After a prolonged stretch of very unsettled weather, New England will be getting a blissful break (for the most part) this week. Well, until the end of the week. That's when things could turn wet again.
MONDAY
After the region experienced its coolest morning in over a month, the day will warm up nicely across southern and central New England, with seasonable afternoon highs. A cold front will drop into northern New England in the afternoon, which will keep these areas cooler. Highs will remain in the low 70s in the valleys with temperatures not breaking out of the 60s across mountain towns and northern Maine.
Isolated to scattered storms erupting across northern New England around mid-afternoon:
This cold front will allow scattered showers and storms to develop, mainly across northern New England, this afternoon. As the afternoon progresses to the evening, some isolated showers and storms will break out across southern New England as the front continues to push south. These showers will truly be isolated, with most across southern New England remaining dry all day.
TUESDAY & WEDNESDAY
High pressure will move in and dominate the middle of the week. This will lead to three main things: quiet weather, (very) low humidity and cool nights. First off, for the first time in a while, ALL of New England is looking dry these two days. Second, dew points will remain at very low levels. Levels not seen in quite some time. Dew points will hang around the low 40s to low 50s. That is to say there will be absolutely no humidity felt. This is a massive change to the extremely humid summer New England has experienced.
Lastly, this high pressure will create generally clear skies overnight. These clear skies will allow temperatures to bottom out. With low dew points, temperatures will have nothing stopping them from crashing to the mid 40s in northern areas and the higher elevations of southern New England to mid 50s for southern areas. This is a good 10-15 degrees below average for morning lows.
Daytime highs will warm up nicely once the sun comes out. Southern New England will be looking at highs in the mid 70s to low 80s. Northern New England will remain rather cool during these days, with highs topping out in the upper 60s to mid 70s.
High pressure just to New England's west on Wednesday. This high pressure will slide eastward across New England during the middle of the week:
THURSDAY
On Thursday, New England will begin entering back into familiar territory. Winds are looking to shift from a northerly direction to a southerly one. This will allow temperatures to climb higher than it has up to this point this week. Highs will likely top out in the upper 70s north to mid 80s south.
This southerly flow will also allow dew points and humidity to begin climbing once again. An increase in humidity will lead to overnight lows climbing back to seasonable levels, in the 60s rather than the 40s and 50s. The day is looking increasingly likely to be dry and overall a very nice summer day. The next system will begin approaching, so we'll have to watch for some potential showers and/or storms late in the day, mainly in northern areas, but, again, Thursday has been trending drier, particularly for southern areas.
FRIDAY
The next system will be arriving. New England will likely end up in the "warm sector" of the system. This means more humid weather, increasing clouds and scattered showers and storms. The system will likely drag a cold front across the region, leading to another round of afternoon thunderstorms. Just how potent these storms can get and how much of the day is wet vs dry remains to be seen. High temperatures are a bit of a wild card for Friday. Right now, it looks like increased cloud cover and rain will limit highs to the 70s.
WEEKEND
What happens this weekend, particularly on Saturday, will depend on the timing of Friday's storm system. New England won't be in the clear until the cold front completely clears the region. There could be another round of storms and showers Saturday afternoon, although not to the extent of Friday. This is far from locked in as, again, timing of the front needs to be hammered down.
The front does look to clear by Sunday, putting New England back into a northwest flow. This would once again lead to a lowering of humidity with full summer heat remaining out of the picture.
