SHORT TERM. Tonight through Thursday night. Early afternoon satellite imagery was showing a low pressure center advancing into WRN Canada while regional radar imagery was highlighting a swath of associated precipitation advancing into WRN Idaho ahead of the trough. Numerical models shear the low east along the Canadian border tonight and Wednesday as the attending precipitation sweeps through SE Idaho. Enhanced snowfall is expected across the west slopes of the CNTRL and ERN mountains tonight transitioning to the northwest slopes and weakening during the day Wednesday as the trough shifts east of the region and a ridge of high pressure builds over the NW coast. Snow totals should remain below advisory levels and thus no particular highlights are warranted at this time.

The ridge of high pressure continues to expand north and eastward Wednesday night through Thursday night with overrunning moisture bleeding into the CNTRL and ERN mountains where light NW upslope snowfall will persist. Daytime temperatures should remain near climatological norms throughout the forecast period. Huston

LONG TERM. Friday through next Tuesday. Models continue to show an active progressive pattern through the weekend. A shortwave trough will make its way into the area Friday morning, bringing the initial round of snow to the Central Mountains and expanding into the rest of southeast Idaho by Friday afternoon. Both GFS and ECMWF show a brief period of ridging Friday night into Saturday with the ridge axis passing through by Saturday evening. At about that time, a southwesterly flow will slam into the Central Mountains again, forcing some enhanced snowfall as an upstream trough approaches. By Sunday, precipitation will likely overspread the rest of the forecast area with rain expected in the lower elevations. Models appear a bit more in line today with the extended periods with the timing and amplitude of Sunday's weather pattern. Temperatures should continue to remain above normal through the weekend, cooling slightly on Monday. Hinsberger

AVIATION. A cold front will bring some snow to the region tonight along with some winds. KBYI and KPIH may be low enough to have some rain or rain/snow mix as snow levels are around 5000'. Winds will increase as the front passes and peak in the early morning hours. Ceilings should be MVFR for the duration of the snowfall with KSUN seeing visibility dropping to IFR. Expect to see some gradual improvement in the ceiling late tomorrow morning. Hinsberger

AIR STAGNATION. Cold air remained trapped in a number of our mountain-valley systems today and an Air Stagnation Advisory was issued for Franklin County. Numerical models show considerable moderation of the inverted temperature profile tonight and early Wednesday as a low pressure trough, associated precipitation, and stronger winds sweep through the region. A ridge of high pressure will rebound across the NW coast Wednesday afternoon and then shift east over Idaho Thursday with deteriorating temperature profiles expected by Friday. Huston

PIH WATCHES/WARNINGS/ADVISORIES. 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.
