SATELLITE ANALYSIS AND TRENDS...LATEST IR IMAGE SHOWING -79C TOPS
OVER FRANKLIN COUNTY/NE HOPKINS COUNTY IN NE TX WITH VIS SHOWING A
DISTINCT OVERSHOOTING TOP.  MANUAL ESTIMATES OF UP TO 2.0” IN A 30
MIN TIME PERIOD IN LOCALIZED AREAS IN THE COUNTES MENTIONED ABOVE GIVEN
PW VALUES NEAR 2.0” PER GOES SOUNDER/GPS DATA.  STORM TOTALS SHOULD
NOT BE MUCH HIGHER THAN THAT GIVEN EWD MOVEMENT OF THE STORMS HOWEVER.
AUTOMATES/MANUAL ESTIMATES ALSO SHOWING UP TO 2.5” NEAR THE HUNT/DELTA
COUNTY BORDER IN NE TX.

IN NW LA...ALSO SEEING STATIONARY/SLOW MOVING CONVECTION WITH CLOUD
TOP TEMPS OF -72C OVER BOSSIER/CADDO/DE SOTO PARISHES.  WITH SIMILAR PW
VALUES OR APPROX 2.0”..ESTIMATES OF UP TO 2.5” IN THE LAST HOUR OR SO
IN SOME LOCATIONS UNDER MERGERS SEEN NEAR THE BOSSIER/CADDO PARISH BORDER.

EXPECTING RAIN RATES UP TO 2.0”/30 MIN TO CONTINUE FOR NE TX CONVECTION
AS IT MOVES EWD AND SLIGHTLY LOWER RATES OF 1.0”-1.25”/30 MIN FOR THE
NW LA CONVECTION WHICH LOOKS TO REMAIN STATIONARY.  CONVECTION LOOKS TO BE
DEVELOPING BETWEEN THE TWO CONVECTIVE AREAS..SUGGESTING A POSSIBLE MERGER
IN THE NEXT COUPLE OF HOURS.  IF A MERGER OCCURS BETWEEN THE 2 CONVECTION
AREAS...RAIN RATES INVOF MARRION/HARRISON COUNTIES IN TX COULD BE ON THE
ORDER OF 2.5”/30 MIN COULD OCCUR IN LOCALIZED AREAS UNDER THE MERGER.

CHECK WEB IN APPROX 10-15 MIN FOR GRAPHIC AND HYDORESTIMATOR ESTIMATE.
