Area Forecast Discussion National Weather Service Spokane WA 955 PM PST Fri Feb 26 2021

SYNOPSIS. We still have some winter weather in the form of light snow to move through tonight into midday Saturday. The mountains and higher terrain will see some heavier snow. Quiet and somewhat warmer conditions are expected Sunday into the beginning of next week however there could be some increasing clouds and mountain snow returning again toward the middle of next week.

DISCUSSION. Light snow coverage is being re-energized in east Washington and north Idaho as a low circulation in northwest flow moves south and east through the area. The air has dried quite a bit since earlier today so we expect mainly light accumulations (around an inch) with this circulation as it slowly transits into the the Idaho Panhandle into early Saturday morning. The uplifting influence of the Panhandle terrain may accumulate snow a bit more along I-90 and Lookout pass as well as the higher terrain of the Camas Prairie later tonight into Saturday morning. On average these areas could see a solid 3 inches. If heavier showers track along I-90 there could be more snow. We'll have to watch to see how this sets up. Winter Weather Advisories for these areas will be up until 10 am tomorrow.

Farther west the Cascades continue to get heavy snow especially near Stevens Pass, Plain and even into Leavenworth. Latest guidance suggests bands of snow will sag south away from the Stevens pass area by midnight. The Winter Storm Warning for the area was extended until 1 am.

After this latest wave moves out and high pressure builds in Saturday afternoon, we should see much less shower coverage and drying roads finally. High pressure will keep the region mainly dry into the beginning of next week.

AVIATION. 00Z TAFS: More snow and snow showers will be developing over the area with KGEG-KSFF-KCOE-KPUW and KLWS experiencing MVFR to IFR conditions at times. The overall trend after 15Z Saturday is to push moisture out of region from west to east. KCOE-KPUW and likely KLWS will be the last aviation forecast sites to improve appreciably after 18Z Saturday. Westerly wind generally less than 15 KT is expected however some gusts nearing 20 in the afternoon can be expected at KEAT. High pressure will build into the region later Saturday into Sunday for over improvement in conditions. /TC

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.
