Syracuse, N.Y. -- The Midwest and Central Plains will be baking in 100-degree temperatures this week in what meteorologists are calling a "massive heat dome."

It won't be that hot in Upstate New York, but it will be hot.

"For a good chunk of western and Central New York, you're going to be on the fringes of the heat," said Accuweather meteorologist Tom Kines. "I suspect there's going to be a day that gets to 93 or 94, and that's probably going to be Saturday. When you factor in the actual temperature, the humidity and the sunshine, I think it's going to feel like it's in the upper 90s."

Some parts of Upstate New York could see a bona fide heat wave, with three days of high temperatures at or above 90, from Thursday to Saturday.

Kines said the heat will migrate from the Midwest toward the eastern U.S., but the jet stream will trap the hottest air south of New York.

"The heat is going to head toward the (Great) Lakes, then start to dive southward," he said. "It looks like the brunt of the heat is going to be aimed more toward the Mid-Atlantic and the Southeast."

The jet stream will likely flatten out a little Friday into Saturday, and that could let the heat slip in for that 94-degree day.

"We might just get grazed by" the Midwest heat, said Dave Nicosia, a National Weather Service meteorologist. "It won't be the extreme heat like they'll be seeing in the Plains."

Before that hot air moves in, though, Upstate New York is in for a pair of pleasant days Tuesday and Wednesday. Highs will be in the upper 70s, with overnight lows dipping close to upper 50s.
