May 8-9 Potential Midwest/Great Lakes Severe Storm System (Issued April 30)

There is concern building for a potentially significant severe weather event May 8-9.
 We will see a strong low pressure system drop from Canada into the Upper Midwest. The low will bring with it a supply of cold air. This image is for the period May 8th at 7pm CDT.
The above image is forecast for 1 am, May 9. By then, the low pressure will have quickly moved into Michigan. This does not display what is forecast for temperature differences, though.
The image above is still 1 am CDT May 9th, but it displays projected temperature differences 5,000 feet above the ground. As you can see, a rush of cooler air will be following the low, suggesting some form of cold front or force moving the air into the region.
More concerning, though is the temperature differences. It is projected to be a 10 degree temperature difference, which could turn out to be a 15 degree difference on the ground. That is a pretty substantial difference. With such a strong low and big temperature differences, there is definitely concern for tornadoes.
The image above is the Best Lifted Index. The lower numbers, the more unstable. As you can see, here is a noticeable area of instability in Nebraska, with a number of -8. The image above is actually in the time frame of May 8th at 1 am. That displays an able set-up going into the event.

Lastly, also at 1 am May 8th, is the image depicting a cap. A cap suppresses storms, the more negative the stronger the cap. As we can see on this image, the cap is as low as the legend can go, which is -500 to -900. That is an extremely strong cap. It is very worrying, combined with such instability, strong low pressure.

These two images are the jet stream. The jet stream was up to 150 mph on the April 27 tornado outbreak down south. The first image is May 9th at 1 am, while the second is May 9th at 7 am.
We see the jet stream will be fairly strong, at it reaches up to 100 mph in the Ohio Valley.
Finally, above, is the lower level jet stream forecast at May 9th at 1 am. The lower level jet stream will not be terribly strong, meaning the tornado threat should not be as strong as it was on April 27.
In conclusion, there is a threat for a tornado outbreak and severe weather, but it would not be nearly as strong as April 27.

April 30: Tonight's Thunderstorm Forecast

The image above is for 9:00 pm CDT tonight. At 9pm, we expect storms to gradually develop in West Tennessee and into Arkansas. This will be due to a cold front pulled by a low pressure system in Canada. The cold front will also initiate some weaker storms in Wisconsin into Illinois.
Looking ahead to 11:00pm CDT tonight, the storms will increase in Wisconsin and a bit more into Illinois. More interestingly, there will be stronger storms in West Tennessee and West Kentucky. The storms will also increase in coverage in Arkansas. Some spotty showers are possible into Texas as well.
The above image is valid at 2am CDT. As the cold front continues to move east, the storms will increase in coverage and strength, especially in the Northern portion. The best probability of storms will be in West Tennessee and West Kentucky. Probabilities will reach up to 90% in the Michigan area into Indiana. Spotty storms will be possible into Texas.

April 27 Historic Tornado Death Toll Continues to Climb (April 30)

The death toll from the April 27 tornado outbreak has risen to 355 people dead.
The National Weather Service also reported 211 confirmed tornadoes on that horrible day.
There were the most deaths in Alabama, with 254 deaths reported.
Tennessee and Mississippi followed respectfully in 2nd and 3rd place, each with 34 deaths.
In 4th place came Georgia with 15 deaths.
Arkansas- 11
Virginia- 5
Kentucky and Louisiana each had 1 death.

April 30: Daytime Thunderstorm Forecast

The image above is for around 4:00 pm CDT. We do see some storms beginning to develop in the Southeast Arkansas/North Louisiana area around this time as a strong low pressure in Canada with a trailing cold front works its way across the South US. There will also be some isolated storms in South Florida.
This cold front will cross the entire US, pretty much for everyone east of the Mississippi River.
However, with a more ample supply of humid air down south, there is a slight risk of severe storms. A tornado outbreak is not expected. Below is the slight risk area.
The slight risk extends through the following areas:
-Extreme South IL
-Extreme West KY
-Extreme Southeast MO
-Much of Arkansas
-Extreme West TN
-Extreme Northwest MS
-Portions of North TX
-Extreme Southeast OK

There will also be a threat for plain thunderstorms in green, but again, the supply of humid air will keep south, thus the slight risk.
This is an image of the probability of thunderstorms for 6:00 pm CDT today. We see a much more defined area of potential storms in Arkansas, where the highest percentage threat of REGULAR thunderstorms is up to 95%.
By the way, I don't know why this map has percentages over 100. I didn't make the map, so unfortunately I can't answer that.
Thunderstorms will be somewhat of an isolated nuisance in Southern Florida while way offshore there will be storms.
Check back tonight for tonight's thunderstorm forecast.

April 29: Tonight's Thunderstorm Forecast

The thunderstorm forecast for tonight is very low as a weather disturbance comes through the Upper Midwest. The maximum chances for storms will exist mainly on the US/Canada border in North Dakota. The best chances will be up to 70%, so I would expect some spotty storms.
Storms will be exiting Florida at midnight, which is when this image is valid. Offshore, there will be quite a squall line. It will probably produce ample waterspouts, so ships in that area should watch out.
Everywhere else should be clear of storms.

April 27 Aftermath: How did the Tornado Outbreak occur?

Such an outbreak like the April 27 one is extremely rare and historic when it happens.
The big question is, how did this happen?

