Cool Air Follows Debby in Northeast
- Cool, dry air is moving into the Northeast following the effects of Hurricane Debby.
- Despite the arrival of this cooler air, many rivers are still experiencing rising water levels.
- This weather change is expected to impact regions from the Midwest through to New England.
As rivers continue to rise following the impact of Tropical Storm Debby, AccuWeather meteorologists report a significant shift in weather patterns. A surge of cool, dry air from Canada is expected to move across the Midwest, central Appalachians, mid-Atlantic, and New England, providing much-needed relief to millions grappling with tropical humidity and flooding. Daytime temperatures in the upper Great Lakes region are forecasted to remain in the 60s Fahrenheit through the weekend, with cooler air extending into the Ohio Valley and Northeast. The arrival of this cool air is particularly notable for August, as temperatures in the central and northern Appalachians are predicted to drop into the 50s by Saturday night. This change may prompt some residents to close windows to keep the chill at bay. Additionally, humidity levels are set to decrease east of the Appalachians, leading to cooler nights and mornings, with lows primarily in the 60s. However, the western regions may still experience showers and thunderstorms as warm air persists. In the aftermath of Debby, significant rainfall has resulted in moderate to major flooding across several states, including Georgia, the Carolinas, Pennsylvania, New York, and New England. While rivers are expected to crest in the coming days, areas in lowland Georgia and the Carolinas may take longer to recover. Meteorologists warn that slow-moving storms could exacerbate existing flooding issues, urging swimmers to heed local beach closures.
