It’s been a humid week and quite warm as well.  This is, on average, the hottest period of the year and it stands to reason we’d see these warm readings.  An upper level system with showers and storms has now moved east overnight and we are seeing drier air slowly filter in from the north and west.

Friday is also another very warm and sunny day. What you will notice is the air becoming drier as the day progresses in spite of rising temperatures.  The drier air will be with us for a cooler stretch of weather ahead.  You can see the dry air arriving as the dewpoints fall below.  Later this weekend, as showers arrive, it will become more humid again, but not as bad as the past few days.

Drier air filters in Friday, lowering dewpoints bring drier air to the region.

Summery Saturday

Saturday continues to be warm, but less humid.  You should expect sunshine blended with clouds and highs will be in the 80s.  High tide, for those of you headed to the beach, occurs during the late morning.  Winds will be quite light – not great for sailing.  This is the day to head to the beach if you are  trying to choose between Saturday and Sunday.

Clouds, late day showers come back Sunday

A weather system moving in Sunday will return clouds to the area and limit the sunshine.  Just when or if the showers arrive is still a question.  Some overnight showers touch southernmost Maine.  The bulk of the morning will be dry and we could see a rain-free afternoon as well.  Showers are more likely later in the evening and overnight.  Highs will remain under 80 and some coastal towns will likely stay in the low to mid-70s with an onshore breeze.

Look for warm readings on Saturday.

Final week of July weather

The final week of the month looks to be cooler than average with an unsettled period to start.  We won’t see a washout Monday or Tuesday, but there is a chance of showers.  The middle of the week looks really nice with sunshine and pleasantly warm temperatures.  That nice weather will last for a few days. The weather for the final weekend of July is still too far out to accurately predict.
