Strong tornadoes plowed through the Midwest U.S. last night and this morning, killing at least nine people. Six people died in Harrisburg, Illinois when a tornado hit near 5:37 am CST this morning, damaging or destroying 200 buildings. Another person was killed in southwest Missouri near Buffalo when a possible tornado ripped through a mobile home park. Thirteen others were injured in the mobile home park. Two others died in the Cassville and Puxico areas. A tornado also moved through downtown Branson, Missouri early this morning, causing heavy damage to the city's famous theaters, and injuring at least twelve people. A tornado plowed through the small town of Harveyville, Kansas (population 275), twenty miles southwest of Topeka, at 9:03 pm last night. The tornado destroyed 40 - 60% of the structures and injured ten, one critically. NOAA's Storm Prediction Center logged fifteen preliminary tornado reports yesterday and today.

The same storm system also brought the heaviest snows of the winter to portions of the Upper Midwest, which has received scant snowfall this winter. Blizzard warnings are posted in South Dakota this morning, where snowfall amounts of 6 - 10 inches are common. According to NOAA's latest storm summary, five states have experienced snowfall amounts of ten inches or more--Wisconsin, Minnesota, South Dakota, Michigan, and Nebraska. The highest snow amount as of 8 am CST was recorded at Tripoli, Wisconsin, where fourteen inches had fallen.


Figure 1. Radar image of the squall line that passed through Harrisburg, Illinois this morning, spawning a tornado that killed three people. The position of Harisburg is marked by a circle with a "+" symbol.


Figure 2. NOAA's Storm Prediction Center logged thirteen preliminary tornado reports yesterday.

More tornadoes likely today
The powerful late-winter storm system that spawned the deadly tornadoes will move eastwards, bringing snows of 5 - 10 inches to northern Wisconsin, northern Minnesota, Michigan's Upper Peninsula, and northern New England. The storm's cold front is triggering severe thunderstorms over much of Kentucky this morning, and these thunderstorms are expected to grow in severity and spawn more tornadoes this afternoon, once the heat of the day destabilizes the atmosphere. NOAA's Storm Prediction Center has posted tornado watches for portions of Arkansas, Missouri, Tennessee, Kentucky, and Ohio this morning, and has placed much of Tennessee and portions of surrounding states in their "Moderate Risk" area for severe weather today. Consult our Severe Weather Page and Interactive Tornado Page to follow today's severe weather.

Your missing the point. That cell had a large area of rotation when it passed south of Corbin. These big cells are the ones that produce these m0onster tornadoes i.e Joplin, Jarrel, Greensburg, Tuscaloosa, Smithville.

Your missing the point. A hail core has almost no indication weather a storm has a large tornado on the ground or not. Only way you can tell if a storm has a large tornado on the ground by radar is with velocity and hook echos. Even then your still not sure.

Large core hence larger area of rotation to support a bigger tornado which seems to have been the case on according to come of the news sources. CNN has non-stop coverage of this event right now while TWC keeps talking about snowfall amounts in the upper midwest with limited severe wx coverage. Same old crap with TWC.

That's definitely not true, they have been primarily severe weather all freaking day. They'll stop maybe a minute to talk about winter weather, but that's it. Don't bash them and accuse them when severe weather isn't the only thing that matters. Winter weather is dangerous too.

LOW-LEVEL MOISTURE IS RICHEST OVER SERN OH SWD INTO NERN KY AND
WV...WHERE THE GREATEST SVR THREAT IN THE NEAR-TERM WILL BE FOCUSED.
A STORM OCCASIONALLY EXHIBITING SUPERCELLULAR CHARACTERISTICS IS
CROSSING THE OH RIVER INTO WOOD COUNTY WV AND MAY BE SUSTAINED

LAPSE RATES AND LOW-LEVEL CONVERGENCE /ALBEIT WEAK/ IS RELATIVELY
MAXIMIZED. CONVERGENCE ALONG A PRE-FRONTAL SFC DRYLINE DRAPED NE-SW
FROM N-CNTRL TO SW OH ALONG WITH INCREASING DCVA IN ASSOCIATION WITH
AN APPROACHING IMPULSE FROM THE MID-MS VALLEY REGION MAY SUPPORT
DEEPENING OF CONVECTION DURING THE NEXT COUPLE OF HOURS. WHILE
CONFIDENCE IN STORM DEVELOPMENT THIS FAR NORTH IS NOT EXCEEDINGLY
HIGH...LATEST RUNS OF THE EXPERIMENTAL HRRR INDICATE SOME POTENTIAL
FOR DEEPER CONVECTION EVOLVING IN THIS REGION DURING THE NEXT COUPLE

From NWS Hastings, NE:

"A rare set up for thunderstorms and severe weather set up across the Central Plains region on Tuesday, February 28th, as an intense low pressure system emerged from the central Rockies and crossed the Central Plains. Ahead of the approaching system, warm and moist air was drawn north, and by afternoon dewpoints rose into the 50s across eastern into central and eastern Nebraska, and caused instability to increase (dewpoints this high are greater than our seasonal normal high temperatures in the mid 40s for this time of year). Strong to severe thunderstorms developed along frontal boundaries (dry line and cold front) by mid afternoon and the storms persisted into the early evening hours.

