The cyclonic circulation around a surface low pressure system surported by a 500hPa trought is currently located over the Northern border between Alberta and Manitoba. The associate driven northwesterly flow may bring precipitation over our study area. Due to the orogrpahy and the warm expected temperatures, intermittent rain episodes are forecasted for today for the eastern side of the divide.
A major low pressure system is currently in the Pacific Ocean. There is currently a ridge between our study area and this system, specifically on the west coast of British Columbia. The long-term models suggest an eastward shift of this synoptic pattern, causing our study area to be affected by this depression over the next week. A follow-up of the short-term models will make it possible to bring more precision on the precipitation events that are expected, considering that snow could occure.
