Through Tonight: Temperatures and dew point values will stay elevated over the next few hours. A line of thunderstorms will begin to approach the Washington area and surrounding suburbs sometime after 6 p.m. As Ian and Jeff mentioned in their post, the main threats from these storms will be heavy rainfall, lightning, with a chance that some of these storms contain damaging wind gusts and small hail. An isolated tornado or two cannot be ruled out, especially in our eastern areas.

We are thinking that the worst of the storms will impact areas well to the northwest of us first, before the line moves through the Washington area between 7 and 11 p.m. Everyone should keep an eye out for updates, both from the National Weather Service and right here at the CWG. This is the type of situation where we won’t know exactly where the worst of the storms will move until we actually see how the line sets up, which doesn’t leave a lot of time or room for error. Scattered showers will remain around the area through about midnight, before we are left with mostly cloudy skies overnight with temperatures in the low to mid 60s.

Tomorrow (Sunday): A frontal boundary will stall out south of the Washington-metro area, likely somewhere between Charlottesville and Fredericksburg. That frontal positioning will leave us on the northern side of the boundary, which means conditions will be quite cool and cloudy. High temperatures will likely only reach the mid to upper 60s around the District, with even cooler temperatures (upper 50s to low 60s) north and west of the city. Winds will be light out of the east/northeast at 5 to 10 mph. In addition to mostly cloudy skies, some showers are likely to develop by late morning into the early afternoon. At this point, it looks like most of the precipitation will stay well to the north of the District. But the exact positioning and intensity of these showers is highly uncertain, and will ultimately depend on where the frontal boundary stalls out. It will be mostly cloudy tomorrow night, with low temperatures about 60 degrees with a chance (40 percent) of a stray shower or two.

Dry May at DCA: With the caveat that this all may change over the next few hours, the 2018 start to May at DCA (Reagan National Airport) has been historically dry. The first 11 days of May have featured only a trace of rain at the airport, something that has occurred just six other times on record.

For the first time in 32 years, DCA has had no measurable rain through the first 11 days of May.

But it’s hard to say whether a dry start to the month of May gives any insight into how wet a summer we might have. The last time we went rainless for the first 11 days of May (1986), we ended the summer period (June-August) with 10.41 inches of rain, which is just a bit below our average of about 12 inches of rain during that time period.
