A pattern change to warmer weather is set to begin this weekend, with an extended period of above freezing temperatures likely much of next week across southern Manitoba. The warmer temperatures will start eroding the lingering winter snowpack still intact over much of southern Manitoba, including the Red River valley where current snowdepths range from 25 to 40 cm. However, some places in southern Manitoba have already lost much of their snowpack especially over SW Manitoba along the SK border, and parts of the Pembina river valley around Morden. These places will see the warmest temperatures this weekend, with values likely climbing into the double digits Sunday. Here in snowcovered Winnipeg and Red River valley, temperatures will not be quite as warm.. with highs Sunday in the 3 to 5C range. Note also that today will be see extensive cloud cover in the RRV as low level moisture gets trapped under a strong inversion (with warm air aloft overriding cold air at the surface) along with brisk southerly winds. Not the most pleasant day even though temperatures will be climbing to near zero today.
Mild temperatures will continue Monday, but a low pressure area tracking though the Dakotas will bring some springtime rain, yes rain, to southern MB Monday afternoon and evening. Slightly cooler weather is on tap Tuesday and Wednesday before temperatures climb above freezing again for the balance of next week.
