Little Snow, but Slippery Spots for the Mid-Atlantic
Most roads out of the higher elevations in the Appalachians will be just wet from this event during the day, but slippery and slushy areas could develop toward evening. (Photos.com photo)
A weak system will bring snow, rain and a wintry mix to much of the mid-Atlantic into tonight. As temperatures fall, some roads may get slippery in the I-95 corridor.
The storm has had a history of a coating to an inch of snow over portions of the Plains and the Ohio Valley states since Tuesday.
A bit more snow will be squeezed out over the central Appalachians into this evening with up to a few inches in store over the high ground. The coating to an inch of snow accumulation will then push toward the I-95 zone this evening. A few suburbs west and north of Philadelphia may get a tad more on the grass.
Because of the warm weather much of the winter, above-freezing temperatures today and the some of the sun's energy getting through the clouds during the daylight hours, most of the snow that falls will not accumulate on roads.
A coating of snow can fall just outside of the outer gray area on this map but will tend to be isolated.
However, toward evening, as road surface temperatures cool slightly and we lose the sun's energy, the snow will try to stick to more paved and concrete surfaces. This will begin on elevated surfaces first. In some areas getting rain during the day, a change to a period of snow is possible tonight.
In addition, in all areas where surfaces were made wet by today's snow, rain and wintry mix, falling temperatures tonight can make for areas of black ice.
So a little caution is still advised even after the flakes stop falling or the rain moves away. Property owners may want to treat surfaces late today to avoid overnight icy conditions on sidewalks, driveways and parking lots.
After a little break Thursday and Friday, colder weather is in store this weekend with spotty flurries. However, there is still a chance of a period of steady snow for a few locations, depending on the track of a storm due to form over the ocean.

Hail is much more common during the months of May and June compared to July and August. The main reason is the fact that the freezing level is usually higher during July and August as pockets of cold air in the upper atmosphere are less common as the jet stream weakens and retreats farther north.
