Two systems producing widespread rain and snow will affect parts of the country over the next few days.
First, a low-pressure system will begin today somewhere in the TX panhandle or southwest OK and will move northeast through the weekend making it into northern IA by Saturday and, and to James Bay in Ontario Canadanby Sunday am. A cold front will also accompany this system and be located today from the Rio Grand Valley to the western Great Lakes today, and on Saturday will be located from the western Gulf to the eastern Great Lakes. Widespread precipitation is expected in the vicinity of the cold front and within the circulation of the low. Widespread rain accumulations are expected from east TX to northern lower MI, and a band of 2-5 inches is possible from northwest MO to eastern UP of MI. A few severe storms will be possible today in east TX and could get into OK, AR, and LA as well.
The other system will affect the Northwest as waves of energy move through this region producing widespread rain and snow, and heavy at times. Widespread rain amounts of 5-10 inches are possible through the weekend in western WA and western OR. Heavy snows are likely as well in parts of the mountainous regions of WA, OR, ID, western MT, northern UT, and northwest WY where a lot of areas could get around a foot with a few possibly getting close to 2 feet.