Although strong straight-line winds and small hail were the primary features with these storms, there have been TWO EF0 tornadoes confirmed within the NWS Hastings coverage area. These were the FIRST-EVER February Tornadoes with the strongest storm within the NWS Hastings coverage area crossing through portions of Jewell and Mitchell counties in north central Kansas, where damage occurred to outbuildings and a house, and power poles were snapped. Personnel from the Hastings, NWS office are currently in the process of conducting a storm damage survey in this area to determine if a tornado occurred, and the results of this survey will be posted as soon as possible.

In addition to the damage reported in north central KS, other damage reports have started trickling in as well from northern portions of the NWS Hastings coverag area. Some of these reports include:

- Brief EF0 tornado 4 miles west of Greeley, NE, around 7 PM on the 28th, which flipped on irrigation pivot
- Irrigation pipe tossed and a 3000 lb. grinder overturned by severe winds 1 mile east of North Loup around 649 PM on the 28th

There were also numerous reports of small hail (pea size) with these storms, and also some intense wind gusts, many of which occurred well after actual thunderstorms moved off to the east (see below for more details on these winds)."

I looked at a 3 hour radar, and seen that a very strong cell passed over some of my relatives up in southwest WV. looks like the southern part, the part looked ready for tornado production, went about 10mi south of them:)

They also have a creek winding in between their houses in the valley, and everytime a thunderstorm comes it rises about half a foot due to mountain run-off. Sometimes it floods:/

Quoting Xyrus2000:


The speed of hail depends on a number of factors. The maximum unimpeded unassisted speed of large hail is 105-125mph. Usually the speed is a bit lower as hail is rarely smooth and spherical and it is rarely unaffected by conditions.

Regardless, you don't want to be outside in a large hail storm unless you feel like getting repeatedly pelted by the equivalent of a professional baseball players fastball. :P



Hailstorms have caused only a handful of deaths in the United States over the last 100 years or so; most of those killed were children. We have reports of one child dying from a hailstone strike in 1893 and another in 1928. A Texas farmer perished on account of hail in 1930, and babies had their skulls broken by balls of ice in 1979 and 1981.

Hailstone deaths in other countries are somewhat more common. A few years ago, the Chinese government reported that at least seven people in Zhengzhou died in a storm of "egg-sized" hail. Dozens more ended up in the hospital. In Bangladesh, a giant storm of "grapefruit-sized" hail killed almost a hundred people in 1986. Some of the stones weighed more than 2 pounds.



http://www.slate.com/articles/news_and_politics/e xplainer/2006/04/how_dangerous_is_hail.html




In 1942 a British forest guard in Roopkund, India made an alarming discovery. Some 16,000 feet above sea level, at the bottom of a small valley, was a frozen lake absolutely full of skeletons. That summer, ice melt revealed even more skeletal remains, floating in the water and lying haphazardly around the lake's edges. Something horrible had happened here.

A National Geographic team set out to examine the bones in 2004. Besides dating the remains to around 850 AD, the team realized that everyone at the "Skeleton Lake" had died from blows to the head and shoulders caused by "blunt, round objects about the size of cricket balls."

This eventually led the team to one conclusion: In 850 AD this group of 200 some travelers was crossing this valley when they were caught in a sudden and severe hailstorm. An ancient folk song of the area describes a goddess so enraged at outsiders who defiled her mountain sanctuary that she rained death upon them with ice stones "as hard as iron."

Hail killed every last one of them.

The last known hail fatality in the US happened in 2000 in Fort Worth, Texas when 19 year old Juan Oseguera was hit in the head with softball sized hail. Hail of this size falls at around 100mph, and weighing as much as a pound, the force is the equivalent someone throwing a masonry brick at your head, which is more than enough force to kill you.

Quoting MississippiWx:
The storm on Friday/Saturday will develop and track through an area that would favor severe weather a little farther south and east across Arkansas, Northern LA/MS, Alabama, Tennessee and Georgia. The dynamics look pretty good, but the difference between the current storm and the storm upcoming is the storm this weekend will have a positive tilt as opposed to a negative tilt the current system has.

A negatively tilted system would have a much greater risk for significant severe weather due to the stronger dynamics and maturity of the low pressure. That's not to say the system won't produce severe weather. It most likely will produce some. However, it should not be as huge of an outbreak as it could be if the system were to take on a negative tilt.

Here's the 12z GFS forecast for the Friday/Saturday system:

There is a system a week or so out that has the same dynamics as this one with the exception that there should be more deep moisture available to it. Tis the season.

It's still going to be a significant one, probably greater than yesterday/today's if things pan out like many models think it will.


Remains to be seen if it will be worse, but it could be just as bad considering the risk areas will be closer to the actual area of low pressure Friday/Saturday.
