“Streams continue to rise due to excessive runoff from previous rainfall,” writes the National Weather Service. The possibility of another half inch to inch of rain this evening could make matters worse.
The rainfall map below shows that a wide area along and just west of Interstate 95 in Northern Virginia saw 2 to 4 inches of rain overnight. Reagan National Airport, which received about 4 inches, was close to the jackpot. Dulles Airport received 2.32 inches while BWI Marshall Airport recorded comparatively less, just 0.93 inches.
The weather service received a dozen reports of flooding in the area overnight. Many streams overflowed, including parts of Rock Creek, flooding adjacent roads. Low-lying, poorly drained areas also experienced flooding, including portions of Interstate 295 which runs through the District and Interstate 395 which runs through Arlington and the District.

A somewhat subjective rating of today’s weather, on a scale of 0 to 10.
4/10: I could spend a day at the pool instead of a day at the puddle.
- Today: Rain, ending over time. Treble: low to mid 70s.
- This evening: Clearing. Bass: mid to upper 60s.
- Tomorrow: Partly to mostly sunny. Treble: low 80s.
We are avoiding the raindrops this morning and hopefully missing the significant flooding as much as possible. Chances of rain lessen with time today, leaving us dry by evening if not before. The rest of the predictions are significantly better. At least until we get to the heat on Tuesday. In the meantime, if you’re out today, be aware of the potential for high tide. Turn around, don’t drown.
Today (Saturday): Pockets of heavy rain are in progress early in the morning. Although it can be random, some areas could pick up too much in a short time, leading to flooding. Showers may continue intermittently into the afternoon, but the heaviest is likely to arrive early. Widespread rainfall totals of one to three inches seem like a decent bet, with some places ending up with more. It’s rather fresh even if it remains rather heavy. Temperatures may only reach the low to mid 70s in the afternoon as the winds turn out of the northeast. Gusts of around 25 mph are possible. Confidence: medium
This evening: A stray shower may linger. Otherwise, clearance. We should have a fairly clear trend by the morning. Winds are light from the north and northeast. Temperatures dip into the mid to above 60s for lows. Confidence: medium-high

Tomorrow Sunday): Humidity is down, and sunshine is the rule. We’ll see some clouds in the day’s peak heat, but it should stay dry. The highs are mostly in the 80s. Confidence: medium-high
Tomorrow evening: The sky is clear. The relatively low humidity allows temperatures to fall into a range of nearly 60 to 60 for lows. Confidence: medium-high
The sky remains rather sunny over Monday. With a wind blowing from the south, the humidity begins to rise, but it remains on the low to moderate side. Afternoon readings are around the mid-80s. Confidence: Medium
Temperatures are about to return to summery levels on Tuesday. The sun is dominant as temperatures rise in a range of low to mid-90s for the highs. Luckily, it may just be a pulse of a higher heat day, for now. Confidence: medium
