8:30 p.m. update: Scattered storms continue, mainly east of I-95 from southeast Fairfax county (near Mt. Vernon) through parts of northern Prince George’s county and into Anne Arundel county. An isolated storm has formed west of Great Falls in northern Fairfax county and extends towards North Potomac in Montgomery county. Most of this activity should diminish in the next hour or two as it heads northeast. Drier air and at least partially clearing skies should move in after 11 p.m. in places seeing storms now.
6:25 p.m. update:Showers and thunderstorms tracking north through eastern Prince George’s County, along the west side of the Bay and in Southern Maryland should move away to the east over the next couple hours.

Today (Saturday): We start the morning with mostly cloudy skies and about a 50% chance of lingering rain, and those odds diminishes going through the day, to a slight (20% chance) by afternoon. Places east will hold the risk for showers longest. Some clearing is likely, though the front won’t get too far south, and we may still hold a fair number of clouds through the day. Highs should mainly settle in the mid-80s, but there’s a chance someone gets a bit higher. Confidence: Medium
Tonight: A slight chance of showers lingers into the night, but most spots stay dry. Partly cloudy to mostly cloudy skies may slightly hamper Perseid meteors, yet I think we’ll have plenty of breaks to not ruin hopes (stay away from the light -- of the city). Lows range from the low-to-mid 60s in the outer suburbs to close to 70 downtown. Confidence: Medium

Tomorrow (Sunday): This looks like a pretty superb summer day overall. It’s not cool, but it’s not oppressive in the least. Mostly sunny skies and humidity nearing “low” ranges? Fingers crossed. Highs reach the mid-to-upper 80s -- a pretty “average” mid-August day. Confidence: Medium-High
Tomorrow night: Our low humidity and cooler air mass appear to overlap the most on this mostly clear Sunday night. Some folks may near 60 for a low while downtown even probably makes the upper 60s. Refreshing?! Confidence: Medium-High
On Monday, mostly sunny skies are the story again. I don’t anticipate any storms around, but if I assigned a percentage chance it’d be around 10%. You never know, right? Highs reach the upper 80s to near 90. After sunset, increasing humidity and increasing clouds help keep temperatures from dipping much below the upper 60s to low 70s. Confidence: Medium-High
Tuesday is partly cloudy, toasty and muggy. We’re getting deeper into the month, but it’s still August after all. Highs may end up pretty similar to Monday, though I think a smidge warmer, so let’s say near 90 to low 90s. The chance for a late-day shower or storm is up, to about 30%. Confidence: Medium
