The heat is on -- again.
Another excessive heat watch is being issued for Thursday when air temperatures are expected to flirt with the 100-degree mark by the afternoon in parts of Ramsey and Hennepin counties, according to a National Weather Service.
"It will start feeling really hot in the metro and most of Minnesota on Wednesday," said National Weather Service forecaster Lisa Schmit. "Temperatures should be in the low to mid-90s that day."
And by Thursday, temperatures could hit 99 to 100 degrees, she said.
But for those looking for the bright side, dew points will range from 55 to 60 degrees, making it feel less sticky than some of the steamiest days this past summer -- a drier heat than of those earlier heat waves, Schmit said.
As of Monday, this summer has tallied up 26 days with temperatures of 90 degrees or greater, 10 more than normal, Schmit said.
Thursday's warning means that the temperatures could be dangerous for people who spend time outside or in places without air conditioning. Heat illnesses are possible and people should drink plenty of fluids, stay out of the sun and in air-conditioning if possible.
The warning also advises people to check on vulnerable relatives and neighbors.
