SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 09/09/07 1755Z
SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-763-8678
LATEST DATA USED: GOES-EAST:1745Z  JS
.
LOCATION...NW TO N CENT TEXAS/SW TO S CENT OKLAHOMA...
.
ATTN WFOS...FWD...OUN...LUB...AMA...
ATTN RFCS...ABRFC...WGRFC...
.
EVENT...MERGING SLOW MOVING CELLS CREATING SHORT TERM HEAVY RAIN THREAT
JUST NORTHEAST OF CHILDRESS TX NEAR TX/OK BORDER. MAY ALSO NEED TO MONITOR
NEW CELL DEVELOPMENT NORTH OF OLD OUTFLOW BOUNDARY OVER S OK/N TX CLOSE
TO RED RIVER.
.
SATELLITE ANALYSIS AND TRENDS...GOES IMAGERY THROUGH 1745Z SHOWS
SIGNIFICANT CLOUD TOP COOLING/ENHANCEMENT ACROSS AREA NEAR TX/OK
BORDER INCLUDING PORTIONS OF CHILDRESS(TX)/NW HARDEMAN(TX)/HARMON(OK)
COUNTIES IN REGION OF GOOD SFC CONVERGENCE BETWEEN FORCING FROM OLD
MCV OVER TX PANHANDLE AND NE/E FLOW BEHIND SFC OUTFLOW BOUNDARY MOVING
SOUTHWARD ACROSS N TX. SATELLITE ENHANCEMENT ALONG WITH GOOD MOISTURE
PRESENT NEARBY YIELD ESTIMATED RATES OF 2.0-2.5"/HR ESPECIALLY IN THE
LOCATIONS OF CELL MERGERS THAT ARE OCCURRING WITH ACTUAL AMOUNTS LIKELY
APPROACHING THESE FIGURES AS WELL IN THE PAST HOUR DUE TO THE VERY SLOW
MOVEMENT. BELIEVE THIS ACTIVITY WILL CONTINUE TO MOVE VERY SLOWLY OVER
THE NEXT HOUR LEADING TO A GREATER HEAVY RAINFALL THREAT IN THIS REGION
AS TOTALS INCREASE RAPIDLY. TRENDS SEEN IN VISIBLE IMAGERY LOOP ALSO IMPLY
NEW DEVELOPMENT OCCURRING FARTHER TO THE EAST ALONG RED RIVER REGION OF S
CENT OK/N CENT TX. THESE NEWLY FORMING CELLS ALSO ARE NOT MOVING MUCH SO
LOCALIZED HEAVY RAIN POTENTIAL COULD MATERIALIZE QUICKLY. THERE IS ALSO
SOME CHANCE THAT AREA BETWEEN NW TX/SW OK BATCH AND LINE FORMING ALONG
RED RIVER COULD FILL IN DURING THE NEXT HOUR OR SO. FINALLY, LONG LIVED
CLUSTER OF STORMS WHICH MOVED SOUTHWARD FROM OK/AR INTO NE TX CONTINUES TO
SURGE SOUTH AND SOUTHWESTWARD AND COULD APPROACH THE FAR EASTERN PORTIONS
OF THE DALLAS REGION IN THE NEXT HOUR. RATHER BRIEF BUT INTENSE SATELLITE
ESTIMATED RAINFALL RATES OF AT LEAST 2"/HR ARE ACCOMPANYING THIS LINE.
