Hot, humid air spurs heat warnings across Maine

In some areas, 90-degree temperatures could remain lingering into Friday, he said, noting Saturday then would be the best bet.

A classic summer heat wave will develop in San Diego County on Friday and Saturday with temperatures hitting 80 degrees at-or-near the coast and the upper 90s and low 100s across inland valleys, says the National Weather Service.

Some inland areas of ME, such as Fryeburg, could find themselves in a heat wave, which is defined as three consecutive days of 90-degree temperatures. In fact, Heat Advisories and an Air Quality Alert have again been posted for today as we're experiencing similar conditions to what we experienced Yesterday. The timing will have a big impact on the timing of thunderstorms and the potential for severe weather.

Ricketts said that the air temperatures all over the region are in the 90s, with heat indexes between 100 and 113.

For Wednesday, the 4 of July, we expect more of the same: heat and humidity, but an even lesser chance for an isolated storm.


Greenalalt said the heat may linger into Sunday and could prompt another advisory if the humidity stays up to keep the index over 100 degrees.

Experts warn residents to be "heat smart". Hot weather, especially long duration heat waves, is surprisingly high on the list of most unsafe types of weather in terms of injuries or deaths each year.

Today was our heat wave day five, with the fourth day in a row of highs in the mid 90s and a dangerously high heat index of 109 in Philadelphia. Partly sunny, with a high near 89. The in the afternoon and evening some pop-up storm chances will be around. While mother nature may have her own fireworks display, it's still nothing to cancel the outdoor plans over at this point, just have a backup plan.

That strong heat dome should finally start to break down slightly by the latter half of next week. Highs next weekend will average in the mid and upper 80s, with lows in the upper 60s and low 70s. "It will go from hot and humid to a little bit cooler, a little bit drier, or more seasonal, somewhere in the low 80s".
