Another nice push of air from Canada is helping New England stay mostly dry this week as it stays on the cooler side the next 48 hours, then warms into our last summer weekend of 2019.
The flow from Canada also protects us from any tropical storms, like Hurricane Humberto out over the open water. It is expected to intensify as it nears Bermuda through Wednesday. Another tropical system has moved into Texas with flooding rain possible near Houston and points south.
For us, we have a good amount of sunshine mixing with fair weather clouds Tuesday afternoon. A few raindrops may come from the sky in Maine and eastern Massachusetts. Western New England will hardly have a cloud in the sky. High temperatures will be in the 60s to low 70s well inland. Wind is from the north and east at 5 to 15 mph.

Clouds in eastern New England are associated with the push of cooler air moving in from north to south Tuesday night and Wednesday.
With the clearing sky Tuesday night, we expect temperatures drop into the 40s and 50s south, and 30s and 40s north, with a chance of frost and freeze for many parts of northern New England.
Wednesday is similar to Tuesday; we start out with a blue sky then many clouds build up, especially in eastern New England. High temperatures will be in the 60s for the most part but in the 50s in parts of Maine.
Low temperature Wednesday night will be the coldest since last spring: 30s and 20s north, 40s and 50s south.
A warming trend begins Thursday as high-pressure starts to move east. There will be plenty of sunshine and a high temperature of about 70 degrees.
That high-pressure system does not move much, but we’re going to see warmer air in southeastern Canada that will come into the region this weekend. Expect plenty of sunshine Friday through Sunday with a high temperature back into the 80s. It will be cooler at the coast.
The autumnal equinox is next Monday and we may actually be in the mid-80s widespread. However, we may face a chance of a thunderstorm and some cooler air may try and come in from the west and north after the equinox next week.
