A large Arctic ridge of high pressure will build over the Prairies today and Thursday bringing cold but dry conditions to southern MB over the next few days. The exception will be over and south of the MB lakes where some lake effect snow is possible today into Thursday. Elsewhere conditions will be dry with generally clear skies tonight through Friday. Temperatures will be several degrees below normal for mid November with lows in the minus 15 to minus 20 range and highs around minus 10. A moderating trend is expected over the weekend as a southerly flow develops ahead of another Pacific disturbance tracking across the Prairies. This system may bring some snow over southern MB by the end of the weekend.
