Short term Today through Sunday... Generally dry conditions
expected today with high pressure present. Patchy fog will be
possible across low-lying areas for this morning, with otherwise
benign conditions. A weak disturbance looks to move through the
area late tonight, but the main impacts look to be brief shift in
winds. Dry conditions will persist through Sunday. Temperatures
expected to be slightly below normal values for today, with a
few degrees of warming expected for Sunday.
Long term Sunday night through Friday... Clouds will stream into
the region Sunday night ahead of a fast moving upper level trough.
With a west to east trajectory and a deep moisture tap from the
pacific, precipitation will spread across the region with high qpf
amounts beginning early Monday morning. Due to the westerly flow
aloft, little in the way of shadowing is expected along the snake
river plain. This event will begin with snow levels near 4.5-5.5k
feet across baker to valley counties, increasing to about 6.5k feet
along the nevada border. Daytime high temperatures will be within a
few degrees of normal. A moist southwest flow will anchor itself|
over the region in the trough's wake, bringing continued unsettled
weather through the end of the week. A warm front will pass through
the region Wednesday for the next round of increased precipitation.
By this time, even the highest peaks will receive rain as snow
levels will have increased to about 10k feet. Daytime highs will
have warmed to about 10 degrees above normal. By Thursday morning,
the front will have moved north and drier, warmer conditions will
briefly set in. The next round of moisture and decreasing
temperatures will accompany the next system, due to pass through the
region at the end of the week.
Aviation Vfr except for patchy valley fog overnight. Surface
winds: variable, 10 kts or less. Winds aloft at 10kft msl: SW 5-15
Sunday outlook...VFR with mostly clear skies and light winds. Patchy
fog during the early morning hours.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
