January 29: Winter Rollercoaster…Moon

Cold air returning to Middle Tennessee along with some snow, but that is not an indication of the weather for the week.  It will be quite the roller coaster ride with spring like temperatures and two more chances of snow over the next 7 day.

Today the high in Nashville was at 51°, but that occurred early at 1pm. Since then cold air has blasted into Middle Tennessee, even producing some snow.

The sky will clear overnight and tomorrow will be sunny, but chilly, only reaching the low 40s.  Wednesday, a south wind kicks in warming things again.  On Thursday, rain showers will return.  Thursday night, rain has the potential to turn to a brief period of snow, especially north and east of I-24.  Best chance of accumulating snow will be over south central Kentucky and on the Cumberland Plateau. Friday will be cold, as clouds exit.

One forecast that is looking good is the forecast for the Super Moon Eclipse that will happen Wednesday morning. A supermoon is the name given to the Moon that is full when it is also at or near its closest point in its orbit around Earth, called the perigee. This close encounter makes the Moon appear about 14% bigger and 30% brighter.

Now for the Eclipse part, the Moon’s orbit around our planet is tilted so it usually falls above or below the shadow of the Earth. About two times a year, a full Moon lines up with the Earth and Sun in such a way that the Earth’s shadow blocks the Sun’s light. That light would normally reflect off the Moon. Here in the Eastern part of the U.S. we will only see a partial eclipse. But it should be a really cool sight because it’s the Blood Moon. It’s call that because it will take have a fainter glow than usual because less sunlight will make it’s way through the Earth’s atmosphere at that angle. The way the atmosphere bends light the Moon will have a red glow, hence the Blood Moon.

Just to add another color description to the Moon since it is the second Full month in the month, it is also called the “Blue Moon”.

How about this, the eclipse of a “Super Blue, Blood Moon”. The partial lunar eclipse starts at 5:48AM Wednesday.
