utah. Some moisture associated with this feature,
and perhaps more behind the departing wave may give way to
showery conditions Tuesday into Wednesday. Speaking of cold air
aloft, snow levels look to lower to benches or valley levels
depending on the model guidance. Confidence in these details is
still very low with this being the far extended, but the pattern
is evolving this direction.

Aviation Occasional ceilings at the slc terminal near 6500 feet
agl should gradually lift through 21z. Light and variable winds are
expected to become northwest by 18z. Due to inversion conditions,
haze will remain across the salt lake valley through the day, though
visibility restrictions below 6sm are not expected.

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.
