Forecast: Nice Weekend Ahead — And A 'Super Moon' Eclipse Sunday

This article is more than 5 years old.

There are all sorts of techniques and methods to forecasting. One such way is called persistence. This type of forecasting assumes the weather will be the same as the day before.

Here in New England, this means of predicting the weather doesn’t work very well, because our weather typically changes day to day.

I am going to use persistence to forecast the weather this weekend. The past 10 days have featured high pressure, keeping any rain at bay, along with comfortable levels of humidity and pleasant temperatures. This pattern of "what you see is what you get" is going to continue through the weekend, but will undergo some changes early next week.

As these areas of high pressure move out of Canada, they bring lots of dry air and pleasant temperatures. The winds around these highs also circulate clockwise. This weekend one will bring a flow of air off the ocean.

This means temperatures will be pleasantly cool or mild, depending on your perspective. There won’t be much in the way of clouds Friday or Saturday but they will increase on Sunday.

Sunday’s clouds may impact the viewing of the lunar eclipse Sunday evening. The eclipse is going to occur during the full moon and will be visible in its entirety. It starts around 9 p.m and will continue for just about an hour and a quarter. You might hear the term “super moon” this weekend as well. This is nothing more than the moon making its closest pass of the Earth. The moon does appear bigger, and having an eclipse during the time the moon is making its closet path to Earth is unusual.


Friday: Mostly sunny, highs 66-72.

Friday night: Mostly clear, lows 45-50.

Saturday: Sunny, with a high 65-70.

Sunday: Mostly sunny, with a high near 70.

Monday: Mostly cloudy, with a high in the lower 70s.

Tuesday: Partly sunny, with a high 75-80.
