Standard operating procedure in South Carolina is that state government offices and universities follow the lead of the county they are in for closing down in the case of bad weather.
Yesterday (Monday) the county we're in (the one with the state capital) announced it was shutting down at noon today (Tuesday) because of potential snow. Our county has very little snow removal and even less experience driving in it. So yesterday afternoon the University announced that classes ending after that were done today too.
And then yesterday evening the governor said not so fast. State offices and universities in this county are staying open Tuesday until I tell them.
And then just a few minutes ago (a bit after 11:30am Tuesday) the governor called it and said go home at 2:30. Which means everyone will be on the road at the same time and it will take forever to get home.
[Current forecast is 10% chance at noon, 15% at 1 and 2, 40% at 3,.... 1.4" total expected. More and earlier in the neighboring county many employees working here live in.]
Update: It looks like maybe the governor didn't change his mind. The University might be trying to thread the needle by keeping the University open... but cancelling later classes and telling supervisors to be flexible.
