Ideal weather conditions for the 4th of July!

Posted: Updated:


As I said earlier in the morning forecast, this is a "top ten" best day of the year! At noon the temperatures ranged between 75-80 degrees, while dew point temperatures are ranging between 55 and 60 degrees.  That is so great for the Fourth of July! Get out there and enjoy the wonderful day!


High pressure and dry air set up shop across New England today.  That means a near perfect 4th!  Sunshine is mixing with some puffy fair weather clouds, the air is seasonably warm, the humidity is low, and winds are very light.  Temperatures will reach the low to middle 80s by later this afternoon and dew point temperatures will be in the 50s.  A light sea breeze is developing and that means the shoreline will be a bit cooler with highs near 80 degrees.  It’s a great day for the beach!  By the way, the 4th of July last year was quite warm with a high of 88 degrees at Windsor Locks.

Tonight will be quite comfortable for early July.  The mercury will dip into the 50s to near 60 degrees under a mainly clear sky.


High pressure will be with us again tomorrow, although it will begin to drift to the east of New England.  That means we can expect another winner!  The sky will be partly to mostly sunny as temperatures rise into the low to mid 80s.  The humidity will remain low with dew points in the 50s, perhaps the lower 60s at the coast.

By Thursday, we’ll start to see some changes.  High pressure will move out to sea away from New England and a trough of low pressure (a dip in the jet stream) will develop to the west of New England.  Therefore, we’ll likely see an increase in cloud cover Thursday, but our weather will remain dry through the daytime hours.  Temperatures will reach the low and middle 80s again.  The humidity will rise a little higher due to a light south to southeasterly flow throughout the day.


The trough in the upper regions of the atmosphere will sharpen over the Northeastern States Friday, Friday night, and Saturday morning.  Thus, the risk of showers and thunderstorms will return on Friday.  Plus, the air will be warm and noticeably more humid.  Temperatures will reach the 80s, but it could get even warmer with enough sunshine.

Showers and scattered thunderstorms are likely Friday night as well.  Plus, it will be mild and muggy with lows 65-70.


Showers will probably linger into Saturday morning.  However, the upper level trough will likely lift away to the east of New England during the afternoon.  At the surface, a cold front will pass through the state and a drier northwesterly flow will likely take over during the afternoon.  Therefore, Saturday afternoon is looking better with partly sunny skies.  Highs will be in the middle 80s as the humidity will likely drop to more comfortable levels.

Saturday night will be dry and fairly comfortable with lows 55-65.

For now, it looks like Sunday will be nice as well.  We are forecasting partly sunny skies and highs 80-85.  A south or southwesterly breeze will likely freshen as the day progresses and this flow could bring the return of slightly higher humidity.


The next upper level trough and cold front is forecast to move into the Northeast on Monday.  Thus, showers and scattered thunderstorms are likely along with higher humidity.   High temperatures could be limited to the upper 70s and lower 80s due to abundant cloud cover.

Have a wonderful 4th of July!
