This week will start off on the cooler side with very low humidity. More typical July weather will follow for the rest of the week with warming temperatures and increasing humidity. Storm chances will also increase once again late this week. Overall, it will be a very July-like week, which isn't surprising given the date.
MONDAY
On Monday, the low pressure system that brought showers and storms over the weekend remains to New England's east. Without any major blocking in place, this system will continue to steadily pull away. The trough will allow a cold pool to move into New England today, which will produce afternoon clouds and spot showers. A vast majority in New England will remain dry wire to wire today. Temperatures and humidity will be much lower than Sunday in the post-cold front air mass.

TUESDAY & WEDNESDAY
The general pattern we've been in over the last week continues with highs and lows trading places. High pressure will slide across New England for Tuesday and Wednesday, which will bring quiet and seasonable conditions, with partly cloudy to mostly sunny skies and 80s dominating.

The high pressure will likely be overhead Tuesday afternoon through Wednesday morning before sliding offshore later in the day. This will initiate a more southerly flow with temperatures and humidity trending back up. As the high pressure continues to move offshore, a warm front will approach New England Wednesday night. This front will likely trigger some overnight showers Wednesday night into Thursday morning.

THURSDAY
Heading into the fourth of July, New England will be back into the warm sector as the warm front clears the region. This will reintroduce hotter, more humid weather back into New England. This will also allow some increase in thunderstorm chances. As of now, any shower/storm activity during the day looks to be isolated at best with a majority of the region staying dry for Independence day. It will be a very summery day overall with highs well into the 80s to low 90s.
FRIDAY & WEEKEND
This weekend will likely feature a series of frontal boundaries crossing the region. A cold front will cross the region late Thursday into Friday morning. This front may slow down or stall in southern New England as high pressure remains offshore. This will lead to times of increased clouds along with scattered showers and storms. With that said, washout potential is low and there will likely be more dry hours than wet hours through the weekend.
The higher storm chances will be on Saturday with a cold front looking to cross New England later in the day into Sunday. Temperatures will remain high over the weekend along with higher humidity, especially for Saturday.
