We're tracking a nice but gradual warm up that begins on Derby Day tomorrow. Tonight will be chilly again with low temps falling into the low 40s by morning under partly cloudy skies. Our Saturday will feature a little more sunshine than today - and some warmer temperatures too. Partly sunny skies are expected along with a minimal afternoon pop up shower chance. High temps will climb up to around 70. We'll add a couple more degrees on Sunday with highs eventually back near 80 by Wednesday.
