A deep low pressure system over the upper Midwest on Friday evening will continue to move northeastward across southeastern Ontario and western Quebec on Saturday...with snowfall tapering off across the Upper Midwest overnight. A secondary but not particularly intense low pressure center will develop over the Middle Atlantic states this evening and move rapidly northeastward and reach eastern New England by Saturday morning before passing east of Maine by Saturday evening. Rain will fall along coastal sections of the Northeast with freezing rain across the interior of northern New England with several inches of snow expected across central and northern Maine. On Saturday...high pressure will build eastward from the Midwest across much of the east bringing cool to seasonable temperatures across much of the East. A developing trough over the western United States will continue to bring scattered showers and mountain snow to portions of the western United States into Saturday. As the trough continues moving east...it will interact with the frontal system over the Gulf Coast left from the previous storm system to generate a increasing area of rain/showers and thunderstorms on Saturday. Showers will develop along the frontal boundary along the Gulf Coast...while moisture will be drawn northward ahead of a developing low pressure area over the Southwest...with rain and thunderstorms developing over Texas late on Saturday and then spreading northward from the Gulf Coast across the lower Mississippi Valley into the Southeast on Sunday. A new area of low pressure is expected to develop near western Louisiana late on Sunday and this next storm system is expected to become a widespread rainmaker and possible severe storm producer late in the weekend into early next week for much of the eastern half of the country.
