A chance for an isolated PM shower, also a break from 90° heat!

Posted: Updated:


The front that brought heavy rain rumbles of thunder to parts of the state last night and early this morning has cleared CT.  Behind it, some lingering instability that could create isolated showers later this afternoon with the daytime heating.  Instead of reaching the 90s, like the past 2 days, highs will be between 80 and 85.

The rest of the week will be dry and sun-filled.  Tomorrow we’ll start out on a cool note (upper 50s/lower 60s), then top out again in the low/mid-80s.  A warmer airmass builds in as we close out the week and head into the weekend. 

For the weekend, the heat ramps up and eventually the humidity does as well.  Saturday still looks to be dry.  Sunday, an isolated shower/storm can’t be ruled out.  Same goes for next Monday and Tuesday, hit and miss – not a washout.  If temps reach/exceed 90 Sun-Mon-Tue, we’ll have our 2nd heat wave of 2018.   Chances for rain/storms go up late Tuesday into Wednesday with the arrival of a cold front.

TODAY, 7/11/18…

In the wake of a cold front that's moving through this morning, today will feature cooler weather with high temperatures ranging from 80 to 85 – more in line with what is considered ‘normal’ by mid-July standards.  The wind will have a northerly component to it, so coastal communities will be as warm as inland areas.  While most of the day will be dry in many towns, an isolated shower can’t be ruled out… compliments of lingering instability with cooler air aloft, combining with daytime heating.


High pressure builds in for the remainder of the week, this means storm-free weather with plentiful sunshine.  Tomorrow will be quite comfortable, starting out near 60 then warming to the low and mid-80s.  Friday features a return to warmer weather, fortunately the humidity remains fairly low. 

Meanwhile, Chris has strengthened to a Hurricane (our 2nd one of the season, to date).  After being stationary for nearly a day, the system is now to the east of Virginia, moving to the northeast.  It is forecast to continue on this trajectory through the end of the week.  On this course, Chris will stay well offshore from Southern New England today and tomorrow (by several hundreds miles).  The greatest impact will be on the marine community and marine life.  Meanwhile for those along ocean/Atlantic facing coastline, expect larger surf/swells and rip currents.


Saturday still looks to be dry and hot (close to 90 inland).  However, the humidity appears to increase over the course of the weekend.  Sunday should be several degrees hotter, likely reaching or exceeding 90 degrees inland.  Additionally, there will be a slight chance for isolated showers or storms (but it does not appear to be a washout, most of the state remains dry).  The same type of threat for rain and storms continues into Monday of next week with temperatures once again getting to that 90 degree mark or higher away from The Sound.  A repeat performance can be expected for Tuesday.

The first heat wave of 2018 lasted 7 days.  Here’s the breakdown by day, with high temperature: 

Friday June 29, 90°; Saturday June 30, 93°; Sunday July 1, 98°; Monday July 2, 95°; Tuesday July 3, 95°; Wednesday July 4, 94°; Thursday July 5, 92°.


The longest heat waves on record in Connecticut lasted a total of 10 days.  There was a 10-day heat wave in the summer of 1995 from July 24th through August 2nd.  There was another 10-day heat wave in the summer of 2016 that lasted from July 21st through July 30th.

The most intense heat wave was in July of 1991 when we had 3 consecutive days of 100-degree heat!  It was 100° on the 19th, 100° on the 20th, and 101° on the 21st!
