Some 80 degree temps appear in this forecast as we round out September

MILWAUKEE (CBS 58)--It's almost a refusal of Mother Nature to let go of summer.  After the morning fog burns off, looks for widespread 80s for highs across southeast Wisconsin.  Keep in mind an average high for late September is in the upper 60s.  We will cool off a bit behind a weak front for Sunday.  Highs will be in the low 70s.  Then we stay in the 70s for most of this coming week.  Lows mainly in the 50s.  I don't see any big system coming through the area anytime soon.
