Honestly, if you're looking at the calendar for Tuesday, January 20, 2026, you’re likely staring down a map of two different Americas. Weather patterns this time of year are usually a mess, but this particular Tuesday is shaping up to be a textbook example of meteorological mood swings.
You’ve got Arctic air dive-bombing the East while the West deals with the aftermath of a "cold atmospheric river."
It’s kinda wild.
Basically, the national forecast is being dictated by a weakening La Niña that just won't quit, mixed with some aggressive "troughing" over the eastern half of North America. If you're in the Northeast or the Great Lakes, you're looking at a day that might actually be the coldest of the winter so far. We’re talking highs struggling to reach the low 10s in spots like the Finger Lakes and Upstate New York.
What is the weather going to be on tuesday across the regions
The big story for Tuesday is the cold.
In the Saint John Valley and upper reaches of Maine, don’t expect much warmth. Highs are pinned around 15°F. It’ll be partly sunny, but that sun is purely decorative—it won't feel warm. By Tuesday night, temperatures are expected to crater to between 0°F and 5°F below zero.

If you're near Syracuse or Lake Ontario, Tuesday's snow is going to be almost entirely lake-effect. West-northwest winds are the culprit here. It’s localized, intense, and frankly, a headache for anyone on the I-90.
The Southern and Western Contrast
Down South, it’s a different world, but not necessarily a better one.
The Southeast is currently gripped by a massive drought—99% of the region is "abnormally dry." While Tuesday won't bring much in the way of relief, there’s a low-pressure system starting to brew near the western Gulf. This might start throwing some heavier rain toward coastal Texas by Tuesday afternoon, though for most of Georgia and Florida, it's just going to be more of the same dry, warm-ish winter air.
Out West? The Pacific Southwest is expected to be in a "cool and rainy" period.
According to the latest trends, the window from January 19-23 is marked for heavy rainy periods. So, while the East freezes, the West is likely just going to be soggy.

Why this Tuesday feels so unpredictable
Most people get winter forecasts wrong because they look at one single number.
But weather in 2026 is being driven by the Madden-Julian Oscillation (MJO). It’s this wave of tropical energy that’s currently crossing the Pacific. When it hits certain phases, it forces the atmosphere into a specific shape. Right now, that shape is a giant ridge in the West and a deep hole (a trough) in the East.
That’s why Tuesday is going to feel like two different seasons depending on which side of the Rockies you call home.
- The Northeast: Highs in the 10s and 20s, lake-effect snow showers.
- The Midwest: Frigid air settling in, though the heaviest "clipper" snow might have passed by Monday night.
- The Southwest: Rainy and cool, a far cry from the usual desert sun.
- The Southeast: Persistent drought conditions with a slight chance of Gulf moisture creeping into Texas.
Managing the Tuesday travel mess
If you're driving Tuesday, watch the wind.
Even where it isn't snowing, those northwest winds are going to be "blustery." In places like Northern Maine or the Great Lakes, gusts could still hit 25 mph. That’s enough to blow whatever dry, powdery snow is left on the ground right across the road, creating whiteout conditions even when the sky is technically clear.

Actionable preparation for Tuesday
If you're in the "Cold Zone" (Midwest to Northeast):
- Check your tire pressure Monday night. Arctic air makes it drop fast.
- Plug in any diesel vehicles if you've got 'em; sub-zero lows are no joke for fuel.
- Clear your vents of any lingering lake-effect snow to prevent carbon monoxide issues.
If you're in the "Rain Zone" (Pacific Southwest to Gulf Coast):
- Clean out your gutters before the Tuesday rain periods start.
- Keep an eye on local flood watches, especially in Northern California where the ground is already saturated from the weekend storm.
Tuesday isn't going to be a "stay inside and hide" day for everyone, but it’s definitely not a day to forget your heavy coat or your umbrella. It’s a messy, divided forecast that really highlights how variable a La Niña winter can be.
