If you haven't heard it from WPS, it isn't so...

Yes, I heard the rumors too, but no, the Worcester Public Schools have not cancelled school for Monday.
Administration and facilities are monitoring this over the course of the weekend, but they aren't going to call school unless it is necessary for safety reasons.
The easiest way to find out if school is cancelled is to watch here. In fact, if you text "follow @worcesterpublic" to 40404, you will get the Worcester Public Schools twitter feed as text messages, which means you'll get a text message when school is cancelled.
And I'll post if there is any announcement as well.
