One large system will affect a good chunk of the country the next few days producing scattered showers and storms with some heavy rain possible.
A trough of low pressure will move across the central part of the country through the weekend along with a slow-moving front. This front is forecasted to be located today initially from western Ontario, Canada south-southwest to west TX producing scattered showers and storms from MN to NM. By Saturday morning this front should be located somewhere from Lake Superior to central TX with activity expected from the Upper Midwest east to New England and south to south TX. On Sunday am it will be in the vicinity of Lake Michigan/Lake Huron east to New England and south to central TX with showers and storms possible from the Great Lakes east to New England and south to south TX. Some of the rain associated with these showers and storms could produce heavy rain, therefore widespread accumulations through the weekend could get into the 1 to 2-inch range from south TX north northeast to VT, and then some areas of an inch or more will be possible in MN, and the panhandle of TX.
