895 FXUS66 KOTX 181237 AFDOTX Area Forecast Discussion National Weather Service Spokane WA 437 AM PST Wed Feb 18 2026 .KEY MESSAGES... - Bands of snow through this morning bringing winter travel conditions to areas of Eastern WA and North Idaho. Be prepared for a slow Wednesday morning commute. - Periodic hit and miss snow showers Thursday and Friday. - Additional preciptiation chances Sunday into next week. && .SYNOPSIS... An active weather pattern will continue through the work week. Light to locally heavy snow accumulations in areas of North Idaho and Eastern Washington by Wednesday. Snow showers will continue on and off Thursday into Friday. Temperatures moderate over the weekend with additional chances for mountain snow and mix of rain and snow in the lowlands next week. && .DISCUSSION... Today through Friday: Round two of convective snow bands are starting to move through the forecast area from the south, which will impact the morning commute. Due to steep low level lapse rates (8-9 degC/km) combined with very cold air aloft, these snow bands can bring short lived, moderate impacts to areas they move over. There are currently Winter Weather Advisories out for the eastern third of Washington and the Idaho Panhandle apart from the Northeast Mountains and Northern Panhandle. While isolated, moderate impacts associated with convective snow bands are lowered visibility, snowfall rates of 1-2 inches per hour, and up to 5 inches of snowfall in isolated areas. Travelers this morning should be prepared for a slower commute. Overall snow totals will vary greatly due to these bands, but probabilistic guidance shows a 30-50% chance for Spokane down to Pullman seeing at least 1 inch of snow, and a 30- 40% chance for Lookout Pass to see four inches of snow or more. Troughing will remain over the area through Friday, resulting in light showers through the same area this afternoon through Thursday morning, and then again Thursday night into Friday morning. Cold air aloft and steep lapse rates remain over the forecast area through Thursday afternoon, but lower in intensity each day. Still, the potential for convective snow bands and their associated impacts continues through Friday morning. Be prepared for wintry road conditions and for morning/evening commutes to take longer than normal. These snow showers will yield little overall accumulation, with only a 20-60% chance of an inch of snow or more. Saturday through Monday: On Saturday, an upper level low drops down off the Canadian coast. While clusters show anomalously low heights associated with this trough, 85% of clusters have the trough too far west for us to see any significant impacts. As a ridge builds with its axis centered over Montana, the accompanying surface high and low will form a tight pressure gradient on Sunday morning, bringing concerns for gusty winds. While long term models show higher gusts (35-45mph) confined to the Cascades, they show the Basin seeing gusts up to 25 mph. The positioning of the upper level low will usher in warmer than normal, southerly flow to the forecast area, which will allow temperatures to moderate back to near normal. This will also raise snow levels, favoring more mixed precipitation in the lowlands, which could bring travel impacts. The CPC`s 6-10 Day Outlook reflects this, showing chances for near normal temperatures and above normal precipitation. With this pattern, expect an unsettled weekend with continued winter driving conditions along mountain passes. /AS && .AVIATION... 12Z TAFS: The overnight system is currently over the Idaho Panhandle and will continue to shift East through 21-00Z with light snow. IFR to MVFR will start the period for GEG-SFF-COE- PUW. With the exiting system, conditions at these sites are expected to improve VFR. Low level ceilings is lower the chance of dense fog developing at these sites. Any breaks could bring IFR vis. Drier air will keep MWH-EAT at VFR through the period. The same is expected for LWS. GEG has a high chance for IFR vis tonight with developing fog over the West Plains. FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: Moderate confidence on timing of improving ceilings. Moderate to high confidence in VFR/MVFR ceilings for LWS, MWH, and EAT. Moderate confidence on the IFR conditions for GEG. /JDC ----------------------- Confidence descriptors: Low - Less than a 30 percent chance Moderate - 30 to 70 percent chance High - Greater than a 70 percent chance For additional probabilistic information for NWS Spokane airports,please refer to the Aviation Dashboard on our webpage: https:/www.weather.gov/otx/avndashboard && .Preliminary Point Temps/PoPs...
