After this morning's patchy fog burns off, look for increasing clouds from west to east throughout the day. Chances for showers and storms will then move into central and north-central Wisconsin late this afternoon, before becoming widespread overnight. Today will also be the last day of temperatures in the 70s through at least the upcoming weekend.
An active and cooler pattern will set up for the remainder of the week and weekend, bringing multiple chances of rain and isolated thunderstorms, mainly Wednesday and again late Thursday through early Friday. A few showers are also possible on Saturday before the return of some sunshine on Sunday. Well below normal temperatures are also expected for the remainder of the week and weekend with record low highs potentially in jeopardy, especially on Thursday.
