It鈥檚 officially summer and the D.C. region’s first heat wave is forecast to start on Sunday, just days after damaging storms toppled trees onto homes and cars in the area.
Temperatures are expected to reach 100 degrees next week, but the humidity will make it feel even hotter.
鈥淲e’re going to get progressively hotter Sunday, Monday, Tuesday, Wednesday, even into Thursday of next week,鈥� said 791欧美激情 First Alert Meteorologist Steve Rudin.
A heat wave is defined by the National Weather Service as a period of abnormally hot and humid weather that lasts more than two days.
The peak of the heat wave will come Monday and Tuesday, with heat index values as high as 105 to 110 degrees. Dew point levels, or the measure of moisture in the air, are going to be well into the 70s.
鈥淭hat鈥檚 when it feels really swampy and sticky and really uncomfortable,鈥� Rudin said. 鈥淏ecause it’s so humid and so sticky, you’re going to sweat almost instantly once you get outside.鈥�
Making matters worse, residents across the D.C. region aren’t expected to even get much relief from the humidity by the time the sun goes down.
鈥淚t’s still going to be incredibly uncomfortable,鈥� Rudin said. 鈥淚t’s not going to be very windy. The air is going to be fairly stagnant, and we’ll also be looking at some hazy conditions.鈥�
A dry pattern sets up for the next several days, but with increasing heat starting this weekend. Well above normal temperatures are looking likely from Sunday through Wednesday. Afternoon heat indices approach 100-110 degrees at times during this period.

It鈥檚 likely parts of the D.C. region will see heat advisories and excessive heat alerts.
Some safety measures to keep in mind include minimizing direct sun exposure, reducing strenuous activities, wearing light clothing and drinking plenty of water, .
