 A hazy start to the day with mostly sunny skies turning partly cloudy as we head into the afternoon. We'll have highs in the mid to upper 80s with light winds blowing out of the north at about 5 to 10. Overnight tonight, clear skies will drop down to a low in the low 60s. And another hot one as we head into your Thursday with highs in the upper 80s. We'll be near 90 on Friday and into the low to mid 90s as we head into the upcoming weekend with heat index readings approaching 100.
