(From Twitter user @wxdam, a debris ball signature is on radar as the EF4 tornado hits Louisville, MS.)

On the afternoon of Monday, April 28rh a EF 4 Tornado struck Louisville and Renfroe, MS in Leake, Neshoba, Attala and Winston County. This tornado produced a large area of EF-2 to EF-4 damage along its path. Hundreds of structures were heavily damaged and thousands of trees were snapped and uprooted. A door from a building in the community of Louisville landed on the campus of Mississippi State University in Starkville.

The EF-4 damage consisted of several homes and apartments that were literally reduced to slabs, industrial buildings that collapsed, chicken houses that were completely destroyed with little trace left of them. Debarked and denuded trees and a collapsed cell tower were also noted.

Below is information from NWS Jackson, MS on the strength of the tornado

Rating: EF-4
Estimated Maximum Wind:  185 mph
Fatalities/Injuries: 9 fatalities and unknown Injuries
Damage Path Length:  35.5 miles
Maximum Path Width: 3/4 mile

The Mayflower-Vilonia, Arkansas tornado that struck on the evening of Sunday, April 27, has been given a final rating of a high-end EF-4 on the Enhanced Fujita Scale.

Officials with the National Weather Service made the announcement Wednesday evening at a news conference at their office in North Little Rock, AR.

According to officials, this tornado started West of Ferndale and ended in El Paso.  It was on the ground for 41.3 miles and lasted more than an hour. This tornado reached its maximum strength near Downtown Vilonia.

NWS survey teams revisited a few damage spots in Mayflower and Vilonia earlier today before deciding and making the final determination.

This tornado is also being blamed for the first death ever from someone taking shelter in a safe room designed to withstand tornadic winds.

Here’s a write up that the Weather Channel did.

Tornado ‘Shredded’ Cars, Trucks and 18-Wheelers

The Arkansas twister shredded cars, trucks and 18-wheelers stuck along Interstate 40 north of Little Rock. After the storm passed, tractor-trailer rigs tried to navigate through the damage to continue their journeys, while gawkers held smartphones to their windows to offer a grim glimpse of the destruction.

State troopers went vehicle-to-vehicle to check on motorists and found — with genuine surprise — that no one was killed.

“About 30 vehicles — large trucks, sedans, pickup trucks — were going through there when the funnel cloud passed over,” said Bill Sadler, a spokesman for the Arkansas State Police.

The Red Cross has opened emergency shelters at St. Joseph’s Catholic Church in Conway and Beryl Baptist Church in Vilonia.

Four other Red Cross-supported shelters are also open. In Conway, they are located at Antioch Baptist Church, Oak Bowery Baptist Church and Point of Grace. A shelter is also available at Mayflower Middle School.

The shelters are providing cots, blankets and food for the displaced residents.”

Oklahoma City Severe Weather Threat Through Sunday (4-22-2014)

A multi-day severe weather outbreak is possible. Wednesday will be day one of this outbreak for Oklahoma. The tornado threat is next to zero, however along and west of I35 will have the best chance for severe weather on Wednesday. Large hail to golf ball sized and winds to 70 mph will be possible.

image

Then we will skip a couple of days and go to this upcoming weekend. Above you see a graphic that shows the severe weather threat this weekend. The purple shows where the best severe weather threat is for Saturday. Sunday’s threat will include part of where Saturday’s threat exists in the purple plus the green shading as well. OKC will be impact both days. A major threat for strong tornadoes will exist too,

Here’s the days 4-8 outlook from the Storm Prediction Center. Note the strong wording this. This could be the biggest outbreak of 2014.

DAY 4-8 CONVECTIVE OUTLOOK NWS STORM PREDICTION CENTER NORMAN OK 0345 AM CDT TUE APR 22 2014 VALID 251200Z – 301200Z

DISCUSSION: SIGNIFICANT MULTI-DAY SEVERE EVENT EXPECTED ACROSS THE SOUTH CENTRAL U.S. SATURDAY AND SUNDAY. STRONG TORNADOES ARE POSSIBLE.

22/00Z ECMWF IS EXHIBITING REASONABLE RUN-TO-RUN CONSISTENCY OVER THE LAST FEW DAYS WITH THE GFS NOW TRENDING TOWARD ECMWF SOLUTIONS. THIS FORECAST IS HEAVILY WEIGHTED TOWARD THE ECMWF. EARLIER CONCERNS REGARDING A POLAR FRONT UNDERCUTTING STRONG SWLY FLOW ALOFT OVER THE SRN PLAINS ARE LESSENING. WHILE UPPER BLOCK OVER CNTRL CANADA WILL ULTIMATELY FORCE A DOMINANT SFC ANTICYCLONE INTO THE MIDDLE OF THE CONUS…IT APPEARS THE LEADING EDGE OF THIS AIR MASS SHOULD STRUGGLE TO ADVANCE MUCH SOUTH OF I-70 OVER KS/MO THIS WEEKEND. STRONG MID-LEVEL SPEED MAX IS FORECAST TO DIG SEWD INTO THE LOWER CO RIVER VALLEY SATURDAY WITH UPPER DIFLUENCE EXPECTED ACROSS THE PLAINS AS FAR SOUTH AS WEST TX AT 27/00Z.

THIS EVOLUTION WILL ALLOW SUBSTANTIAL MOISTURE TO ADVANCE POLEWARD ACROSS THE SRN PLAINS WHERE PW VALUES SHOULD EASILY APPROACH 1.25 INCHES AS SFC DEW POINTS CLIMB THROUGH THE MID-UPPER 60S ACROSS A BROAD WARM SECTOR. LATEST THINKING IS MODERATE-EXTREME INSTABILITY SHOULD DEVELOP ALONG ERN PLUME OF STEEP LAPSE RATES FROM WCNTRL TX…NWD INTO SCNTRL KS SATURDAY WHERE MUCAPE COULD APPROACH 4000 J/KG. IF THERMODYNAMIC ENVIRONMENT EVOLVES AS LATEST GUIDANCE SUGGESTS THEN POTENTIALLY SIGNIFICANT SUPERCELL DEVELOPMENT WITH VERY LARGE HAIL AND TORNADOES CAN BE EXPECTED.

CONVECTION SHOULD INITIATE ALONG DRYLINE FROM SWRN TX…NWD INTO WRN KS SATURDAY THEN REDEVELOP AGAIN SUNDAY FROM SERN KS…SWD INTO CNTRL TX AS MID-LEVEL SPEED MAX EJECTS INTO THE SRN PLAINS. SEVERE TSTMS SHOULD SPREAD INTO THE MS VALLEY BY EARLY MONDAY. ORGANIZED SEVERE MAY CONTINUE INTO THE DAY7 PERIOD BUT SUBSTANTIAL CONVECTION DURING THE DAY5-6 TIME FRAME COULD POTENTIALLY DISRUPT THERMODYNAMIC ENVIRONMENT…THUS CONFIDENCE IS NOT AS HIGH.

Think about what your plans will be in the aforementioned areas this weekend. Weather will change very quickly. Now is the time you want to go over your severe weather plan.

Severe Weather Threat Exists for Sunday in Oklahoma City (4-11-2014)

Severe weather is looking likely for most of Oklahoma on Sunday. In fact, a moderate risk for severe weather will exist in Oklahoma on Sunday. Areas east of US 281 and south of I40 looks like the best bet. Here tornadoes are possible as well as large damaging hail and straight line winds. North of this area and east of US 281, a tornado threat is next to zero, but there is still a slight chance of severe weather. Mainly the threat will be damaging winds and marginally severe hail up to golf ball sized.

I will have the latest information when it becomes available.
