Heat rebuilding across southern Prairies

After a couple of days reprieve, hot weather is again returning to much of the southern Prairies this weekend, including southern MB. Temperatures in southern MB will hit the 30c mark again today with even hotter temperatures of 35c for Sunday into Tuesday. Fortunately, it looks like the humidity levels will not be as oppressive as last week's heat wave which saw dewpoints climb into the mid to upper twenties. Dewpoints over the next few days should be in the more moderate 15-20c range which combined with 35c temperatures will still make for uncomfortable conditions, with afternoon humidex readings in the 40-43c range. However, local areas such as the western Red River valley may once again see higher humidex values due to humidity input from crops (especially corn)
