FORECAST IN DETAIL
Summer arrives today in just the fashion you might expect. It’s hot, and humidity starts rising tonight. With a 90-degree reading on Sunday, D.C. even has a shot to manage the first heat wave of the season if we can keep the streak going into tomorrow. After that, it seems we may have enough cloudiness — plus off-and-on storminess — to keep temperatures from really soaring. But hotter stuff won’t be far off, so we’ll need to keep an eye out.
Today (Monday): Skies are sunny as we head back to work but, at least, the humidity shouldn’t be too bad. Some puffy clouds probably form during peak heating in the midday and afternoon, although none are expected to deliver any rain. Highs head mainly to 90 degrees and above. Confidence: High
Tonight: The great thing about summer in the area is the evenings tend to be fantastic. This one should fit the bill as temperatures fall back into the 70s by sunset. Clouds increase with time as some storms to the northwest head this way. By the time they get here, probably between midnight and dawn if they do, it’ll likely be just some scattered showers with perhaps rumbles mixed in. Lows are in the upper 60s and lower 70s. Confidence: High
Tomorrow (Tuesday): Any overnight showers are out of here pretty quickly in the morning. Skies trend partly cloudy afterwards. A front is headed this way and a strong jet stream is overhead. If sunshine destabilizes the atmosphere enough, a round of strong-to-severe storms is likely during the afternoon into the evening. The main threats in any storm, in addition to lightning and heavy rain, would likely be strong winds. Afternoon temperatures head to around 90. Confidence: Medium-High
Tomorrow night: Showers and storms wind down during the evening if not prior. After that, it’s a pretty calm night. Skies are partly to mostly clear as temperatures reach the mid-60s to near 70 for lows. Confidence: Medium-High
A LOOK AHEAD
For Wednesday, a frontal zone pushes off to our south but doesn’t get all that far. It should be enough for skies to end up partly to mostly sunny, but we may see the front begin to return north by late in the day or evening with more in the way of cloudiness. High temperatures are in the pleasant low- to mid-80s. Confidence: Medium
On the periphery of a ridge of high pressure over the western United States, the jet stream will want to keep sending little waves toward our area. The next comes along on Thursday. Additionally, the old front is drifting back north as the next wave approaches. That means another round of showers and storms is possible. Depending on the timing, these storms could again be strong or severe. High temperatures head for the low- to mid-80s. Confidence: Medium
Showers may linger into Friday as that frontal zone again drops to the south and begins to wash out. Highs are mostly near 80, as more sun tries to peek through with time. And that sun becomes prevalent as the weekend starts, with both days seeming to be partly to mostly sunny and featuring highs in the mid-80s. Right now, our next storm chance looks to be about Monday, but we’ll let you know if that changes! Confidence: Medium
