There is a slight risk of severe weather for most of Oklahoma this morning through late tonight.
Large hail and damaging winds will be the primary threats.

Here is the SPC Severe Weather Risk Map for today.


After tonight, look for a hot and humid summer like weekend!

Large damaging tornado’s are on the ground near Stillwater, Moore, Norman and other cities west of Tulsa.

 

Please tune into your local media and make emergency perpetrations now.

A Particularly Dangerous Situation Tornado Watch will likely be issued for all of Eastern Oklahoma. Large violent tornado's have occured west of and near OKC and these storms as heading our way.






A HIGH risk of severe weather remains in place for most of Oklahoma.
Locally heavy rain, damaging winds, hail to the size softballs, tornado's, and strong long track tornado's are possible in this area.



Hail potential tonight is off the charts with 4-5 inch diameter hail possible in the strongest storms.

Here is the Tulsa NWS hail size potential graphic.

More than one round of storms is likely this evening. Please stayed tuned to the local media for any possible warnings. For the ride home, 102.3 KRMG is your best bet.

Storms are expected to begin forming in the next hour west of Oklahoma City.
A Particularly Dangerous Situation Tornado Watch has been issued for areas west of Tulsa.
This will expand to cover all of eastern Oklahoma late this afternoon.
 
This will expand to cover all of eastern Oklahoma late this afternoon with storms nearing the Tulsa area by 7:00 PM.



A very small tornado can rapidly become a monster so please take all watches and warnings seriously. The Joplin tornado went from a small single funnel to a 1/2 mile wide wedge in less than a minute and a half based on some chaser video that has been released. Again, in this environment today, take all watches and warnings seriously.


Here is the SPC risk map indicating that most of Oklahoma is under a HIGH risk of SIGNIFICANT severe weather. The high risk area has been expanded eastward since this mornings update.




The Tulsa NWS released the public statement below.

...LONG TRACK VIOLENT TORNADOES POSSIBLE LATER TODAY...

An outbreak of severe thunderstorms is expected across portions of eastern oklahoma and northwest arkansas later today. The potential

For high impact severe weather...including violent long-track tornadoes...is high.

Residents across the region should monitor this situation very closely. Watches and warnings will likely be issued

Later today. Have a tornado safety plan in place before severe weather develops and warnings are issued. Stay in close contact with

Family members and be prepared to take quick action if and when a tornado warning is issued for your area. Persons living in mobile

Homes should consider staying with family or friends that have a more substantial shelter...such as a basement or safe room. Persons

May want to consider postponing outdoor activities that are not absolutely necessary late this afternoon and evening or at

The very least be prepared to move to a designated shelter location quickly. 

All of the ingredients appear to be coming together for a significant and dangerous severe weather outbreak across a good portion of Central and Eastern Oklahoma.

The current HIGH risk area includes both the Tulsa and Oklahoma City metro areas.


Here is the current SPC risk graphic:




Damaging winds, hail to the size of softballs, tornado's, and strong long track tornado's are possible in the high risk area.

Here is a Tulsa NWS graphic indicating the expected timing of the storms. Currently it appears the Tulsa area will be affected after 7:00PM at which time some models indicate the atmosphere will be most supportive of strong tornado's.



There will likely be multiple updates to the forecasts as all weather services are working hard to refine the forecasts as new data comes in.

There is the potential for this to be an extremely dangerous evening.

Here is a Public Information Statement Issued by the NWS this morning indicating the potential danger this evening.

Review of severe weather safety rules...

An outbreak of severe thunderstorms is expected across portions of

Eastern Oklahoma and northwest Arkansas later today. The potential

For high impact severe weather...including strong long-track

Tornadoes...is high. Residents across the region should monitor

This situation very closely. Watches and warnings will likely be

Issued later today. Have a tornado safety plan in place before

Severe weather develops later today. Stay in close contact with

Family members and be prepared to take quick action if and when a

Tornado warning is issued for your area. Here are some safety

Rules to keep in mind when severe weather is expected or is

Occurring.

Before severe weather strikes...ensure that you and your family

Are fully prepared. In a home or building have a pre-designated

Shelter... Such as a basement or an interior room or hallway.

Have on hand a disaster supply kit...including a NOAA weather

Radio...flashlight...radio and a good supply of batteries.

If a severe thunderstorm or tornado warning is issued...seek shelter

Indoors immediately. A severe thunderstorm is defined as producing

Quarter size or greater hail and wind gusts of 58 mph or more. In

Extreme cases...severe thunderstorms can produce winds to near 150

Mph and hail larger than grapefruits, which can cause extensive

Property damage.

