A significant multi-day severe weather event is expected Saturday, Sunday, and Monday across the Central U.S. A strong low pressure system will trundle slowly across the region, spawning supercell thunderstorms capable of generating large hail, damaging winds, and a few strong tornadoes. The action will begin Saturday afternoon along a swath from Central Texas northwards into Oklahoma and Kansas, then gradually shift eastwards on Sunday and Monday. Recent runs of the GFS and European model have been very consistent in showing moderate to extreme instability in the warm air ahead of the storm's cold front Saturday through Monday, and this weekend's severe weather outbreak has the potential to be the most dangerous one of this relatively quiet 2014. This year has yet to spawn a killer tornado, setting a new record for latest date of the year's first killer tornado. The previous record belonged to 2002, when the year's first killer tornado struck April 21 (an F-3 that killed a man in a mobile home in a rural area of Wayne County, Illinois.) The relatively cool and dry weather across Tornado Alley so far this year has led to no EF-3 or stronger tornadoes as of April 23, and that's also a record-long wait since modern tornado records began in 1950. According to tornado historian Tom Grazulis' book, Significant Tornadoes 1680-1991, "serious efforts" to document all tornadoes began in 1953, which was the first full year of tornado watches issued by the U.S. Weather Bureau, now the National Weather Service.

Yup , gonna get hectic around OK and KS this weekend , a friend of mine is flying over on Friday to chase.. id be on a plane with him if i didnt have exams coming up !

Moderate risk on the day 3 outlook (Sunday)

Day 3 convective outlook National Weather Service Storm Prediction Center Norman OK 0229 am CDT Friday Apr 25 2014

Valid 271200z - 28 100

..there is a MDT risk of severe thunderstorms for the arklatex area.

...There is a slight risk of severe thunderstorms from the MO valley to the western Gulf Coast...

... Outbreak of severe storms possible on Sunday across parts of the central states with large hail...damaging winds...and tornadoes. ... A vigorous shortwave trough expected to be centered in the Lee of the southern rockies at 12z/sun will substantially slow as it progresses towards Nebraska. An attendant middle-level jet /aoa 50 knots at 500 mb/ will persist from the desert SW...curling northward from the Red River to the MO valley. At the surface...a cyclone should drift eastward over the Central Plains with a warm front arcing eastward across the corn belt to the lower Ohio Valley. A dryline/weakening Pacific cold front should reach eastern Kansas/OK into deep S Texas in the late afternoon.

..MO valley to the western Gulf Coast... The warm sector will become increasingly broad/moist beneath an eml with lower 60s surface dew points becoming established near the warm front and middle to upper 60s into the lower/mid-MS valleys and arklatex by Sun afternoon. Initially steep middle-level lapse rates along with moderate to strong deep-layer shear will support an expansive area of organized severe potential. Areas of convection should be ongoing at 12z/sun across parts of the Southern Plains to middle-MO valley. Some of this activity may already be surface-based or will transition to becoming so as diurnal heating ensues. Clusters of isolated to scattered severe storms will be possible as convection likely develops N/E. The most probable severe risk should develop along and ahead of the dryline towards peak heating...with confidence greatest in this occurring near the southern periphery of early day storms /centered over the arklatex/. With robust heating occurring across Texas...

MLCAPE should push 2500 j/kg ahead of the dryline. Hodographs appear quite conducive to supercells...capable of producing very large hail and strong tornadoes. With the dryline stalling across northestern Texas sun evening...training supercell clusters may continue into the night. Along the dryline farther north into the MO valley...early day convection may tend to limit a greater severe risk. But with strong insolation...moderate buoyancy may develop within a steep lapse rate environment. Although deep-layer wind profiles should be largely meridional...sufficient curvature to the low-level hodograph would support updraft rotation...with all severe hazards possible.

Tornado Emergency has been issued for Joplin, Missouri. The same town that was hit by a devastating F5 in 2011.

