Potent Weekend Cold Front to Break Warm Spell With Rain, Storms and Gusty Winds

Gusty winds with pockets of heavy rain are the main concerns as cooler air follows the boundary.

Overview

  • Forecasters track a strong front sweeping the central and eastern U.S. late Saturday into Sunday, with Kansas City expecting scattered thunderstorms as early as Friday evening.
  • Wind hazards include widespread gusts around 30–40 mph in parts of the Great Lakes and isolated stronger bursts up to 50–60 mph in spots highlighted by local forecasts.
  • Rainfall looks locally significant, with around an inch common in many areas and parts of Wisconsin projected to total 2–3 inches over the next seven days.
  • Temperatures stay unseasonably warm ahead of the front before dropping to highs in the 50s–60s and overnight lows in the 30s–40s, with frost advisories and a freeze watch in parts of Pennsylvania.
  • In the tropics, Tropical Storm Lorenzo is weakening with no land threat, and the Climate Prediction Center notes a low-confidence window for possible Caribbean development Oct. 22–28.
