The Interceptor meets the Dominator!

It was bound to happen one of these days!
Discovery Channel's Reed Timmer (Storm Chasers) poses with Discovery Channel's (Is that weird or what?) Steve Douglass.

We talked about fifteen about tonight's chase, tornados (what else) and even Area 51!








Joel and the other Tornadovideos.net team watch the storm:

Tornado watch likely




SEVERE RISK IS EXPECTED TO INCREASE THROUGH LATE AFTERNOON/EARLY
EVENING ACROSS PORTIONS OF SOUTHEAST CO/NORTHEAST NM AND THE WESTERN
OK PANHANDLE AND PORTIONS OF THE TX PANHANDLE/TX SOUTH PLAINS. ONE
OR MORE WATCHES MAY BE NEEDED BY 22Z.

MDT/TOWERING CU CONTINUES TO BECOME MORE PREVALENT AT MID AFTERNOON
ACROSS FAR SOUTHEAST CO AND NORTHEAST NM IN OROGRAPHICALLY
FAVORED/FOOTHILL AREAS...WITH ADDITIONAL CUMULIFORM DEVELOPMENT
INCREASING WITHIN A WARM/DEEPLY MIXED BOUNDARY LAYER ALONG THE
EASTERN NM/TX SOUTH PLAINS BORDER VICINITY. FARTHER EAST...STRATUS
FIELD CONTINUES TO ERODE ALONG AND NORTHEAST OF AN EFFECTIVE WARM
FRONT ARCING GENERALLY NW-SE FROM FAR SOUTHEAST CO TO THE SOUTHERN
TX PANHANDLE/TX SOUTH PLAINS/CAPROCK VICINITY INCLUDING THE
PLAINVIEW VICINITY TO SOUTH OF CHILDRESS.

WITH TIME...TSTMS SHOULD INCREASE/ULTIMATELY DEVELOP EAST-SOUTHEAST
ACROSS THE TERRAIN-ADJACENT PLAINS OF SOUTHEAST CO/NORTHEAST NM...AS
WELL AS THE WESTERN PORTIONS OF THE TX PANHANDLE/TX SOUTH PLAINS.
WHILE A MID LEVEL FLOW WEAKNESS IS ASCERTAINED BETWEEN 1-4 KM PER
12Z OBSERVED RAOBS/LATEST PROFILER DATA...GRADUALLY STRENGTHENING
W-SW FLOW ALOFT AND VEERING WIND PROFILES /ESPECIALLY ALONG THE
MODIFYING EFFECTIVE WARM FRONT/ WILL SUPPORT SUPERCELL STRUCTURES.
SEVERE HAIL AND A TORNADO OR TWO WILL ALSO BE POSSIBLE LATE THIS
AFTERNOON/EARLY EVENING...THE LATTER ESPECIALLY WITH ANY STORM
DEVELOPING NEAR/INTERACTING WITH THE EFFECTIVE WARM FRONT ACROSS THE
TX PANHANDLE/TX SOUTH PLAINS/CAPROCK VICINITY WHERE LOW LEVEL FLOW
IS BACKED TO SOUTHEASTERLY.

Today's severe weather outlook


HERE IS A SLGT RISK OF SVR TSTMS THIS AFTERNOON INTO EARLY
TONIGHT FROM EXTREME NW TX INTO SE CO...

...THERE IS A SLGT RISK OF SVR TSTMS THROUGH LATE EVENING FOR
UT...WRN CO...SE ID...SW WY...

...SE TX PANHANDLE TO SE CO THIS AFTERNOON THROUGH EARLY TONIGHT...
LOW-LEVEL MOISTURE IS RETURNING NWD ACROSS W/NW TX WITH BOUNDARY
LAYER DEWPOINTS NOW IN THE MID-UPPER 50S INTO THE PVW-ABI-SPS
AREA...AND A SLOW INCREASE IS EXPECTED THIS AFTERNOON WITH CONTINUED
MOISTURE ADVECTION AND LATENT HEAT FLUX FROM THE MOIST GROUND.
MEANWHILE...CLOUD EROSION AND DAYTIME HEATING FROM S TO N WILL
CONTRIBUTE TO DIFFERENTIAL HEATING AND HELP CONSOLIDATE A
SLOW-MOVING WARM FRONT ALONG THE CAO-AMA-CDS-SPS CORRIDOR...ROUGHLY
ALONG THE RED RIVER INTO PALO DURO CANYON. THIS SURFACE BOUNDARY
WILL SERVE TO FOCUS THUNDERSTORM DEVELOPMENT AS CONVECTIVE
INHIBITION WEAKENS THIS AFTERNOON.

MODERATE INSTABILITY /MLCAPE OF 1000-2000 J PER KG/ IS EXPECTED THIS
AFTERNOON ALONG THE FRONT AND E OF A DIFFUSE DRYLINE. THIS
INSTABILITY...IN COMBINATION WITH A GRADUAL INCREASE IN LOW-MIDLEVEL
FLOW...WILL CONTRIBUTE TO AN ENVIRONMENT FAVORABLE FOR SUPERCELLS
THIS AFTERNOON INTO EARLY TONIGHT...ESPECIALLY IN THE AREA BETWEEN
PVW-AMA-CDS. FORECAST HODOGRAPHS SHOW FAVORABLE VERTICAL WIND SHEAR
FOR PERSISTENT STORMS...AND AN INCREASE IN LOW-LEVEL SHEAR LATE THIS
EVENING WITH A DEVELOPING 25-35 KT SLY/SSELY LLJ. A COUPLE OF
TORNADOES...LARGE HAIL...AND ISOLATED DAMAGING WINDS WILL ALL BE
POSSIBLE FROM MID-LATE AFTERNOON THROUGH AT LEAST EARLY TONIGHT.
