.DISCUSSION...



A cold front will progress across southern Wisconsin this morning,

bringing a quick round of light flurries/snow showers. 20 foot 

winds will shift out of the north behind the departed front, 

quickly becoming gusty. Expect sustained readings between 10-15 

MPH through this afternoon, with gusts up to 25 MPH possible. 

Encouraged by the northerly wind shift, much drier air will work 

into the vicinity this morning, resulting in minimum relative 

humidities in the middle 20 percents this afternoon. Minimums 

could briefly fall into the lower 20 percents if dew points trend

lower than currently forecast. Additional scattered snow showers 

are possible this afternoon, with no accumulations anticipated. 20

foot winds will taper tonight, with relative humidities 

recovering to near 70 percent locally. North-northwest 20 foot

winds will be lighter on Tuesday as high pressure crosses the

region. Passage of the high will result in even drier conditions,

with minimum relative humidities falling into the middle 20

percents during the afternoon. Minimums could briefly fall as low

as the upper teens if temperatures trend warmer than currently

forecast.
