Violent tornado rakes Tennessee

Tornadoes and severe thunderstorms ripped through Missouri, Arkansas, Illinois, Ohio, Tennessee, and surrounding states Sunday, killing at least 23 people. Hardest hit was northwest Tennessee, where tornadoes claimed at least 12 lives in Dyer County. Damage reports indicated that many houses in the tornado's path were completely destroyed leaving only the foundation, making it likely that the Dyer County tornado will be ranked as a violent F4 tornado (207-260 mph winds) on the Fujita scale. This would be the second F4 tornado of the year--an F4 tornado struck Monroe City, MO on March 13, as part of an 84-tornado assault on the Midwest that also featured 11 strong F3 tornadoes. There is a slight possibility that last night's Dyer County tornado was an F5--the most violent type of tornado, capable of incredible damage--but we won't know until the National Weather Service has a chance to get out today in daylight and perform a damage survey. The U.S. has not had an F5 tornado since the infamous Moore, Oklahoma tornado of 1999, which had the highest winds ever recorded in a tornado, 301 mph. The U.S. has already equalled last year total of F4 tornadoes (one), and this Spring's severe weather season is shaping up to be far more deadly and destructive than last year's unusually quiet one.


Figure 1. Damage reports for the 24 hours ending at 9am EST April 3 show the wide scope of yesterday's severe weather.

The threat for severe weather continues today. The "Moderate Risk" area in the latest outlook by the Storm Predisction Center covers a region unused to seeing tornadoes--coastal areas of North Carolina, Virginia, and Maryland. A strong cold front will push across the region this afternoon, creating a squall line with embedded supercells likely to produce tornadoes, damaging straight-line thunderstorm winds, and hail golf ball size and larger. The severe weather episode will end tonight as the cold front pushes off the coast and more tranquil weather returns to the U.S.

Tomorrow: An update on the severe weather outbreak, plus a look at Dr. Bill Gray's new forecast for the hurricane season of 2006.

copied from your link~ Mount Waialeale has racked up 116.25" in the past 30 days.

The tourism hasn't stopped in Hawaii. That's Disney (Parent owner of accuweather chasing customers to Fl). Notice too, accuweather predicted it wouldn't let up this week & finally has.

Dr. Gray's team has posted the April 4th update :) It doesn't seem as if there has been much change, if any, to the inital December forecast. Still looks like an active one.

April 4th Update

Have a great day guys!

Does anyone remember the Super outbreak of tornadoes that occured EXACTLY 32 years ago? I thought about this when those tornadoes hit this time.

Hawaii Residents See Sun After More Than 40 Days Of Rain
hightlights~

Nearly 92 inches of rain were recorded during March at Mount Waialeale, which is considered the rainiest spot on the planet. The previous record was about 90 inches in April 1971, according to the National Weather Service. & none too soon.

Kahala Mall closed and was evacuated shortly before 1 p.m. Friday because of ankle-deep water in the shopping center. Water also cascaded down stairways into the mall's warehouse, one floor down from the ground level. Store clerks barely had time to move their merchandise to higher ground.

Roundtop Drive, which already had been the scene of several mudslides, saw several major slides Friday. Cars were buried under one slide, which also undermined the roadway, KITV reported.

Doesn't look like todays damage will be near anything like yesterdays Link. No tornado reports, 102 hail reports~ nothing over golf ball size & 52 wind reports. As far as wind damage~ 2 homes lost a roof, the rest is tree damage. No injurys reported:)

I noticed that the cold waters off the east coast are quite similar but that the caribbean and gulf temps are kinda reversed. Last year at this time the gulf was normal and the caribbean was warm, now we have a warm gulf and a normal caribbean. I wonder if climatology has predictions for things like that?

Yeah the SST anomily from last year matches this year pretty well, save the Gulf is hotter. If the gif isn't animated hit refresh, it stops once it goes through a few times. The start is March 20, 2005. Ending on March 19, 2006. Can get a decient comparasion as it starts over again. It really shows the birth of La Nina.

Hey take a look at this. The low level circulation centers cyclone was talking about north of Puerto Rico are trying to fire up a little convection. Link

That 82 mph gust was probably measured close to the ground. It is likely that the upper floors would have experienced a higher gust than what would be observed at ground level.

During the severe storm we had last year that knocked out the power, water started pouring into our basement. We have 2 sump pumps down there, but because we had no power the water got to about an inch deep.

So 80 mph took out the walls of that building!
Good ole American 'smoke and mirrors' downtown construction, financed on 100 year city bonds.

To give an idea of how insignificant the storm was at my location, we moved to Plainfield just over a year ago, and already we have lost power 3 times (2 of those due to storms, and of the 2 storms only 1 was actually severe).
84. louastu
3. huhtikuuta 2006 klo 21:20 (GMT)
We didn't really get anything here. We had a tornado warning, but all that happened here was a downpour that lasted about 2 minutes, winds gusting to 30 mph, and some flashes of lightning.

Just a few miles North, in Avon, there was at least 1 large tree reported down. Mooresville, Brownsburg, and Elwood had 60+ mph wind gusts. And Indianapolis had an 82 mph wind gust.

yeah I drove along the south side of downtown on 70 JUST after the storm passed. Looked north and could see water shooting from the west side of the building near the top. apparently (according to the radio guy) it was a busted sprinkler line or something like that. A really eerie sight.

Ya, I have seen it. I live in Plainfield Indiana, which is about 15 miles away from Downtown Indianapolis. It is the third tallest building in Indiana at 36 stories. It apparently got hit by wind gusts in excess of 80 mph.

Anyone see the pictures of the damage in downtown indy? They still don't know if it was a tornado or not, but the uppar part of one of the biggest buildings in Indy had glass blown out and some damage done inside the building.

Alright, just making sure. They're pretty scrawny though. There would need to be a real good fire up in convection if a good low level center wants to get going.

That mid-upper level feature in the middle Atlantic has quite a bit of spin. Looks like its at the tail end of a trough, might break away, but shear will probably be too high for anything to happen.

Are you seeing actual closed off low level circulations? Or just disturbances?

I am not sure how many people actually lost power in Indiana last night, but I know that when I said 5,200 my information was outdated. During the morning rush hour there were around 38,000 customers still without power.

Unfortunately I have not heard any reports since around 5:00 AM local time.
