Area Forecast Discussion National Weather Service Boise ID 1003 AM MDT Sat Mar 28 2020
DISCUSSION. Light snow across the West Central Mountains and into the Long Valley resulted in a quick update to the forecast this morning. Accumulation from any snow in these areas should be insignificant, and activity has already slowed since the update. Additional mountains showers possible this afternoon ahead of the approaching trough. No additional updates planned for immediate forecast.
AVIATION. VFR through this evening with isolated MVFR ceilings in the mountains. Scattered showers move into KBNO/KBKE late this evening with snow levels near 5000 ft. MVFR conditions possible before early Sunday morning in low clouds and snow showers for KBNO- KBKE-KMYL. Surface winds generally northwest to southwest at 10 kts or less becoming southeast to southwest by 29/06z. Winds aloft near 10KFT, northwest 10 to 20 kts shifting west to southwest by 28/21z then all southwest by 29/06z.
Sunday Outlook . Deteriorating conditions with periods of MVFR in rain showers and some IFR and mountain obscuration in snow and low clouds.
PREV DISCUSSION. SHORT TERM . Today through Monday night . Weak ridging over the area today will limit any shower development to the higher terrain of w-central Idaho and the e-central Oregon this afternoon. High temperatures will run 3-5 degrees warmer than yesterday with generally light westerly winds this afternoon. Clouds and showers increase over southeast Oregon Saturday night, spreading into southwest Idaho through the day Sunday as a shortwave trough tracks into the Pacific NW. Upper dynamics and instability will support thunderstorm development Sunday afternoon. At this time low-mid level winds are 25kts or less so strong wind gusts would not be expected with convective development. Cold temperatures aloft would support graupel or small hail with shower/storm development. Snow levels will rise to between 5-6kft Sunday afternoon, pushing accumulating snow above mountain valley floors. Sites above 6kft will see 1 to 4 inches through Sunday night. Showers continue on Monday, increasing in coverage through the day as another upper wave moves into the region. Placement of the upper dynamics with this system will focus heavier across the e-central Oregon and w-central Idaho mountains through Monday night. Snow levels will drop to between 4-5k feet for Monday/Monday night, bringing accumulation down to mountain valley floors. Temperatures through the period are several degrees below normal.
LONG TERM . Tuesday through Saturday . Models continue to show an active westerly flow to start off the extended period as a strong elongated upper trough pushes through the Pac Nw and into the Northern Rockies by Tuesday. This initially brings a high threat of showers to the region, which then taper off by Tuesday afternoon. Snow levels at the valley floors across the north and 4-5,000 feet generally south of the Snake River. Light snow accumulations of 1-3 inches possible in the lower valleys across the north with higher amounts in the upper elevations.
Confidence cautiously on the rise for the rest of the extended as all models now in agreement (but they have changed daily the last few days). The upper low near 40N/170E this morning, is forecast to continue to drive eastward into next week. This slowly amplifies an upper ridge over the West Coast by Wed/Thursday. This would push any threat of showers to mainly portions of Valley County. If this forecast continues to hold the next few days, above normal temperatures could be possible . especially by the end of the week and into the weekend.

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.
