Coldest Air of the Season Moving in This Week!January 20th, 2013 at 9:28 pm by Tiffany Savona WAVY under Weather
It was a beautiful weekend across Hampton Roads as high temperatures were well above normal for this time of year. However, many folks may be wondering when it will start to feel like winter again. The answer to that question is….very soon!
We are expecting big changes as we head into the work week. The first cold front will move in tonight ushering in some cooler air for M.L. King Day. It will be cooler on Monday, but still pretty nice with highs near 50°. The second cold front, or arctic front, arrives Monday night. A deep trough or large dip in the jet stream will allow this cold, dry air from Canada to move into the Northern Plains and Great Lakes region first. Then this airmass will continue to modify as it slides southeast from there, moving into Hampton Roads by Tuesday.
Many areas in North Dakota and Minnesota are seeing temperatures below zero tonight. Highs will not even get above zero degrees on Monday for these same areas. This means that temperatures will be about 20-25 degrees below normal for this time of year across the Northern Tier of the U.S. The air will modify a little bit before moving into Virginia and North Carolina. We will not see temperatures below zero degrees, but we will see the coldest air in nearly 2 years. Check out the temperature trend over the next few days.
Hampton Roads will see high temperatures about 15 degrees colder than normal for part of the upcoming week. So far this season, we have only seen 1 day where highs were in the 30s. That was back on January 3, when the Norfolk Airport recorded a high temperature of 38 degrees. The last time we saw highs at or below 32° was in January of 2011, almost 2 years to the date. Keep in mind that wind chill values will be in the 20s all day long on Tuesday. Make sure you are prepared for the cold this week. Be sure the kids are bundled up completely before heading out to the bus stop each morning. Great weather to build a fire in the fireplace if you have one. Stay warm!
