After some much-needed rain on Tuesday, temperatures should rise into the 90s later in the week.

Chief Meteorologist Bruce DePrest said the risk of a shower Tuesday evening is very low. Temperatures will fall back through the 80s and then into the 70s over night.

Patchy fog is possible after midnight.

The heat turns up on Wednesday.

DePrest said in order to have an official heat wave, there must be at least three consecutive days with high temps of at least 90 degrees.

DePrest said "the last time the temperature reached 90 degrees at Bradley International Airport was all the way back on May 29 when the high was 91 degrees. That will change tomorrow."

An air quality alert was issued for Fairfield, New Haven, Middlesex and New London counties on Wednesday until 11 p.m. on Thursday. There should be enough sun to boost temperatures into the 80s.

“We are expecting air quality that will impact all of our citizens especially the most vulnerable residents - children, the elderly and those with respiratory disease such as asthma,” said Department of Energy and Environmental Protection Commissioner Robert Klee. “It will also impact healthy adults working or exercising outdoors – to minimize health impacts while working outdoors avoid prolonged strenuous activity and best if you exercise before noon or after 8 p.m.”  

“For the thousands of children and adults in Connecticut who live with asthma, COPD and other respiratory conditions, unhealthy air on hot summer days can trigger or worsen respiratory ailments,” said Department of Public Health Commissioner Dr. Raul Pino. “On poor air quality days, people with respiratory conditions should avoid prolonged periods of time outdoors by staying in cool, air conditioned indoor environments. If exposure to the outdoors is unavoidable, make sure rescue inhalers and medications are readily available and avoid overexertion while outside.” 

Temperatures will be in the mid-90s on Wednesday in many locations away from the coast.

While Wednesday will be hot, the humidity will be moderate, but the air quality is expected to be poor.

There will be more humidity on Thursday and temperatures should reach 90 degrees or higher once again.

Most of the day will be partly to mostly sunny, but there is a risk of a shower or thunderstorm in the late afternoon or evening.

"The front will be the focus of more scattered shower and thunderstorm development on Friday. The heat wave could become official on Friday with highs near 90 degrees, but how high temperatures go will greatly depend on the location of the front," DePrest said.

When air pollution levels are predicted to be “unhealthy for sensitive groups” DEEP recommends:

  • Conserving electricity by setting air conditioners to 78o;
  • “Wait ‘til 8” to use energy intensive appliances like washing machines, dryers and dishwashers;
  • Refueling your lawn mower and cutting the grass before noon;
  • Driving less by carpooling, vanpooling or using public transit;
  • Telecommuting if possible; and
  • Refueling your vehicle after dusk and never idling a vehicle unnecessarily.

We also need long term actions to get to the root of our air pollution problem in the United States. DEEP recommends you also consider these long term energy reducing strategies:

  • Make your home or business as energy efficient as possible – this drives down air pollution and puts money back in your pocket;
  • Cars and trucks cause over half our air pollution, so consider driving an electric vehicle; and
  • Consider investing in renewable energy like solar electric.
