Are you ready to say goodbye to July? Even though August is the second-hottest month of the year, our normal temperatures are starting their ever-so-gradual stepping down toward autumn now. At least for the next few days, we are treated to some less hot conditions along with a storm risk. The next surge of heat from the mid-continent “Dome of Drought" arrives Friday and especially this weekend. This results in reduced thunderstorm risks, but temperatures in the low-to-mid 90s. At least for now, I don’t see any 100-degree repeats as we tread carefully into early August.

Today (Tuesday): Partly to mostly cloudy skies prevail today along with a 30% chance of scattered mainly afternoon showers and storms (odds are closer to 40% towards the mountains and to our south) as a disturbance passes by the area. Highs are in the mid-to-maybe upper 80s in spots. Dew points in the low-to-mid 60s keeping humidity moderate overall. Winds are light and mainly from the east. Confidence: Medium

Tonight: Partly to mostly cloudy skies continue along with a 30% chance of scattered showers and storms. Those odds are again a bit higher (40%) south of the city. Look for lows to range from the mid-60s in the suburbs to the low 70s right in the city. Winds again are light and from the east. Confidence: Medium

Tomorrow (Wednesday): Another disturbance swings by the area and this one looks a bit juicier. Shower and storm chances increase to 60% for the immediate DC-area to points north/west, but increase to 70% south and east of the city (the preferred track of the disturbance). Partly to mostly cloudy skies hold temperatures in the mid-80s again. Unfortunately, winds shift to come from the south, meaning more humidity today- look for moderate-to-high levels. Confidence: Medium

Tomorrow night: Partly cloudy with a bit more humidity around as lows dip into the mid-upper 60s outside the Beltway to the low 70s in the city. Confidence: Medium


Thursday should see more sun, but still just partly sunny skies overall as highs climb up into the upper 80s to near 90. A 30% chance of mainly afternoon or evening thunderstorms is included. Partly cloudy Thursday night with lows in the upper 60s to low 70s yet again. Confidence: Medium

Friday and the weekend bring some hotter air back into the area with low-to-mid 90s most likely. I’m still a tad worried we could find our way to the mid-to-upper 90s after Friday, but at least I don’t see any 100+ temperature repeats for now if that is any marginal consolation. Moderate humidity levels are expected. We have a running 20-30% chance of thunderstorms through the period as we don’t expect any major weather systems. Lows each night should range from near 70 in the suburbs to the middle 70s in the city (yeah, that’s more muggy again). Confidence: Low-Medium
