Overview

• Overnight showers and isolated thunderstorms have largely moved on, with the heaviest rain ending by midmorning and wind gusts commonly in the 25–35 mph range in several regions.
• Temperatures trend cooler through midweek under a classic autumn pattern, as reinforcing fronts bring occasional light showers and periods of blustery conditions.
• Rainfall has been modest at roughly 0.1 to 0.5 inches in most spots, which provides only limited relief for areas still flagged as abnormally dry or in drought.
• Early-season cold hazards are emerging, including a Frost Advisory this morning in parts of northeast Wisconsin and the potential for late-week frost or even a few high-elevation flakes in the Northeast.
• A tropical wave labeled Invest 98-L in the Caribbean shows increased odds of development this week, though forecasts indicate no immediate threat to the United States.
