The eastern half of the United States faces an intense heat wave starting late this week and peaking next week that could produce dangerously high temperatures over a large area for an extended period. It could threaten records and place vulnerable groups of people at risk from heat-related illnesses.
Over the weekend, widespread highs in the mid-90s to around 100 — some 10 to 20 degrees above normal — will spread across the southern Plains, South and Midwest. By Monday, the heat will swell into the Ohio Valley before reaching the Mid-Atlantic and Northeast shortly thereafter.
For much of next week, a punishing combination of heat and humidity will remain lodged over the East — although some relief may arrive in the Upper Midwest during its second half.
