Today’s Daily Digit

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

Temperatures are still on the comfy side, but we’ll notice the higher humidity even if still quite tolerable.

Express Forecast

Today: Partly sunny, more humid. Passing shower? Highs: Low 80s.

Tonight: Mild and muggy. Slight chance of shower. Lows: Upper 60s to low 70s.

Tomorrow: A bit warmer. Isolated late-day storm? Highs: Low-to-mid 80s.


All good things must come to an end, and we’re seeing that end in sight as we close out the weekend. After this fine stretch of weather bliss in the middle of July, summer starts to make a comeback today in the form of rising humidity. Temperatures are slower to respond, but by midweek we’re back into the 90s with the humidity back to its usual muggy self.  Shower and storm chances increase toward midweek as well, thanks to an approaching front, which could bring another shot of brief relief as we head toward next weekend.

Today (Sunday): Flow from the east early on keeps us in the clouds, but as winds turn more from the south late in the morning and through the afternoon, we should break out into some more sun, so we’ll call it partly sunny overall.  The sun is nice but the southerly flow that helps bring it about also increases the humidity, as dew points climb into the low-to-mid 60s. Temperatures are still pretty comfortable, though, with highs mainly in the low 80s. We’ll watch for a 25% chance of an early-morning and/or late-day shower, but most of the day should be dry. Confidence: Medium-High

Tonight: Can’t rule out a passing shower during the evening or overnight with a continued 25% chance, perhaps better odds south and west of the area. Rising humidity and still air make for a warm summer night, reminding us that it is July after all.  Skies are mostly cloudy and lows only drop to the upper 60s to low 70s. Confidence: High

Tomorrow (Monday): High pressure off the Northeast coast provides a continued onshore flow, which keeps the heat in check. That means highs only a touch warmer in the low-to-mid 80s. But with the moderate to high humidity (dew points in the upper 60s) it still feels plenty warm regardless. Skies remain partly sunny and we’ll need to watch the chance of an isolated shower or storm popping later in the afternoon and moving our way from the west. Confidence: Medium-High

Tomorrow night: Any of those isolated showers or storms should quickly diminish after dark, leaving us partly to mostly cloudy through the night. Light winds trend toward calm as well, and lows make a return visit to the upper 60s to low 70s. Confidence: Medium-High


Summer makes a stronger showing on Tuesday as heat and humidity continue to feed into the mid-Atlantic. Sunnier skies emerge and help pump highs to the upper 80s, perhaps near 90 in spots. The chance of a few showers and storms increases but not by much, with a 30% chance during the afternoon into early evening, especially south and west of D.C. Tuesday night features partly cloudy skies and lows in the low-to-mid 70s. Confidence: Medium

Temperatures and humidity continue to climb into Wednesday, and as a cold front begins to approach from the west, thunderstorm chances increase as well.  Clouds bubble up as the mercury rises and we’re looking at low-to-mid 90s for highs. With all that heat and humidity, and enough upper-level energy from the approaching system, afternoon thunderstorm chances rise to 50-60% to the west and 30-40% for the immediate area. Confidence: Medium
