What was reported inside it

Time	Report	Where	Remark
Jun 19, 8:40 PM CDT	FUNNEL CLOUD	5 Nw Cotulla, TX	NEAR FARM TO MARKET ROAD 468.

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Del Rio, TX (KDLF), launched 00:00Z, 1.2 hours before the alert went out and 179 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE CORPUS CHRISTI TX

.DISCUSSION...SEE AVIATION SECTION FOR 00Z TAFS.

&&

.AVIATION...MID LEVEL CIRCULATION CONTINUES TO DRIFT NORTHWARD
BETWEEN EAGLE PASS AND DEL RIO WHERE CONVECTION HAS INCREASED IN
THE PAST HOUR. SCATTERED CONVECTION HAS DEVELOPED IN LOW LEVEL
CONVERGENCE ZONE OVER THE WESTERN BRUSH COUNTRY. EXPECT STORMS
WILL AFFECT LRD AREA WITH MVFR CEILINGS/VSBYS AND GUSTY WINDS
THROUGH THE EVENING. WATCHING AREA OF CONVECTION OVER NORTHERN
NUEVO LEON THAT WAS MOVING TO THE NORTH-NORTHEAST. WILL KEEP
A MENTION OF TSRA IN LRD TAF THROUGH 08Z. GOES SOUNDER SHOWS
DRIER AIR OFF THE COAST...WILL SHOW A SLIGHTLY SLOWER ONSET OF
MVFR CIGS FOR COASTAL PLAINS WITH WIDESPREAD MVFR CIGS EXPECTED
BY 08Z. LIGHT WINDS MAY LEAD TO PATCHY AREAS OF FOG IN THE VCT
AREA AROUND DAYBREAK LEADING TO MVFR VSBYS. ISOLATED STREAMER
SHOWERS WILL BE POSSIBLE OVER THE COASTAL PLAINS FRIDAY MORNING
FROM 14Z-19Z WITH MVFR CIGS. EXPECT VFR CONDITIONS AREA WIDE BY
19Z FRIDAY.

&&

.PREV DISCUSSION... /ISSUED 310 PM CDT THU JUN 19 2014/

SHORT TERM (TONIGHT THROUGH FRIDAY NIGHT)...MAIN ISSUE ARE THE
POPS TONIGHT AND FRIDAY...ESPECIALLY OVER THE EXTREME WESTERN
AREAS. 4 KM MODELS (HRRR AND TTU) ARE NOT SHOWING MUCH
TONIGHT...BUT DID NOT SHOW TOO MUCH LAST NIGHT EITHER. BOTH GFS
AND NAM ARE SHOWING GOOD UVV OVER THE AREA ASSOCIATED WITH
CONVECTIVE VORT LOBE (VORT LOBE SEEN ON SATELLITE AND
RADAR)...WHICH SHIFTS NORTH OVERNIGHT. NORMALLY (AS IT IS NOW)
ATMOSPHERE PRETTY MUCH WORKED OVER AND THAT OFTEN MEANS NOT MUCH
IN RAIN UNTIL AIRMASS DE-STABILIZES. HOWEVER...DO NOT WANT TO
IGNORE THESE FEATURES IN THE SYNOPTIC MODELS...ESPECIALLY SINCE
PWATS ARE ABOVE 2 INCHES IN THIS AREA. THE LONG AND SHORT OF IT IS
THAT THERE IS A CHANCE FOR PRECIP MAINLY ALONG THE RIO GRANDE FOR
TONIGHT...WITH RAPIDLY DIMINISHING POPS FARTHER EAST FOR THIS
EVENING (GRIDDED GFS AND NAM GOING HIGHER ON POPS BUT WILL NOT
GOAS HIGH FOR NOW AND STAY CLOSER TO MOS VALUES). REASONABLE
MOISTURE ADVECTION AND COASTAL CONVERGENCE COULD GENERATE A FEW
SHOWERS OVER THE SOUTHERN COASTAL AREAS OVERNIGHT...WITH ACTIVITY
SPREADING INLAND ON FRIDAY. GFS IS GOING HIGHER ON POPS THAN NAM
(FOR A CHANGE)...AND WITH SOME MOISTURE ADVECTION FRIDAY WILL
SPLIT THE DIFFERENCE ON FRIDAY AND GO WITH SLIGHT CHANCE POPS
AREA-WIDE. AFTER THAT...RAIN WILL BE LIMITED TO THE RIO GRANDE
(ONCE AGAIN) AS PWATS AGAIN NEAR 2 INCHES WEST OF THE CWFA (AND
SOME COULD MOVE INTO WESTERN WEBB AND LA SALLE COUNTIES DURING THE
EVENING). FOR TEMPERATURES...SLIGHTLY LOWER TEMPERATURES EACH
PERIOD AS MORE CLOUDS ON FRIDAY AND LESS WIND DURING THE OVERNIGHT
HOURS.

MARINE (TONIGHT THROUGH FRIDAY NIGHT)...WINDS SHOULD STAY BELOW
SCA TONIGHT AND REMAIN SO THROUGH FRIDAY NIGHT. SOME SHOWERS
POSSIBLE TOWARD DAWN AND IN THE MORNING MAINLY NEAR THE COAST.

LONG TERM (SATURDAY THROUGH THURSDAY)...MODELS CONTINUE TO HAVE A
DIFFICULT TIME WITH THE UPPER PATTERN ACROSS TX DURING THE EXTENDED.
LATEST RUNS PROG THE MID/UPPER RIDGE TO ONLY SLIGHTLY BUILD ACROSS
THE E CWA FROM THE E WITH A SHORT WAVE TRACKING ACROSS THE NW CWA
THROUGH THE WEEKEND. PWATS ARE PROGD TO BE NEAR 2 INCHES ACROSS THE
RIO GRANDE PLAINS ALONG WITH SOME INSTABILITY. THEREFORE...HAVE
INTRODUCED A SLIGHT CHC OF SHRA/TSRA ACROSS THE W AND NW CWA FOR
BOTH SAT AND SUNDAY. HAVE ALSO INTRODUCED SCHC OF -SHRAS WITH A 10
POP ACROSS THE COASTAL BEND EACH MORNING IN RESPONSE TO LOW LEVEL
CONVERGENCE. BY AFTERNOON...SUBSIDENCE SETS UP BEHIND THE SEA BREEZE
ACROSS THE E CWA. BY MONDAY...THE SHORT WAVE IS PROGD BY THE ECMWF
AND GFS TO SHIFT FARTHER E WITH RIDGING ACROSS THE WESTERN CWA.
PWATS/MOISTURE IS PROGD TO LESSEN AS WELL. THUS...KEPT SILENT 10
POPS ON MON. MODEL SOLNS REALLY DIVERGE BY TUE THROUGH THU TIME
FRAME. BASED ON MUCH LOWER PWATS ON TUE...HAVE LOWERED THE 20 POPS
TO 10. BY WED...THE MODELS SOLNS VARY FROM THE GFS HAVING A RIDGE
ACROSS THE W 2/3RDS OF THE CWA...THE ECMWF SHOWING A WEAKNESS ALOFT
DRAPED FROM N TO S ACROSS THE NW CWA AND THE DGEX SHOWING A WEAKNESS
DRAPED FROM SW TO NE ACROSS THE ENTIRE CWA. FOR CONSISTENCY
SAKE...KEPT THE SLIGHT CHC FOR WED AND SILENT 10 POPS FOR THU UNTIL
MODELS CONVERGE ON A SOLN. WENT WITH PERSISTENCE WITH REGARDS TO THE
TEMPS AND WINDS.
