As Sunday night turns into Monday here in the United States, the system that’s kept the Southern Plains cool, cloudy, and rainy will fire up the afterburners and roar out of the Southern Plains with widespread rain and thunderstorms in Texas, Oklahoma, and vicinity and hecka widespread snow from Central Illinois west to the Central Rockies and all throughout the Southwest and mountainous interior of the West Coast. Throughout Monday and into Tuesday, expect showers and thunderstorms across the South, the Ohio River Valley, and the Mid-Atlantic, with snow and ice still being the rule in the Intermountain West and Central Plains, while also spreading into the Midwest (mainly Lower), Great Lakes, and the vicinity of Pennsylvania.

Tuesday into Wednesday will see New York and New England get into the winter weather action, as well, and – ding-dong, West Coast! – a powerful low rolls in from the Pacific bringing y’all lowland rain, highland snow, and the possibility in Central and Southern California for flooding and mudslides due to expected very torrential rains. By Wednesday night, the Mid-Atlantic and Appalacians get in on some winter weather action in the mountains and highlands, with rain in the lowlands.

Thursday afternoon, the Mid-Atlantic storm moves out and the activity in the Eastern half of the country becomes limited to isolated snow showers in the Great Lakes region, while the storm in the West keeps on truckin’ over California, the Sierra Nevadas, and the Northwestern Rockies.

Friday, the Great Lakes lake-effect snow expands to snow for most of the Northeastern U.S. The California/West Coast storm moves inland, bringing rain and storms to the Southwestern deserts and yet more snow for the highlands and mountains.

Finally, Saturday, gentler rains, with highland snow, slide onto the West Coast for a soft encore, as the other system exits the Rockies after dumping some snow in the morning to then bring widespread showers and thunderstorms to the Central and Southern Plains and snow to the Northern Plains & upper Midwest. Expect this storm to, by Saturday night, spread wintry weather to the Great Lakes, Lower Midwest, and even down into the Mid-Atlantic states, with rain for the South.

Keep in mind that on the northern half of the West Coast, light snow accumulations will be a thing even in lower elevations. Portland could see a cumulative 1-2 inches, and Seattle a dusting.

In Alaska, now through Wednesday will mainly see the snow, ice, and very cold rain over the far southwest – the Aleutians and the tip of the mainland – and on the Southern Coast… this will, by Thursday, be spreading further into the interior of the state, where it’ll kinda chill out by Saturday.

Hawai’i will see isolated to scattered tropical showers and thunderstorms throughout the week, mainly during the day (daytime heating).

Temperatures will be seasonably cool to mild across the Lower 48 through mid-week, with a southerly and easterly push by arctic air masses as we go into Thursday and Friday, then getting a bit more towards the seasonal side by the week’s end Saturday night. It will be seasonably frigid across Alaska, and mild to warm for the Hawai’ian Islands.
