Springlike weather will be moving over southern MB this week as a mild Pacific airmass spreads across the Prairies. We'll get a taste of that mild weather today as a westerly wind brings in above freezing temps into southern MB and the RRV with highs of +2 or +3C. A cold front however will push through this afternoon into this evening, bringing a few rainshowers that will change over to snow by late afternoon/evening as temperatures drop below freezing. Watch for icy conditions tonight as northerly winds bring in colder air and freeze up any standing water. Monday will see increasing southerly winds develop in the afternoon and evening, bringing temperatures back towards freezing. This will set the stage for very mild conditions Tuesday and Wednesday as the peak of the warm air spreads over southern MB. Temperatures will be climbing into the +2 to +5C range over Winnipeg/RRV with +7C readings possible over the traditionally warmer downslope areas from the eastern Riding Mtns through the western RRV (Dauphin to Portage and Morden)
Attention then turn to a potential storm system that may affect southern MB for the end of the week. Long range models are showing a storm system developing over the central Plains that will be moving into Minnesota by Friday. This system will be bringing increasing north winds and colder temperatures by Friday along with the potential for accumulating snow, possibly significant over the RRV. At this point, it's too early to be more specific, but it does pose our next threat for significant snowfall. Stay tuned.
