PM Update: Dose of summer heat returns; Sea level rise briefly curtailed by Australia rain

After six straight days of cooler than normal August weather, the heat mounted a comeback today, with highs in the mid-to-upper 80s.  The humidity rebounded as well. For Wednesday, we’ve got another warm to hot day and can’t rule out a late day storm.

Through Tonight: It’s your classic D.C. mid-summer night.  It’s partly cloudy and humid, with enough clear sky to spy the “alternative” Blue Moon.  Lows range from the low 70s downtown to the mid-to-upper 60s in the cooler suburbs.  Winds are light.

Tomorrow (Wednesday): Much like today, it’s partly sunny, very warm and humid, with highs in the mid-to-upper 80s.  We might see an isolated thunderstorm or two pop up (10-20 percent chance), but I tend to doubt it. Winds are from the south at 5 to 10 mph.

Extreme rains in Australia briefly reduced global sea level: In 2010 and 2011, it rained so much in Australia, that the water removed from the surrounding ocean and deposited onto the land caused the sea level to fall on a global scale according to new research.  “The 2010-11 event temporarily halted a long-term trend of rising sea levels caused by higher temperatures and melting ice sheets,” reports the National Center for Atmospheric Research.  More information here: Global sea level rise dampened by Australia floods
