KEY MESSAGES

- Light snow showers will continue throughout the day across our eastern mountains, amounting to an additional one to two inches.

- Conditions turn mostly dry this weekend, but northerly flow aloft will support very light snow showers across high elevations.

- Mild unsettled conditions are forecast for most of next week, along with periods of windy to very windy conditions.

The upper trough axis is now shifting through UT/CO/WY with Idaho on the periphery of an area of high pressure as we head into the weekend, resulting in a transition to drier and warmer conditions. Light snow showers will continue across the eastern mountains through the afternoon, bringing another inch or two of snow to these areas. Area observations indicate wind gusts still in the range of 25 to 30 mph early this morning across the South Hills and foothills of the Beaverhead and Lost River mountains. Breezy winds will persist in these areas and return elsewhere this afternoon before becoming much lighter Saturday. Temperatures will gradually warm today and Saturday, but northerly flow aloft will keep temperatures only slightly above seasonal norms. Northerly flow will also continue to usher in enough moisture to perhaps support some very light snow showers in the high terrain during the weekend timeframe but will ultimately remain inconsequential. Flow aloft will turn zonal come Sunday, allowing temperatures to drastically warm into the 50s and low 60s across the lower elevations for much of the week. Weak disturbances will bring chances for more light, showery precipitation mainly for the central and eastern mid to high elevations throughout the week. The zonal regime will also lend to breezy surface winds for the entirety of the week with winds becoming near-advisory to advisory-level.

VFR conditions generally expected at eastern Idaho terminals through the period. The sole wrinkle in this is the potential for fog which is shown by some hi-res models. That being said, confidence is low as models don't seem to have a good handle on where the bulk of the moisture fell yesterday. KPIH would be the most logical location for it and to a lesser extent, perhaps KIDA. At least included mention in the latest forecast at these sites although kept things VFR as confidence is quite low. Not expecting it to be much of a concern at KSUN, KBYI or KDIJ although KDIJ can certainly be tricky sometimes in situations like this. Winds are much lighter throughout the region today, generally 10-15 kts or less, and this should continue through the period. Occasionally higher gusts around KBYI are possible. No precipitation is expected over the next 24 hours but clouds will begin to increase once again as we move into tomorrow late morning and afternoon but CIGs will be high enough to keep things VFR.
