D.C. area forecast: The sizzle of summer is on for the next 3 days

* Air quality alert: Code orange – unhealthy for sensitive groups today *

A somewhat subjective rating of the day’s weather, on a scale of 0 to 10.

2/10: Hang in there though you want to swear. Beat the heat. Spurn the burn. Show no timidity despite rising humidity. Or, do like me and turn up the A/C.


Today: Mainly sunny, increasing humidity. Highs: 92-96
Tonight: Calm and mostly clear. Lows: 68-75
Tomorrow: Partly cloudy, isolated late day t’storm possible. Highs: 91-95


The heat is on for at least the next 3 days and the humidity climbs, though it is not unbearable today. This is some serious heat with record highs well within reach, especially Friday. So head to the beach, find the water park, the pool, the slip and slide, or even the lawn sprinkler as we work on acclimating to a summer that is off to a fast start.

Our big hope for relief is a weak cool front late Saturday into Sunday, but the operative word is weak. At least the front should be capable of a few cooling thundershowers Saturday afternoon and evening.

Today (Thursday): Temperatures sprint upward today as our protective veil of smoke streams out to sea. Highs top out in the low-to-mid 90s. Humidity is on the rise as well but still moderate by my reckoning. Breezes are weak but welcome. Confidence: High

Tonight: The breeze falters making evening strolls with readings still in the 80s less desirable. Skies are mainly clear allowing a nice view of Jupiter and Venus at dusk and the crescent moon in  the early morning. Lows only fall to the upper 60s to mid-70s. Confidence: High

Tomorrow (Friday): This day gets off to a warm start and gets steadily hotter making outdoor activities a challenge by mid-morning. A light south breeze provides the only marginal help as highs top out in the low-to-mid 90s yet again. Skies, while clear, get a little hazier as humidity is starting to breach levels of discomfort. Pop up clouds by afternoon allow brief moments of welcome shade. Confidence: High

Tomorrow night: Evening readings in the 80s and little in the way of breeze cut down on the sidewalk table appeal. Skies remain mostly clear overnight with lows only falling to the low-to-mid 70s. Confidence: Medium-High


Saturday has clouds starting to pop up in the morning but they are not likely to curb the power of the sun much. Highs are still likely to reach the low-to-mid 90s for a third day running. Humidity is notably uncomfortable as moisture from the south surges north to meet the weak cold front pushing toward the area. Thunderstorms are likely to erupt along that front in the afternoon and evening across the entire area (60% chance). They should at least lead to a little cooler evening but overnight lows still hold in the low-to-mid 70s. Confidence: Medium-High

Sunday is Flag Day and hopefully those flags are showing a north breeze in progress. Even if all goes as planned, it is only likely to hold highs in the mid-to-upper 80s under sunny skies but even that is likely to feel like an improvement. Humidity is only slightly lower but that could be enough to keep most afternoon thunderstorms south of the metro area with just a 20% risk of getting wet. Overnight lows make a little better progress with most areas in the mid-to-upper 60s but still near 70 downtown. Confidence: Medium-High

Monday is likely to allow humidity to creep  back up but highs should still hold in the mid-to-upper 80s, especially if scattered thunderstorms develop in the afternoon (40% chance). Confidence: Medium
