April 27 2011 – Before, During, and after Tornado Outbreak in Georgia and Alabama

Like others, I have a lot of stuff in files from April 27 2011. Here is what I have on this blog beginning on April 22 2011 and ending on May 2 2011. These are excerpts from the linked post where more information and images can be found.

Friday, April 22, 2011 – My first post hinting of what was to come – Easter and beyond

Next week there looks to be another round of storms by Wednesday. Haven’t narrowed down the specifics yet as to whether they will be severe or not.
Current Bufkit soundings hint at the possibility Wednesday evening and night, with high cape helicity values and shear. At this time it appears the further north, the stronger these storms will be.

We’ll know more as time goes as that system is still 5 days away.

Saturday, April 23, 2011Midwest possible flooding next week

I’ll be watching this system for impacts on the local area as it develops. It’s still looking to be a strong one.

Sunday, April 24, 2011Severe weather probable Wed. April 27 Thurs. 28

Models still indicating probable severe weather heading for our area Wednesday PM into Thursday AM. The exact timing is still in question, so keep abreast of the situation.

Best guess at this time:

Latest run of the GFS shows the brunt of activity around 11 pm ET Wednesday, indicating strong possible damaging wind and potential hail as main features. Cape and helicity values are highest at this time with cape:1338, Helicity:418, a Cins of 8, and an energy helicity index of 3.495525. Due to these factors, and a looping hodograph, a rogue tornado at this time can not be ruled out entirely with the passage of this system, which will spawn supercells ahead of the approaching cold front.

Monday, April 25, 2011Severe storms still on track for Wed. April 27 Thurs. 28

This past Friday I mentioned “it appears the further north, the stronger these storms will be”, this still appears to be the case for the local area. However … this does not mean the local area will not see strong to severe storms. Models are still showing this system has the potential of damaging winds, hail, and the capability of spawning a tornado.

None of this is set in stone as we are still 48+ hours away from the occurrence of this event. We are right on the fringe as models show areas to the south of the local area having a more stable environment as the front moves closer to the area. This does not mean those areas wont see strong storms. So don’t let your guard down.

One thing the models [that I use] have done as they get a better handle on this system, they show it coming through the local area earlier that previously forecast. It’s looking more likely the worst of the weather will move through the local area late Wednesday afternoon into the evening, clearing the area early Thursday morning. Thats not to say we wont be seeing any severe weather before the front pushes through, or after with the unstable atmosphere around capable of some regeneration.

Tuesday, April 26, 2011Entering Storm Mode for April 27 – Possible Southeast Tornado Outbreak

At this time it still appears the worst of the storms will stay to our north, as mentioned on Monday. That doesn’t mean we are out of the woods. Hopefully we will not see any tornadoes in the local area, but we all know all it takes is strong wind upwards of 50mph to down trees and power lines causing damage to structures. You may know them as straight line winds, or down burst winds.

Our biggest concern tomorrow will be the development of ‘supercells’ capable of producing tornadoes and severe thunderstorms. We will also have to watch for ‘squall line’ development ahead of the cold front the closer it gets to the area. A ‘squall line’ is also capable of spinning up a tornado, along with severe thunderstorms containing heavy precipitation, hail, frequent lightning, and strong straight line winds.

I can not stress the severity of this situation or adequately without fearmongering.

Wednesday, April 27, 2011Update 1 – Live Blogging: Southeast Severe Weather Outbreak 4/27/2011

Original Post – Jumping right in … Already reports this morning out of North Georgia of Widespread Wind Damage, trees down as well as power lines and damage to structures. The worst report at this time:


Tornadoes have not been confirmed yet in any of the reports, including the above. We’ll know for sure in a day or two.

The storms that caused the damage in North Georgia is the first round. The Second round will come later today and impact a larger portion of Georgia through tomorrow morning, the local area included. The national weather service has revised the time in which these storms will arrive and depart areas of Georgia.


Update: 6:06 PM 4/27/2011 – Just a quick update showing current Weather Warnings, Watches and radar. All of this is moving east and will be affecting the local area later this evening and through the early morning hours.

Thursday, April 28, 2011 – at 5:59 PM EDTSevere Weather Outbreak April 27-28 2011 Aftermath

First, let me apologize for not ‘live blogging’ the event. I became overwhelmed by the destruction and death that occurred in Alabama, as the storms headed for Georgia.

Here in the local area, we were not left untouched by the powerful storm system that moved across the nation causing death and destruction. My home county [ Harris Co Georgia ] had what is yet to be confirmed as a tornado move through. Many areas in Georgia felt the wrath, and many on the east coast are still feeling it.

This tornado outbreak will go down in history as one of few that has claimed so my lives. As it stands at this time, it may be ranked as the second most destructive in the past 50 years. In the coming days, it may find itself being placed as number one ahead of the Super Outbreak of 1974.

I’ll be gathering a few videos and links of damage around the local area in the coming day, and post them here on the blog.

For now, heres a couple radar screen captures showing the storms and tornadoes as they headed for, impacted, and left the area.
