Warm Start to Week Across U.S. as Coastal Showers Return and West Coast Storm Triggers Flood Watches

A midweek front will deliver a noticeable cool-down, bringing drier air with a risk of inland frost.

Overview

  • Many regions begin the week mild to warm and mostly sunny, with highs near 70°F around the Great Lakes and upper 80s to near 90°F in parts of the central and southern Plains.
  • Scattered light rain expands late Sunday into Monday in the Mid-Atlantic and Northeast as a coastal and upper-level low lingers, with most spots forecast around 0.30–0.75 inches.
  • Breezy conditions accompany the pattern, including gusts of 25–35 mph in places like Minnesota, with showers tapering there by Monday morning.
  • A separate Pacific storm prompts National Weather Service Flood Watches along parts of the West Coast, with burn-area flash flood concern and widespread rain Monday into Tuesday.
  • A cold front midweek is expected to drop highs into the 50s and 60s in several areas and may allow frost in sheltered inland locations as drier air settles in.
