.AVIATION... 00Z TAFS: A vigorous frontal system then sweeps through tonight. Rain moving into KEAT/KEPH/KMWH by 01Z and then into far eastern Washington and the Idaho Panhandle by 02-05Z. Southeasterly surface winds will keep ceilings generally between 3-5 kft agl for KGEG/KSFF/KCOE/KPUW with brief lowering down to around 3 kft agl and MVFR conditions between 06-10Z with occluded front passage. Frontal passage will bring the potential for moderate rain intensities and brief visibility reductions as well. Modest low level wind shear ahead of the front Thursday evening then gusty westerly winds up to 25-35 kts overnight. .FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: Moderate to high confidence for MVFR conditions due to low ceilings and reduced visibility with cold front tonight between 04-10Z for KGEG/KSFF/KCOE/KPUW. JW ----------------------- 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 &&
