Aviation Forecast Discussion

.AVIATION... 12Z TAFS: VFR conditions will continue across the region. A passing weather system will trigger scattered showers and isolated thunderstorms over the mountains of northern Washington, Idaho Panhandle, and down around the Lewiston area. The NBM shows a 30% chance of thunderstorms for KLWS, so a PROB30 group is included from 20z-02z. Main concerns with thunderstorms will be gusty outflow winds, with variable gusts of 20-30 kts possible. After 02-06Z the threat of showers/t-storms wanes throughout the region. FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: There is high confidence for VFR conditions except under heavier showers or thunderstorms where brief MVFR visibilities are possible. A few showers may also slip north toward the GEG/SFF/COE area later this afternoon and evening, but confidence is low, at less than 15%. ----------------------- 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:/weather.gov/otx/avndashboard &&
