PM Update: Scattered showers and much cooler temperatures on Monday
Today marked our second straight day of 90-plus-degree temperatures. Thankfully, we wont make it three in a row. A cold front and its associated upper-level disturbance will make things much more unsettled on Monday. Temperatures will be a good 15 to 20 degrees cooler than todays, with scattered showers and overcast skies the rule and not the exception.
Through tonight: Gusty winds will taper off after sunset. Clouds continue to build overnight, and temperatures will remain quite warm. Lows will hover in the upper 60s outside the city and stay right around 70 degrees downtown. A few scattered showers may develop in the predawn hours, especially north and west of D.C.
Tomorrow (Monday): A rather dreary day, with lots of clouds and showers. Rain should be with us in the morning and will persist for much of the day. Temperatures will be much cooler, with highs in the low to mid-70s and a cool east wind at 10 to 15 mph. Showers dissipate in the evening, and we are left with overcast skies and seasonable temperatures in the low 60s.
