As winter 2025-26 approaches, “The Internet’s Weatherman” meteorologist Ryan Hall forecasts a season of intense cold across North America, driven by potential polar vortex disruptions. A weak La Niña and specific atmospheric conditions signal a 60-75% chance of sudden stratospheric warming events, which could unleash Arctic air into the mid-latitudes, causing significant temperature drops from January through early March.
“In this forecast, I break down why this winter will create two completely different Americas: a frozen north vs a warm south, with an explosive battleground in between where severe weather and massive snowstorms will collide.”
Key Points:
-Why a weak La Niña means MORE extreme weather swings
-The Polar Vortex wildcard that could unleash historic Arctic blasts
-Exact regions facing 140% normal snowfall vs severe drought
-Why the Midwest becomes ground zero for ice storms AND winter tornadoes
-6-9 major Nor’easters targeting the Northeast (normal is 4-6)
-The specific dates when Arctic invasions are most likely
Polar Vortex Disruptions Bring the Chill
Sudden stratospheric warming events may destabilize the polar vortex, allowing frigid Arctic air to spill south. When this happens, temperatures could plummet 15-25°F below normal, with wind chills reaching -30 to -50°F in some regions. These cold snaps could persist for 4-8 weeks, transforming winter weather patterns. Two to three major disruptions, with the most intense impacts expected between January and March, potentially creating memorable Arctic outbreaks.
Regional Impacts: Where the Cold Hits Hardest
- Pacific Northwest: Seattle and Portland face a 33-40% chance of below-average temperatures, with consistent cold not reliant on polar vortex disruptions. The Cascades could see 20-40% above-normal snowpack, a boon for skiers and water supplies.
- Northern Cascades could see 20-40% above-normal snowpack, a boon for skiers and water supplies.
- Northern Plains and Great Lakes: Minneapolis, Chicago, Detroit, and Buffalo are primed for Arctic invasions. Lake-effect snow could dump up to 3 feet in short bursts, with 20-40% above-normal snowfall. Frequent Alberta Clippers may bring 3-6 inches of snow per event.
- Midwest and Ohio Valley: St. Louis, Indianapolis, and Cincinnati will experience temperature swings and a 35-40% higher chance of ice storms, particularly in northern Texas, Oklahoma, and Missouri. Enhanced severe weather risks, including winter tornadoes, are also possible.
- Northeast: Philadelphia, Boston, and Maine could see 6-9 significant Nor’easters, especially in February and March, driven by a negative North Atlantic Oscillation phase, leading to intense coastal storms.
- Southwest and Southeast: Phoenix, Las Vegas, and Los Angeles face warmer-than-normal conditions with a 33-50% chance of above-average temperatures and 40% below-normal precipitation, worsening drought conditions. The Southeast, including Atlanta and Charlotte, may see milder weather but remains at risk for occasional cold snaps and severe storms.
A Winter to Remember
Drawing from historical patterns, particularly the chaotic 2010-11 winter, Ryan Hall suggests this season could bring record-breaking cold and snow, especially in the Northeast, where snowfall could reach 140% of normal. With potential for prolonged cold and extreme weather, staying prepared with reliable weather tools is crucial for navigating this dynamic winter season.
