The morning decision window has passed in this time zone. Tomorrow is the score to watch.
School is probably on
Pack your bag. This forecast does not suggest a closure.
Buses: 4% chance of a cancellation or delay. Higher confidence.
Biggest factor: nothing strong in the overnight window.
What should I do? Pack the school bag. Still check your board in the morning in case the buses are cancelled.
Advanced: adjust the forecast

The Thames Valley District School Board publishes its office address in London and directs families to Southwestern Ontario Student Transportation Services for bus delays and cancellations. We are not listing every county in the board's area here. Use the board's school finder for an address outside London.
The forecast uses London's high snow-tolerance profile and the suburban route setting. That tolerance reflects lake-effect snow from Lake Huron, not a published TVDSB centimetre chart. We have not seen one, and we will not invent one.
Transportation
Southwestern Ontario Student Transportation Services
The TVDSB transportation page says the board is a partner in Southwestern Ontario Student Transportation Services and that bus delay and cancellation information is on mybigyellowbus.ca. School closures remain a board announcement. Read both.
City pages
Confirm the morning decision on the board's site. This page is not an announcement, and it is not affiliated with the board.

Questions parents ask
Does this board page cover Woodstock and St. Thomas?
Only in the sense that you should use the board finder. We do not state each community from memory. London is the city page we maintain.
Who announces the closure versus the buses?
The board announces whether schools are open. The consortium site is where TVDSB says bus delays and cancellations are posted. They can differ.
