Our 3rd heat wave is official, if it continues; plus chances for rain/storms...

Posted: Updated:


Hot and humid today, again… but not *as* extreme as the past couple of days.  Regardless, a Heat Advisory remains up for much of CT until 6pm.

Like yesterday, we’ll run the risk for isolated storms from mid-afternoon through the evening hours.  Heavy rain, a gusty wind, and lightning can be expected in storms that do develop.  Tomorrow, there is still a chance for shower or storm, but pretty a slim one.  The humidity, however, will decrease a bit as the day progresses.  Highs today may come close to 90, if we hit that magic number at Windsor Locks (where the official records are kept for the Hartford area), then we'll be on day #4 of our 3rd heat wave of 2018!

Friday the humidity will be fairly comfortably, but it will still be hot.  We’ll end the week dry with sunshine.

The weekend still appears to be unsettled, more so Saturday than Sunday.  It will also be warm and muggy.

This pattern continues into early next week……

A HEAT ADVISORY remains in effect state wide (except Northern Litchfield County) until 6:00 pm this evening.  


The temperature reached 90 just before Noon yesterday, our 3rd day consecutively to reach/exceed 90°, therefore we officially have our 3rd heat wave of 2018!  Yesterday also marked our 23rd 90 degree (or higher) day for the greater Hartford area. 

The high at Windsor Locks yesterday was 93°, 7 away from the record for this date.  In Bridgeport, the high was 89°, 5 away from the record.  Regardless, with dew point values in the low and mid-70s, the heat index topped out near/above 100 in many towns mid-afternoon!


Today will be quite warm and continued humid.  High temperatures will be dependent upon sunshine, likely reaching the mid and upper 80s along the shoreline… and between 85 and 90 inland.  If the temperature is able to reach 90 at Windsor Locks, then our heat wave will go into day #4!  The heat index will top out in the mid-90s with dew point values in the low to mid-70s (not quite *as* bad as yesterday afternoon, but still pretty unbearable).

As a front gets closer to Southern New England this afternoon, from the northwest, we’ll run the risk for more showers and thunderstorms, some of which could be strong, so please keep your eyes to the skies and if they look threatening, please head indoors.   


A few showers could linger into early tomorrow morning as the front drifts away to the east of Connecticut.  During the afternoon, we can’t rule out an isolated shower or storm with lingering instability and daytime heating.  Highs will be in the 80s to right around 90 degrees.  However, the humidity should drop to slightly more comfortable levels (dew point values in the 60s).  With temperatures hovering near 90 degrees, the heat wave could extend to a 5th day, but that is highly uncertain at this point.  Friday is looking good!  Temps are expected to get close to 90 degrees once again under mostly sunny skies.  Humidity levels should be fairly comfortable.


A warm front and an area of low pressure will be positioned just to the south of New England on Saturday.  Therefore, clouds and showers and perhaps a few thunderstorms are expected to develop.  Clouds should keep temperatures in the 80s for highs and the air will be humid.  The unsettled weather should shift to the east of Southern New England on Sunday.  While a lingering shower can’t be ruled out especially in Eastern Connecticut, most of the day should be dry.  We are forecasting a partly sunny sky and highs in the upper 80s.


An approaching warm front could send a few showers our way by late Monday.  Otherwise, we can expect partly sunny skies with highs 85-90.  Tuesday, as of now, looks a bit unsettled with a chance for rain and storms.

Saturday morning began with stormy weather that included the fifth confirmed, EF- rated tornado in Connecticut for the year.  The National Weather Service has reported that it was a weak and small tornado, with a width of eight yards and a path length of only one block with maximum wind of 80 MPH.  It did damage to a few cornfields and an oak tree before lifting back into the sky.  The same storm produced a “high end EF-1 tornado” that caused considerable damage to downtown Webster, Massachusetts.

JULY 2018…

The month of July is over and there were impressive statistics!  The average temperature at Bradley International Airport will come in at or close to 76.1 degrees, which is 2.5 degrees warmer than normal.  That means this July will be the 8th warmest on record for the Greater Hartford Area, and records date back to 1905.  That is quite impressive!  We had 11 days that were 90 degrees or higher.  The hottest day was July 1st when the high temperature was 98 degrees at Bradley.  Temperatures were in the 90s the first 5 days of July, concluding a heat wave (which began in late June) that lasted a total of 7 days.

The first half of July was dry, but the second half was quite wet.  Total rainfall for the month was 6.39”, which is 2.21” above normal.
