Will the U.S. continue to thaw out in March?

Spring can't come soon enough.

At least that's what the eastern half of the country seems to be saying. After all, February's temperatures were the top 10 coldest for most of the Midwest, all of the Northeast, and even parts of the South.

Even as recent as last week, temperatures were frigid east of the Rockies. Kentucky issued a state of emergency for the second week in a row because of significant snowfall. And the Great Lakes were 88 percent frozen, the second most ice cover — only to last year's polar vortex — in the last 20 years.

Now, snow and ice are melting and temperatures are feeling more like Spring. Most of the country is experiencing warmer than average temperatures today, which feels all that much warmer since it's been so much colder than usual as of late.

It also looks like this trend will continue through at least next week.

So why the sudden temperature swing? The huge high pressure system that's been camped off the West Coast has finally broken down, allowing the jet stream to straighten out and return north.

With the warmer, more spring-like temperatures, it's only a matter of time before we see our first major severe weather outbreak.