1. JET STREAM

The jet stream was down south, guiding the low pressure center east with the cold front that would produce the tornadoes. The jet stream was unusually strong, and the storm system may have even gotten some of that energy from the jet stream.
The jet stream made for a high wind shear event, favorable for tornadoes in some areas.
Additionally, the jet stream separates warm and cold air. With the cold front bringing the cold air from above the jet stream and the warm front bringing warm air from below the jet stream, it was a very volatile situation to start with.

2. EHI
EHI (Energy Helicity Index) combines wind factors (like helicity, which is a spinning motion) and energy factors (like CAPEs, which produce stronger and more volatile storms) to make a sense of what the potential is for rotating supercells.
The EHI index was incredibly high for the outbreak.
Values may have reached 12.00, which is considered absolutely unbelievable.
This is probably the biggest factor that directly contributed to the tornado outbreak.

3. CAPE
CAPE values indicate potential energy that can be utilized by thunderstorms. The higher the CAPE, the more unstable the atmosphere. CAPE values were witnessed to be up to 4,000 j/kg, possibly even more.
To give you a sense of how unstable 4,000 j/kg is, 2,000 j/kg is considered the threshold for severe thunderstorms for CAPE values.

There were many other things that came into place, but these 3 really stood out from the other factors.
Stay tuned to the Weather Centre for continuing coverage on the aftermath of this horrific incident.

Death Toll from Historic April 27 Tornado Outbreak Spikes

The death toll from last night's tornado outbreak has unfortunately spiked.
At least 173 people are confirmed dead.
Mississippi: 32
Alabama: 128
Dekalb County in Alabama was the hardest hit, with 30 people dead there alone.
There are also fatalities in Arkansas, Georgia, Tennessee.

A witness to the tornado that hit Birmingham indicated it was at least a mile wide.
The mayor of Tuscaloosa described Tuscaloosa's infrastructure as 'decimated'.
80,000 chickens escaped as well.

The Weather Centre holds people affected in our thoughts and prayers today.

...OUTBREAK OF SEVERE THUNDERSTORMS AND TORNADOES EXPECTED OVER

   TONIGHT...
   
   THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE
   DEVELOPMENT OF A FEW STRONG TO VIOLENT...LONG-TRACK TORNADOES OVER
   PARTS OF THE TENNESSEE VALLEY AND SOUTHEAST US THIS AFTERNOON AND
   TONIGHT.
   
   THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE
   
          NORTHERN ALABAMA
          FAR NORTHWESTERN GEORGIA
          NORTHEASTERN MISSISSIPPI
          SOUTHERN TENNESSEE
   
   ELSEWHERE...SEVERE STORMS ARE ALSO POSSIBLE FROM...THE LOWER GREAT
   LAKES REGION AND MIDDLE ATLANTIC TO THE CENTRAL AND EASTERN GULF
   COAST STATES.
   
   THUNDERSTORMS ARE EXPECTED TO ERUPT OVER PARTS OF THE LOWER
   MISSISSIPPI VALLEY BY EARLY AFTERNOON AHEAD OF A POWERFUL STORM
   SYSTEM CURRENTLY OVER THE CENTRAL AND SOUTHERN PLAINS. THE STORMS
   WILL QUICKLY MOVE EAST-NORTHEASTWARD OVER THE TENNESSEE VALLEY AND
   SOUTHEAST STATES THIS AFTERNOON AND EVENING...WITH ADDITIONAL STORMS
   DEVELOPING INTO THE LOWER GREAT LAKES AND OHIO VALLEY REGION. STORMS
   WILL SHIFT EASTWARD ACROSS PORTIONS OF THE NORTHEASTERN...MIDDLE
   ATLANTIC...AND SOUTHEASTERN STATES DURING THE EVENING AND OVERNIGHT
   HOURS. AS THE THUNDERSTORMS ENCOUNTER A VERY MOIST AND UNSTABLE AIR
   MASS...THEY WILL RAPIDLY BECOME SEVERE WITH THE POTENTIAL TO PRODUCE
   STRONG TO VIOLENT...LONG-TRACK TORNADOES...LARGE HAIL...AND
   WIDESPREAD DAMAGING WINDS.
   
   THE MOST INTENSE STORMS ARE EXPECTED ACROSS NORTHERN ALABAMA...FAR
   NORTHWESTERN GEORGIA...NORTHEASTERN MISSISSIPPI...AND SOUTHERN
   TENNESSEE. A HIGH RISK FOR SEVERE THUNDERSTORMS IS IN EFFECT FOR
   THESE AREAS. FUTURE FORECASTS MAY EXPAND THIS AREA TO INCLUDE
   PORTIONS OF EASTERN TENNESSEE...AS WELL AS AREAS FARTHER SOUTH INTO
   EASTERN MISSISSIPPI AND WESTERN ALABAMA.
   
   STATE AND LOCAL EMERGENCY MANAGERS ARE MONITORING THIS POTENTIALLY
   VERY DANGEROUS SITUATION. THOSE IN THE THREATENED AREA ARE URGED TO
   REVIEW SEVERE WEATHER SAFETY RULES AND TO LISTEN TO
   RADIO...TELEVISION...AND NOAA WEATHER RADIO FOR POSSIBLE
   WATCHES...WARNINGS...AND STATEMENTS LATER TODAY.

Back-To-Back high risk situations issued- April 27
