Weekend Warmth Builds in Northeast Before Early-Week Heat Wave Risk

A strengthening high-pressure ridge will drive the season’s first burst of near-90-degree heat early next week.

Overview

  • Following Friday’s cool showers, forecasters expect a sunnier, warmer weekend in the Northeast and Ohio Valley with highs in the 70s to low 80s.
  • Inland temperatures are projected to reach around or above 90 degrees Monday and Tuesday in parts of Pennsylvania and New England, with some forecasts reaching the mid-90s and flagging the first 90s of 2026.
  • Coastal spots stay milder, with sea breezes keeping places like Cape Cod in the 60s to low 70s while inland areas surge much higher.
  • A stronger round of showers and thunderstorms is favored on Wednesday as a cold front moves through, and some local teams have labeled it an “impact day.”
  • In the UK, the Met Office expects a chilly, showery weekend with heavy Sunday downpours, followed by a possible bank holiday warm-up into the low 20s Celsius in southern England.
