Forecast – for Mar. 17, 2011

The weather pattern looks as if it will continue to be fairly active during this forecast period. After seeing a rather strong area of low pressure push through southern and central regions late last week, which luckily brought more wind than snow, it looks like another low will move through during the middle of this week.

This low looks to be a little weaker and will take a more northerly route. Central regions will see light snow or even some showers with this system, while southern regions will see a mix of sun and clouds with only a slight chance of light snow or showers. Temperatures over southern regions should be fairly mild, with highs making it into the low single digits.

Once this system pushes by, weak high pressure will work in to start the weekend. Temperatures will cool down a little, but it is not looking like things will get too cold. All eyes then turn toward a possible storm system for late in the weekend and into early next week. The weather models show a strong Colorado low developing and slowly pushing northeast. This low, should it develop, will have the potential to bring significant amounts of precipitation to southern Manitoba, North Dakota and Minnesota. A lot can change in regard to this system, but it will definitely need watching.

Cool high pressure is then forecast to drop southward behind this storm, bringing a return to more winter-like temperatures for the middle part of next week. Looking even further ahead, the weather models hint at another strong storm system developing to our southwest late next week.

Highs:-8 to +4 C.Lows: –23 to -5 C.

Probability of precipitation falling as rain: 15 per cent.
