Washington D.C. residents are looking at a weather pattern that can only be described as classic summer mixed bag: alternating sun, clouds, and a good chance of showers and thunderstorms pulsing through the region over the next several days. The National Weather Service (NWS) forecasts "a chance of showers and thunderstorms, mainly after 2pm," with today's high ticking up near the 90-degree mark. Humidity is already gripping the air, leaving it nearly wringing wet at 94%.

Those in the DMV area should be on the lookout for possible flash floods this afternoon, a consistent threat with this type of muggy weather. The NWS cautions that "Scattered instances of flash flooding are possible this afternoon," but there's no need to battening down any hatches beyond today; the outlook for the rest of the week appears to be hazard-free. That said, stubborn commuters might want to keep an umbrella at hand or be prepared to wriggle into a rain poncho on the fly, as showers are likely over the next several days.

Tonight, there's "a chance of showers and thunderstorms, mainly before 9pm" with a low dropping around the mid-70s, which sounds like a sticky night ahead. Looking past to Wednesday and Thursday, the thermostat pushes further, with highs stepping up into the low 90s. The heat index on Wednesday could soar as high as 102, which is a gentle reminder that the dog days of summer are, indeed, dogged.

By the time the weekend rolls around, we're still to play the same will it / won't it game with the weather as there's "a chance of showers and thunderstorms after 2pm" with highs in the upper 80s. The rain is likely to follow us into the start of next week, as the NWS predicts that "Showers likely and possibly a thunderstorm" will color the day. Amidst the relative uncertainty, there's a silver lining in the mostly sunny prediction for Monday, even if it does come with a 40% chance of precipitation.
