Although Hill communities are enjoying cool temperatures this week, dangerously high temperatures — a heat wave — are expected this weekend and into next week, according to the National Weather Service.

“Very hot, and potentially dangerous, conditions are forecast for Sunday through the early part of next week …,” NWS reported Tuesday morning, June 14.

U.S. Forest Service meteorologist Tom Rolinski, Predictive Services program manager, wrote in his forecast, “The hottest weather so far this season is expected to occur Sunday and Monday with high temperatures in the inland valleys expected to be 102 to 108.”

Monday is expected to be the hottest day. Mountain temperatures may be in the 90s and over 100 in the valleys. The heat wave could extend past Sunday and Monday into the middle of next week, but that is less certain, according to the NWS.

The NWS recommends, “Avoid outdoor activities during the hottest part of the day, drink plenty of water and wear loose, light-colored clothing.
