— STATE COLLEGE — A storm swinging up from the South will spread a period of snow (and rain) from a portion of the Ohio Valley to part of the Northeast, including the Central Susquehanna Valley tonight into Tuesday, forecasters said today.
The premise of a single, moderate storm tracking northeastward entertained last week by AccuWeather.com meteorologists appears to be the most likely scenario.
Enough snow and slush will occur in some locations to slow travel and perhaps foil plans.
“While an exceptionally heavy snowfall is not foreseen, enough snow to sweep, shovel or plow will occur from northeastern Kentucky to northern West Virginia, northwestern Virginia, northern Maryland, southern and eastern Pennsylvania and northern New Jersey,” said Accuweather Meteorologist Steve Travis,
Major highways could have low visibility and road conditions ranging from wet to slushy to snow-covered for a time during several hours.
Temperatures will be marginally cold enough for snow at critical levels in the atmosphere.
Roads are most likely to be snow covered in portions of West Virginia, western Maryland and south-central Pennsylvania late Monday night into Tuesday morning, as the snow will get a jump start in this area, prior to slight daytime warming.
In addition, where snow lingers later in the afternoon and evening in portions of southeastern New England and perhaps Long Island, road surface temperatures may cool enough to allow a small amount of slush and snow on the roads and sidewalks.
Just enough precipitation can reach into part of the Ohio Valley to cause slippery spots Monday night, setting the stage for Tuesday morning’s drive delays.
It is quite possible a person driving from Center City in Philadelphia into interior southeastern Pennsylvania could encounter conditions ranging from wet roads to heavy snow and slushy conditions in as little as 10 miles.
