Aviation Forecast Discussion

.AVIATION... 00Z TAFS: The development of fog and low clouds has been retained in the TAFs for Spokane and Coeur d'Alene. Earlier in the week the HREF did a decent job generating advection fog/low clouds around Spokane, and this pattern looks similar. The HREF forecasts a 60 percent chance of visibility reductions of a mile or less for Spokane International with the highest likelihood between between 12-17z. Advection fog from south/southwest winds is most favorable at KGEG on the plateau west of town. Stratus off the deck a few hundred feet often occurs in town and toward Couer d'Alene in this scenario, sometimes after a short period of radiation fog. FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: There is moderate confidence in the development of either low clouds or fog for Spokane and Coeur d'Alene since the HREF seems to have skill at predicting low advection stratus. The height of the stratus and visibility reductions carries low confidence since the wind in the boundary layer may be sufficient to prevent fog on the ground. /GKoch ----------------------- 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 &&
