For the third consecutive day, Connecticut is under a heat advisory.

Hot temperatures and high humidity will make it feel like 96 degrees, the National Weather Service says.

The advisory is in effect from 1 to 7 p.m.

High temperatures of up to 87 degrees are expected along the Connecticut shoreline. Warmest temperatures are expected inland where it could reach 92.

The heat index will reach the highest readings between 3 and 6 p..m., according to the hourly forecast.

High temperatures Tuesday were 90 in New Haven and Meriden, 89 in Bridgeport, 87 in Danbury, 86 in Greenwich and Norfolk and 83 in Groton.

The greater Hartford/Windsor Locks area remains the hottest spot in Connecticut with a high of 95 degrees on Tuesday. It was the fourth consecutive day that the temperature was 90 degrees or above.

The average temperature on those days was more than 9 degrees above normal for this time of year, according to the Northeast Regional Climate Center.

There is a chance of showers or thunderstorms through Thursday.

Any precipitation would be welcome because rainfall totals are more than 1 inch below normal across the state. The latest report from U.S. Drought Monitor has the northern third of Connecticut under moderate drought conditions.

Because Tropical Storm Isaias tracked farther west, Connecticut did not get much rain.

Highest rainfall totals from Isaias were in Litchfield County with 1.38 inches in Goshen, 1.23 inches in Canaan, 1.04 inches in Litchfield, 1.03 inches in New Milford and .53 of an inch in Torrington.
