Scattered Showers and thunderstorms possible tonight, best chance across central Wisconsin.
Thunderstorm profiles will be high based and thermodynamics on the weak side (AOB 1500 SBCAPE). With 50kt of bulk shear - mostly unidirectional but some veering - will be enough for organized updrafts. Severe weather is not expected due to weak thermos but I wouldn't be surprised if something did occur. Cannot rule out a strong storm or two with gusty winds or hail.
Temps will be near average this week with rain chances increasing Weds thru Friday.
