WeatherExtreme Forecast Discussion 8/26 1450Z

Front and associated low dissipates off the west coast over the next couple of days. While the surface front weakens the associated upper low and trough moves north of El Calafate Monday, turning the upper winds to a southerly direction. As the weak trough and upper low past generally north of the area on Monday and Tuesday, models are forecasting generally westerly upper level winds, however the direction will be determined by the exact path of the trough passage, and small deviations to the path could result in large swings in upper winds at El Calafate. Upper winds become briefly westerly again mid-day Wednesday with the passage of a dirty ridge over the area. Another stronger frontal system develops and comes onshore Friday, bringing rain to El Calafate in the Friday-Saturday time frame.
