DC Hits 102F Monday 7/15; Heat Index 7/16 Pegged At 105F - Hottest Summer On Record So Far

For a second straight day, Washington soared into the triple digits, setting a record high. Its high of 102 Monday followed Sunday’s 101, at the midpoint of a summer that has been the hottest on record to date. The ongoing heat wave — the third of the summer — is perhaps the most intense and dangerous.

After reaching 96 on Saturday, 101 on Sunday and 102 on Monday, Washington is forecast to reach the upper 90s to 100s on Tuesday and Wednesday as well. With high humidity, the heat index is expected to reach 105 to 110 degrees, prompting the National Weather Service to put most of the region under excessive-heat warnings through Tuesday.

The heat and humidity “will significantly increase the potential for heat-related illnesses, particularly for those working or participating in outdoor activities,” the Weather Service said. “Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances.”

EDIT

While this heat wave looks to be shorter than previous ones this summer, it could very well end up as the hottest and most dangerous. Much of the region is forecast to reach a Level 4 on the Weather Service’s HeatRisk scale — which rates the danger of the heat to human health — through Tuesday. That is the highest level, described as “rare and/or long-duration extreme heat with little to no overnight relief.”
