“The duration of this heat wave is notable and potentially the longest experienced in decades for some locations,” the NWS continued.
“We have already seen some pretty significantly high temperatures in our area,” said Ted Whittock, a meteorologist with the National Weather Service in Phoenix. “We are recommending that everyone reduce their time outdoors between 10 a.m. and 6 p.m., stay hydrated, and wear light, looser fitting clothing.”
Through June 22, the high heat will move east from the Ohio River Valley area to the Northeast United States, the agency said. Some places will see 105 degree F temperatures in the day, and they will only drop to the mid-70s at night.
Heat Stroke Symptoms
Health officials say that it’s important to know the symptoms of heat stroke or heat exhaustion, which includes dry reddish skin, headaches, chills, delirium, convulsions, seizures, slurred speech, and coma.Other Weather Extremes
While much of the country swelters, late-season snow was forecast for the northern Rockies on June 18. Parts of Montana and north-central Idaho were under a winter storm warning, with as much as 6 inches of heavy, wet snow expected in the mountains around Missoula, Montana.As much as 20 inches was predicted for higher elevations around Glacier National Park.
The intense flooding from heavy rains continued to dissipate in southern Florida, where some areas in and around Miami and Fort Lauderdale were left underwater in recent days as storms dumped up to 20 inches.
That unnamed storm system coincided with the early start of hurricane season, which this year is forecast by private and federal weather officials to be a relatively active one.
