Heat and humidity increase over the weekend along with a chance for showers and thunderstorms

6/25/2021

Warm temperatures and scattered showers for Saturday

As coastal fog burns off early and daytime heating begins, Saturday will mark the start of a warming trend across the state continuing into next week. Temperatures will be in the 70’s although a few interior locations, especially towards the south are likely to reach the 80’s. The exception will be along the coast where a sea breeze will set up, keeping temperatures cooler. As pockets of shortwave energy at 500mb pass through the area, showers will develop in the afternoon primarily in the northern regions. These showers, however, will likely not bring any significant relief to ongoing drought conditions.

Hot and humid on Sunday with scattered showers and thunderstorms

Temperatures could surpass 90 in the southern interior regions while farther north temperatures are likely to stay in the 70’s. A sea breeze will keep the coast on the cooler side with temperatures in the 70’s along the southern coast and possibly below 70 along the northern coast. Dewpoints as high as 70 in some locations will make the air uncomfortable where temperatures are the warmest. As pockets of shortwave energy continue to traverse the area, scattered showers and thunderstorms will linger throughout the day towards the north. Otherwise, the region should see a mix of sun and clouds to the north and mostly sunny skies to the south. Overnight, there is the possibility for some fog to develop around the MidCoast region

A hot and humid start to the week

The pattern of hot and humid weather continues into next week with temperatures looking to be even hotter than over the weekend, potentially reaching the mid-90’s in the southern interior regions on Monday and Tuesday. Temperatures will again be cooler towards the north, possibly not exceeding 80. Showers and thunderstorms will be present across much of Maine and the chance for an isolated severe storm exists. A weaker sea breeze may allow the southern coast to heat up and stay in the 80’s as winds will be pushing hot, continental air offshore. Conditions will also be very humid as dewpoints stay in the 60’s and even 70’s in a few places on Monday before becoming more comfortable by the end of the day on Tuesday.

Some scattered storms will move through the area on Monday. The possibility of a severe storm or two cannot be ruled out.

More warm weather for the remainder of next week with scattered showers and thunderstorms

Temperatures will remain warm but not quite as hot as the beginning of next week. Humidity should also not be quite as stifling as Monday and Tuesday. Scattered showers and thunderstorms will be present across the region each day and some may persist into the overnight hours. Also look out for the chance of a severe storm or two.

Temperature outlook for the weekend and next week

Temperatures increasing through Monday making for some hot conditions. Temperatures trend slightly cooler towards the end of next week.

Lightning safety when camping

Going camping? You are NOT safe from lightning in a tent. Avoid standing under trees. Find a sturdy building for shelter. If you can’t find one and are near your hard-topped vehicle, shelter in it with the windows up.
