According to SWR website, they are no longer planning to introduce a snow plan tomorrow, which is a change from a few hours ago:
https://www.southwesternrailway.com/plan-my-journey/live-departures-and-arrivals
The snow has definitely been a bit weird today in my neck of the woods (edge of the South West "Red" zone); anywhere theres an angle its been forming drifts and it seems to be somewhat "drier" than previously experienced snowfalls.
There is now very much a snow plan confirmed.
There is NO SERVICE on the entire West of England route (Salisbury/Exeter), between Bournemouth and Weymouth, Dorking branch, Chessington branch, or Hounslow loop services. (Weybridge/Reading via Hounslow services will run as booked.)
