90 Degrees + Humid = Crank the A/C

Josh Larson @ 12:30 AM

We'll look for hazy, hot, and humid conditions for the next several days. Despite the palpably muggy air, chances for widespread showers or thunderstorms remain low, so our recent rainfall deficit is unlikely to be remedied anytime soon.


Forecast Confidence: MediumSunny & hot. Today will feature abundant sunshine accompanied by noticeable humidity. We'll look for afternoon highs in the upper 80s in the cooler spots (near the bay) to the low 90s in the warmer spots (mostly to our south). Mostly clear and muggy tonight with lows from the upper 60s to low 70s.


Forecast Confidence: MediumAs hot; muggier. We'll see mostly sunny skies on Friday with uncomfortable humidity levels (as dew points approach the 70-degree mark) and highs once again near 90. There is a slight (<25%) chance of a stray afternoon or evening thundershower, but the majority of area will remain dry. Mostly clear and muggy Friday night, with lows again from the upper 60s to low 70s downtown.

Those with outdoor activities over the next few days -- like these softball players at Potomac Park captured Tuesday by photographer Ian Livingston -- should be prepared to sweat a lot!

The Weekend

Confidence: High-Very HighHot Saturday; Warm Sunday. We'll look for a continuation of hot and muggy conditions, along with mostly sunny skies, on Saturday, with highs once again near 90 and overnight lows near 70. A stray afternoon thunderstorm cannot be ruled out, though many places will remain dry. Expect a blend of clouds and sun on Sunday with more comfortable temperatures in the low 80s for highs and a continued chance of an afternoon shower or thunderstorm. Overnight lows in the mid to upper 60s.

Pattern Overview

A large ridge of high pressure centered over the eastern third of the nation over the next several days will allow for a predominately southwesterly flow pattern, which will do a very effective job of cranking up the heat (with afternoon highs some 10 degrees above average) and humidity. Unfortunately, no impressive cold fronts are in sight, so any thunderstorms that do develop Friday through the start of next week will be few and far between. That being said, after Saturday we'll see temperatures and humidity levels drop off just a little bit, making conditions next week more pleasant and less burdensome on air conditioners.


Next week's forecast
Forecast highs/lows: 83/64 (normal = 82/63)
Forecast precip: Near normal?

Forecast Confidence: High-Very HighWe'll look for similar conditions on Monday and Tuesday with partly to mostly cloudy skies and a 50/50 chance for showers and thunderstorms either day; high temperatures will hang out in the low 80s with overnight lows primarily in the low to mid 60s. More sunshine and lowered chances for precipitation are likely on Wednesday and Thursday with high temperatures from 80-85 and overnight lows from 60-65. From this far vantage point, it appears that more clouds as well as a chance for showers and thunderstorms are possible on Friday with similar temperatures to Wednesday and Thursday.
