Area Forecast Discussion National Weather Service Boise ID 834 PM MST Wed Dec 11 2019
DISCUSSION. Precipitation is coming in a little faster and wetter this evening. Therefore, the forecast will be updated for higher pops and rain/snowfall amounts this evening. A Winter Weather Advisory that is in effect for the Boise/West Central Mountains late this evening will also be updated. Precipitation will remain widespread through Thursday, with snow levels rising to 5000 feet north (Baker to McCall) and 6500 feet along the Nevada border.
AVIATION. Mountains obscured. Widespread MVFR and local IFR/LIFR conditions in rain, snow, and low ceilings in eastern Oregon and the west central Idaho mountains spreading across southern Idaho 04z-08z and continuing through Thursday. Snow levels 3500-4500 ft MSL. Surface winds southeast-southwest 10 kts or less becoming west-northwest around 10 kts after 18z/Thu. Winds aloft at 10k ft MSL west 40-50 kts becoming west-northwest 30-40 kts after 18z/Thu.
PREV DISCUSSION. SHORT TERM . Tonight through Friday . Next Pacific storm system reaching the Pacific Northwest tonight bringing widespread precipitation through Friday morning. Precipitation will begin in southeast Oregon late tonight reaching Southwest Idaho after midnight. Snow levels will continue to rise through Thursday reaching 6000-6500 feet across along the Nevada border to 5000-5500 feet across the West Central Mountains. Thus, the valleys will remain all rain. Mountain valleys below 5500 feet could potentially see rain mixed with snow Thursday afternoon however they should see snow for the majority of the event. Snow amounts will range from 3 to 6 inches in the mountain valleys to up to a foot of snow above 6500 feet. Precipitation will tapper off Friday afternoon with colder temperatures following the exiting storm system. Temperatures will remain above normal through the period.
LONG TERM . Friday night through Monday . Snow levels fall to the valley floors on Saturday as a frontal system passes by along the NV border. Light snow accumulations are possible with this system on Saturday morning. A secondary system will pass across SW OR an northern CA on Sunday keeping a threat of snow showers across the area, mainly across SE Oregon. Temperatures will be near normal through this period.
Monday night through Wednesday night . Partly to mostly cloudy skies are the expected conditions starting Monday as (dirty) ridging extends across the region. However, conditions are expected to gradually deteriorate as a moist, upper trough makes it way into Southeastern Oregon starting early Wednesday. As this trough migrates eastward, look for scattered snow showers to spread eastward (along with it), mostly affecting the mountains and foothills. Winds are also expected to increase to breezy levels around that same time frame. Strong southeast (downslope) surface winds across the Treasure Valley should help to bump up temperatures. As a result, average high and low temperatures are expected to measure in around three degrees above normal.

I do not sell or share any user data or anything else for that matter. I do not keep site logs longer than I need to to keep bad actors off the site. Basically, I delete them after looking at them.

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

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.
