Tonight 

High pressure, currently located over the Northern and Central
Plains, will build quickly east across the area tonight. As 
this occurs, the surface pressure gradient will slacken. The
combination of light winds and clear skies will result is strong
radiative cooling. As typical with the NBM, it looked too warm 
in central Wisconsin so blended in some MOS. Low temperatures 
will range the mid-20s to lower 30s. There may be even a few 
locations in the lower 20s in central Wisconsin.

Weekend

The surface high pressure area will shift east into the Great
Lakes and into the Mid-Atlantic this weekend. As this occurs,
the winds will become southerly and increase into the 10 to 20
mph. High temperatures will warm into the mid- and upper 50s on
Saturday and into the lower and mid-60s on Sunday.

Monday through Friday 

A 500 mb ridge will build across the region early in the week
and it will keep the area dry and unseasonably warm through the
remainder of the week. High temperatures will be mainly in the 
60s through Wednesday and around 70s Thursday and Friday. Low 
temperatures in the 30s and 40s through Wednesday and 40s and 
50s Thursday and Friday.
