A heat advisory is posted for almost the entire state until Wednesday evening, as the National Weather Service warns it will feel hotter than 100 degrees in many places.

A persistent southwest flow of warm and humid air is providing the region with increasingly hot and humid conditions. In what will be the second heat wave this month, temperatures in eastern and central Massachusetts will be in the 90s, and it will feel like it's in the triple digits.

Acting Boston Mayor Kim Janey has also declared a heat emergency starting Monday. Cooling centers in Boston will be open from 10:30 a.m. through 6 p.m. Monday to Wednesday.

A heat wave is defined as three consecutive days or more when the temperature reaches 90 or higher. For some of us, this heat wave began Sunday. For the rest — with the exception of the absolute outer tip of Cape Ann as well as portions of Cape Cod — the heat wave will begin Monday.

Before we get to the first full week of July, many areas will have more 90-degree days than they would typically have the entire summer.

There's a minimal chance of showers and storms throughout the heat wave until Thursday, when the possibility will increase.

If you are headed to the beach, high tide will be in the middle of the afternoon — meaning less beach real estate but a shorter walk to the cooling water. Around the greater Boston area, sunsets this weekend are the latest of the year at 8:25 p.m.

While we may complain about our hot weather, it's noteworthy that the Pacific Northwest will be experiencing dangerous, all-time record heat with temperatures exceeding the century mark for multiple days.
