Today: warm & muggy, chance for rain/storms late... then big changes for the weekend!

Posted: Updated:
HARTFORD, CT (WFSB) -

AFTERNOON UPDATE...

With the exception of some scattered showers, the afternoon across CT will feature a mostly cloudy sky.  Due to this, temperatures will not hit 90 today… so a May heatwave is no longer a possibility.  For the evening commute, there could be showers in the state, but there very likely could be a lull before a cold front arrives. 

Storms fire up to our northwest later today, in advance of the cold front.  As the line/front heads in our direction, arriving after the sun sets (10p-midnight), any storms should diminish greatly, in coverage and intensity (to the point where we may just have a final round of rain, perhaps just a few rumbles of thunder). 

Behind the front as it stalls offshore, we trend cooler but still above average Saturday (mid-70s)... the humidity will dramatically drop, as dew point values go into the 40s/30s!  While the first half of the weekend is dry, showers will still be possible Sunday as a wave rides along the front lurking nearby.  Sunday will be even cooler than Saturday, with highs in the 60s.

Next week is on track to feature dry weather… and after a seasonably cool start, temps rebound nicely by mid-week!

RECORD BREAKING HEAT YESTERDAY!

We had another day of 90-degree heat in Connecticut!  This time, a record was broken at Bradley International Airport in Windsor Locks when the temperature peaked at 94 degrees.  The previous record was 93 degrees, set on May 3rd in 2001.  The afternoon high in Bridgeport was 83 degrees, which fell short of the May 3rd record by 3 degrees.   The humidity was higher yesterday, but still not too bad with dew point temperatures mostly in the 50s this afternoon.  A few showers moved into the state yesterday afternoon.

FRIDAY…

A low pressure system will track to the north of New England today and tonight.  The trailing cold front will pass through Connecticut tonight.  That means we will be in the warm air sector throughout the daytime hours.  We are forecasting highs in the 80s with moderate levels of humidity.  Should we get enough sunshine, temperatures could reach 90 degrees.  If that happens at Bradley International Airport, we will have our first heat wave of 2018.  For now, we are forecasting a high of 88, which is quite close!  Once again, there is a chance for a strong to potentially severe thunderstorm.  Perhaps the best chance for a shower or storm will come tonight when the cold front moves through. 

THE WEEKEND…

The cold front will settle to the south of New England tomorrow.  Therefore, we expect a dry, slightly cooler day with mostly sunny skies and highs in the upper 70s.  The humidity will return to much more comfortable levels.  Tomorrow will be the better of the 2 weekend days for outdoor activities.

A wave of low pressure will form on the front Saturday night and Sunday.  Therefore, there is a good chance for showers during the second half of the weekend.  With abundant cloud cover and showers, Sunday should be cooler with highs in the mid to upper 60s.

NEXT WEEK…

A dry, cool air mass will settle into all of New England on Monday.  We are forecasting a partly to mostly sunny day, but highs will only be in the 60s.  The combination of clear skies and light winds will allow temperatures to dip into the 30s and lower 40s Monday night.

With high pressure the dominant weather feature, Tuesday and Wednesday will feature some gorgeous weather!  Tuesday will be sunny with highs 70-75.  The mercury will dip into the 40s Tuesday night thanks to clear skies and light winds.  Wednesday will be sunny with highs in the middle to upper 70s.  The humidity will remain comfortably low both Tuesday and Wednesday.

Unsettled weather will surround New England on Thursday, but for now we are keeping our weather dry.  We are forecasting partly sunny skies and highs near 80 degrees away from the coast.

APRIL RECAP…

April 2018 goes down in the record books as a cool and wet month for the Hartford Area.  The average temperature for the 30-day period is 44.0° …this is 5.5° below average and falls into 6th place for coolest Aprils since records have been kept.  On the precipitation front, 5.55” fell (rain, and includes any frozen precip’s liquid equivalent), that means the month ends with a 1.82” surplus.  With regard specifically to snow, 7.6” was measured… that’s a 6.2” surplus.
