Where do you see that? I can't find a good CWG update, Accuweather and Weather.com has storms all night until midnight.
...including (in the latter case) forecasts of 90-100% chance of rain from 16.00 through 21.00 inclusive - I looked at CWG about a half hour ago and didn't notice an update either.
Will probably take a pass on tonight's match - really don't feel like blowing $10 return on the transit just to go sit in the drizzle all evening waiting for them to remove the tarp (especially when I have to go to work at 06.00 the next morning).
