The Super Bowl delivered plenty of thrills and spills Sunday with the New England Patriots beating the Seattle Seahawks 28-24 in a down-to-the-wire finish. There will be plenty of Super Bowl coverage, including replays of the last-second interception by rookie cornerback Malcolm Butler, commercial rankings and critiques of Katy Perry's halftime spectacle, but that's not the only developing story to start the week. Here are a few more stories you should be following today.

A new winter storm is expected to hit the Northeast Monday, Reuters reported. It's already brought plenty of snow to the Midwest, including a foot of snow in Chicago, and is expected to bring several inches to the Northeast. New York City could get around 3 to 6 inches while Boston could see up to a foot of snow. The latest round of snow follows last week's much-hyped winter storm that failed to live up to expectations in NYC but dumped more than two feet of snow on Boston. "This will be a potent winter storm from the Ohio Valley to New England, and numerous winter storm warnings are in effect from eastern Ohio to Maine, where snowfall amounts on the order of 6 to 12 inches can be expected, with locally higher amounts. Bitterly cold weather will settle in behind this system from the Upper Midwest to New England," reads the National Weather Service's latest update.

Groundhog Day 2015

Punxsutawney Phil stepped out of his burrow on Groundhog Day and saw his shadow Monday morning in the annual ritual in the Pennsylvania town. Based on the tradition, that means we can expect another six weeks of winter weather. If you're already over the winter, you can choose to go with Staten Island Chuck's prediction of an early spring. Chuck has a better track record, up to 80 percent accuracy, compared to around 39 percent for Phil.

Most toddler dinners, around seven out of 10 on the market, had too much salt while snacks, pastries and cereal bars had too much sugar.

President Barack Obama Weighs In On Vaccinations

As the measles outbreak spread to some 30 states, President Barack Obama appeared on NBC's "Today" show and said children should be vaccinated. "A major success of our civilization [is] the ability to prevent diseases that in the past have devastated folks, and measles is preventable," Obama said, noting his stance is backed by science. The New York Times has a lengthy article detailing the discredited study that started the anti-vaccination movement.