Tornadoes often form very rapidly from severe thunderstorms. If

You are in a tornado watch...and a severe thunderstorm warning is

Issued for your area...monitor local conditions closely and be

Ready to take quick action to save your life.

Remember that lightning is a thunderstorms most underrated killer.

Postpone outdoor activities if thunderstorms are imminent. This

Is the best way to avoid being caught in a dangerous situation.

Automobiles offer good protection from lightning...although moving

Indoors is best. Even inside...lighting can kill by coming through

The phone lines...plumbing and electric lines. Therefore do not

Use computers...telephones or other hand held appliances during a

Storm.

 

The overall threat of severe weather has decreased this evening although some severe weather will likely still occur.

Here is the latest SPC risk graphic for this evening:



A significant outbreak of severe weather remains likely starting late Tuesday afternoon.

Previous update below….



The risk of severe weather remains this afternoon and evening with an enhanced tornado threat across the Tulsa area.
All modes of severe weather are expected tonight.


Here is the latest Tulsa NWS threat map for this afternoon:







A more significant severe weather event is expected on Tuesday.




Please take the time this to review your families and your businesses tornado safety procedures.


Here are some general safety guidelines:

Tornado Safety Rules

·               In a home or building, move to a pre-designated shelter, such as a basement.

·               If an underground shelter is not available, move to a small interior room or hallway on the lowest floor and get under a sturdy piece of furniture. Put as many walls as possible

·               between you and the outside.

·               Stay away from windows.

·               Get out of automobiles.

·               Do not try to outrun a tornado in your car; instead, leave it

·               immediately for safe shelter.

·               If caught outside or in a vehicle, lie flat in a nearby ditch or depression and cover your head with your hands.

·               Be aware of flying debris. Flying debris from tornadoes causes most fatalities and injuries.

·               Mobile homes, even if tied down, offer little protection from tornadoes. You should leave a mobile home and go to the lowest floor of a sturdy nearby building or a storm shelter.

There is a moderate risk of severe weather across most of Oklahoma this afternoon and evening.

Here is the SPC risk map for today:


The severe storms affecting the area this morning are expected to leave boundaries across the area that will interact with severe storms that form late this afternoon. The areas around these boundaries can expect an enhanced threat of severe weather late this afternoon.

Flash flooding, very large hail, damaging winds, and tornado's are likely late this afternoon and evening.

Here is a NWS graphic indicating the threats for this afternoon:






A MAJOR severe weather outbreak is expected across the area on Tuesday with  flash flooding, damaging winds, hail to the size baseballs, and large, long lived violent tornado's.

There is a moderate risk of severe weather for all of NE Oklahoma this afternoon and evening. Large hail, damaging winds, tornados, and even the possibility for strong tornado's.

Storms are expected to fire west of Tulsa late this afternoon and track across the area. There is a possibility that storms do not form but at this point it appears that they will and if they do, they will become severe.


Here is the SPC severe weather risk map for today:

Due in part to the rain and clouds sticking around longer than expected, the threat of severe weather in the Tulsa area has diminished for this evening.

There remains a slight risk west of Tulsa and ESE of Tulsa with large hail, damaging winds, heavy rain, and an isolated tornado in those areas. Thunderstorms remain possible in Tulsa this evening but they should mostly remain below severe limits.

A Flash Flood Watch remains in effect for areas east of Tulsa and a Tornado Watch is in effect for SE and far eastern Oklahoma this evening.


Here is the SPC's severe weather risk areas for this evening

FLASH FLOOD WATCH IN EFFECT THROUGH SATURDAY MORNING...

THE NATIONAL WEATHER SERVICE IN TULSA HAS ISSUED A

STAY AWAY FROM DRAINAGE DITCHES...CREEKS AND OTHER LOW LYING
AREAS.  THEY ARE PRONE TO RAPID RISES AND MAY FLOOD QUICKLY.

The storms this morning should move east of Tulsa by early afternoon. Another round of storms is expected late this afternoon and evening. The severity of these storms depends on how much clearing occurs in the area.

If skies clear this afternoon, the atmosphere will become unstable enough for very large hail, damaging winds, locally heavy rain, and possibly an isolated tornado.
If clearing does not occur, then large hail, damaging winds, and locally heavy rain remain a possibility.

Here is an NWS graphic indicating the expected weather today:


Updates to follow as necessary.

A round of storms is expected to be in the area Friday morning but should mostly stay under severe limits. Friday afternoon should bring a break in precipitation and allow the atmosphere to destabilize ahead of a line of storms expected late tomorrow afternoon and evening. This line of storms will likely be severe with large hail, damaging winds, and locally heavy rain possible.
There is a chance of an isolated tornado as well.

More updates in the morning...

