Windy & Mild Today, Sharply Colder & Dry Monday!
Strong low pressure has moved north into southern Ontario Canada. As you can see in the graphic below, an impressive cold front trails from the low and will be the focus for widespread rain and a few thunderstorms as it moves through the Badgerland today into this evening:
Ahead of the front, much of southern Wisconsin will enjoy another mild afternoon, but this will be tempered by very windy conditions. In fact, a Wind Advisory has been posted for much of south central and southeast Wisconsin, extending south and east into Illinois, Indiana and Lower Michigan. Southerly winds could gust to as high as 45 mph!
The cold front will bring widespread rain and maybe a rumble of thunder as it moves through. The rain will continue into the evening hours, before tapering off by or shortly after midnight. Much colder air moving into the area may allow for light snow showers to mix in with the rain just before it ends. No accumulations are expected.
High Temperatures on Monday will drop about 30 degrees compared to highs this afternoon! The two images below highlight this contrast:
The image below is the accumulated precipitation analysis, ending Monday morning.
High Pressure will build in by Monday and the current long range forecast indicates that dry weather and high pressure will hold strong through early next week!
