.
SATELLITE ANALYSIS AND TRENDS...LATEST VIS IMAGERY SHOWS AREAS
ACROSS CENTRAL TX THAT ARE SE OF THE UPPER LVL LOW..CENTERED NEAR
43N/101W.. ARE BEGINNING TO SEE CU DEVELOPING WHERE ONLY AN HR BEFORE
SKIES WERE RELATIVELY CLEAR.  THIS AREA WHERE CU ARE FORMING IS NEAR KSNK
SOUTHEAST TO KSEP.  ENHANCED UVVS FROM THE UPPPER LOW SLOWLY MOVING EWD
AND UPPER LVL DIVERGENCE OF 20-30 UNITS BASED ON GOES STLT WIND FIELDS
SHOULD PROVIDE ENOUGH UPWARD VERTICAL MOTION FOR CONVECTION TO DEVELOP.
LVL MOISTURE FLUX CONTINUES TO BE IMPRESSIVE WITH 18Z PROFILER 925-850MB
WINDS FROM THE SSW AT 40-45KTS ACROSS CENTRAL AND E TX PULLING GULF
MOISTURE NORTHWARD.  BEST UPPER LVL JET DYNAMICS REMAIN TO THE SOUTH
ACROSS S TX..BUT A MID-LVL WAVE SEEN IN WV EMBEDDED IN THE SOUTHERN STREAM
IS OF SOME CONCERN AS IT MAY HELP TO FURTHER THE CONVECTIVE DEVELOPMENT
ACROSS N CENTRAL TX AND S/CENTRAL OK.

DAYTIME HEATING IS ALSO EXPECTED TO HELP FUEL THE INSTABILITY AS SKIES
HAVE BEEN ABLE TO BE MOSTLY CLEAR FOR A FEW HRS SE OF THE UPPER LOW.
ADDITIONAL RAINFALL AMOUNTS COULD BE UPWARDS TO 1-2" E AND NE OF THE
UPPER LOW ACROSS N CENTRAL TX INVOF OF KING COUNTY SE TO TARRANT COUNTY
AND EXTENDING NORTHWARD INTO CENTRAL OK TO AROUND MCINTOSH COUNTY AND
NE TO MAJOR COUNTY.
