For this forecast period, the weather models have been bouncing back and forth between a return to cold weather after a brief mid-week warmup or a return to the mild weather pattern we saw during much of December. The models have been slowly converging towards the milder solutions, but at this point confidence in the second half of this forecast period is low.

The weather for this forecast period will be largely controlled by a large, stationary area of low pressure in the Gulf of Alaska. This has been sending wave after wave over energy into coastal B.C. This will result in a predominately west to southwesterly flow across the Prairies—meaning a continuation of mild temperatures as Pacific air dominates.

To start this forecast period, the strong area of low pressure that tracked through the eastern Prairies is now over Hudson Bay. The rotation around this low is opening the door for a strong, very cold Arctic high to build southwards into the eastern Prairies. This looks to bring some of the coldest temperatures so far this winter to eastern Saskatchewan and western Manitoba. The good news is that it doesn't look like the cold air will stick around long.
