***Significant Severe Weather Outbreak Expected***
Please verify your plans for taking cover NOW so when the times comes, you  can easily get into a safe place.

Storms are expected to form west of Tulsa and move into NE OK this afternoon between 3 and 4pm.
These storms will very rapidly become severe supercells that will be capable of producing hail to the size of baseballs and large, long track tornados, and heavy rain.

These storms will eventually form a line of storms which typically dramatically reduces the tornado threat. Tonight, tornados, hail to the size of baseballs, wind gusts to 70 MPH and widespread rainfall of 3-5 inches.

This threat will continue after dark so please ensure you have a way to get NWS weather alerts if you go to bed or are watching a movie not on Cox cable.

The Storm Prediction Center is expected to upgrade parts of the moderate risk area shown below to a high risk area with their 3:00 update.
webassets/May31SPC1.JPG


The tornado risk noted below is expected to increase as well.
webassets/May31SPC1.JPG



As is the hail threat:
webassets/May31SPCHail.JPG


A tornado watch should be issued shortly for far NE OK within the hour for storms forming further north.

Updates to follow....
Fri, May 31, 2013 | link

Severe Weather and Flooding Expected Today and Tonight
Hail to the size of baseballs, tornados, even large tornadoes, and very heavy rain are all expected today and tonight.

As storms begin forming this afternoon between 3:00 and 5:00, all modes of severe weather will be possible. Right now is appears storms will begin to fire just NW of Tulsa and in south central OK. As the line develops and fills in into the evening, heavy rain and large hail become the primary threats. Hail to 3.5 inches in diameter and widespread 2-4 rains are expected.

Most rain and storms should end in the Tulsa are be very early morning.

Here is the NWS risk map for today:

Severe Weather Expected This Afternoon and Evening

Storms are expected to fire off the dryline west of Tulsa and track east. Large hail, damaging winds, and possibly a tornado are possible in eastern OK. The severity of the storms will depend on many factors including how much dewpoints can increase, how much heating can take place, and where the boundaries from last nights and this mornings storms are. Please stay tuned to the NWS, local media, and this blog for updates.

Here is the NWS risk graphic for today:
webassets/May30NWSSvr.JPG

Friday brings yet another chance of severe storms and also a chance of very heavy rain which, with last nights rain and any rain that falls today will likely result in flooding. A flash Flood Watch will likely be issued at some point in the next 24 hours for the Friday storms.

Severe Storms Remain Possible This Evening
As the newer model runs come in, it is looking more likely that thunderstorms will impact the area this evening, mainly after 6:00pm.

The severe threat should be large hail and damaging winds with an isolated tornado possible mainly west of highway 75. The overall threat with the line of storms will decline as they move east.

Thursday afternoon has the potential to be very stormy with damaging winds, very large hail to the size of baseballs, and tornado's, some possibly large so stay tuned...
Wed, May 29, 2013 | link

Severe Weather Possible Tonight
There is a risk of severe weather tonight across NE OK, mainly after 6:00PM. Large hail, damaging winds, and possibly a tornado are possible. The largest severe threat is mainly along and west of I35 where an SPC Moderate Risk Area exists. The storms are expected to weaken as they move east into the late evening or overnight hours but another complex is shown developing to the SW of Tulsa and moving into the Tulsa area by 6:00. This will need to be watched to see if it forms and how well it establishes its self if it does.

Thursday currently is listed as a Slight Risk day by the SPC but the ingredients for a possible significant severe weather outbreak could be in place across NE Oklahoma. This will need to be watched carefully and a higher risk could be placed on NE OK by the SPC for Thursday by late tonight.

Here are the Tulsa NWS risk maps for today and tomorrow and further updates will be posted today.
webassets/May29NWSSvr1.JPG


Below is Thursday's graphic. The positioning of the outflow boundary just north of Tulsa is one factor in where the most severe weather will occur and how severe it is.

Freeze Warning and Winter Weather Advisory Issued
WINTER WEATHER ADVISORY IN EFFECT FROM 1 AM TO 1 PM CDT FRIDAY...

THE NATIONAL WEATHER SERVICE IN TULSA HAS ISSUED A WINTER WEATHER
ADVISORY FOR SNOW AND SLEET...WHICH IS IN EFFECT FROM 1 AM TO 1
PM CDT FRIDAY...

FOR THE FOLLOWING COUNTIES...
* IN OKLAHOMA...OTTAWA AND DELAWARE. IN ARKANSAS...BENTON...
   WASHINGTON...CARROLL AND MADISON.

