A large Arctic ridge of high pressure has built into the western Prairies this morning, bringing the coldest weather of the season so far to much of the Prairies. Temperatures of -30 to -35C were widespread over Alberta and western SK this morning, including a record breaking -37C at Edmonton International. This Arctic ridge will settle over the southern Prairies today into Tuesday, bringing well below normal temperatures over the area. Afternoon highs will only be in the minus teens to -20 range over Winnipeg over the upcoming week, while nighttime lows drop into the -25 to -30 range. Minimum temperatures of -30 to -35 are likely over southwest MB over the next few nights. Get that block heater cord out!
Meanwhile a powerful blizzard is shaping up over the central US plains today, and will bring heavy snow and strong winds through Kansas, Nebraska, Iowa and southern Minnesota tonight into Tuesday.
