A few places may reach 60 degrees, but most highs will be in the mid and upper 50s. A clear, cold night will follow as winds turn calm, allowing overnight lows to range through the 30s.

Admin Note: After the cold mornings this weekend, most of the area has seen their growing season end in practicality. Officially, many areas were already considered out of the growing season, which is why the NWS did not issue frost of freeze alerts over the weekend except along the Lake Ontario shore. I will now be following suit and will no longer be discussing frost and freeze issues. As always, if you have questions specific to your situation, just Ask Drew!
