A very hot and humid air mass will move over the region for the next few days, but some relief is in sight for the weekend.

This Afternoon: Mostly Sunny, Hot & Humid

Highs: Upper 90s | Wind: SW 5-10 m.p.h.

Overnight: Mostly Clear & Muggy

Lows: 70s | Wind: SW 5 m.p.h.

Thursday: Mostly Sunny, Hot & Humid, Iso. T-Storm

Highs: Upper 90s | Wind: SW 4-8 m.p.h.

A record high has been reached at BWI Thurgood Marshall of 98 degrees (so far) and has been tied at Reagan National where it also sits at 98.

A Heat Advisory is in effect from Noon until 8pm tonight as heat index values may reach 105 degrees. Highs should reach the upper 90s today with dewpoints in the 60s, making it feel more humid. Tonight, skies will be clear and temperatures still warm in the 70s. The high heat and humidity will last through the day tomorrow with highs in the upper 90s once again under mostly sunny skies. A few storms are possible tomorrow afternoon, but that will mainly be in the mountains. A few record high temperatures may be broken as well today and tomorrow.

A cold front will move into the region Thursday night into Friday and stall overhead through the weekend. This will bring the chance for showers and thunderstorms along with temperatures that won't be quite as hot. Highs Friday should still reach the lower 90s. The weekend will be much improved in that category though as they should reach the mid 80s each day. Showers and thunderstorms appear like a possibility Friday through Sunday under otherwise partly sunny skies.
