Heat index values likely to top 100 today

02 Juillet 2018

EXCESSIVE HEAT WARNING for Jefferson, Lewis, and Northwestern St. Lawrence County from Sunday at noon until Monday at 10pm.

Hot and increasingly humid conditions are expected through the end of the weekend as a Bermuda high-pressure type system sits off the East Coast over the western Atlantic.

Saturday will see afternoon highs in the lower to mid 90s, with temperatures slow to fall in the evening and unlikely to drop below 90 degrees, according to the NWS.

The hottest day of the year is on tap for us on Saturday.

The brunt of the recent heat spell arrives Thursday in Kansas City, but don't expect too much relief once the sun goes down.

Forecasters say it will be warm and muggy along the ME coast, but still cooler than communities farther inland. Heat indices rose well above the air temperatures today, with some even eclipsing 100 at times.

The heat will continue through next week, the weather service said: "Peak heat index values Tuesday through Thursday will likely range from the 90s to near 100 each day".

The National Weather Service has issued an Excessive Heat Warning, which is in effect from 8 a.m. Sunday to 8 p.m. Monday. Heat index values as high as 99. High: Low-mid 90s. Mid 80s shore. A few locations in northern Indiana and near the Indiana/Illinois state line may cross in to the lower 100°s.

"We'll be looking if a couple areas get into the upper 80s and break it", Priante said.

90s are in our forecast nearly off of next week with perhaps a slight cool down on Friday. This is especially true if they do not live in an air conditioned home. There's going to be a chance for a thunderstorm on Friday morning with a warm front lifting north.

The normal high for much of July is around 90°.

Saturday's record high is 100 degrees set in 1931. "There's a 30 percent chance of an afternoon shower or thunderstorm".
