A lot of weather will be going on to end of 2022 and the start of 2023 with 3 separate systems affecting a good chunk of the country.
First, a trough and cold front will continue to move through the eastern third of the country the next couple of days producing rain for the most part, though a few wrap-around isolated snow showers are possible in northern New England on Sunday. Activity will be focused from the central Gulf coast to the eastern Great Lakes today with an isolated severe storm possible for areas closer to the Gulf, and then on Saturday activity will be focused from northern Florida to New England with a few severe storms possible again for areas closer to the Gulf coast.
Further west into the Upper Midwest a disturbance will track through this region producing light precipitation. Mainly snow is expected with a mix possible at times in southern MN and southern WI, and any precipitation into northern IA and northern IL should mainly be rain. Up to an inch or a little more of snow accumulation is possible in parts of northeast MN, northern WI, UP of MI, and northern lower MI.
Finally, another trough works its way through the western third of the country and will produce widespread rain and snow. Widespread rain amounts in the 1-3 inch range are likely up and down the CA coast and could extend into southern OR. Local amounts of 3 or more inches are possible around and south of the Bay Area, and north of the Bay Area some areas could get 5 or more inches by the end of the weekend. A half inch or more could fall in Phoenix and Las Vegas. and 2 inches possible in Salt Lake City. Widespread snow amounts in the q-2 feet range are likely in the mountains with 3 feet or more possible in spots in northern UT, western WY, northern NV, and the Sierra Nevada in CA. A sneak peek into Monday, a severe weather event is possible in the Mid and Lower MS River Valley as this system heads into the Plains.
