* Update, 6:30 p.m.: So far, storm coverage has been less than expected. Storms look to be mainly isolated (well north of D.C.) through 8 p.m., and may increase some after that time. Follow our Twitter feed below for additional updates. If there’s any major change to the forecast, we’ll post an update here.

Original: For the first time in 11 days, temperatures have failed to reach 90. But, we’ve still warmed up enough to fuel a round of likely evening storms, a few of which may be severe. The trigger, a slow-moving front, takes a chunk of Saturday to pass through the area, meaning residual clouds and possible showers through the morning. We finally clear out Saturday night and Sunday.

Through Tonight: Showers and thunderstorms are likely to develop starting around 6 p.m. in the southwest suburbs. Between that time and around 10 p.m. is the most likely window for any severe weather (early in the window west, later in the window east). Damaging wind gusts and hail are possible in a few storms and, as we’ve said, an isolated small tornado can’t be entirely ruled out somewhere. Mostly though, expect heavy downpours and lightning.

Showers and storms remain possible through the night, but decrease in coverage and intensity between 10 p.m. and midnight. Overnight lows range from the upper 60s in the cooler suburbs to the low 70s downtown.

Saturday: Clouds and showers (20-40 percent chance, west-east) are possible, especially along and east of I-95 in the morning. By 2 p.m., most of the area should be drying out with some emerging sun, unless you’re at the Maryland/Delaware beaches, where clearing may hold off until evening. Highs are in the low-to-mid 80s.

Saturday night: Partly to mostly cloudy skies early likely transition to mostly clear skies late at night. That should allow for good Perseid meteor shower viewing at the optimal times post midnight. Overnight lows are pleasant, ranging from the low 60s in the cooler suburbs to near 70 downtown.

Sunday: Mostly sunny and very pleasant with beautiful sunshine and low humidity. Highs in the mid-80s.
