The latest northeast Wisconsin weather forecast from Storm Team 5…. Another cool October morning out there as temperatures start in the upper 20s in the north, to very low 40s in the Fox Valley. We will have one more night ahead this week where temperatures will get chilly overnight, and patchy frost is possible north/west of the Fox Cities. Plan on plenty of daytime sunshine in the near term. This weekend, our area will get our next decent rain chance moving in on Sunday.
