Who is going to get a WHITE CHRISTMAS?

This year lots of people will get a WHITE CHRISTMAS!  Including Texas… cool right?  I’m looking at the weather forecast right now. Back to the weather… Salt Lake City: snow. Also if you are by high elevation you will get more snow. Up by Richmond, Virginia: rain… this is weird around Houston, Texas because of a severe weather alert and  lots of wind, rain and maybe even  some snow!  The jet stream has dropped down by the panhandle of Texas and the warm air  from the Gulf of Mexico has come up so… when warm air mixes with cold air sometimes makes tornados AHHHHH! NO! Ugh, not so good. Why is the northern part of Texas getting a WHITE CHRISTMAS? Because the earth goes around the sun so sometimes it is close to the sun sometimes it is far away from the sun. We are on the far side of the sun where it is cooler in the north part of the earth.   Wow that was a lot of explaining .  There is also an unnamed storm that will move past Salt Lake City then move down to Oak city. I mean Oklahoma city. Mississippi chance 5 percent for tornados.  Georgia and Florida, 3 percent for tornados. Let’s hope that doesn’t happen.

If you get a chance., let me know if you got a WHITE CHRISTMAS where you live.

Weather Halos: Sun and Moon

Weather halos are produced by ice crystals high in cirrus clouds 3-6 miles above the earth.  Light passes through ice crystals, appearing as a halo.  When they appear, they are usually seen around the sun or the moon, but might appear elsewhere in the sky.  The can also form around artificial lights like light pole lights.   But the weather needs to be very cold and  ice crystals called “diamond dust” need to be floating in the nearby air.

St. Elmo’s Fire — Not the movie!

St. Elmo’s fire is a bright blue or violet glow that usually appears on a sharp object like a lightning rod, ship’s mast, church steeple, chimney or airplane wings.  Even leaves, grass or cattle horns can show St. Elmo’s Fire.  It can sound like a hissing sound or a buzzing sound. St. Elmo’s Fire is a mixture of gas and plasma.  The electric field around the structure cause air molecules to ionize a faint glow, easily seen in low light situations.  The presence of  hydrogen and oxygen in the earth’s atmosphere causes the blue or violet color.
