Summit Forecast – Monday, August 12, 2013

A slight ridge of high pressure will be pushed out of the picture by an approaching cold front tonight and tomorrow, resulting in steadily deteriorating weather conditions over the forecast period. Today will commence under primarily clear skies across the higher summits, with relatively light winds and temperatures quickly rising into the lower 50s. Thereafter, patches of fog will begin to enter the picture as moisture streams in ahead of the impending frontal boundary. Fog will continue to thicken into the overnight hours, with a chance of showers and perhaps a rumble of thunder entering the forecast by morning. The risk of precipitation will increase tomorrow as the front charges through, which will also prompt wind speeds to ramp up, particularly within any thunderstorms that may develop.
