MAINE, USA — Put your A/C units in the windows and get ready to switch the heat pumps over...

After what seems like weeks of gloom and doom, things are about to change drastically in the weather pattern. The temperature outlook takes us from barely 70 degrees to start this week to a run for 90 in a few days. Some say we get three days of Summer ... hard to argue with that based on the current forecast.

The big change in the weather is courtesy of a big ridge of high pressure that moves in from the northwest by Thursday.

The “H” on the map will move to our south and east on Friday and allow humidity to pump into Maine from a southwest breeze.

Dewpoints (the measure of moisture in the air) will skyrocket into the 60s and 70s by the end of the week.

If you add the air temps that will at least be in the 80s…

…to the dewpoint temps in the 60s and 70s, we will see a heat index of around 90 degrees statewide (except for the immediate coastline).

It’s time to get the A/C units in the windows (if you are lucky enough to have one).

Before I let you go, I will note that the ridge is forecast to break down by the weekend with rain in the forecast…oh and if you don't like heat, you still have some time...Juneteenth into the next few days will be 60s and 70s.
