Chilly air expected for this week, first freeze
Milwaukee has yet to experience a freezing temperature this season. On average, the first freeze in the city of Milwaukee takes place late in October on the 23rd. A number of locations have already hit the freezing mark this season. The growing season for all of southeastern Wisconsin will come to an end this week as a prolonged period of cool air is expected to be the main weather maker this week.
Cold high pressure will grab hold of the region behind several waves of cold air this week. Highs will only climb into the 40s, with even a day of 30s by this Friday. Overnight lows will almost certainly plunge into the 20s for the inland spots, and even colder by Friday morning.Computer models are even hinting at lows dropping into the teens inland by early Friday.
The models have ben flip-flopping this weekend with how cold it will be, and what kind of precipitation will be available. The European model is indicating less precipitation, but better chances of a wintry precip. for parts of the state, while the GFS is warmer with more rain and snow/mix north.
All signs point to a colder weather pattern for now!