Click up the top where it says "Live Storm Chasing" and then "Storm Chasers" and a menu will pop up. Usually watching the one with the most viewers is a good bet.

cool thanks!

Nearly 3 years to the day of which i was over there when Joplin got hit by a F5 tornado , lets hope this cell passes through quickly ... the news reports from that evening are still a vivid memory

Hammer Archer

Going by the Doppler, it looks as though Joplin may have been spared this time. The southernmost cell of the three seems to have just gone to its south while the middle cell brushed by to the north.

Out of interest Ian, what software are you using?

Yeah luckily it looks to have slid passed by any big town so far.


Its a premium programme called GR level 3. One of the main feeds of hardcore data for chasers out in the states.

You could give them all the money in the world but unfortunately it wouldn't do anything to improve our weather.

It's important to have detailed local weather in that part of the world because of the high occurrence of these very powerful but very localised storms. Having detailed forecasts, good radar coverage and frequent updates can mean life or death in these places. It's just unfortunate that even with warnings, some of these storms can be so violent that anything above ground level will be leveled and not everyone has a basement to seek shelter, mobile homes etc.

Iancar29

Yep , no need for phased array radars over here .

I really dislike the fact that over that the majority of the houses in tornado alley are wooden built . If i lived in tornado alley with a wooden structure id at least fork out the money for a tornado shelter.

Another day of strong storms today possible.

Re house build, it made no difference last night when several of the properties were brick built. I obviously don't know the details, but one can build a stranger wooden house than in brick unless reinforced.

The wooden houses are not as poor a choice as one might initially imagine, they are all prefabricated and can be assembled in the shortest time frame to at least minimise the homelessness.

It was good to see that a neighborhood that was destroyed three years ago has had a safe room built inside their elementary school now and some 200 people took refuge there and were safe edit < Last Night [27th].

They are trying to encourage people to rebuild with a saferoom core as they rebuild their homes, relatively inexpensive at that stage, some have and survived, many still won't.

Simon Gruber Says

Even the best built homes can be completely destroyed in a very powerful tornado. It's not just the wind they have to withstand, it's all the debris that's picked up and being slammed into everything, in a sense it becomes a giant blender. Cars and heavy machinery will destroy anything they hit if tossed. The only safe place is underground.

I'm surprised houses in high occurrence area can get insurance, I have no idea if they can.

for noobies , left image is general reflectivity and the right image is relative velocity so shows where rain is moving towards and away from the radar . This indicates rotation.

Any warnings in effect right now in america?

Hammer Archer

Not now.
You can see the warnings from the NWS here:
http://www.weather.gov/
Tornado warnings (i.e. usually meaning a tornado on the ground, dropping or a storm capable of producing one) show up in red on the map.
Tornado Warning also shows up in the legend below the map when there's one active.

Hammer Archer

Scratch that. Tornado touchdown in North Carolina.

Accuweather predicting more severe weather tomorrow night. A low pressure is moving over the Rockies while the cental plains are getting record heat.

They are not ruling out the possiblilty of Tornados but say the plains are more likely to see straight line winds.

Maybe an expert can explain here but if the warm moist winds from the Gulf are South Eastern, and the dry warm winds from New Mexico are to the South West along with a South Western Jet at upper level, wouldn't that create the rotation necessary for tornados to develop?

Not wishing to hijack the thread but I'm off to Oklahoma City on Sun. May 18th for a storm-chase tour with http://www.silverliningtours.com/

Just wondering if anyone here on Weather forum might be going?

Not going myself but know of the their group , met them whilst over with a different tour group before. Enjoy it though man , may the troughs be ample and the ur storms rotate


Heres something you possibly could get to see...

Storm just near Wichita Texas , yesterday , photo taken by a mate of mine Paul Bolten.

Was worth staying up till 1am watching the radar data , saw the storm grow from noting into a right moving supercell with a tornado warning on it for a short time!
