Southern Manitoba

(south of 53°)

     

Discussion :

  
Dry surface and upper ridging both from the southeast results in warming temperatures and widespread cross-over conditions today. Winds in southern agricultural areas and extending southeast into the Sprague area will be moderate and gusty today mainly from the east, raising the fire hazards further. A stacked low approaches from the south overnight bringing much needed rain to far southern areas starting overnight, also reaching up to Brandon and across to Bissett tomorrow as the low slips under MB into Minnesota. The southeast corner is expecting up to 10 mm of rain in total, down to only a few mm at the northern edge around Bissett, Gimli and Brandon areas. Locations further north of the rain (Swan River, northern Interlake, Berens River) will be warm and windy tomorrow with possible cross-over conditions.

Discussion :

  
Conditions are warm and dry today with expected widespread cross-overs, due to surface and upper ridging from the southeast. Winds are also light in central MB under the middle of the ridge. Tomorrow sees an arctic ridge start to push down into northern MB while a low moves under the province, bringing continued warm and dry conditions with cross-overs to southern portions of central MB, this time accompanied by moderate and gusty winds, while northern areas cool off.
