You probably noticed: It's really cold outside. But it's not just you.

According to the National Weather Service and meteorologist Eric Holthaus, all 50 states hit 32 degrees or lower on Tuesday.

Yep. Even Hawaii, where Mauna Kea, a dormant volcano reaching 13,800 feet above sea level, was below freezing.

This map from the National Weather Service's Twin Cities office shows you that:

Residents of the Piedmont will experience a bitter cold snap Tuesday morning.  A strong front passing through the state Monday evening will lead to temperatures only reaching as high as the 30s Tuesday.  

National Weather Service meteorologist Scott Sharp says the chilly weather will stretch into Tuesday night.

Sharp predicts it will be very cold Tuesday night with lows near 20, upper teens in more outlying areas. 

Then on Wednesday we will start what Sharp calls a moderating trend, with temperatures still well below normal for this time of year.

Sixty years ago, Connie Ledgett and her first husband, Jerry Helms, were honeymooning on Oak Island near Wilmington. They had no idea that 140 mile-per-hour winds and an 18-foot storm surge were headed in their direction. That storm was Hurricane Hazel and it would be the strongest category 4 hurricane ever seen in the state. It devastated a 35-mile stretch of the coast.

Forecasters say the worst is over, at least for the Triangle. The cold front, which blew damaging winds and heavy rain is headed toward the ocean.

On Tuesday, a tornado damaged homes and trees near Stedman. Some areas between Fayetteville and Wilson saw more than four inches of rain.

National Weather Service Meteorologist Brandon Dunstan said things will quiet down later today.

Emergency officials were searching Monday for survivors after tornadoes tore through parts of Arkansas and Oklahoma overnight, killing at least 14 people and leveling entire neighborhoods.

"We don't have a count on injuries or missing. We're trying to get a handle on the missing part," Arkansas Gov. Mike Beebe said at a news conference Monday. "Just looking at the damage, this may be one of the strongest we have seen."

A low-pressure system moving up from the south brought rain and sleet to Central North Carolina, and high pressure air from the North is keeping cold air in the area. The result has been freezing temperatures and icy roads.

A winter weather advisory is in effect for most of the state west of the Interstate 95 corridor until noon.

Ryan Ellis is a meteorologist with the National Weather Service in Raleigh. He says ice is especially bad in the Triad.

Updated 10:48 a.m.:

A cold front is moving into the Triangle and creeping eastward toward the coast. Temperatures are expected to drop into the 20s later today.

Scott Sharpe is a senior forecaster at the National Weather Service in Raleigh. He said a wintry mix is expected across the region sometime after lunch.

In light of the winter storm, Governor Pat McCrory says he will work with education leaders to review laws on make up days for public schools.

This week's snow storm led to closings that lasted up to three days for many schools across the state, forcing school officials to make tough decisions on how to make up for the lost time. Many schools still need to make up time from last month's snow.

The two-day snow and ice storm has finally stopped, but hazardous road conditions remain.

Kathleen Carroll is a meteorologist for the National Weather Service in Raleigh. She said temperatures rose into the upper-30s yesterday, causing the snow to start melting.

“The problem is that it didn't really dry out a whole lot before the sun set and temperatures started to fall again,” Carroll said. “So what's we've seen over night is a pretty good development of black ice on area roads.”

The Polar Vortex isn’t loosening its grip on North Carolina. Freezing temperatures hit a record-low seven degrees in Elizabeth City this morning. Chowan County in the eastern part of the state had 9 inches of snow on the ground by yesterday afternoon.

But a series of cold spells and and days of icy roads have led to the cancellation of dozens of blood drives.

Lu Esposito of the Red Cross said the Triangle region is short 1,500 units of blood of all types.
