WeatherExtreme Forecast Discussion 8/3/2017 1440Z

Once again there are problems with the local WRF model, so this morning’s forecast is based on ECMWF, GFS, SkySight, RAOB and satellite. Thursday should be much improved for flying with a few scattered low clouds in the morning in El Calafate, becoming mostly clear by afternoon. Surface winds out of the west 10-15 kts gusting to 30. Winds aloft west-southwesterly 50-80 kts above FL100. Moderate wave will be present with vertical velocities 1000-1500 fpm, diminishing above FL200. Orographic precipitation and low clouds will be present west of the ridge line.
