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

8/10: Loving bearable, less-muggy warmth. Any lingering gray skies early shouldn’t bother us most of the day.

EXPRESS FORECAST

Today: Sunshine. Highs: Low-to-mid 80s.
Tonight: Turning cloudier and muggier. Lows: Mid-60s to around 70.
Tomorrow: Increasing clouds but hot. Isolated late-day storm? Highs: Around 90 to low 90s are most likely.
Sunday: Partly sunny. Isolated storm? Highs: Wide range of mid-70s to mid-80s.

FORECAST IN DETAIL

Early summer warmth today turns to mid-summer heat tomorrow. Hazy, hot, humid is on tap, but we could get less warm again Sunday and Monday. If outdoors this weekend, note some shower and storm chances peppered in the forecast — rain we can still use.

Today (Friday): Sunshine returns and we get warm — into the low-to-mid 80s. Breezes are occasional, fairly light, and variable in direction. Enjoy the lower humidity levels, as indicated by lower dew-point readings in the 50s! Confidence: Medium

Tonight: Clouds are slowly on the increase. We may be able to see, earlier on, the slimmest of crescent moons and Mars in the western sky. Light southerly breezes around 5 mph help pump in muggier dew points in the mid-60s. Low temperatures around 70 are possible downtown, with mid-60s probable outside of the Beltway. Confidence: Medium-high

Tomorrow (Saturday): Prepare for serious heat, at least 20 degrees above average. High temperatures likely get to around 90 to low 90s for many of us. I think with southwest winds near 10 mph for much of the day, sticky heat may reign. We may see some cloud increase late, and an isolated thunderstorm is possible given the heat and humidity. Confidence: Medium

Tomorrow night: If any isolated storms pop up, they die off with the loss of sunshine. Northern suburbs may have highest shower/storm chances. Low 70s are possible downtown before dawn, with upper 60s being about as low as suburbs can reach. Skies are variably cloudy. Confidence: Medium

A LOOK AHEAD

Sunday: We could see a very weak cold front come off of the cooler Atlantic on Sunday. An east-southeast breeze could help keep temperatures in the mid-70s east of town, with low 80s still possible around town and to the west and southwest of town. Cannot rule out mid-80s if this front doesn’t make it all the way through the region, thus lower forecast confidence. We need to watch where it sets up. If the front is still northeast of us by afternoon, an isolated storm risk may develop. Still, a decent day to enjoy flowers! Confidence: Low-medium

Sunday night: Could be a mix of clouds and stars. Only a slight chance of the briefest of passing showers. Overnight low temperatures could briefly dip in the pre-dawn hours down into the mid-to-upper 60s. Confidence: Medium

Associated with our next cold front, Monday and Tuesday could be windy. Southerly winds could gust over 20 mph during a somewhat cloudy May Day, with high temperatures in the 80s and storms possible by day’s end. Westerly winds behind the cold front on Tuesday may not be quite as strong, but they bring in drier air, comfortable air with mid-to-upper 70s possible for our high temperature range. Looks sunnier than Monday, too! Wear that sunscreen. Confidence: Medium
