Cold weather across large parts of the U.S. and Europe is likely to hang on through at least mid‑February 2026, with a slow and choppy warm‑up rather than a clean, sudden end.

Big picture: why it’s still so cold

  • A disrupted or collapsing polar vortex is dumping repeated waves of Arctic air into North America and parts of Europe, which keeps resetting any brief warm‑ups.
  • Long‑range forecasters say these cold outbreaks are expected to continue into the first half of February, and possibly linger beyond that in the eastern U.S. especially.

When does it start to ease?

  • Forecasts point to slightly less extreme cold after about February 8–11, with a few days here and there that feel more “normal” for February instead of brutally cold.
  • Experts caution that the overall pattern stays tilted cold through at least mid‑February, so any warm spell may be quickly followed by another cold shot.

Region‑by‑region trend (high level)

  • Eastern and central U.S.:
    • Repeated Arctic blasts likely through mid‑month, with some of the coldest air of the winter early in February.
* After that, cold risk remains, but individual outbreaks may be a bit less intense and shorter.
  • Western U.S.:
    • Much milder overall, with temperatures frequently above average and fewer true cold snaps.
  • North America + Europe (general):
    • The polar vortex disruption supports a prolonged window for below‑normal temperatures, especially in February, though exact timing and severity vary by country and even by week.

Simple rule of thumb

  • Expect “real winter” (frequent below‑normal days, risk of snow/ice) to persist into at least the second half of February.
  • The feeling that the cold is finally “ending” will likely come not from one specific date, but from fewer intense outbreaks and slightly longer mild spells as late February approaches.
