Humidity ramps up a bit today but heads back down a bit tomorrow. Sunday and into next week shows signs of real warmth and humidity building over us. Let’s try to spin-positive the high temperatures in the 80s while we have them, I suppose. Or get to a pool or beach by the end of the weekend! Just remember the saying “if thunder roars, head indoors” so as to stay safe during outdoor activities near pop-up showers and storms while you’re out this weekend.

Today (Friday): Broken and scattered clouds throughout the day shouldn’t prevent the sun from warming us into the mid-to-upper 80s. Dew points are on a creep upwards too, so be mindful and drink that water. Light northeasterly breezes 5-10 mph turn a bit more east-southeastward, and presumably contribute to our increased water vapor in the air. For those headed off to the beaches, it looks like a good time for it. I am jealous if you can cool off at the shore, where it might be almost as muggy, but a bit cooler next to the ocean. For folks staying around D.C., there’s a very off chance (~10%) we cool off with a thundershower. Confidence: Medium-High

Tonight: Enjoy D.C.’s latest (8:38 p.m.) sunset of the year, despite some cloud cover. Maybe sunset colors will be enhanced? I am just a bit worried we have a few moments of overcast skies. Periods of clouds want to move in and out of the region overnight. East-southeasterly breezes between 5-10 mph increase our chances of a muggy and somewhat cloudy overnight. We even have a 15-20% chance of a rogue shower or two wetting us briefly. Low temperatures may only drop into the mid-60s to around 70 (downtown). Confidence: Medium-High

nice dayTomorrow (Saturday): It’s still warm, but should deserve to be labeled a Nice Day due to decent chances that our humidity decreases throughout. Even if we have early clouds, sunshine should increase as the day wears on. High temperatures in 82-87 degree range appear likely. With it being summertime in D.C., I still think it prudent to assess a 10% chance of a stray shower or thunderstorm–especially south and southwest of D.C. where it may remain a bit juicer and warmer. Variable breezes at 5-10 mph refresh us from time to time. Confidence: Medium

Tomorrow night: We could be fighting to see the stars at times through some of our lingering clouds. Overnight low temperatures do not drop too much, thanks to periodic southeasterly breezes continuing around 5 mph and aforementioned clouds. Mid-to-upper 60s is about as cool as we can get just prior to sunrise. Confidence: Medium

Sunday: This one should be summery but not terrible. Slightly more heat and humidity is accompanied by a 25-35% chance of showers and storms, especially by late afternoon. The highest chances are perhaps to the south and southwest of D.C. Light northeast breezes may occasionally blow, but they shouldn’t hinder temperatures from reaching highs in the mid-to-upper 80s. Confidence: Medium

A LOOK AHEAD

Sunday night: After the sun sets, we should see any lingering showers and storms (20-30% chance) dying out before 11 p.m. or so. Skies may remain mostly cloudy though. Upper 60s to around 70 downtown is about as “cool” as low temperatures get before dawn. Confidence: Medium

By Monday we may skip a day ahead in the calendar to feel a bit more like July. Mostly sunny skies plus that mid-summer humidity create heat indices well into the 90s, even if temperatures top out in the upper 80s to around 90. We may see a few towering clouds build in the afternoon, if thunderstorms (20-30%) get going. Confidence: Medium

Tuesday’s likely to be really muggy and hot. High temperatures have a chance of puncturing the 90 degree mark early and easily, with afternoon readings in the low-to-mid 90s. Let’s hope the 25-35% chance of showers and storms do end up cooling us off a bit, late in the day. Confidence: Low-Medium
