The Twin Cities metro is not under either an advisory or warning — but this weekend could still be quite frosty.

"The first widespread frost of the season is possible tonight [Friday into Saturday]," the National Weather Service says in a Hazardous Weather Outlook, "as temperatures fall into the mid 30s for areas outside of the Twin Cities metro."
