TODAY’S DAILY DIGIT
A somewhat subjective rating of the day’s weather, on a scale of 0 to 10.
1/10: Breezes, though from a warm direction, merit a point for attempted cooling. Otherwise, hazy and muggy 90s.
Today: Hazy sunshine. Isolated p.m. shower/storm? Highs: 90-95.
Tonight: Turning mostly clear, muggy. Lows: 70-78.
Tomorrow: Partly cloudy. PM shower or storm risk. Highs: 90-95.
Sunday: More clouds than sun? Highs: 87-92.
FORECAST IN DETAIL
It may feel like 100 or hotter today and tomorrow, when taking the temperature and adding in the humidity (AKA, the heat index). Our heat would be impressive in July—during which, our highest average high temperature of 89 occurs. Could we see “only” 80s on Sunday? Possibly our only break from serious heat. How long that lasts is up for debate, as the heat could just come roaring back thereafter.
Today (Friday): Air quality still isn’t great, on top of muggy dew points in the upper 60s to around 70 making it difficult for our sweat to evaporate. Periodic clouds, haze, and moments of smoke, could filter our mainly sunny skies. Get outdoor activities done early, before temperatures climb to a near 90 to mid-90s range during the afternoon. Thank goodness for a sometimes helpful 5-10 mph cooling breeze out of the south. Isolated showers/storms may fire after noon but with only about a 20% chance. Confidence: High
Tonight: We have about a 20% chance, still, of an isolated shower or storm during the evening. Temperatures only slowly fall. 80s after sunset should settle before dawn into the low 70s outside of the Beltway, with a few upper 70s possible inside the Beltway. South and southwesterly breezes may die down a bit and really put a cap on us—stagnating the late evening air with humidity. Skies should remain mostly clear overnight, albeit just a bit of haze tagging along. Confidence: Medium-High

Tomorrow (Saturday): Periodic clouds shouldn’t be able to completely block the sun, until perhaps after dinner. Cloud prediction remains very uncertain with such a thin layer of atmospheric molecules interacting to produce clouds or not. Hard to say with confidence when and how much in the way of clouds may occur—especially from here. Even with periodic clouds, high temperatures should still reach near 90 to the mid-90s for a third day running. With moist dew points around 70, humidity is notably uncomfortable. A few showers or storms (30% chance) may pop. West winds near 10 mph could shift to the northwest, if we are fortunate to have a weak cold front clear the region. Confidence: Medium
Tomorrow night: Thunderstorms could still roam (40% chance), with some accompanying showers, during evening hours. Perhaps carry around a small umbrella if you’re out roaming as well. Clouds remain fairly thick, even when rain isn’t falling. We should cool down just a bit overnight—still with some mugginess—in the upper 60s to low 70s. Hey, we’ll take what we can get, right? Though I am sure air conditioning units may still be heard buzzing for most, if not all, of the night. Confidence: Medium
Sunday: Light but steady northerly breezes are possible to help move our flags on Flag Day. Even if the aforementioned weak cold front clears our region and we get the as-planned breezes, we still remain summery. Just with less sizzle. High temperatures in the upper 80s to low 90s are possible, along with humidity. Somewhat moderated humidity. Skies may or may not want to clear. We’ll have to watch just how far our front can move away from us, and thus allow skies to clear more. Watch radar with us later in the afternoon to make sure thunderstorms stay south of the metro area (as currently expected) but we’ve a 10-15% risk of getting wet. Confidence: Medium
A LOOK AHEAD
Sunday night: With a southerly flow trying to reassert a more summer-like pattern over our region, the sneaky showers from the south have a slightly better chance of invading the region overnight (20% chance). Even without dampness, clouds appear to hang tough, with somewhat overcast periods probable. Mugginess may ride northward with the showers and southerly breezes, keeping our low temperatures fairly warm, in the low-to-mid 70s. Confidence: Low-Medium
We’re seemingly settling into classic summer conditions at the least to start the week, and maybe turning hotter again depending on how things go. As of now, both Monday and Tuesday appear to have relatively similar weather. Both days are seasonably toasty as highs rise to the upper 80s to low 90s. Sunshine is increasingly blotted by clouds each afternoon, as a risk of scattered showers and storms presents itself during the heat of the day. Confidence: Low
