Chase Day 1 Discussion - South Texas

[Paul Sherman]

Seems like an eternity but Chase Day 1 Proper is finally here and we are making an early Start today leaving in about 90 minutes heading South from DFW. Have a 280 Mile drive South for Stage 1 today to be in San Antonio for Lunch, will refine from there.

Hoping the Tornado Parameters remain favourable further towards the Coast, things that could scupper us would be groups of Storms / MCS's moving out of Northern Mexico, if we can get enough clearing for a few Supercells to Develop then we could be in the action later on today, might even be a bonus Lightning fest over the Gulf Of Mexico overnight as well.

Good luck guys, watch out for those banditos!

[Supercell 89]

Good luck amigos

[Nick F]

Yep, good luck with the trek down south - might even see a spout off the Gulf Coast - be a NW chase first?

[Paul Sherman]

13z SPC Update suggest Possible Upgrade to Moderate Risk for Tornadoes Later today with all modes of Severe Including Supercells and Huge MCS Later

New Ground for me as never chased South of San Antonio before

good luck!

[Arron]

Tornado Watch time!

THE NWS STORM PREDICTION CENTER HAS ISSUED A

TORNADO WATCH FOR PORTIONS OF

SOUTH-CENTRAL AND DEEP SOUTH TEXAS

COASTAL WATERS

EFFECTIVE THIS THURSDAY MORNING AND EVENING FROM 1140 AM UNTIL

800 PM CDT.

TORNADOES...HAIL TO 3 INCHES IN DIAMETER...THUNDERSTORM WIND

GUSTS TO 70 MPH...AND DANGEROUS LIGHTNING ARE POSSIBLE IN THESE

AREAS.

THE TORNADO WATCH AREA IS APPROXIMATELY ALONG AND 75 STATUTE

MILES EAST AND WEST OF A LINE FROM 55 MILES NORTHEAST OF COTULLA

TEXAS TO 25 MILES EAST SOUTHEAST OF MCALLEN TEXAS. FOR A

COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH OUTLINE

DISCUSSION...TSTMS /INCLUDING SUPERCELLS/ ARE ONGOING AS OF LATE

MORNING INVOF A STATIONARY BOUNDARY WHICH EXTENDS FROM N OF LRD TO

NEAR OR JUST S OF PSX. AIR MASS ALONG AND S OF THIS BAROCLINIC ZONE

IS QUITE MOIST WITH DEWPOINTS IN THE UPPER 60S-LOWER 70S. WHEN

COUPLED WITH DAYTIME HEATING AND STEEP MIDLEVEL LAPSE RATES...EXPECT

ENVIRONMENT TO BECOME MODERATE-STRONGLY UNSTABLE BY AFTERNOON WITH

MLCAPE APPROACHING 1500-3000 J/KG. THIS INSTABILITY WILL ALIGN WITH

A STEADILY STRENGTHENING DEEP-LAYER WIND FIELD /AND VERTICAL SHEAR/

OWING TO THE EWD-DEVELOPMENT OF MID AND UPPER-LEVEL JET STREAKS

ACROSS THE LOWER RIO GRANDE VALLEY. AS SUCH...SETUP IS EXPECTED TO

BECOME INCREASINGLY SUPPORTIVE OF INTENSE SUPERCELLS CAPABLE OF VERY

LARGE HAIL...TORNADOES...AND DAMAGING WINDS.

UPDATE (WOUS64 KWNS WOU1).

good luck, the main challenge will be viewing, with the amount of tropical moisture around. Sea breeze front inland from CC a likely final destination.

[Arron]

Massive hail in that one Ashley!

[Tom Lynch]

good luck team . lots to see out to your south west and west and south . I am pleased you are going to see some action.

Tom
