I'm leaving this:
For this:
THE NATIONAL WEATHER SERVICE IN CHICAGO HAS ISSUED A WINTER
WEATHER ADVISORY FOR SNOW...WHICH IS IN EFFECT UNTIL 9 PM CST
THIS EVENING.
At least I'll get there earlier than planned. I tried to get on the 11:30, but because the 7:30 had left at 9:30, and the 9:45 was delayed, they put me on the 9:45 which actually leaves (we hope) at 11. So instead of 7 hours at home before traveling again tomorrow, I get 9. I hope.
Update: Well, the 9:45 actually now leaves at 1pm, in theory, leaving me almost exactly no better off than the original plan. We'll see.
