SATELLITE ANALYSIS AND TRENDS...LINE OF STRONG CELLS ACROSS CENTRAL TX
IS ALONG THE TAIL END OF A COLD FRNT WHICH EXTENDS ACROSS MOST OF THE
NATIONS' MIDSECTION..FROM WI TO TX. STRONGEST PART OF THIS LINE APPEARS TO
BE IN THE OUTWARD BOWING SECTION OF THE LINE INVOF K3T5 WHERE CLOUD TOPS
ARE AT -70C AND MAJORITY OF RECENT LIGHTNING STRIKES ARE SEEN. ANOTHER
SECTION OF THE LINE FROM KDRT TO NEAR KHDO IS STRONGER AS WELL. HOWEVER
LAST FEW STLT IMAGES HAVE INDICATED STRENGTHENING OF THE REST OF THE
LINE NEWD TO KLHB AND RADAR IMAGERY CONFIRMS THIS TREND. WITH HVY RAIN
ALREADY OCCURRING OVER HAYS/TRAVIS COUNTIES..ADDTL DVLPMT NEWD JUST
BEHIND THE PRIMARY LINE OF STORMS WILL ONLY ENHANCE PROBLEMS ALREADY
ONGOING IN THOSE AREAS..THOUGH DO NOT THINK THESE DVLPING CELLS WILL
BE AS STRONG INVOF OF S CENTRAL TX. FARTHER NEWD WHERE THE ATMOS HAS
NOT YET BEEN WORKED OVER BY STORMS..SOME STRONGER CELLS ARE CAPABLE OF
DVLPING THOUGH IT SHOULD STILL MOSTLY REMAIN A SEVERE THREAT.
.
AM ALSO CONCERNED FF THREAT ALONG THE SW SECTION OF THE LINE INVOF KINNEY
COUNTY. AUTOMATED STLT ESTIMATES INDICATE RAINFALL RATES OF 1.5-2"/HR
ARE OCCURRING WITH 1 HR ESTIMATES ENDING 1415Z OF 1.3" HAVING FALLEN. IN
ADDITION TO THIS AMOUNT..UP TO ANOTHER 1" MAY HAVE FALLEN OVER S KINNEY
COUNTY AS THE COLDEST TOP SLOWLY SHIFTED SWD. GOES SOUNDER/GPS VALUES
INDICATE PW VALUES OF UP TO 1.9" S/SE OF THE LINE OF CNVTN AND DWPTS IN
THE HIGH 60S-LOW 70S SO AMPLE GULF MOISTURE IS PRESENT TO FEED THESE
STORMS. LIS INDICATE A VERY UNSTABLE AIR MASS..PARTICULARLY INVOF
KCOT/KDLF SO THOUGH CNVTN SHOULD CONTINUE TO PUSH SWD..WILL WANT TO
KEEP WATCH ON THIS AREA FOR ANY CELLS THAT GET CAUGHT UP. WILL CONTINUE
TO MONITOR.
