Rain will continue for portions of the northeastern U.S. today as a low pressure system moves northward across the region. The most widespread rain will be across central and northern Maine, where rain could persist into late afternoon or early evening. Drier conditions will prevail across New England tonight into Thursday morning as the low pressure system moves away from the region. A low pressure system will move from the Great Basin into the Rockies today ahead of a deepening upper-level trough. Snow levels will lower as the trough moves overhead, and snow is expected to become widespread across the central Rockies by this evening, with heavy snow possible. Gusty winds will also be possible. On Thursday, the system will begin to move from the central Rockies into the plains resulting in widespread rain and snow across the northern and portions of the central plains as well as portions of the Upper Midwest by afternoon and evening. The low pressure system will continue to deepen into Friday as it moves into the Midwest. Heavy snow as well as gusty winds will be possible during this time across portions of the northern plains and Upper Midwest. Farther south, in the warm sector of the system scattered showers and thunderstorms are expected to develop by Thursday night and Friday from the southern plains to the mid-Mississippi valley. Warm temperatures will persist ahead of the western/central U.S. low pressure system as high pressure at the mid and upper-levels remains overhead. Afternoon high temperatures today are forecast to be 15 to 30 degrees above average across much of the central U.S. The warm temperatures will migrate eastward into the Great Lakes and Ohio valley on Thursday as colder air begins to move into the central and northern plains behind the incoming cold front.
