The Storm Prediction Center has issued a Severe Thunderstorm Watch until 8 PM. This watch includes western North Texas and the Hill Country. Throckmorton, Mineral Wells, Eastland, Brownwood, Eden, and San Saba are a few cities included in this watch. The strongest storms may produce hail up to the size of softballs and damaging winds over 60 MPH. The tornado threat is low, but a brief tornado cannot be ruled out. A strong cap will keep the number of storms down, but any storm that forms will likely be quite severe.

12:30 PM Severe Weather Analysis

The Storm Prediction Center has issued a standard risk of severe weather for western portions of North Texas and the Hill Country for later this afternoon. The outlook runs east of a Throckmorton, Clyde, Eden, and Junction line. The risk runs west of a Graham, Stephenville, Lampasas, and Llano line. Junction, Brady, San Saba, Brownwood, Eastland, Breckenridge, and Graham are a few cities included in the risk today. Let me go ahead and say this does not look like Wednesday at all. Wind shear is much weaker and a stronger cap will make it difficult for storms to develop. Even with weaker wind shear, the atmosphere is going to be extremely unstable. The lack of wind shear will be offset slightly by the extremely unstable airmass. That should allow for a few supercells to develop by late afternoon.
As the simulated image (below) from a high-resolution model shows, we only expect a few storms this afternoon. Any storm that is able to break the cap and develop will become severe rapidly. With an extremely unstable airmass in place, giant hail will be possible. While the wind shear is weak, we cannot rule out a brief tornado because of the extreme instability. That said, we do not see conditions favorable for strong to violent tornadoes. High cloud bases and marginal low level wind shear will keep the tornado threat low, but not zero. The severe weather threat will diminish a few hours after sunset as the cap becomes stronger and kills any storms that manage to develop this afternoon.
(This is a simulated radar image from a weather model. Do not expect storms to be where this graphic shows this afternoon simply because this graphic shows it.)
We’ll be here this afternoon to post updates, just as we did on Wednesday. For the latest updates, follow us on Facebook, Twitter, and Google+.

The National Weather Service now says 12 tornadoes touched down on Wednesday. Six people have are confirmed deceased and dozens are injured. Some remain missing out of Granbury. This post contains more details about each tornado. Additional information will be released later this evening and we’re working to compile a detailed event page with photos and radar data for each tornado. We’ll have a special Google+ Hangout session tonight at 9 PM to discuss yesterday’s outbreak. You’ll be able to watch this show live on YouTube.

Tornado Watch has been posted for much of North and Central Texas until 1 AM. This includes the D/FW Metroplex, Waco, and Temple. This replaces the Severe Thunderstorm Watch previously in effect for North Texas. One tornado has already been confirmed and I’m afraid the storms west of D/FW are in a prime position to bring big problems into D/FW in a few hours. This is turning into a serious situation. Very large hail up to softball size, tornadoes, and damaging wind are all possible.

The Storm Prediction Center has indicated that they may have to upgrade a portion of the Severe Thunderstorm Watch to a Tornado Watch shortly. This is due to increasingly favorable conditions for tornado development. A fairly large tornado has already occurred in Montague county and additional storms are forming from Mineral Wells south into the Hill Country. These storms may become severe shortly with a significant severe weather threat.
MESOSCALE DISCUSSION 0647 NWS STORM PREDICTION CENTER NORMAN OK 0540 PM CDT WED MAY 15 2013 AREAS AFFECTED...NORTHWEST/NORTH-CENTRAL/CENTRAL TX AND SOUTHERN OK CONCERNING...SEVERE THUNDERSTORM WATCH 160... VALID 152240Z - 152345Z THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 160 CONTINUES. SUMMARY...DAMAGING WIND/SEVERE HAIL POTENTIAL CONTINUES ACROSS SEVERE TSTM WATCH 160...WITH THE LARGEST HAIL POTENTIAL ACROSS PARTS OF NORTHWEST INTO NORTH-CENTRAL TX. SOME TORNADO POTENTIAL EXISTS AS WELL MAINLY ACROSS NORTH-CENTRAL INTO CENTRAL TX...MONITORING FOR A PARTIAL TORNADO WATCH UPGRADE. DISCUSSION...DISCUSSION PRIMARILY CONCERNS NORTH-CENTRAL TX...WHERE SOME TORNADO POTENTIAL WILL EXIST INTO THIS EVENING. SOUTH OF A CLUSTERING BAND OF STORMS ACROSS SOUTHWEST TX...CU FIELD CONTINUES TO DEEPEN WITH TSTM DEVELOPMENT IN VICINITY OF LOW-LEVEL CONFLUENT/DIFFERENTIAL HEATING AXIS THAT EXTENDS FROM EAST OF WICHITA FALLS SSW TO GRAHAM AND BROWNWOOD AREAS. STORMS MAY CONTINUE TO DEVELOP WITHIN THIS CORRIDOR AND SPREAD EAST-NORTHWARD TOWARD SOMEWHAT COOLER SIDE OF THE BOUNDARY. MODEST TEMPERATURE-DEWPOINT SPREADS AND MODERATELY STRONG LOW-LEVEL SHEAR ARE NOTED NEAR/EAST OF THE CONFLUENT AXIS...WITH A RECENT TREND OF BACKING LOW-LEVEL FLOW /SOUTHEASTERLY/ AND AS MUCH AS 150-175 M2/S2 OF 0-1 KM SRH PER MODIFIED FORT WORTH WSR-88D VWP. THIS SUPPORTS THE NOTION OF AT LEAST SOME TORNADO POTENTIAL INTO THIS EVENING...SUCH THAT A TORNADO WATCH MAY BE NEEDED SHORTLY.
