Synopsis
Quiet weather with mostly clear skies, generally light winds, and
above average temperatures expected through the end of january.

Discussion
The main weather story this morning is a significant pattern
change that is currently underway. High pressure and quiet
weather expected for the western u.S. Likely lasting through end
of the january, and possibly longer. An amplified pattern is
developing around a strong low pressure anomaly near the hudson
bay, with a large scale trough east of the rockies, and strong
ridging along the west coast and eastern pacific. This will likely
keep the region in a dry pattern through the next 10 days or so,
after which predictability is too low to speculate. Fortunately,
active weather in early january has pushed the snowpack to around
130% of normal.

Currently, clear skies through most of the region are allowing
for strong radiative cooling. The coldest temperatures in the
forecast period are expected this morning with teens in many areas
and single digits in colder sierra valleys. The very cold surface
temperatures should allow for fog to form in typically fog prone
areas, but dry easterly flow should keep it from being very
widespread.

Northeast gradient winds have formed along the sierra crest with
speeds currently 60-70 mph and may strengthen a bit more over the
next few hours before slowly subsiding during the day tomorrow.

Temperatures along the crest are currently in the single digits,
and for anyone who is wondering, that pushes the wind chill to
around -20 degrees. So, brrr.

Warm air moving in aloft today will bring stable conditions with
relatively strong low level inversions tonight. A disturbance
moving through the pacific northwest will allow for some mixing
the following few days and keep stronger inversions at bay until
the end of the week, when a stronger ridge is expected to build
over the region.

Ridging over the weekend will allow for temperatures to push back
into the 50s in western nevada and with upper 40s in the sierra.

Generally light winds can be expected with relatively strong
overnight inversions possible Friday and Saturday night. Main
changes overnight were to warm and dry upper elevations as
warmer and dry air is expected to build in aloft. -zach

Aviation
Building high pressure should lead to a period ofVFR conditions
across the forecast area that extends through much of the week. The
only exception toVFR is likely to be freezing fog in some of the
sierra valleys this morning... And again Wednesday morning and
Thursday morning... Reducing visibilities below 1 mile. The terminal
with highest probability of freezing fog is ktrk; fog has already
formed there this morning.

Surface winds remain light through much of the week. Winds aloft
will decrease today. There are some residual gusts over the sierra
ridges from the east-northeast this morning. These will subside as
the ridge builds aloft. Turbulence is still a possibility this
morning over and west of the ridge lines. That will be the main
flight level hazard today.

Rev watches warnings advisories
Nv... None.

Ca... None.

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.
