As snow begins to cover the Texas Panhandle amid the polar vortex, here's what the state can expect as weather conditions begin to shift.

A winter storm that is expected to begin in Texas next week could end up bringing snow and ice to parts of Florida.

DALLAS - Most of the nation is in good shape on Wednesday and will be warmer on Thursday. The arctic air is coming, but not yet. The center of the polar vortex is not coming to Texas, but it will funnel cold air down from the North Police, so it will keep us well below average next week.

A blast of Arctic air is set to cover much of the United States with temperatures below freezing starting on Friday and into next week, impacting millions of Americans in nearly all of the contiguous states.

Some areas of the U.S. may see temperatures as low as -20 or -30 degrees early next week as arctic air from Siberia rolls in.

A winter storm that is expected to begin in Texas next week could end up bringing snow and ice to parts of Florida, but the forecast is far from a lock.

A winter storm is sweeping into the Austin area on Monday evening and continuing into Tuesday morning, the National Weather Service said.

A dangerous and potentially life-threatening stretch of cold weather has much of the U.S. on alert as a lobe of the polar vortex invades the nation and sends temperatures tumbling to levels not seen in years.

State Climatologist Jay Grymes said there could be lows of 20 degrees across the state between Monday and Wednesday and the National Weather Service (NWS) has said Baton Rouge could see its first snowfall in seven years. Newsweek has contacted the Louisiana Governor's Office of Homeland Security and Emergency Preparedness for comment.
