A dangerous pattern of long-term heat is setting up over Europe this week, and forecast models suggest it could stretch beyond the weekend. Temperatures are running up to 30 degrees above average and long-term heat records are falling in the U.K and France.
The unusual aspect of this heatwave is not only how early it’s coming — heat of this magnitude is more typical later in the summer — but how long it seems likely to last.
England experienced its hottest July day on record Wednesday as the temperature at London Heathrow soared to 98.1 degrees (36.7 Celsius) according to the U.K. Met Office, breaking the previous record set in 2006.
