The pattern has been incredibly consistent for several weeks now with a very deep trough in the jet stream in eastern North America and a very large ridge over the western continent. This can be seen in the image directly below: (Manitoba is highlighted in yellow) (this is a map from yesterday evening and is by ENVIRONMENT CANADA)
|Approximate location of jet stream yesterday evening. Manitoba is highlighted in yellow. Highly amplified jet stream.|
This highly amplified jet stream has been bringing some interesting anomalies. Parts of the Yukon is warmer than Florida this morning. Haines Junction Yukon was sitting at 13°C at 6 am local time this morning which was warmer than Orlando Florida's 7°C.
This pattern has maintained a northerly-northwesterly flow over Manitoba lately and has put us in a prime position for many clipper systems.
Another round of snow is expected tonight. However, this is actually associated with a system all the way up in Hudson Bay. A general 3-5 cm is expected in the Winnipeg area, with highest amounts most likely to our east. The biggest story will be the wind with blowing snow expected this evening.
Some more snow is expected again tomorrow, albeit lighter with a couple cm not out of the question. Strong winds in the afternoon will create blowing snow in open areas again.
A clipper system is then expected on Saturday night with another 2-5 cm not out of the question. However, this will depend on the exact track of the system. Very strong winds on Sunday will likely create another blowing snow situation.
At this point, a very cold start to the work week is expected next week and there is still no sign of a prolonged period of above normal temperatures. The general ups and downs are expected to continue.
