Meteorologist Max Velocity, speaking on his Max Velocity – Severe Weather Center forecast on December 15, said the United States is on the edge of a “dramatic turn” in the pattern. The big idea from Max Velocity is that the next several days won’t be a steady, normal winter stretch – it’s going to be a chain reaction.
Max Velocity said this shift is setting off “high impact storm systems” with multiple threats happening at once. He listed a major flooding risk, heavy snow, blizzard conditions, a winter warm surge in some areas, and even a possible return of severe weather.
In Max Velocity’s telling, the trigger is the larger-scale pattern – especially the jet stream – lining up in a way that sends storm after storm into the same problem zones. That’s when winter stops feeling like “cold season” and starts feeling like chaos season.
And honestly, that’s the part that hits hardest. It’s not one event. It’s the idea that the atmosphere is about to hit “repeat” several times in a row.
The Jet Stream Setup That’s Driving Everything
Max Velocity said he wanted to start with the jet stream, because that’s what controls the overall weather pattern for the next week. He described a “very rare” setup developing, and he framed it as the steering wheel for what happens next.
According to Max Velocity, the Pacific Northwest is about to deal with a strong atmospheric river event—again. He called it dangerous because it’s pushing “lots of moisture” into the region, which he warned could lead to “catastrophic flooding.”
Max Velocity also said the storms don’t just die out after they slam the Northwest. He explained that energy breaks off those systems and moves east, eventually reaching the Great Plains, the Midwest, and the Ohio Valley.
In his forecast, Max Velocity said the pattern ramps up most around Wednesday and Thursday. That timing matters, because it lines up with the week’s busiest travel window for a lot of people, and it’s exactly when roads can go from “fine” to “closed” in a hurry.
He also noted something that feels almost unfair: while some places keep getting hammered, other parts of the country flip warmer fast because the jet stream lifts north for a time. That’s the setup for the temperature whiplash he kept emphasizing.
Flooding Threat Returns To The Pacific Northwest
Max Velocity didn’t sugarcoat the Pacific Northwest risk. He said the atmosphere is “opening the floodgates” as a “train of storms” impacts the region this week.
He warned that this atmospheric river event is on pace to be one of the more significant ones “in years” across the Pacific Northwest, especially Washington.
Max Velocity also noted that rivers there had already reached some of their highest levels on record recently, which means the ground and waterways may not have much room left to absorb more.
He forecast rounds of rain and mountain snow continuing through the week, with another powerful atmospheric river arriving Tuesday evening. In Max Velocity’s timeline, heavy rain and snow continues into Wednesday, and he mentioned winter storm watches and warnings in places like Montana.
Then he got very specific on rainfall totals. Max Velocity said that between now and Friday, higher elevations could see 5 to 10 inches of rain, and he even mentioned a few select spots that could approach a foot west of Washington.
He said western Oregon, western Washington, and parts of northern California could see 3 to 7 inches at minimum. That’s not “puddles in the driveway” rain. That’s “watch the hillsides and creeks” rain.
Max Velocity also pointed to the human impact with a blunt reminder: he said nearly 100,000 people were evacuated last week in low-lying areas, and he wouldn’t be surprised if something similar happens later this week – especially near rivers.
My own reaction is simple: if you live anywhere flood-prone, the time to “start paying attention” is before the water gets loud. When the pattern turns into repeated storms, the danger isn’t just the peak rainfall hour. It’s the cumulative wear-and-tear on rivers, slopes, and infrastructure.
Snow, Wind, And A Blizzard-Style Setup For The Northern Tier
While the Northwest deals with flooding and mountain snow, Max Velocity said the same storm energy will help generate winter storms farther east. He described a new winter storm forming in the northern Plains late Wednesday night.
Max Velocity highlighted just how intense the low pressure could be. He talked about a 987 millibar system, calling that “very impressive” for the northern tier of the country.
In his breakdown, Max Velocity said late Wednesday into early Thursday could bring light to moderate snow from Montana toward the Upper Peninsula of Michigan, with rain on the southern side in spots like Iowa and near Minneapolis.
