Forecast: Hot With Acceptable Humidity, For Now

By Camden Walker

Muggy on Sunday with storm chances late in the day

WeatherCamIt will be hot but tolerable over the next few days, with gradually rising humidity. For a change, rain should stay out of the picture through most of the weekend. But this is a weekend after all. So it's no surprise storm chances try a comeback by late Sunday.

TODAY (FRIDAY)

Mostly sunny. Around 90. We'll be hot today, but nothing you're not used to by this point in the summer. High temperatures this afternoon should top out around the 90-degree mark. Skies will be clear, so watch out for those UV rays. But again the mugginess will not be bothersome at all, thanks to the drier air that moved in Wednesday night.

Skies will stay clear overnight. Temperatures will slowly fall to near 70 downtown and mid 60s in the suburbs. Perhaps lower 60s in outlying areas like Frederick or Culpeper.

Keep reading to see when storms enter back into the picture this weekend. Check out NatCast if you're headed to Nationals Park tonight.

TOMORROW (SATURDAY)

Slightly hotter. Lower 90s. July is still making itself known through hot temperatures. Afternoon highs will be above 90 in most spots with bright sunshine adding to the sizzle. Humidity will be higher but not at full force. Sunscreen and water remain important. But hopefully your stamina will not wear down as fast as it would in a muggier, more Floridian-type airmass!

Into the evening, skies slowly show a few more clouds, which should prevent temperatures from going too low. The city should bottom out in the low to mid 70s, and near 70 outside the Beltway. Areas like Luray or Winchester could dip to the middle 60s.

SUNDAY

More humid. Evening storms? Near 90. Partly cloudy skies will offer periodic breaks from the direct hot sunlight. Still, high temperatures will level off around 90 degrees. And you may notice more humidity, too. A cold front could threaten storms by eveningtime. So you may need the umbrella if you're out and about Sunday night. Stay tuned over the weekend as we try to pinpoint the timing of the front.

Mostly cloudy overnight with a 40% chance of storms popping up. Lows should be around 72-74. And it will be fairly humid.

A LOOK AHEAD

Clouds could hang tough on Monday, keeping temperatures a little lower. Expect afternoon highs in the mid 80s and a small chance (30%) of afternoon showers or thunderstorms. Humidity may be slow to exit. Confidence: Medium

On Tuesday, we can hopefully escape dry -- without thundershowers. At least that's how it appears now. Temperatures will probably reach the middle 80s, with lower humidity if a cold front can completely clear our region! Confidence: Medium

Comments

In spite of the forecasts for fair weather, this morning's rather abundant altocumulus seems to hint at a possible afternoon thundershower. Sterling also notes that NAM/RUC guidance could be hinting at potential PM convection though there seems to be a rather strong inversion "cap" at ca. the 750mb level.

Tony Pann is reporting a dewpoint of 65. It does feel a bit humid outside.

Bertha continues to drift to the SE of Bermuda, while maintaining Category 1 strength.

My garden didn't benefit from this week's "stormy" weather. All of the storminess was deflected to the north, south, east, and west of us. Bring on the rain!
