As of 4:24pm, #DCA hit 100º F, 1 degree shy of the record for the date (101º F set in 1988). This is the first time it’s hit 100º F in June since 2012. #DCwx #VAwx #heat

This ends the fifth longest streak on record without 100 degrees for the city. Note that when looking at 100-degree readings solely for the month of June, one has to look back to 2012!
High temperatures across the region are nearing and beating record high temperatures for Saturday’s date. Dulles Airport hit at least 99 degrees, tying its 1988 record. Baltimore Washington International Airport recorded at least 101 degrees, breaking its 1988 record of 100. And National Airport posted at least 98 degrees, still below its 101-degree record.
Stay as cool and hydrated as possible through Sunday, as our heat wave approaches dangerous levels at times.

Through Tonight: If any storm or two pops up, they should die off quickly by mid-evening. Otherwise it’s partly cloudy and fairly swampy with heat index values staying in the 90s much of the night. The thermometer may only dip into the mid-70s to low 80s. This may tie or beat record-warm low temperatures for the date. We’ll keep you posted.

Tomorrow (Sunday): Similar to Saturday, and starting from dangerously warm low temperatures, we may get to the mid-90s to around 100 degrees. Morning sun could turn to afternoon cloudiness, perhaps preventing a record high temperature. Combine this with the high humidity, and it may feel like 105 to 110 degrees at times. Midafternoon and later, we have chances for a few showers and storms.
A couple of strong to severe storms are possible (see below) from afternoon into perhaps the late evening hours. Breezes from the southwest may occasionally gust near 20 mph, but we doubt their moisture-laden air will feel all that refreshing. Showers and storms should wane a bit in intensity but may continue into the early morning hours as the cold front moves through slowly. Soupy 70s are as cool as we’ll get.
Slight chance for strong storms Sunday
A cold front arriving Sunday night won’t exactly deliver colder air, but it may bring a few strong to severe storms ahead of lower heat and humidity early in the workweek.
- Timing: Midafternoon into late evening
- Threats: Damaging wind gusts over 57 mph
- Possible but much less likely: Large hail; frequent lightning; brief downpours; a weak tornado well north/northeast of town
To put this into perspective, experiencing an impact from a severe storm on Sunday is less likely than experiencing an impact (let alone discomfort) from the dangerously high heat index values.
