That was a nice fall weekend; Lytton was the hot spot in BC at 24.5C yesterday, but most regions in the southern interior got into at least the high teens under a sunny sky.
Fall weather patterns move quickly and a Cold Front passing over the province today will bring a noticeable shift to breezy / cooler conditions with rain and even wet snow for higher elevations.
This mornings Satellite Image shows a Surface Low off the west coast of Vancouver Island that will encourage a trough of cool unstable air to organize in the wake of this weekend's warmer air. The coast can expect increasing cloud today with showers and gusty winds with the passing of the Front. It will take until this evening for the system to cross the Southern Interior. The cooler air being drawn in from the Northwest will drop snow levels down to around 1300m overnight. Drivers should expect accumulating snow through the Pennask and Kootenay Summits and wet snow through the lower elevation mountain highways.
Today however will still bring some sunshine with increasing cloud later in the day.
