Warm 80s, fairly sunny, and dry. An un-muggy air mass too! As close to perfect as I can grade mid-summer!

FORECAST IN DETAIL

If I’m highlighting the best weather days over the next several, it might be today and next Tuesday. During the weekend our rain chances go up along with increasingly uncomfortable humidity levels. Once we get past today, the next several could even offer us a serious taste of summer H’s — heat, humidity, haze. Some storms as well. Am I leaving anything out? Summer lovers, enjoy! Those who like it a bit more temperate, get out today and then hold your breath for a bit!

Today (Friday): Sure, a bit warmer than yesterday, but summer doesn’t get much more splendid. Mainly sunny skies and tolerable humidity levels (dew points below the 60 degree mark) help us to enjoy 82-88 for high temperatures. Breezes remain light (around 5 mph) and turn from a morning northerly direction to more southerly during the afternoon. It’s on the cusp of too warm for the stamp, but it’s still July! Confidence: High

Tonight: Outdoor patios to remain crowded! Even after dinner perhaps. Temperatures get very comfortable after sunset as our non-muggy air mass allows the atmosphere to cool quickly into the 70s. CWG’s David Streit recommends looking “for a sliver of moon in the western sky at dusk,” since our skies should remain clear. Enjoy the stars! Low temperatures may halt near 70 downtown, but should cool further outside the Beltway, into the mid-to-upper 60s. Breezes remain light, out of the south around 5 mph. Confidence: High

Tomorrow (Saturday): Bam. Summer’s back. High temperatures in the upper 80s to low 90s most spots, perhaps a few mid-90s south of town — it will make you sweat. Also, these seemingly benign south-southwesterly breezes (now blowing 5-10 mph) have moistened our atmosphere. We’ll have higher humidity levels and that muggy feeling associated with dew points above 65. We should have slightly more sun than clouds but let’s call it variably cloudy on-the-whole. Those clamoring “I want summer,” have at it and enjoy! Note by late afternoon we have about a 30% chance of probably isolated to scattered storms, which could be strong to severe if they occur. Confidence: Medium-High

Tomorrow night: Shower and even thunderstorm chances rise after sunset to about 40%. Clouds do keep increasing and remain fairly numerous, even in dry spots. Low temperatures only manage to hover around 70 outside the Beltway, to mid-70s in the urban heat island. Southerly breezes may occasionally blow, at around 5 mph. Confidence: Medium-High

Sunday: It’s murky and muggy, with clouds and high temperatures in the low-to-mid 90s. We may have oppressive, soupy air with serious humidity (dew points in lower 70s) and haze. At least we won’t have too strong of a sun, with mostly cloudy skies persisting. Yet we do need to watch the potential for a few downpours in some of these potentially stronger storms. Rain chances escalate to at least 50%–perhaps 70% by late in the afternoon. Again, storms which form could be strong to severe. Confidence: Medium

A LOOK AHEAD

Sunday night: Periods of drenching rain may continue (50% chance) through the evening. Even as rain settles down before dawn, skies remain mostly cloudy. Overnight low temperatures remain steamy, in the low-to-mid 70s. Confidence: Medium

Our summertime haze and humidity continues on Monday, along with a 50% chance of more showers and storms. Luckily, some partial cloud cover should keep our temperatures somewhat subdued, relatively, in the mid-80s to around 90. One more dose of this could be worth it! The cold front should finally pass at some point, with delightful air ready to pounce from the other side. Confidence: Low-Medium

Tuesday’s our grand prize we win after all the rain, humidity, clouds, haze, and heat of days prior. Sunny skies should prevail, as the substantial cold front with some polar air behind it gives us splendid high temperatures in the upper 70s to mid-80s. I wish I could grade this day from here, because it might need a Daily Digit of ‘10’! Confidence: Medium
