Rain-showers and thunderstorms dumped a significant amount of water today along the Cumberland Plateau. Flood Advisories were out for several counties in the area this after with estimates of 2-3″ of rain. In the wake of that rain this appeared.
Meanwhile most of Middle Tennessee enjoyed sunshine and slightly lower humidity.It was still hot, Nashville reached 92 degrees.
The tiny humidity break won’t last long, a trough of low pressure will take over, bringing a chance of rain and thunderstorms each day. The severe threat is low, but there is the concern of heavy downpours leading to localized flooding. Afternoon highs will be near 90 degrees, which is average for this time of year.
The clouds that will come with this on and off rain pattern may be an issue for sky watching this week and there is lots to see. Tonight the moon is beautiful, but it will have company as the week goes on. After the sunsets Wednesday, Thursday and Friday, the waxing gibbous moon will be shining near planets Mars and Saturn, and the star Antares.
The moon will set before the predawn hours on Thursday, Friday and Saturday, that is good news because the is the time the Perseid meteors typically streak across the dark sky in their greatest numbers.
The Perseid meteor shower peaks predawn on August 12. Not only is this typically among the best meteor showers of the year, this year’s show is anticipated to be among the best. The Perseids are the result of Earth passing through dust particles left by comet 109P/Swift-Tuttle during previous passes through the Solar System. Jupiter’s gravity has nudge several streams from hundreds of years ago closer to Earth’s path around the sun this year. Meteors have already been observed for the past week or more. The latest predictions are in the neighborhood of 150 meteors visible per hour from a dark area.
Just keep in mind the clouds could be an issue. Happy viewing.
