To start this week, we’ll add another day or two to the streak before a midweek reprieve. But then there is the potential for the hottest weather of the summer late this weekend, when triple-digit highs are a possibility. Storm chances will be limited this week; today may present the best opportunity, and it’s a marginal one. Today (Monday): It’s a steamy one. Under a mix of sun and clouds, highs head for the mid-90s, but humidity is up noticeably compared with the weekend. The combination of heat and humidity makes it feel close to 100 at times this afternoon. There’s a 20-30 percent chance of storms developing late, highest in our western areas. Confidence: Medium-High Tonight: A few evening storms are possible, but they should be hit or miss — with the most action west and northwest of the District. Otherwise, it’s partly cloudy and muggy, with overnight lows ranging from near 70 in our cooler suburbs to the mid-to-upper 70s downtown. Confidence: Medium-High |
