The second winter storm watch of the season has been issued by the National Weather Service, which is predicting about 5 inches of snow in the region by tomorrow.
The storm watch begins this afternoon, but most of the snow is expected to fall after midnight and through tomorrow morning, said weather service meteorologist Howard Silverman. The storm was forming yesterday in the central Plains.
“We’ve got a fairly interesting weather system [tonight] into Friday,” said Andy Woodcock, another weather service meteorologist. “It’s going to start off with snow [tonight], with some sleet before 6 a.m. D.C. could be a transition point. But what weather happens will depend where you are.”
Most of the traffic problems are expected to occur during tomorrow morning’s rush hour.
Road crews had little trouble with the area’s first significant snow, which started Monday at about 2 p.m. and continued into early Tuesday.
About 4 inches of snow caused some schools to close early on Monday and open two hours late on Tuesday. The southeastern part of the region had larger accumulations. Most roads remained clear, though icing overnight in the past few days has caused numerous accidents.
Meteorologists said yesterday that there was an 80 percent probability that the snow will arrive between tonight and noon tomorrow. The temperature tomorrow night will be about 27 degrees. The high for tomorrow will be about 37 degrees.
The forecast for Saturday is mostly sunny skies, with the temperature increasing to 41 degrees. Some clouds will cover the region Sunday, but the temperature is expected to reach 43 degrees.
