A low pressure system along the Southeast U.S. coastline early morning will move northeastward along the coast through the next few days. This system will bring rain to portions of the Carolinas and the Mid-Atlantic region today, and into the Northeast Tuesday into Wednesday, according to the National Weather Service.
Farther west, a frontal system will move inland in the Pacific Northwest today, bringing rain and high elevation snow. Another low pressure system will move onshore in the Northwest on Tuesday, bringing another round of rain and high elevation snows. This second system will be associated with a deepening upper-evel trough, which will gradually lower snow levels across the West as it moves inland.
