Wind chills in mid -50's for southern Manitoba Wed morning

NAM model trend for surface temperatures (in C) for Wednesday morning

We are showing you the NAM-12km resolution model depiction of possible surface temperatures (in Celsius) on Wednesday morning, but it is one of the extreme cases. However, the GFS model depicts temperatures in the -40C with wind chills exceeding -50 for southern Manitoba. Therefore, keep in mind that the depictions in this post are one possible outcome out of many. Above is the way the model has been trending (its different "runs"), which shows some consistency that an extremely cold airmass will be in place for Manitoba.
