Attack of the Jellyfish Cloud....Just kidding

Attack of the Jellyfish Cloud....Just kidding

Last Tuesday, August 6th, folks around Seattle were enjoying another beautiful, sunny, warm day. However, there were a few unique clouds that interrupted that peaceful day, and had locals wondering what on Earth might be in the sky. "Jellyfish" clouds, as they are sometimes referred to because of their shape, made a rare appearance in Washington. Their technical term is actually "Fall Streaks", which are a form of virga.

Virga, is rain from a cloud, but that rain never actually makes it to the ground because it evaporates too quickly. Fall streaks are similar, but instead of being in the form of rain, they are ice crystals. As those ice crystals "fall" from the cloud they change directly from a solid to a gas state, or sublimination.

Notice in the first picture below that there is one line of "jellyfish" clouds in the western section of the state near Seattle, and another in the eastern section of the state. 

Huge Changes in the Weekend Forecast

Huge Changes in the Weekend Forecast

For the last several days I have been talking about a major rain event across the Metro Atlanta area, well it looks like that might be changing..... The reason for that is an event that we normally see in the fall and winter... The Wedge. 

There are 2 large areas of high pressure to the north which is coming over the northern side of the Appalachians and giving us those strong east winds, stable air, and COOL temps! All that cool air is wedged up against the mountains and spilling down into this area. This has totally shut down the rain machine north of that wedge front today, and it looks like the wedge might hold all the way through the weekend. This will mean that most of the metro area will see clouds and cooler temps through the weekend, with an occasional showers or light drizzle.. 

Heavy rains set to drench area this weekend

ATLANTA - Heavy rains are expected across the state through the weekend, as both a stationary front continues to sit across parts of the Southeast, and a tropical weather system looms in the Caribbean.

11Alive Meteorologist Chesley McNeil says heavy rain is expected across parts of Georgia each day, and that with the already saturated ground, people should be alert for falling trees.

There is a tropical system off of the Yucatan peninsula in the western Caribbean, which over the weekend is expected to move into the warm waters of the Gulf of Mexico. Storm forecast tracks indicate that the disturbance will likely become a tropical storm, but will either move into northeastern Mexico or south Texas.

Atlanta Weather | Thursday's Weather
The tropics are starting to get active, and since the 1800s, we average about 2.8 tropical storms in the Atlantic. There are two systems out there now, one we will be watching closely this weekend that could bring a ton of rain our way.Tropical development in the Caribbean and Gulf has been a concern since early this week, with numerous scenarios still in play. However, meteorologists continue to have more confidence due to the moisture from the storm shifting into the Gulf of Mexico and towards the United States.Once the system moves into the Gulf Thursday night and Friday, it will also be in a rather favorable environment for development. Through the end of the week, water temperatures are expected to stay just slightly above average for this time of year.

Could Worms be Partly Responsible for Higher Greenhouse Gas Emissions??

Could Worms be Partly Responsible for Higher Greenhouse Gas Emissions??

So I am sure you have heard the whole climate change / global warming thing for the last several years... This is not a blog about that... THAT is a totally different can of worms (pun intended). The whole theory behind "Man Made Global Warming" is that we are dumping massive amounts of greenhouse gasses, mainly CO2, into the atmosphere.

Atlanta Weather | More Rain Coming

Unfortunately when it rains, it pours..... That's what will be happening again in the Atlanta metro area starting later tonight thanks to stalled out front to the south, and a tropical system to the south near the Yucatan Peninsula. Now it is too early to tell exactly what is going to happen with this thing long range, but for the short term it is going to fling a lot of tropical moisture into the Gulf of Mexico that will be hooking up with the stalled out front to the south. If you look below you will see one of the satellite movies called the water vapor is pumping a lot of moisture in this direction already.
