Overview

• High pressure keeps much of the Midwest, Great Lakes and interior Northeast warm and dry, with highs largely in the upper 70s to low 80s.
• The D.C.–Baltimore corridor expects Saturday showers and thunderstorms with pockets of heavy rain, generally totaling one-half to about one inch, before a sunnier Sunday.
• The National Hurricane Center is monitoring Hurricane Humberto well offshore and Potential Tropical Cyclone Nine near the Bahamas, which is likely to be named Imelda.
• Guidance suggests Humberto could influence the Bahamas system’s motion, potentially stalling it near the Southeast coast and increasing the risk of heavy rain, strong surf and coastal flooding early next week; confidence in exact impacts remains low.
• Model consensus points to a cooler, drier Canadian high settling in by mid to late next week, bringing more seasonable fall conditions after the warm spell.
