Warm, Sunny ‘False Fall’ Grips Much of U.S., Cooler Change Due Midweek

Southerly flow beneath a high-pressure ridge is sending late-summer warmth north before a midweek front brings rain then a cooldown.

Overview

  • High pressure is delivering widespread 70s to 80s with dry skies through the weekend, creating ideal conditions for outdoor events from the Northeast to the Plains.
  • The National Weather Service posted winter weather advisories in central Alaska with 3–6 inches of snow possible and warned of earlier freeze and frost in parts of the Northeast.
  • Persistent dryness is worsening drought in the Northeast, prompting New York’s temporary burn ban and conservation appeals from New York and New Jersey officials, with fall foliage duller and shorter-lived in some areas.
  • Rain chances increase unevenly from late weekend into next week, including the potential for heavy downpours and localized coastal or street flooding in the Southeast.
  • A cold front expected Tuesday into Wednesday will bring more widespread showers and a noticeable cooldown, with some high elevations in the Intermountain West seeing minor snow as temperatures trend back toward fall norms.
