A welcome break from the cold of the past couple of weeks will be on the way this week as a persistent Arctic airmass over southern MB eases its grip. As a result, temperatures will be rising to more normal values for this time of year, with highs around minus 10C much of the upcoming week, as opposed to the frigid minus 20 and minus 30 readings of the past little while. In its place will be a moderating flow of air from the west which will be characterized by occasional clipper systems passing through southern Manitoba this week, each bringing a round of snow. The first clipper is expected Monday, with snow arriving in Winnipeg and the RRV sometime in the afternoon and lasting into the evening. About 2-5 cm is possible with this system which will likely impact the Monday drive home. The next clipper is forecast for Wednesday with another 5 cm possible, with higher amounts of 5-10 cm predicted by some models. Additional flurry activity is possible by the weekend along with a push of milder air that will likely give us a period of above normal temperatures for a few days.
JANUARY 2013 stats: January 2013 ended up with a mean monthly temperature of -16.7C at YWG airport, just slightly (0.3C) below the 1981-2010 January normal of -16.4C. A mild start to the month boosted the overall average that compensated for a very cold finish. In fact, the month was actually 1.1C ABOVE normal if the older 1971-2000 normals were used (January mean of -17.8C) This shows how mild Januarys have become over the past decade or so. Snowfall in January (as measured at my station) was 40.2 cm, bringing the seasonal total to 115 cm though January 31st. Normal seasonal snowfall for Winnipeg is 110 cm. Last year, we had a total snowfall of 80 cm for the entire winter.
