Midwest weather system sends late summer warmth to New York and Boston

A low pressure system over the US Midwest has drawn warm air from the Gulf of Mexico into the north-east, bringing New York and Boston an unusually late spell of summer-like weather. Temperatures near 23C were around 7-10C above early November averages, while parts of eastern Canada also saw temperatures above 20C. The system is expected to move east, allowing temperatures to return closer to average.

Elsewhere, severe thunderstorms brought flood and evacuation warnings across several US states, disrupting midterm voting in Florida, Oklahoma and Colorado. A tornado damaged buildings in Keyes, Oklahoma, and forced a polling station to relocate; no deaths were reported. Officials have sought federal aid for damage to homes and infrastructure, while parts of southern France, Corsica and Sardinia face heavy rain, with 50-100mm forecast and local totals potentially higher.
