A Messy Tuesday Evening CommuteJanuary 20th, 2014 at 6:03 pm by Tiffany Savona WAVY under Weather
Well…the afternoon computer models are in and not much has changed in the overall thinking with this storm system. The highest totals will likely still remain north of the metro, across the Middle Peninsula, Northern Neck and Eastern Shore. These northern areas will see the colder air move in sooner than others. The National Weather Service has issued Winter Storm Warnings (pink) and Winter Storm Watches (blue) for some parts of the region. The watch area has now been expanded to include all of Southside Virginia.
One change in the computer models is the timing of the cold air. It looks like the cold air will arrive a few hours later than what was expected earlier. This means that we will see a wide range in high temperatures. It also means that some of the precipitation may start out as rain before changing over to snow. This area of low pressure is going to have a lot of energy to work with, so the changover from rain to snow will be very quick. Our latest computer model has this solution at 3 PM. If we do see rain first, it will only be for a short amount of time.
Notice that the snow becomes more widespread by 7 PM. If possible, you may want to leave work a few hours early to avoid problems on the roads.
Highs temperatures across the Northern Neck, Middle Peninsula and Eastern Shore will only be in the mid to upper 30s. The Peninsula should see highs in the upper 30s and lower 40s. Southside will see highs in the mid to upper 40s with lower 50s possible across North Carolina. Yes the ground will still be warm especially after highs in the 60s today. But I think the snow will overcome this and accumulate once it starts falling. Keep in mind that temperatures will be dropping throughout the day and should dip below freezing after dark for most areas.
Here is the latest thinking in regards to potential snowfall totals tomorrow.
Here are some times on when you can expect the snow to move into your area.
Northern Neck, Middle Peninsula, Eastern Shore: Between 1-3 PM
Peninsula: 3-5 PM
Southside: 5-7PM (*Notice that Virginia Beach could see slightly higher totals with bay effect show showers late Tuesday night/Wednesday morning)
North Carolina: After 7 PM
The snow is going to create lots of problems on the roads, especially since it will be hitting the metro areas around drive time. We are also concerned about travel early Wednesday morning because any snow that accumulates will freeze overnight and create slippery roads. Temperatures are going to be in the teens with wind chill values at or below 0 degrees Wednesday morning. We are not expecting the snow to melt since temperatures are going to stay well below freezing all day on Wednesday.