HAZARDOUS WEATHER...
* RAIN WILL MIX WITH OR CHANGE OVER TO SNOW THIS EVENING AND
   TONIGHT ACROSS NORTHEAST OKLAHOMA AND NORTHWEST ARKANSAS AS AN
   UNSEASONABLY COLD UPPER LOW DEEPENS OVER THE AREA. THIS SHOULD
   ALLOW TEMPERATURES TO COOL OFF ENOUGH THROUGH THE EVENING FOR
   SNOW TO DEVELOP WITHIN HEAVIER BANDS OF PRECIPITATION.

* LOCAL SNOW ACCUMULATIONS 1 TO 2 INCHES ARE POSSIBLE TONIGHT.
   MOST IF NOT ALL ACCUMULATIONS WILL BE CONFINED TO GRASSY AND
   ELEVATED SURFACES. IT IS ALSO LIKELY THAT ACCUMULATIONS WILL
   VARY CONSIDERABLY OVER RELATIVELY SHORT DISTANCES.

IMPACTS...
* ACCUMULATING SNOW ON TREES THAT HAVE LEAFED OUT COULD BE ENOUGH
   TO CAUSE LIMBS TO BE BROUGHT DOWN BY THE WEIGHT OF THE SNOW.
   THIS CAN POTENTIALLY CAUSE POWER OUTAGES IN A FEW AREAS. A FEW
   BRIDGES OR OVERPASSES MAY BECOME SLICK DURING HEAVIER PERIODS
   OF SNOW...ESPECIALLY AT HIGHER ELEVATIONS IN NORTHWEST
   ARKANSAS.

DEFINITION...
* A WINTER WEATHER ADVISORY MEANS THAT WINTERY PRECIPITATION MAY
   ACCUMULATE ON ROADWAYS.

PRECAUTIONARY/PREPAREDNESS ACTIONS...
* USE EXTRA CAUTION IF DRIVING.

Special Weather Statement from the NWS Concerning Snow Potential
AN UNPRECEDENTED LATE SEASON SNOWFALL IS FORECAST FOR
NORTHEAST OKLAHOMA AND POSSIBLY NORTHWEST ARKANSAS LATE THURSDAY
INTO FRIDAY...

AN UNSEASONABLY STRONG COLD FRONT...CURRENTLY LOCATED FROM NORTH-
CENTRAL TO SOUTHWEST OKLAHOMA WILL SWEEP SOUTHEAST ACROSS THE
REGION TONIGHT INTO THURSDAY MORNING. MUCH COLDER AIR WILL FILTER
INTO THE REGION BEHIND THE FRONT...WITH TEMPERATURES FALLING BACK
INTO THE 40S AND EVEN 30S BY THE END OF THE DAY THURSDAY IN SOME
AREAS. THE MAIN UPPER TROUGH WILL LAG BEHIND THE ADVANCING
FRONT...WHICH WILL PROVIDE LIFT TO PRODUCE PRECIPITATION BACK IN
THE COLD AIR BEHIND THE FRONT. THE LATEST DATA SUGGESTS THAT NEAR
SURFACE TEMPS WILL GET COLD ENOUGH TO ALLOW FOR THE PRECIP TO MIX
WITH OR CHANGE OVER TO SNOW IN NORTHEAST OKLAHOMA BY LATE IN THE
DAY ON THURSDAY AND POSSIBLY EVEN INTO NORTHWEST ARKANSAS BY LATE
THURSDAY NIGHT. IF THIS CHANGE OVER DOES INDEED OCCUR...THE SNOW
COULD BE HEAVY AT TIMES THURSDAY NIGHT INTO FRIDAY MORNING WITH
SOME LIGHT ACCUMULATION OF UP TO AN INCH POSSIBLE MAINLY ON GRASSY
OR ELEVATED SURFACES NORTH OF HIGHWAY 412. ANOTHER CONCERN IS THAT
SNOW COULD ACCUMULATE ON FULLY LEAFED TREES...WHICH...COMBINED
WITH THE STRONG NORTH WINDS BEHIND THE FRONT...COULD CAUSE LIMBS
TO BREAK. THIS IN TURN COULD LEAD TO POWER OUTAGES WHERE THE SNOW
IS THE HEAVIEST. ROADWAYS WILL LIKELY REMAIN WET DUE TO THE WARM
ROAD TEMPERATURES...BUT COULD TEMPORARILY BECOME SLUSHY IF THE
SNOW FALLS HEAVY ENOUGH.

STAY TUNED TO THE LATEST FORECASTS AND STATEMENTS AS THIS
EXTREMELY RARE EVENT UNFOLDS.
