Rain by Tuesday.. windy and warmer by end of week
The new week will start off on a dry and mild note with sunshine and temperatures rising into the low to mid 20s. Unsettled weather however will move in overnight Monday into Tuesday with occasional rain and possible thunderstorms, along with gusty northwest winds and cooler temperatures. Models are hinting that rainfall may be heavy at times Tuesday over portions of southern Manitoba and the RRV, with 20-40 mm possible in some areas. This system is expected to clear out by Wednesday as a ridge of high pressure builds in over southern Manitoba. This will be followed by increasingly windy and warmer weather by the end of the week into the weekend as the ridge moves east and a return southerly flow sets up over southern Manitoba. Gusty south winds will allow temperatures to rise to above normal values in the mid 20s by Saturday. The autumnal equinox arrives this Friday the 23rd.
