AccuWeather.com reports the heat wave that occurred in late April across much of the East may ultimately be the hottest and longest duration of heat across much of the East this year. The core of the coldest weather will become anchored over the Ohio Valley and Great Lakes, which means temperatures in the 70s and 80s, and few days topping out in the 90s. With that said, we expect areas from southern New England into the Carolinas to have exceptionally high humidity this summer. So while it might not be hot temperature-wise, the humidity will still make it feel uncomfortable.
The overall jet stream pattern will have a trough of low pressure in the East and a ridge of high pressure in the West. The corridor from the northern Plains through the Great Lakes, Ohio Valley and Northeast will have frequent rounds of thunderstorms. No area may become too wet, as the rounds of storms will just continue through the region and not stay in any one location. The good news with that means areas from the Midwest through the Great Lakes and Northeast will have times when dry, cool air masses settle in, bringing comfortable weather conditions.
The South will have a normal summer weather pattern. Temperatures and the extent of the humidity will be normal. That means temperatures in the 80s and 90s. The normal bought of afternoon thunderstorms will occur as well.
The core of the hot weather will be located across much of the West. Places like Salt Lake City will have numerous days with highs in the 90s and 100s. The Desert Southwest will be hot as well, with temperatures well into the 100s. The heat will make appearances in the Northwest cities like Seattle and Portland, Ore. It's not out of the question that temperatures reach into the 90s for a few days before cooling returns. No extended period of hot weather is expected.
California will be hot and dry this summer with the normal coastal low clouds and fog sticking around through the midday hours. In some cases, the low clouds may take longer to burn off due to the extreme heat in the
deserts.