Severe Thunderstorm Watch Issued until 10:00 pm for the areas shaded below.






There is a severe thunderstorm warning for Creek county at this time. This storm is moving NE and will likely effect parts of southern Tulsa county in the next hour or so.

There is a slight of risk of severe across most of Eastern Oklahoma with the greatest threat east of highway 169. Large hail, damaging winds, and an isolated tornado are possible with these storms.

Storms should begin to form around to just west of Tulsa between 4-6PM. These storms will likely remain below severe limits until they get east of Tulsa.

Here is the SPC Severe Weather Risk Graphic:



There could be some lingering showers in the area on Friday but they should remain light.

Much cooler weather on tap Friday through Monday with highs in 60's and lows in
 the 40's.

Here is a quick update to the severe thunderstorm potential.

Severe thunderstorms are on-going across all of central Oklahoma at this time. This line of storms is expected to continue to move to the NE with the storms SW of Tulsa expected to begin affecting our area as early as 4:30pm.

Here is the latest radar image:



 
Hail to the size of golfballs and damaging winds could occur in the strongest storms.


A severe thunderstorm watch remains in affect for the area through 7:00PM this evening.


Here is the current watch area (in yellow) and I would not be surprised to see the watch extended for a few hours this evening for the Tulsa area and expanded east into Arkansas as well:





Here is the latest SPC severe weather risk map for our area:

A line of storms currently entering the I-35 corridor in central Oklahoma are expected to intensify as they continue eastward. These storms could produce large hail and damaging winds but the tornadic threat is very, very low.

The cloud cover and wind fields ahead of this line of storms has limited the overall severe threat. After this round, the atmosphere is expected to be slow destabilize again thus the tornadic and overall severe threat across NE Oklahoma for today and tonight has been minimized.

Thursday may still bring a round of severe storms, including tornados.

Here is the watch area:




STRONG TO SEVERE THUNDERSTORMS WILL MOVE INTO EASTERN OKLAHOMA
EARLY THIS AFTERNOON...AND CONTINUE EASTWARD INTO NORTHWEST
ARKANSAS BY EARLY EVENING.  CURRENTLY...INSTABILITY IS HIGH
ACROSS THE REGION HOWEVER WIND SHEAR IS LACKING.  THIS WILL
PROMOTE ISOLATED CORES OF LARGE HAIL AND STRONG WINDS.  LATER
THIS EVENING...STORMS SPREADING NORTHWARD FROM CENTRAL TEXAS
MAY ENCOUNTER STRONGER WIND FIELDS TO SUPPORT A LIMITED TORNADIC
RISK FOR SOUTHEAST OKLAHOMA.  ADDITIONALLY...PERIODS OF HEAVY
RAIN WILL ACCOMPANY THE STORMS AS THEY TRACK EASTWARD THROUGH
THE AREA WITH RAINFALL AMOUNTS OF ONE HALF TO ONE INCH LIKELY.

There is the possibility of multiple rounds of severe weather across NE Oklahoma starting as early as this afternoon, this evening, and possibly again mostly for areas east of Tulsa late Thursday afternoon/evening

Large hail, damaging winds, and tornados are possible during the next 36 hours.

The exact timing of each round is tough to determine but weather watches, likely tornado watches, will be issued for the areas most at risk before any of the storms become tornadic.

The SPC forecast currently shows the greatest threat of severe weather today across north central Oklahoma while the Tulsa NWS pulls that area east to roughly highway 69.

Here is the NWS Graphic of the highest risk area:




Here is an image from simulated radar at 2:00PM today showing the possibility of severe storms in the area.




This is a complex situation that the models do not have a good feel for and is allowing for a lot of uncertainty. I will send out updates as the details become clearer and/or as weather watches are issued by the SPC.

Thunderstorms are forming South and West of Tulsa this afternoon and could impact the Tulsa area. These storms are expected to mostly remain below severe limits but could pulse up briefly and create some small hail.

Here is the latest radar image:




On Wednesday, storms are expected to form along the dryline in Western Oklahoma and track in Eastern Oklahoma during the early evening hours. Large hail, damaging winds, and an isolated tornado are possible with these storms.

Thursday, a line of storms is expected to form and sweep across the area with large hail and damaging winds being the primary threat.

Here is the latest SPC risk map for Wednesday:



Updates to follow...

There is a chance of severe weather on Wednesday and Thursday for Eastern Oklahoma. Large hail, damaging winds, and isolated tornados are possible during this timeframe.

Here is the Storm Prediction Centers severe weather risk map for Wednesday:



The greatest chances for severe weather across Eastern Oklahoma will be Wednesday afternoon through early Thursday.

Further updates with more specifics will be sent out as more data becomes available.
