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

Well into the 80s, but otherwise a lot like Tuesday with plentiful sun and dry air. Sure beats the heat to come. Get the Digit on Twitter| Discuss on Facebook


Summer sizzle is on its way back. But at least it’s nice enough to allow us a gradual transition. The warm-up starts today, but we probably don’t break 90 until tomorrow, and the humidity shows some restraint until Friday. Starting Friday, though, the heat and humidity team up for a one-two punch straight through the weekend (not great timing for Tiger’s Tourney at Congressional). Any chance of a cooling thunderstorm?...

Today (Wednesday): After yesterday's Perfect 10, at least as far as the Daily Digit goes, today features warmer air with highs in the upper 80s. But the humidity is still low and skies are mostly sunny, not to mention a nice breeze from the northwest near 15 mph. So it’s hard to find much fault, especially given the high heat on the way. Confidence: High

Tonight: Humidity starts to creep up but it’s still a very comfortable evening and not a bad overnight. Skies remain mostly clear as lows dip to the 60s (suburbs) to near 70 (downtown). Confidence: High

Tomorrow (Thursday): Bad news is the 90s are back thanks to warm breezes from the southwest and mostly sunny skies. Good news is it’s the low-to-mid 90s, and humidity is still on the low-to-moderate side, though higher than today. Confidence: Medium-High

Tomorrow night: Humidity makes a more modest jump as we go through Thursday night. Also, can’t rule out an isolated shower or thunderstorm. Lows probably stay up in the 70s area-wide under partly cloudy skies. Confidence: Medium


The heat wave hits its stride Friday, Saturday and Sunday. All three days should be partly to mostly sunny and plenty hot with at least moderate humidity. That means highs in the mid-90s to near 100, and afternoon heat indices spiking to near 100-105. An isolated thunderstorm or two is possible each day. Confidence: Medium

For those interested in tracking, here are the record highs for Friday, Saturday and Sunday... National: 101, 100 and 102; Dulles: 95, 98 and 94; BWI: 105, 100 and 103.
