Area Forecast Discussion National Weather Service Boise ID 156 PM MST Wed Feb 24 2021

SHORT TERM. Tonight through Saturday . A winter storm is headed our way and winter weather warnings and advisories have been issued. After an upper level ridge moves over us tonight, a potent storm embedded in fast northwest flow aloft will begin to bring snow to northern sections of the area late Thu afternoon. A Winter Storm Warning for snow and blowing snow begins at 5 pm MST tomorrow for the West-Central Mountains. Snow will be relatively light for the first 12 hours or so of the warning, but increasing winds will take what snow does fall and blow it across the roads, leading to dangerous travel conditions. Snow will increase Thursday night and especially Friday, and additional warnings for snow and blowing snow go into effect for Baker County, the Upper Weiser River Basin, and the Boise Mountains at 5 am MST Friday. Also, a Winter Weather Advisory for snow and blowing snow begins at the same time for the Owyhees, Southwest Highlands, and southern Twin Falls County. The most significant upper level impulse embedded in the northwest flow aloft will pass through Friday into Friday evening, bringing the heaviest snow and strongest winds. A separate wind advisory will likely be needed for a large portion of the area for Friday, but is not being issued at this time as we await further convergence in model solutions on where the strongest winds will occur. Snow will begin to taper off in the north early Saturday morning, and the warnings in the north are presently set to end at 5 am Saturday. In the south, the advisories continue until 5 pm MST Saturday, as winds there will be strong enough to keep the blowing snow going through the day, even as only minor additional snow falls from the sky. Total snowfall accumulations through Saturday should range from 1 to 2 feet in the mountains above around 6000 ft, with 2 to 3 inches expected at Baker City, around a foot in McCall, and 4 to 8 inches in the lower elevation towns in mountainous areas (such as Idaho City, Council, Prairie, and Garden Valley). Temps will be below normal through the period, as you might expect during a winter storm. As always, the exact snow amounts and wind speeds in the forecast will change slightly as we move closer in time to the onset of the storm, but we are confident that this will cause serious travel issues. Please plan accordingly if you must travel in the warning/advisory areas Thursday evening through Saturday.

LONG TERM. Saturday night through Wednesday . Lingering snow showers will remain through Saturday evening as the upper level trough exits the region. We will see a brief break on Sunday as an upper level ridge builds offshore. Disagreement among the models leaves confidence low on Monday, but a chance of snow showers does exist with a few models showing a trough passing through. Tuesday and Wednesday are still on track to remain dry. Temperatures remain below normal for the period.

AVIATION. Mainly VFR. Surface winds, northwesterly 10 to 15kt with afternoon gusts of 20 to 25kt. Winds aloft at 10k feet MSL, northerly 10 to 15kt.

BOI WATCHES/WARNINGS/ADVISORIES. ID . Winter Storm Warning from 5 AM Friday to 5 AM MST Saturday IDZ013-033. Winter Weather Advisory from 11 AM Friday to 5 PM MST Saturday IDZ015-029-030.

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.
