Today’s Daily Digit

A somewhat subjective rating of the days weather, on a scale of 1 to 10.

It’s sticky, and there may be a storm…but still not Washington’s worst when it comes to mugginess.

Express Forecast

Today: Partly sunny, 30 percent chance of storms. Highs near 90.

Tonight: Partly cloudy, 30 percent chance of storms. Lows 66-72.

Tomorrow: Partly sunny, 20 percent chance of storms. 90-94.


Some of the summer’s stickiest weather to date subsumes us this week with tough to dislodge heat and humidity. The juiced up atmosphere fuels hit or miss late day storms most days, but it’s dry more often than not. By the weekend, we cool down a notch, but can’t shake the storm chances.

Today (Monday): Some patchy early morning fog is possible; otherwise skies are variably cloudy with periods of sunshine. Scattered thunderstorms are possible (30 percent), with the best chance in the late afternoon (but not out of the question prior). It’s plenty humid (dew points 66-69), with highs around 90. Winds are from the southwest at around 10 mph. Confidence: Medium-High

Tonight: Evening storms are a possibility (30 percent chance). Otherwise, it’s your typical muggy D.C. summer evening, with partly cloudy skies and lows in the mid-to-upper 60s in the cooler suburbs to the low 70s downtown. Winds are light. Confidence: Medium-High

Tomorrow (Tuesday): We crank up the heat a bit more, with highs climbing into the low-to-mid 90s. Yes, factoring in the humidity, it may feel like the upper 90s mid-to-late afternoon. A few of us may get cooled off a bit by a pop-up thunderstorm (20 percent chance). Confidence: Medium-High

Tomorrow night: A few storms may linger into the evening hours (20 percent chance). Otherwise, here we go with another muggy evening. Overnight lows range from the upper 60s in the cooler suburbs to the mid-70s downtown. Confidence: Medium-High


Wednesday and Thursday are both hot and steamy, with humid air continuing to get pumped in from the south. There won’t be a much of a trigger for late day storms, but they can’t be ruled out (20 percent chance). Highs both days should be in the low-to-mid 90s, under partly sunny skies. Overnight lows are mostly in the 70s. Confidence: Medium

A cold front marches into the region Friday, bringing an increased chance of showers and storms, especially in the afternoon and evening hours (at least 50/50 odds). Highs probably near or pass 90, with plenty of humidity. Storms may well linger into the evening hours, followed by partly cloudy skies and lows in the upper 60s to low 70s. Confidence: Medium

I’m not sure we can kick the heat and humidity and storm chances out of the region by Saturday, as Friday’s front may stall out in the region. Skies are probably variably cloudy, with highs in the mid-80s to near 90; storm chances may be in the 30-40 percent range into the evening. Somewhat drier air may start to seep into the region Saturday night with lows in the mid-60s to low 70s. Confidence: Low-Medium

Sunday is probably not as hot or humid as previous days, but a bit of humidity may still linger, and I can’t remove the chance of a late day shower or storm (20-30 percent chance). Highs are most likely in the mid-to-upper 80s. Confidence: Low-Medium
