KEY MESSAGES

- Hazardously cold wind chills through Sunday morning as cold as minus 50.

..Extreme Cold Through Sunday

Not much has changed from what has been messaged the past few days, with current conditions evolving about as expected. As the surface high tracks to our south tonight, temperatures will be driven down into the teens and 20s below zero, with a handful of locations in northwestern MN touching on -30F. Even though temperatures will be similar to last night, winds will be lighter. Therefore, wind chills will not bottom out quite as low, with values of -50 in the north and -35 in the south. As the high pushes further east on Saturday, we will be left in a weak WAA regime. This will cause temperatures to rise, albeit since we are starting at such a low point, highs will still be below zero. There will be a break in the "extreme" cold during the afternoon/early evening hours, where wind chills climb above warning criteria. This reprieve will be short lived, as another high tracks south out of Canada. As it does so, it will bring temperatures back down Saturday night into Sunday morning, driving wind chills back into the -30 to -50 range, coldest north, warmest south.

No headline changes were made at this time. The best way to tell the story of cold through the weekend is maintaining simpler headlines through Sunday morning. There will likely need to be some cold weather headlines issued for late Sunday into early Monday, but it will NOT be as cold as we saw yesterday afternoon into this morning. Future shifts will determine how to proceed with headlines beyond noon on Sunday.
