Back-to-back powerful Pacific storm systems to impact the Pacific Northwest and northern California through the end of this week with heavy rain, flooding, strong winds, and higher elevation mountain snow. A strong, long-duration atmospheric river will accompany the Pacific storms, bringing excessive rainfall and flash flooding to southwest Oregon and northwest California through the week. Read More >
.AVIATION... 06Z TAFS: Widespread light precipitation will continue overnight into Thursday morning. Precipitation is expected to fall as wet snow at airports in the northern mountain valleys that includes Colville (CQV), Sandpoint (SZT), and Bonners Ferry (65S). Around Deer Park (DEW) to across the Spokane/Coeur d'Alene corridor and points southward, precipitation will fall as rain. Rain without good upslope with winds from the east is expected to keep fog from forming, but low stratus will result in IFR to MVFR conditions across northeast Washington into the Idaho Panhandle. Rain tapering off late tonight around KOMK-KEAT-KEPH-KMWH and a moist boundary layer is more likely to result in clouds lowering and mist or fog present with low IFR conditions possible. A weak shortwave disturbance passing across Thursday afternoon should produce more rain out into the basin and will see fog lifting more into low stratus deck at this time; however, widespread IFR to MVFR conditions is expected through the day Thursday aside from at the Lewiston Airport (LWS) where VFR conditions are expected to prevail. FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: Confidence is high for the area to remain under a stratus deck with MVFR conditions at KGEG-KSFF-KCOE. This will also come with rain overnight. Low confidence on ceiling heights or dense fog development with probability of less than half a mile below 20% around KEAT and KMWH. /SVH ----------------------- 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 &&
