"Only in Buffalo," commented one man, "Can we approach 70 one day, and freezing the next."

After a weekend in the 50s, and a high of 65 late Sunday morning, the weather is turning much more seasonable and chilly for the work week.

There could be thundershowers Sunday night into Monday, and then Omday will be sunny but cold, with a high around freezing.

Snow pops back into the forecast by Wednesday.
