EVENT...HVY RAINFALL FROM STRONG CONVECTIVE CELL
.
SATELLITE ANALYSIS AND TRENDS...RECENT IR IMAGERY IS CONTINUING TO SHOW
RAPID INTENSIFICATION OF A SINGLE CONVECTIVE CELL LOCATED ALONG THE
TX/OK BORDER.  CLOUD TOP TEMPS HAVE COOLED FROM -56C TO -64C IN THE LAST
HOUR (ENDING AT 2240Z) AND CONTINUED EXPANSION OF THESE COLDER CLOUD
TOP TEMPS IS ALSO DEPICTED IN IR ANIMATION.  LIGHTENING DATA INDICATES
FREQUENT LIGHTING STRIKES AND VIS IMAGERY SHOWS AN OVERSHOOTING TOP OVER
CENTER OVER WICHITA COUNTY IN TX.  MANUAL STLT ESTIMATES SUGGEST RAINFALL
RATES UP TO 1"/HR IS LIKELY FROM THIS RATHER SLOW MOVING CELL..WHICH IS
ON A SEWD COURSE TAKING IT FROM WICHITA COUNTY THRU CLAY AND MONTAGUE
COUNTIES IN TX AND ALSO IMPACTING SOUTHERN JEFFERSON COUNTY IN OK.
MOISTURE APPEARS TO BE SLIGHTLY LIMITED THRU CENTRAL TX AS THE MOMENT AS
GOES AND GPS PW VALUES ARE AROUND 0.8-0.9" WITH A SOUTHERLY 30KT LLJ PER
STLT WINDS AND PROFILER DATA PROVIDE WEAK/MODERATE MOISTURE ADVECTION.
THIS SHOULD HELP TO LIMIT THE LONGEVITY OF THESE CELLS PRODUCING HVY
RAIN OVER THE NEXT 1-2 HRS.
