Any storms that do develop could be strong/severe with locally heavy rain.
Thursday afternoon will feature some sunshine to dry the area out but a few pop-up storms aren't completely ruled out either as it begins to head into a warming trend heading this weekend. Officially, a heat wave is three or more days in a row of 90-degree high temperatures, and we should have no trouble qualifying over the next seven days.
Overnight low temperatures are expected to dip only into the upper 70s, which does not allow buildings (and their occupants) much of a chance to cool off.
Excessive Heat Watch means the heat index will reach 100-105 degrees.
Forecasters there say this dangerously hot weather won't let up until the middle of next week. The heat index should approach 100 on Friday afternoon and could get as high at 110 on Saturday afternoon. The worst of the heat is likely to peak on Sunday afternoon. The reported temperature at Logan Airport as of 1 p.m. Sunday was 91 degrees and the heat index was 98, the weather service said.
The risky heat that is on the way raises some issues that everyone should be aware of.
The heat will stick around during the first week of July.
Drink plenty of water, stay in the air-conditioning and out of the sun. To reduce risk during outdoor work, the occupational safety and health administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Officials also encourage people to ensure pets have enough food and water.
Wear lightweight, light-colored clothing.
A true signature of a heat wave is the little relief provided at night.
THURSDAY | Variable clouds with PM t'storms possible. "It'll still be hot and humid in the mid-90s".
Despite the hot and humid weather we have stayed below record levels set during a very hot streak in 1931.
Sunday night - Partly cloudy, with a low around 74.
TONIGHT - Clear Skies and Warm.
Another round of severe weather will fire up Saturday across parts of the Midwest with damaging winds, large hail and brief tornadoes possible from Kansas to Michigan's Upper Peninsula.
