Troughing over the eastern half of the country will persist through midweek, while ridging in the West degrades beneath the arrival of a transient trough over the Northwest on Monday. A low pressure system will move through the Mid-Atlantic and Northeast over the next couple of days before exiting into southeastern Canada on Tuesday. Today, moderate to heavy lake effect snow is expected downwind of the Lakes; beginning over the Upper Great Lakes today then migrating to the Lower Great Lakes, Ohio Valley and Central Appalachians by this evening. The Chicago metro area could receive between 6-12 inches of snow with isolated higher amounts possible, while Marquette could see over a foot of snow by Tuesday morning. Strong winds will also impact the Great Lakes and Upper Midwest through Monday afternoon, due to a tightening pressure gradient caused by convergence of the digging trough in the East and the approaching ridge from the West. Scattered to isolated rain showers and thunderstorms will spread from the Ohio Valley to Mid-Atlantic/Northeast today. Rainfall will quickly come to an end over New England on Monday. An Arctic airmass will expand from the Great Plains and Mississippi Valley today into the East Coast on Monday. Overnight lows likely in the 20s and 30s through Monday night prompted freeze watches and warnings from parts of the Southern Plains across the Lower Mississippi Valley and into the Southeast/Mid-Atlantic. In the West, an upper ridge will generate above average temperatures this week. A fast moving cold front, beneath a progressive upper trough, will bring rain showers to the Pacific Northwest tonight. Dry and windy weather at the base of the digging upper trough will generate critical fire weather conditions over southern to southeastern Texas today. Red flag warnings are in effect.
