D.C. area forecast: Still sunny and dry for Sunday, then hot stuff heads back to town

Today’s Daily Digit

A somewhat subjective rating of the day’s weather, on a scale of 0 to 10.

Turning warmer. But a sunny, dry, long weekend feels even nicer when sandwiched by summer heat.

Express Forecast

Today: Staying sunny, a bit warmer. Highs: Upper 80s.

Tonight: Partly cloudy and milder. Lows: Mid-60s to low 70s.

Tomorrow: Building summer heat. Isolated late-day storm? Highs: Low-to-mid 90s.


Once again the weekend turns out fabulous only to turn less than ideal for the rest of the week. I’m sure there are few complaints, though, as this time it’s a long weekend to boot. Today is noticeably warmer than yesterday, but it’s a nice one nonetheless with humidity still in check. The same cannot be said as we head into the work week. Flow from the south and southwest pumps in the heat and humidity ahead of a midweek cold front, raising the chances for showers and storms by Tuesday and Wednesday.

Today (Sunday): High pressure to the south starts to usher a bit more heat and humidity into the region, but all in all, it’s still nicer than the norm for this time of year.  Skies stay sunny with only a few stray clouds from time to time during the afternoon. Afternoon highs climb mainly to the upper 80s, with a reading of 90 not out of the question, as winds come from the south near 10 mph. Confidence: High

Tonight: Humidity creeps a bit higher, and with light winds from the south-southwest not providing much relief, it’s likely time to crank the A/C back on if you made it through the day without it.  Skies stay mostly clear, with perhaps a few more clouds moving through toward morning. Overnight lows turn a bit milder, ranging from the mid-60s to low 70s (suburbs to city). Confidence: High

Tomorrow (Monday): A warmer flow from the southwest brings summer heat back into play as highs head for the low-to-mid 90s. The humidity is a bit higher but still tolerable. A disturbance to the northwest may send a few more clouds overhead during the day, but on the whole it’s still more sunny than not. Most shower and thunderstorm activity should stay well to our west and northwest, but we’ll mention a 20% chance for a shower or storm closer to home. Confidence: Medium-High

Tomorrow night: That 20% chance of a shower or storm remains through the first half of the night, before leaving behind just partly to mostly cloudy skies.  The majority of the night stays stuffy and still, with only a light wind from the southwest offering relief from the mugginess, as lows only drop to the low-to-mid 70s. Confidence: Medium-High


The 3 H’s return in full force on Tuesday (that’s hazy, hot and humid, in case you forgot) as we bake under mostly to partly sunny skies. Highs likely reach the mid-90s, and the heat and humidity could provide enough fuel for a few scattered showers and thunderstorms (30% chance) late afternoon into evening. Tuesday night stays warm and muggy with lows in the low-to-mid 70s again. Confidence: Medium-High

A cold front slowly working through the area on Wednesday creates cloudier conditions that keep temperatures in check, but also provides a focus for showers and storms. Rain chances increase to 50% for the day overall, with the highest likelihood mid-afternoon into evening. With only periodic breaks of sun, highs are still warm, but only reach the upper 80s to low 90s. Confidence: Medium
