SHORT TERM. Tonight through Thu night. A major Pacific storm will dump copious amounts of snow starting tonight in the higher elevations of central Idaho, and spread during the morning to the ID-WY border Wed morning. The precipitation should be continuous in accumulation through at least Thu night, with portions border region continuing to receive moderate snow beyond this near term period. Temperatures are very mild, with upper 30s and 40s for many elevations below 5000ft, with a warming trend through Thu. Overnight lows will also turn mild with all the cloud cover. Winds continue to look strong for Wednesday, from the south, which means from Burley to Fort Hall that downslope conditions will retard not only snow accumulation but total precipitation, and these areas southward to the Utah border will be the least affected, with much lighter accumulation. Winter Storm Warnings and Winter Weather Advisories continue unchanged from this morning. Messick
LONG TERM. Friday through next Tuesday. Two distinct weather systems are expected to impact East Idaho late this week into early next week. On Friday, and upper trough will finally drive eastward from the Pacific coast. Models are showing a split in the flow with a cutoff over the Desert Southwest. As a result, we should not see very heavy snowfall as the trough and associated cold front passes through the region. Models start building an upper ridge across the Rocky Mountains starting on Saturday, though each long-term model wring some precip out of the atmosphere via upslope forcing through the ridge axis. This precip should be fairly light and confined to the higher terrain through Sunday. By Monday, ridging amplifies downstream with a deepening southwesterly flow aloft developing throughout the day Monday. Models are showing some moisture advancing into the region as early as Monday morning with upper troughing deepening upstream. Ensemble members are at odds with just how deep the trough will be and, as a result, the speed of its movement. Overall, we should see another round of snow with this second weather system, though details remain unclear as to how much and how widespread this will be. Hinsberger
AVIATION. Multiple low cloud layers is making it difficult to discern the LIFR ceilings from the MVFR/low VFR ceilings in the Eastern Magic Valley. KBYI begins the period in MVFR, but upstream observations at Jerome and Twin Falls show ceilings of 500 and 1600 ft respectively. The multiple layers are setting up some seeder- feeder action at KBYI, and that may bring a periodic lower ceiling. Elsewhere, we're waiting for the approach of the main event--the atmospheric river. Expect KSUN to see snow beginning around 12Z. Snowfall rates from BUFKIT soundings for KSUN indicate visibility may approach minimums, though NBM guidance is more optimistic. Low- level wind shear is also a possibility with a strong south flow coming to the boundary layer tomorrow morning. Hinsberger

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 numerous 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.
