Midwest Low Pressure Triggers Unseasonable Heat and Storms Across North America and Europe
A low‑pressure system over the U.S. Midwest has pushed unusually warm air from the Gulf of Mexico into eastern North America, causing temperatures to reach about 23 °C (73 °F) in New York and Boston—7 – 10 °C above early November averages. The heat spread into eastern Canada, where temperatures exceeded 20 °C, 10 – 15 °C above normal. The low‑pressure area is moving eastward, and temperatures are expected to return closer to average.
In the southern United States, severe thunderstorms have triggered flood warnings and evacuation orders across multiple states. The storms disrupted polling stations in Florida, Oklahoma, and Colorado. A tornado touched down in Keyes, Oklahoma, damaging a polling station but causing no casualties. State officials have requested federal aid after widespread damage to homes and infrastructure.
Across the Atlantic, authorities in southern France, Corsica, and Sardinia issued severe flood warnings this week. The same low‑pressure system produced thunderstorms and torrential rain, with 50 – 100 mm (2 – 4 in) expected over the next few days. Local totals could exceed 100 mm in Provence‑Alpes‑Côte d’Azur, Occitanie, and Corsica, and up to 70 – 80 mm could fall within a 24‑hour period where rain is most prolonged. Additional rainfall is expected next week as the low pressure remains dominant in the region.
