Derby weekend is here... and it will be a cool one for sure. We'll see mostly to partly cloudy skies Friday with a few showers possible, mainly in the morning, and below normal highs in the low to mid 60s. Saturday looks cooler, but sunnier with a northwest wind keeping highs suppressed, in the upper 50s to low 60s. We'll wrap up the weekend with Sunday morning lows in the mid to upper 30s and patchy frost potential, but mostly sunny skies and afternoon highs around 60°.
