Recent moisture lingering from a nor’easter and advancing cold fronts are the main drivers shaping precipitation patterns across parts of the Northeast and Midwest on September 28, 2026. Official forecasts from NOAA and local meteorological services indicate areas of drizzle, scattered showers, and possible thunderstorms in locations such as the Finger Lakes region and Green Bay, while many other U.S. and international sites remain partly sunny or dry under high-pressure influence. Model consensus shows limited disagreement on timing, with steering winds favoring north-to-northeast flow that keeps moisture localized. Resolution depends on verified daily precipitation totals at designated weather stations, with final data typically available shortly after midnight local time. Traders monitoring real-time observations and updated model runs from NOAA can anticipate any late-day shifts in coverage.
