Summer arrives June 20th at 7:09 PM and the season will kick off with record breaking heat and a heat wave with three days in a row of temperatures in the 90s! The dramatic change begins Wednesday as blow torch southwesterly winds pump in the sizzling heat and humidity that has been roasting much of the nation.
A Heat Advisory is in effect for parts of central and western Connecticut from noon to 8 PM Wednesday. A Heat Advisory is issued when the combination of heat and humidity create a situation where heat illness is possible. The heat index will be between 99-104 degrees for inland Connecticut. That’s how hot it will feel outside!
An Air Quality Alert is in effect for southern Connecticut including Fairfield, New Haven, Middlesex, and New London Counties. Ground level ozone will be at unhealthy levels for sensitive groups from 11 AM to 11 PM Wednesday. Those with respiratory problems should limit the amount of time spent outside.
Temperatures both Wednesday and Thursday will range between 95-100 degrees inland, 90-95 along the shoreline. The shoreline temperature is a little trickier. Any shift in wind over the Long Island Sound will keep temperatures cooler than inland areas. But if the wind stays westerly, temperatures will skyrocket! The humidity will be higher on Wednesday but temperatures will be slightly higher Thursday.
How rare is this June heat? Connecticut has only hit 100 degrees in June twice on record (records date back to 1905). This could also be the earliest 100 degree day on record. The record high temperature in the greater Hartford area is 96 degrees both Wednesday and Thursday. The record high temperature in Bridgeport is 93 degrees on Wednesday and 95 degrees on Thursday. Those records will be challenged or broken!
Friday also looks hot but not as oppressive with temperatures near 90. A cold front will likely break the heat late day and may be accompanied by thunderstorms.
