FORECAST IN DETAIL

After three straight days of record heat, we moderate a bit today, but it’s still pretty hot. The combination of highs in the 90s and elevated humidity levels will push the heat index to between 100 and 105. A front tries to bring temporary cooling in the form of scattered afternoon, evening and overnight showers and storms. This feature will then retreat back to the north tomorrow, which means the high heat and humidity stick around with a lingering chance of showers and storms through the evening. The front finally clears the region after midweek, allowing us to cool off to more typical mid-August temperatures late in the workweek and into the weekend.


Today (Monday): It’s another scorching hot day as temperatures quickly rise into the 80s and ascend into the low to mid-90s by lunchtime. A mostly sunny sky aids the heat buildup, though puffy cumulus clouds will begin to develop as morning transitions to afternoon. High humidity levels (dew points in the low 70s) will not only make it feel like 100 to 105 during the afternoon but also help fuel the development of late-afternoon storms. While scattered across the area, these storms could produce flash flooding and briefly strong wind gusts. Otherwise, winds are light and switch from out of the north during the morning to out of the south in the afternoon. Confidence: Medium-High

Tonight: Showers and storms linger this evening, with some continuing to be heavy rainers. Their strength and coverage begins to wane after sunset. It’s partly to mostly cloud otherwise, with lows remaining warm in the mid-to-upper 70s (suburbs to city). Winds are light out of the south. Confidence: Medium-High

Tomorrow (Tuesday): The early-morning should feature a few showers in spots, but partly to mostly sunny skies are prevalent for the day. Temperatures again rise quickly through the 80s during the morning and, by mid-afternoon, peak in the mid-to-upper 90s. The sticky air raises our heat index to about 105. The entire area has a shower and storm chance during the afternoon and evening, though the most widespread coverage may be to the north of the District. Winds are out of the south at 5 to 10 mph. Confidence: Medium-High

Tomorrow night: The shower and storm chance lessens greatly after sunset, as does the threat of associated heavy downpours. We’ll be partly to mostly cloudy overnight with lows remaining warm in the mid-to-upper 70s. Winds are southwesterly at 5 to 10 mph. Confidence: Medium-High

A LOOK AHEAD

The front sags back to the south and over us on Wednesday, causing temperatures to cool a bit. Highs reach the low-to-mid 90s with dew points a little less uncomfortable in the upper 60s to near 70. With the front nearby, scattered showers and storms should fire off in the late afternoon and evening. Confidence: Medium

The cooling trend continues Thursday as the front remains draped across the region. Temperatures peak in the upper 80s to low 90s with similar humidity levels. Showers and storms are still in play, but depending on frontal position, may focus more on our southern suburbs. Confidence: Low-Medium

Friday and the weekend should be seasonably warm — upper 80s to near 90 — and feature high, yet relatively tolerable, humidity. (Dew points in the upper 60s to near 70.) Storm chances may increase Sunday in advance of a front, so you’ll want to stay tuned for updates as the week wears on. Confidence: Low-Medium
