It's a beautiful day- sunshine, low humidity, and mild temperatures!

Posted: Updated:

**Hurricane Irma is gaining strength. Winds have increased to 120mph. Hurricane Warnings have been issued for the Leeward Islands. Hurricane Watches have been issued for Puerto Rico and the US and British Virgin Islands** 


After yesterday's rain and cold temps, today, Labor Day, is looking like a much better day for a trip to the beach or a cookout.  Skies will be mostly sunny, humidity levels will remain low, and there will be a refreshing westerly breeze.  Plus, it will be much warmer than what we have seen over the weekend, with highs reaching the upper 70s and lower 80s. 

The humidity will begin to creep up tonight as our winds turn more southwesterly between high pressure offshore and a cold front to our west.  Low temperatures overnight will fall into the mid to upper 60s.


Although Labor Day is often called the unofficial end of summer, Tuesday will feel very much like a summer day out ahead of our next cold front!  Most of the day will feature partly sunny skies and a gusty southwesterly breeze.  That will bring high temperatures to the middle and upper 80s inland and lower 80s at the shore while dew points climb into the 60s!  The good news is that the breeze should keep it from feeling too oppressive outside.

By late Tuesday afternoon and Tuesday evening, the front will be close enough to bring the chance of showers and thunderstorms.  The storm prediction center has placed NW in the "slight risk" category for severe thunderstorms, and central/southern CT in the "marginal risk." The storms look likely after 5pm, and any that develop have the potential for gusty winds, small hail and heavy downpours.



Wednesday will be a wet day as the front will stall out near us and waves of low pressure begin to ride along it.  This is because the boundary will become parallel to the upper-level steering flow which will be out of the southwest.  Numerous showers and thunderstorms will be present Wednesday, some of which could produce heavy rainfall. 

As for high temperatures, they will greatly depend on exactly where the front gets hung up.  The further west it stalls, the warmer we will be, while a further east stall point would mean cooler temperatures.  Since we are currently expecting the front to be nearby, we are forecasting middle 70s for highs Wednesday and lower 60s for lows Wednesday night.


Thursday’s weather will be similar to Wednesday’s as the front will still be hung up near Connecticut.  That means more showers and thunderstorms with the potential for some heavy rain.  We could end up quite the soaking before the week is over if our computer models are correct, perhaps 1”-3”.  Temperatures will once again depend on the exact position of the front, but we are once again forecasting middle 70s for highs.

By Thursday night the front will finally move east, bringing an end to the rain.  Skies will begin to clear out, the humidity will drop, and temperatures will bottom out in the 50s.



Friday will feature much-improved weather.  The cold front will be long gone as an upper-level low pressure in association with a trough located over the Great Lakes will finally move eastward.  While we cannot rule out an afternoon shower as there will be instability around, we think most of the day will remain dry under partly sunny skies.  It will feel quite comfortable with the mercury reaching the middle and upper 70s and dew points dropping through the 50s.  The normal high at Bradley Airport for September 8th is 78 degrees, so we will likely be very close to that.

Any showers that do develop will end Friday night and skies will clear out.  That will set up a great night for sleeping with lows in the 40s and 50s!

Saturday & Sunday

Nice weather will prevail for next weekend, though there may be an isolated shower or two Saturday afternoon.  However, our computer models disagree on temperatures for next weekend.  The GFS keeps our temperatures mild with highs in the 70s and lows in the upper 40s and lower 50s.  The European and Canadian models, however, have a much stronger push of colder air, which would suggest high temperatures in the 60s and lows in the 40s with 30s in colder spots!

We are leaning toward with the warmer scenario for now, but we will continue to keep you updated as we fine-tune the forecast


We are keeping very close tabs on Hurricane Irma.  Irma is a Category 3 hurricane with winds that have increased to 120 miles per hour.  Irma may strengthen into a Category 4 hurricane over the 24-48 hours and it will be a threat to the Leeward Islands where Hurricane Warnings have been issued. In addition, Hurricane Watches have been issued for Puerto Rico and the US and British Virgin Islands.  Eventually, the storm may be threat the east coast of United States, but the uncertainty regarding this issue cannot be understated.  If it impacts the eastern U.S., the timing would possibly be Monday of next week – a week from now.   Since impacts from the storm are possible here in New England, we will certainly monitor this storm closely!
