Things are looking hot this weekend, as temperatures in southern Maine could top 100 degrees on Saturday, according to the National Weather Service.

A warm front will move through early Friday, resulting in warmer and muggier weather. Temperatures will be in the low 80s during the day with chances of afternoon storms in the western part of the state, according to the weather service.

Saturday will be “dangerously hot,” with temperatures in the high 80s up north, low 90s Down East and 100s in southern Maine. “The problem will be the muggy airmass,” the weather service said.

Meteorologists in the National Weather Service’s Caribou office report a slight chance of thunderstorms on Saturday and said “models seem to be backing off on storm chances.”

The weather should be a bit less muggy come Sunday, with near average temperatures and low humidity in the first half of next week.

Over the weekend, limit strenuous activity, find shade, take breaks and stay hydrated. Make sure you check on those without air conditioning, elderly people and sick people, according to the weather service.

Heatstroke is a threat for livestock and pets. Make sure animals have access to water, are not overexerting themselves, are in well-ventilated areas and have ways to cool down — such as sprinkler systems, according to the Maine Department of Agriculture, Conservation and Forestry.

The weather service advises that it is never safe to leave a toddler, person with disabilities or pet in a locked car, regardless of the season. Fifty-two children in the U.S. died from heat stroke in cars last year.
