Often times with a cold front, precipitation falls ahead of it. We are tracking a front that is part of the Colorado low, and behind that front will be significantly colder air. This front will be strong with warmer temperatures ahead of it, then Arctic air behind it.
On Tuesday, we’ll be looking at a sharp line of rain stretching from western New York southwestward down to eastern Texas. As the day progresses, the line will track eastward, getting into New England by the afternoon. The Southeast, except for Florida, will also get in on the rain by the evening.
By Wednesday, the front will begin to stall, so it’s looking to be an ugly, wet, and rainy day for the Gulf Coast, Georgia, Carolinas, and the Mid-Atlantic coast, and southeastern New England.
It’s this front that may instigate the development of a late-week nor’easter.
Rainfall associated with this front will be light overall, adding up to an inch in most locations. It will be a bit heavier in the lower Mississippi Valley, Carolina coasts, and New England.
