Area Forecast Discussion National Weather Service Boise ID 159 PM MST Fri Dec 4 2020

SHORT TERM. Tonight through Sunday night . A small and dry upper level low remains overhead this afternoon, and a larger and more moist system is headed in late Saturday night and Sunday. Neither of these will be strong enough to remove the inversion, but the stronger system will bring in cloud cover and light snow for parts of southeast Oregon and the higher terrain of Owyhee County. Temps will show little day to day variation in the short term, and winds will be light. Overall, the forecast was not changed much today.

LONG TERM. Monday through Friday . The upper level ridge rebuilds on Monday for continued stagnant conditions and areas of fog/stratus through the middle of next week. Dry conditions are expected on Monday and Tuesday with temperatures near normal. Ensembles indicate a breakdown of the upper level ridge late next week. This will bring more zonal flow resulting in a slight chance of snow Tuesday night and Wednesday over the northern mountains. A second trough is forecast to move through the area Thursday/Friday, which will bring a continued chance of snow to the higher terrain. Confidence remains low with this system, but vertical mixing should improve with less air stagnation in the valleys. Ensemble means indicate another upper ridge building along the west coast late next week with the pattern becoming more active.

AVIATION. Mainly VFR. Patchy fog will develop in sheltered mountain-valleys late Saturday morning. Surface winds: generally east to southeast 5-15 kt. Winds aloft at 10k feet MSL: north to northeast 5-15 kt.

Weekend Outlook . VFR except patchy valley fog late nights and mornings. Light and variable surface winds. A weak low pressure system may bring light snow to southeast Oregon on Sunday.

AIR STAGNATION. The inversion will remain in place through the weekend and likely well into next week, as the incoming systems will not be strong enough to remove it. Air Stagnation Advisories remain in effect through Saturday, and will likely be extended.

BOI WATCHES/WARNINGS/ADVISORIES. ID . Air Stagnation Advisory until 11 AM MST Saturday IDZ011>014-016-028-033. OR . Air Stagnation Advisory until 11 AM MST /10 AM PST/ Saturday ORZ061>064.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
