Bundle up! Storm Team 4 has declared Tuesday a Weather Alert Days because of frigid temperatures and blustery winds. By the end of the week, we could have our first significant snow this winter.

Wind chills Tuesday were between -5 degrees and 0 degrees Tuesday morinng, and the dangerous wind chills are sticking around. Temperatures aren't expected to rise above freezing all day.

Several school districts announced delayed openings. (Check all school delays here.)

With temps this cold, people are at higher risk for hypothermia, so be sure to layer up and remember your hat, scarf and gloves.

Wednesday will also be chilly, but the winds won't be as brisk, and temps should reach 32 in the early afternoon.

Chances Growing for Snowstorm With Blizzard Potential

Winter won't release its grip on us anytime soon -- in fact, Storm Team4 said there's an increasing chance for significant snowfall at the end of the week.

Heavy wind could come with the storm, which means there's even a potential for a blizzard.

The snow could begin during the day Friday and continue into Saturday.

While it's still too early to predict any specific amounts of snowfall, Storm Team4 says the amount of snow could be significant and could cause travel disruptions by air and ground in the Mid-Atlantic region, as well as power disruptions.

However, if the storm turns farther north or south, that could significantly change the amounts we get.

Stay with Storm Team4 throughout the week as they keep an eye on the approaching storm.
