Weather Headlines

–Rain showers for today, especially south of I-40

–Mostly cloudy skies to rule the weekend weather

–Rain moves in after dark Sunday and stays through Tuesday

–Turning much colder Tuesday night through Thursday

–Milder weather expected by the end of the week

Main threats

The greatest threat in the 7-Day outlook is the bitter cold air coming Tuesday night through Thursday. Just be prepared for that change in temp. This will be tough on outside furbabies, after this stretch of mild weather. Make sure they’re taken care of.

Summary

We’ll see some scattered showers today, mainly in the afternoon and mainly along and south of I-40. Rainfall amounts should be light, ranging from 0-0.25 inches.

This system moves out by tonight but leaves behind a lot of clouds. Those cloudy skies will be with us through Sunday. It’s not out of the question that we could see some peaks of sun from time to time, but skies should remain mostly cloudy.

The next significant storm system moves in Sunday night, with rain showers developing in the overnight hours. That rain will persist and become heavier and more widespread through Monday and Tuesday. After a very strong arctic front pushes through, precip will quickly come to an end. Never the less, a few flurries could remain for late Tuesday night. No accumulation is expected at this time.

All indications point to this being a quick shot of arctic air, with temps warming back to around 50 by Friday.

Records

A severe windstorm struck the nation’s capital on this day in 1970. The wind became so fierce that it toppled the National Christmas Tree at the White House!

On this day in 1886 the Appalachian Mountains were buried beneath a major snowstorm. Three days worth of snow left 25 inches at Rome, Georgia, 33 inches at Asheville, and 42 inches on numerous other mountains. Columbia, South Carolina measured two inches of sleet!

Friday Funny Day!

Q: What did the hail storm say to the roof?

A: Hang onto your shingles, this will be no ordinary sprinkles!

NASA Knowledge

Engineers will be pushing the world’s largest rocket fuel tank beyond its design limits at the Marshall Space Flight Center in Huntsville. This is one of the sites I got to visit this past summer during a NASA Meetup that I was selected for. They are testing this tank in this way so that will be as safe as possible when we use it to help boost us to the Moon.

A series of 37 tests will be performed. They will test the stress of liftoff and flight. This core stage is 130 feet tall, 27.6 feet in diameter and stores 537,000 gallons of super cooled liquid hydrogen. This is the fuel tank that is used in the first eight minutes of flight.
