Aviation Forecast Discussion

.AVIATION... 18Z TAFs: After some morning fog, all TAFs but KMWH/KEAT have improved to VFR status and are expected to stay that way until around 09Z. This is when the upcoming system will move in, bringing rain to each site. By 17Z, LIFR ceilings are anticipated to return to KGEG/KCOE/KMWH. KMWH/KEAT is anticipated to have LIFR/IFR conditions through 22Z, then improve. Around 09Z, ceilings will lower to MVFR/IFR as rain moves in. .FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: Model guidance getting a better hold on the incoming rain. High to moderate confidence in ceilings being at VFR until the rain moves through around 09Z. Moderate confidence in timing of rain. Low to moderate confidence in timing for ceilings dropping below IFR at KMWH. /AS ----------------------- 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 &&
