Forecast from FOX6 Chief Meteorologist Rob Haswell

MILWAUKEE - We're enjoying a little taste of September in October, with another stretch of mild, dry weather ahead. Patchy fog could slow down the morning commute, but sunshine should take over with highs climbing to around 70. High pressure keeps the warm and dry stuff going through Saturday, although lakeside communities will run a few degrees cooler. A cold front arrives late Saturday night into Sunday. Rain chances increase slightly Sunday night through Tuesday. That front also signals a return to more typical fall temperatures next week, with highs dropping into the 50s.
