We did see some record-breaking temperatures in some regions of Manitoba last week, but not where most people were expecting them. Central and northern regions saw a strong ridge of high pressure dominate the weather and under the sunshine many locations saw highs in the +5 to +10C range. Southern regions had more clouds and fog to deal with, keeping temperatures down.

The forecasted Colorado low for late last weekend didn’t really get going on time. Instead it is forecast to push eastward during the middle of this week. The track of this storm should keep most of the precipitation south of Manitoba, with only some light rain or freezing rain expected over southern and eastern regions. A trailing trough of low pressure behind this low could keep southern regions cloudy for most of the week.

High pressure building in from the North should keep northern and central regions sunny for most of this week with continuing mild temperatures. The question is whether this high will be able to push the clouds out of the southern regions by the weekend.

This battle between the northern high and the trough of low pressure to our south looks as if it might last right through the weekend and into next week. Looking a little further ahead, the models are showing a bit of a cooldown late next week, as cooler arctic air tries to push southward.

Usual temperature range for this period: Highs: -10 to +3C. Lows: -24 to -6C.

Probability of precipitation falling as snow: 90 per cent.
