When Lightning Strikes a Person

When Lightning Strikes a Person

What you are looking at above is called Lichtenberg figures and it happens when a person is struck by lightning. The name comes from the German physicist Georg Christoph Lichtenberg who studies fractals caused by electrical discharge. He noticed that when lightning struck something, it always discharged in a fractal manner... In other words as all the electricity was trying to dissipate, it branched out and branched out and branched until the charge was gone. He studied this on insulated objects and the ground, but later it was discovered that it happened in people too!

Severe Storms Popping Up Across Metro

Severe Storms Popping Up Across Metro

A very slow moving front is now moving through N Georgia this afternoon and is helping to focus all the moisture and instability across the area. Severe storms have popped up across the metro and will continue to pulse up and down until the sun goes down. The front is oriented from the NE near Clayton to the SW near LaGrange. The latest computer models are showing these storms slowly winding down around 7pm tonight. If you do get under one of these storms you can expect frequent lightning, heavy rain, and in some of the stronger storms there could be some small hail. I'll keep you posted!

Atlanta Weather | Rain Chances This Weekend

Atlanta Weather | Rain Chances This Weekend

Unfortunately more rounds of rain and the possibility of flash flooding will continue this weekend due in part to the remnants of Chantal.
An upper low, positioned over the Tennessee Valley today will retrograde West Saturday bringing in a flow of moisture from the Gulf of Mexico and the Atlantic Ocean. The flow of moisture will increase our chances for rain which could be heavy at times.
The ground is saturated throughout the state, so any amount of rain will cause flash flooding in some spots. At this time it appears the heaviest showers could be around on Sunday. Temperatures will be below average due to the increased cloud cover and rain.
Skies will dry out as we head into next week.

How the Remnants of Chantal is Changing the Forecast for this Weekend

How the Remnants of Chantal is Changing the Forecast for this Weekend

Ughhhh, I know this is not what you want to hear but there are changes for the worse for the weekend thanks to the remnants of Chantal. It will mainly affect us staring late on Saturday but it could last through most of Sunday,... Here is the setup and you can follow down below with the images..

Atlanta Weather | Flash Flood Watch Today

Atlanta Weather | Flash Flood Watch Today
A very slow moving cold front will drop into the area today, bringing more showers and thunderstorms. Some of the storms will drop some heavy rain and frequent lightning. A half inch to an inch of rain possible. As much as 2 inches possible in some localized areas. A Flash Flood Watch will remain in effect through tonight. With so much rain, and ground already saturated, it will not take much rain to cause flooding and for some trees to fall.The good news in the forecast is that the front should move far enough south that we will dry out for the next two days. 

A "Chilly" Weekend Morning Coming

A "Chilly" Weekend Morning Coming

The coolest air in quite some time is heading down in this direction and it is going to send parts of N Georgia into the upper 50's for overnight lows. No, I am not talking about Atlanta, we will be seeing overnight temps for Friday night into Saturday morning into the mid 60's. But in the mountains like Clayton, Blue Ridge, and Ellijay they could see temps in the upper 50's by early morning!! Highs Saturday afternoon will be in the mid 80's with low humidity as well!

Storms Rolling in from Tennessee

Storms Rolling in from Tennessee

There are some big pre-frontal storms that are moving in from TN tonight that contain very heavy rain, gusty winds, and intense lightning. At the last check the storms had 1900 strikes in 15 minutes. Although these storms have increased a bit in intensity and might even pulse up a bit more in the next 15-20 minutes, I expect them go go through a major weakening trend as they drop south. There are 3 main reasons:

#1 Look below at the chart labled "Cape", this is instability and you can see that it goes way down as it gets closer to the metro area. This will allow those storms to weaken.

#2 Upper level winds are garbage, and they converge over the metro area.... in English what this means is the winds slow down as you go towards the south in the mid levels. That means through conservation of mass the air must go down, limiting storms from getting stronger.
