Does the announcement mean we get weather waivers to change our flights without penalty? I'm scheduled through IAH with a 730p arrival tomorrow and a short 1hr layover. I stupidly paid a B fare to snag upgrades on a flight to SEA that I originally thought looked bleak (until a few people canceled).

I'd rather re-route through EWR and snag the last couple F seats on my selected flights since I already have the B fare.
