Welcome to cwg.live, updated around-the-clock by Capital Weather Gang meteorologists.
Happening now: A muggy morning with some patchy fog before sunshine breaks through and temperatures advance into the 80s. Afternoon highs are close to 90.
What's next? More heat and humidity on Wednesday with thunderstorm chances. It's somewhat steamy with slight storm chances continuing into the weekend.
Today's daily digit — 5/10: The heat and humidity could be far worse in mid-August, but we were spoiled by that winning beginning. |🤚Your call?
The digit is a somewhat subjective rating of the day's weather, on a 0-to-10 scale.
Forecast in detail
Today (Tuesday): Patchy fog is possible this morning, with partly to mostly sunny skies breaking through for the rest of the day. Highs range from the mid-80s to near 90. Humidity is higher than Monday and quite noticeable, with dew points in the unpleasant low 70s. Light winds from the south. An isolated late-day shower or storm is possible in our far southern and western areas. Confidence: Medium-High
Tonight: Partly cloudy and muggy with lows from 70 to 75. Light winds continue from the south. Skies may be clear enough at times to catch the Perseid meteor shower that peaks this night and tomorrow night. Confidence: High
Tomorrow (Wednesday): Partly to mostly sunny for the morning to midday with more clouds in the afternoon. Scattered showers and thunderstorms are possible in the afternoon as a weak cool front approaches. Highs climb to their highest levels of August so far, reaching the upper 80s and low 90s. Humidity is high with dew points in the low to mid-70s. Winds are mainly from the southwest at about 5 mph. Confidence: Medium-High
Tomorrow night: Evening showers and storms are still possible before partly cloudy prevails. Lows range from 70 to 75 yet again. Confidence: Medium-High
A look ahead
Thursday features a very slight reduction in humidity with partly to mostly sunny skies and highs near 90 degrees. Dew points in the afternoon should range from the upper 60s to near 70. Also, scattered showers and storms continue, especially in the afternoon to evening. Thursday night finds lows in the 70s under partly cloudy skies and light winds once more. Confidence: Medium-High
Friday should be mostly sunny and hot with highs near 90 again, along with moderate to high humidity. A few clouds are possible Friday night with lows in the 70s (upper 60s possible in our cooler areas). Confidence: Medium-High
Our middle weekend of August is a hotter one with highs near or a little above 90 as humidity holds at uncomfortable moderate to high levels. A chance of an afternoon shower or storm exists both days. Saturday night is partly sunny and muggy as lows range from the upper 60s to mid-70s. Confidence: Medium
Next week starts with a hotter, muggier August vibe, but a big cool front sweeping in midweek has the potential to bring significant relief from the heat and humidity. Stay tuned!
