Area Forecast Discussion National Weather Service Boise ID 827 PM MDT Fri Oct 15 2021

DISCUSSION. Dry conditions noted across the forecast area, with a few pockets of gusty wind during the afternoon hours. Dry and mild conditions continue on Saturday as the ridge axis moves through the area. Increasing southwest flow Sunday as the next trough works to move inland across the Pacific Northwest. Guidance continues to suggest the system moving over the forecast area as early as Sunday evening, with increased shower coverage on Monday as the system closes off and moves along the Idaho/Nevada border. Variations in model guidance remain, which will influence timing and precipitation coverage. No changes planned to immediate term forecast.

AVIATION. VFR. Mostly clear. Surface winds: SE 5-10 kts. Winds aloft at 10k ft MSL: W 20-30 kts becoming SW 15-25 kts by 18z/Sat.

Sunday Outlook . VFR with mostly clear skies through Sunday morning. Increasing clouds and southwest winds Sunday afternoon ahead of a Pacific cold front. Gusty W-NW winds Sunday night through Monday morning following the front, with MVFR/IFR conditions and mountain obscuration in rain and snow showers.

PREV DISCUSSION. SHORT TERM . Tonight through Sunday night . A relatively flat upper level ridge will pass overhead tonight, leading to mostly clear skies and typical diurnal winds. Southwest flow aloft will develop tomorrow, giving us a warmer day with moderate east to southeast winds through the Snake Plain and Baker Valley. An upper level trough will move toward the CWA Sunday and Sunday night, spreading showers from west to east. Showers will enter eastern Oregon Sunday evening and southwest Idaho after midnight. Snow levels will be high (6k-7k ft), so light snow will only accumulate above that level. Temps will warm to around 5 degrees above normal Saturday, then warm another degree or two Sunday. On Sunday, moderate south to southwest winds will develop across southeast Oregon and Owyhee and southern Twin Falls counties, while southeast winds 10-20 mph will once again cover the Snake Plain and Baker Valley.

LONG TERM . Monday through Friday . A closed upper-level low will enter the region on Monday and increase shower activity, with snow levels dropping to around 5000-6000 ft MSL. There is some uncertainty on where this system will track. But daytime temperatures will lower to around 10 degrees below normal. Temperatures may be cooler with lower snow levels if the center of the system tracks overhead. Warmer temperatures and dry conditions by Tuesday as the system moves east with upper level ridging moving in. Temperatures will be around 5-10 degrees above normal for the remainder of the extended period under southwest flow aloft.