Then he got to the part that tends to cause the biggest real-world problems: wind. Max Velocity said the pressure gradient around this system looks tight – meaning the isobars are packed together – and that’s a recipe for very strong gusts.
He said parts of the Midwest could see wind gusts around 50 to 60 mph on Thursday, with even stronger gusts possible farther west. Later in the forecast, Max Velocity said the Dakotas and Nebraska could see gusts roughly 50 to 70 mph early Thursday.
He also warned that blizzard conditions are possible in parts of Minnesota, Wisconsin, and the Upper Peninsula of Michigan. He made the point that it doesn’t take a record snowstorm to create blizzard-like travel – if you already have snow on the ground, strong winds can turn it into whiteout conditions fast.
This is where winter gets dangerous for regular people doing regular things. Strong wind plus existing snow turns highways into traps. You don’t need to be reckless to get stuck—you just need to be early, unlucky, or on the wrong road when the visibility collapses.
A Temperature Whiplash That Could Melt Snow Fast
Max Velocity said one of the biggest changes over the next 7 to 10 days will be temperatures. He described a sharp “temperature flip” that sends parts of the country from well below average to well above average in a matter of days.
He said the southern Plains and the Southeast could run 10 to 25 degrees above normal, after a major arctic blast hit millions in the Midwest and Ohio Valley.
He also pointed out the contrast: the East Coast remained much colder than average in the near term, while the West Coast was already very warm with “dozens of record highs” recently.
Max Velocity said that by Wednesday and Thursday, heat builds further into the Pacific Northwest—at the same time rain and snow are falling – adding to the flood concerns because warmer air can boost snowmelt and increase runoff.
He also said a warm pocket of air pushes into the Midwest and Ohio Valley, with some areas as much as 25 degrees above average, including Missouri. Max Velocity specifically warned that snow that fell in Illinois and Indiana would likely melt on Thursday.
He noted the warm-up may only last about 36 hours, but even a short-lived thaw can be enough to create new problems – slushy roads, refreezing later, and added water feeding already swollen creeks.
Then, Max Velocity said another shot of arctic air arrives Friday and Saturday, though he described it as not as intense as the recent blast. Still, he said it brings colder air back into the upper Midwest and Great Lakes.
That’s classic winter whiplash: melt, then refreeze, then blow snow around again. It’s not just annoying. It’s when people get caught off guard because yesterday’s problem was ice and tomorrow’s problem is wind.
Severe Weather Mentioned, But Not The Main Story
Max Velocity also warned that as warm air surges north, severe storms may return in parts of the Ohio Valley. He mentioned the possibility of damaging winds and said an isolated tornado threat could be possible.
But Max Velocity also sounded cautious. He said he didn’t think temperatures and dew points would be high enough for a big tornado risk, and if one happened, it would more likely be in far southern Kentucky or Tennessee. Even there, he said the odds looked low for Thursday.
Still, Max Velocity said isolated damaging winds and thunder “are going to be on the table” during the day Thursday. And that’s worth respecting, because wintertime severe weather tends to catch people mentally unprepared.
A thunderstorm in December doesn’t feel real until it’s rattling your windows.
What Max Velocity Said About Christmas
Looking ahead, Max Velocity said things get more uncertain closer to Christmas. He said the GFS model hints at an active pattern along the West Coast around that time, which could translate east if a storm ejects over the Rockies.
For temperatures, Max Velocity said Christmas currently looks above average for most of the country, which would make a white Christmas less likely in many places.
He also mentioned the GFS showing an extreme “absurd scenario” with 70s near Chicago and 40 degrees above average, but he flat-out said he didn’t think that would happen.
That honesty matters. Forecasting is about probabilities, not drama. Max Velocity’s tone here was basically: watch it, but don’t marry the wild model run.
In the meantime, his larger message stayed steady: the pattern is shifting hard, and winter is about to behave differently – flooding risk in the Northwest, snow and wind for the northern tier, and a temperature rollercoaster that can change conditions fast.
And if there’s one practical takeaway from Max Velocity’s forecast, it’s this: don’t treat the next week like a normal winter week. Plan like conditions can flip overnight – because, in this setup, they really can.
