Showers and even some embedded heavy downpours will continue to move south to north this evening. There will be breaks of sunshine in places and also some periods of dry weather.

What about the weekend? That’s the big question I am getting over the past few days. The reality is the second to last weekend in August isn’t going to provide us with a bright blue sky and seasonably warm temperatures. However, it’s not going to be a total washout either. I believe one of the best ways to describe this weekend, simply unsettled.

Tonight could very well turn out to be one of the wetter periods of the entire weekend three days for some of us.

There’s a lot going on meteorologically this weekend and for sun worshipers, it’s not looking great. The satellite loop below is from this afternoon. There are some interesting things we can learn from watching this loop. I put a still image under the loop and circled the points of interest.

To our west, there is a cold front. This front isn’t ever really going to pass through, rather it’s going to sit over us this weekend and eventually wash out. This term means the air on each side of the front, while different now, will merge together and leave us with one humid air mass.

Fronts “wash out” when the push of air behind the front isn’t very strong. As they slow down the boundary between the two air masses becomes less and less defined. The boundary doesn’t entirely disappear, but can act as a focal point for showers. This is the problem this weekend. As the cold front to our west inches eastward this will increase the chances for showers in eastern New England.

Another factor in the forecast is an area of low pressure around Bermuda. Moisture from this system can be pulled northward into our area as it interacts with the cold front. Even some of the heavy downpours this morning may have some tropical connection.

Saturday
Tomorrow with the frontal boundary just off the coast, I expect showers and even thunderstorms to be present on much of the day. It won’t rain everywhere all the time, but if you do get showers they will be heavy and with all the moisture in the air, everything is going to be wet. There may be some breaks of sunshine and it will be warm and humid. If there isn’t thunder, the kids will be fine going swimming, but field and golf games might be difficult with the wet surfaces.

The radar for 10 a.m. tomorrow indicates a widely scattered shower regime, not everyone will be getting wet.

Sunday
There will still be tropical moisture in the air and therefore the chance of showers continues. There will be some sunshine as well mixed with the clouds and any downpours will bring a lot of rain in a shower period of time.

The showers are even less widespread on Sunday.

Monday
The start of the work week with feature a day of continued high humidity, showers and even some thunderstorms with some tropical downpours at times.

Tuesday
A stronger cold front will push the humidity out to sea during the day and into the evening. This will bring an end to this pattern as much drier air greets New Englanders for the middle of next week.
