Comment A somewhat subjective rating of the day’s weather, on a scale of 0 to 10. 4/10: Slight improvements on Friday include lower heat index values and temperatures, along with slightly less chance of showers and thunderstorms. However, one or two flooding rains are possible.
Today: A chance of showers/thunderstorms, especially in the afternoon. Highs: Upper 80s to low 90s. Tonight: A chance of light rain/thunderstorms. Sultry. Lows: mid to upper 70s. Tomorrow: A chance of light rain/thunderstorms. Highs: Near 90s to mid 90s.
With a rinse-and-repeat we’re used to during the dogs of summer, DC has virtually non-stop noise ahead and virtually daily chances for showers and thunderstorms — especially during the afternoon and evening hours. Please move quickly to safety when you hear thunder. Monday may still be the day with the least chance of rain, in case you can focus on outdoor activities then. Today (Saturday): With dew points in the mid-70s possible, heat index values in the mid-90s are possible in the hottest and steamiest spots. The thermometer can top out in the high 80s to the low 90s. Skies are partly to mostly cloudy, but we may end up seeing a bit more sunshine starting Friday. A few drops of rain are possible most of the day, but the main (and only moderate) chance for showers and thunderstorms starts around noon. Storms should be fewer than Friday, but a storm or two could still be strong to severe. We have a slight 5 to 10 percent chance of a flash flood or two. A moderate afternoon south breeze around 10-15 mph is possible. Confidence: Medium-High Tonight: An afternoon chance for showers and thunderstorms may extend closer to midnight, but any rain activity should diminish in intensity and coverage before then. Skies are likely to remain mostly cloudy, even after any rain ends. The mid to upper 70s is the best we can do for cool temperatures. Ugh. Thanks to dew points in the mid-70s that keep the atmosphere from cooling much below that level. Confidence: Medium-High Follow us on YouTube, Facebook, Twitter and Instagram for the latest updates. Read on for next week’s predictions… Tomorrow (Sunday): Skies may offer a hair more sunshine than Saturday and corresponding (hairs lower) shower and storm chances. With more sunshine, highs rise a bit more near 90 into the mid-90s. As the afternoon wears on, though, remember to head indoors if they get rowdy. A few thunderstorms are possible across the region, especially after noon. Moderate south-southwesterly breezes may be felt in the afternoon hours. Do I even need to mention how wet it will feel? Well, heat index values around 100 degrees are possible – that’s the combination of humidity and air temperature. Confidence: Medium-High Tomorrow night: After sunset, the chances of rain drop, but it’s not completely out. A slight chance of showers or thunderstorms exists until the early hours of the morning. The sky slowly clears and every breeze calm as we approach dawn. Windy lows range from the mid to upper 70s. Confidence: Average The steam can continue Monday and Tuesday, with high temperatures in the low to mid 90s. Dew points may not slide as much, or at all, as once thought. This means heat index values in the low 100s are possible. Rain chances remain lowest Monday versus Tuesday. However, a chance of rain and thunderstorms cannot be ruled out any day – especially during the afternoon and evening hours. Low temperatures are just falling into the usual range lately, in the mid to upper 70s. Confidence: Moderate Read more about Capital Weather Gang’s trust rating.
