I have to agree with these guys: prob the battery. I know when it's cold out, it's harder for a batt to start the car... cuz that's what I'm experiencing right now (damn PA winters!).
The best thing to do is to let your car run for 10-15 mins in the morning: this warms up the car to operating tempurature, helps melt off the ice and snow, and most importantly, charges your batt so you don't have the problem you are experiencing...
Good luck, hope you can get someone to jump-start for ya again!
