Low pressure in US midwest brings unseasonable heat to New York and Boston

By · Via The Guardian · Published by Everything Blog

In short

The unseasonable warmth stretching from major northeastern hubs into eastern Canada is anticipated to ease as the Midwestern low-pressure zone tracks toward the Atlantic. However, the system's trailing storms have already forced emergency evacuations and interrupted civic operations across Florida, Oklahoma, and Colorado. In Keyes, Oklahoma, a tornado destroyed homes and mandated the relocation of a local polling location. Similar extreme weather also developed overseas, where an unrelated Mediterranean system threatens southern Europe with torrential, flood-inducing rainfall.

The unseasonable warmth also spilled into parts of eastern Canada, with temperatures exceeding 20C, about 10-15C above normal for the time of year. The balmy conditions were the result on an area of low pressure in the US midwest, dragging up exceptionally warm air from the Gulf of Mexico along its eastern flank. This area of low pressure will gradually drift eastwards, allowing temperatures to fall closer to the average.

Further south in the US, severe thunderstorms have resulted in numerous flood warnings and evacuation warnings being issued this week across many states, with disruptive weather impacting polling stations in states such Florida, Oklahoma and Colorado. The powerful thunderstorms this week even resulted in a tornado touching down in Keyes, Oklahoma, forcing a relocation of the polling station. The tornado left extensive damage across the town,…
