It wasn’t hard to love the weather today. High pressure, warm temps and low humidity made for a near-perfect Sunday. I hope most of you get a chance to spend some of it outside, because the return to normalcy (heat, humidity and storms) is just around the corner.

Through tonight: Lovely weather conditions on this Sunday evening, with low humidity and temperatures in the 70s through sunset. Mostly clear and comfortable to start the overnight period, with temperatures ranging from 65 to 70 degrees. Humidity values will start to rise after midnight, and some clouds/low fog may build as winds switch to the southeast.

Tomorrow (Monday):  Partly cloudy to start with some scattered showers (20 percent) possible in the morning, mainly toward the east of Washington. Otherwise, mostly sunny and warm with increased humidity. High temperatures ranging from 87 to 91 degrees with dew points in the mid-60s. Another chance (15 percent) of some scattered early afternoon showers. Winds will be from the south-southeast at 5-10 mph.

Unusually dry air: Not like I am complaining. But this morning’s sounding from Washington Dulles International Airport showed a precipitable water value (measure of the amount of moisture in the air) of 0.74 inches. That is rather low for July in the D.C. area. In fact, 90 percent of the time (as shown in the graph below), we have more moisture in the air on July 9 than was recorded this morning. If only it could last!
