Forecast: Storm Chances to Return, But Not Today

By Camden Walker

WeatherCamAs hot as it will be today, you will not think it oppressive. Humidity will not accompany the heat until tomorrow and Sunday. Rain will stay out of the picture today, but storms will threaten over the weekend.

TODAY (FRIDAY)

Mostly sunny. Around 90. Light winds from the south will feel pleasant -- not yet ushering in any palpable humidity. Skies will be clear and haze minimal, yet do prepare for highs around the hot 90-degree mark (about average). Don't forget your sunscreen today. UV will be "very high" with few clouds to shade the sun.

Skies will stay mostly clear overnight. Temperatures will fall to the upper 60s downtown and mid 60s in the suburbs. A fairly pleasant, dry, mild evening for any outdoor plans you might have! Dining al fresco, anyone? Light southerly breezes will feel oh-so-good.

Keep reading to see when storm chances sneak back into the picture this weekend.

TOMORROW (SATURDAY)

Partly sunny. More humid. Storms? Near 90. Temperatures will get up to near 90 again, and humidity will be a bit higher but not horrible. The heat may not be as fierce as last weekend, but still drink plenty of fluids if going outside for a long period of time. The chance of a rumbling thundershower cooling things off in the afternoon or evening is about 30-40%. Light winds from the south will bring increasingly moist air, breezing at about 5-10 mph.

A 30-40% chance of a shower or thunderstorm continues into the evening. Overnight lows will remain fairly high in the city, 71-75 degrees, with areas outside the Beltway dropping down to 67-70.

SUNDAY

Humid, mostly cloudy, PM storms? Upper 80s. Skies will be murky for most of the day. Temperatures should make the upper 80s, but reaching 90 will depend on whether enough sun breaks through mostly cloudy skies. Regardless, typical July humidity will provide that midsummer feel, and could trigger (30-40%chance) some showers and storms toward the end of the day.

Partly to mostly cloudy overnight with storm chances about 30-40%. Lows should be in the upper 60s to low 70s. And it will be fairly humid.

A LOOK AHEAD

Another lucky "break" on Monday is possible with partly sunny skies and decreasing humidity. Yet high temperatures will still be around 90 degrees, and a late-day storm chance remains in the forecast. Confidence: Medium

On Tuesday, humidity could bounce back up again. As of now, shower/storm chances stay in the picture, albeit only around 30%. Highs in the upper 80s to near 90. Confidence: Low-Medium
