Black Ice AroundJanuary 23rd, 2014 at 8:01 am by Jeremy Wheeler under Weather
Black Ice was a problem for some folks this morning. Yesterday we had a lot of sunshine. Plus, the ground temperatures probably were still a little above freezing in places. So there was melting on many roads Wednesday. Then last night the temperatures dropped as expected, and many spots froze over again. So what we had this morning was a mix of lights and darks on the roads. It was very difficult to determine what was black ice and what were simply dry patches.
The problem is that the salt on the roads lightens up the color of the asphalt. That helps some of the dry spots blend in with the regular snow and ice. Then there are also a few melted spots (due to the salt and vehicles). Those show up as dark as well. Finally, there are plain dry spots on the asphalt which let the black ice blend in. So be careful on the roads this morning.
High pressure is in the region. So we’ll see plenty of sunshine today. The winds will be much less than yesterday, but they will still run out of the southwest at 5-15mph.
We’ll get into the low/mid 30s with mostly sunny skies this afternoon. It won’t be warm, but it will be better. Roads should melt again, and hopefully the water evaporates before this evening. Tonight a cold front will move through the region. It is expected to move through as a dry front. It’s possible that we could see a flurry or two, but that’s about all we would see. Winds will pick up tonight out of the northwest. They’ll pick up to 10-20mph with gusts up to 30mph.
Tomorrow we’ll see more sunshine, but it will be windy and cold again. Highs will be in the mid 20s with winds gusting out of the northwest at 25mph.
We’ll finally warm up on Saturday with highs in the 40s, but it will be very windy. Basically, a strong area of low pressure over the northeast states will create a strong pressure gradient between a high to our south. Winds will be out of the west and some of the gusts could be over 30mph. We’ll be dry over the weekend, but I can’t rule out a couple of flurries here and there. Our next best chance for precipitation will come around next Wednesday. An area of low pressure offshore will form and move away from us at that time. On the western edge of it some of the models put snow showers over the Outer Banks and parts of northeast North Carolina. So far I only have flurries for Hampton Roads, but I may have to upgrade if the moisture gets closer. Stay tuned!
There has been a lot of cold and precipitation in the east lately. However, there has been a huge drought ongoing in the western states with warm temperatures.
