I have a flight tomorrow and it is suppose to be a "steady rain" with winds gusting up to 25 mph. Will my flight be canceled? Do they still take off in "Steady Rain?" It's an 8:30 flight so early in morning. It's going east where the weather is fine. Please help me with as much info as possible. I'm worried it will be canceled and I will be stuck on Xmas eve...

It's on USAIRWAYS airbus A321...from SFO to PHL

Flight is 8:30 arriving PHL at 4:30....Thinking plane isn't coming from anywhere and am hoping it will be at the gate waiting...thoughts?
