Mother Nature is really going to crank up the heat Wednesday, and she plans on doing the same through the weekend.
High temperatures are expected to climb into the mid 90s today and top out in the upper 90s to close to 100 degrees Saturday and Sunday, the National Weather Service said in its morning briefing.
Couple those numbers with extremely humid air and it's going to feel more like 105 to 110 degrees, prompting the weather service to issue a high heat advisory for the region for today.
Portsmouth will open cooling stations around the city: the main library from 10 a.m. to 6 p.m., Churchland library from 10 a.m. to 8 p.m., Cradock library from 10 a.m. to 5:30 p.m., Manor library from 10 a.m. to 6 p.m., Human Services from 8 a.m. to 5 p.m., City Hall from 8 a.m. to 5 p.m., Senior Station from 9 a.m. to 4 p.m. and Behavioral Heathcare Services from 8 a.m. to 8 p.m. Water will be provided and only service animals will be permitted in the facilities.
In its briefing, the service said an advisory will likely be issued again on Thursday, followed by excessive heat warnings for the weekend.
Temperatures will be slightly cooler along the immediate coast.
Afternoon cooling from thunderstorms like the ones that popped up Tuesday afternoon aren't likely Wednesday. There will be an increased chance of rain Thursday afternoon, the weather service said.
The region won't get a break from the hottest week of the year so far until Monday night or Tuesday, the weather service said.
