Editor's note: Much of the text below remains the same as it was on Wednesday, but the list has been updated to include Thursday and Friday cancellations.

Residents in Centreville woke up to a grey, slushy day today, but that should soon change to a snowstorm that could bring up to 10 inches of snow tonight. 

The National Weather Service has issued a winter storm warning, meaning that travel tonight will be "very hazardous or impossible." Several local churches, schools, and other organizations have already posted cancellations of their events.

If you know of a cancellation for today or tomorrow, email mary.stachyra@patch.com or simply write in the comments below, and we'll add it to the list. This list will be updated throughout today and tomorrow, as we get word of new closings.
