SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 02/06/13 1019Z SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404 LATEST DATA USED: GOES-E 1015Z GOES-W 1000Z GG . LOCATION...S TEXAS... . ATTN WFOS...HGX...CRP...EWX... ATTN RFCS...WGRFC... . EVENT...TRAINING...BACKBUILDING . SATELLITE ANALYSIS AND TRENDS...WV LOOP SHOWS E-W SLIGHTLY ELONGATED UPPER LOW ACROSS CENTRAL WEST TEXAS IS LIFTING SLOWING NEWARD AND WITH A DEEP WSWLY FLOW WITH EMBEDDED WEAK S/W AND ASSOCIATED WIND SPEED MAXIMA AIDING LOW LEVEL CONVERGENCE AND SLIGHT PRESSURE FALLS. ADDITIONALLY SUPPORTING INCREASING LOW LEVEL FLOW ALONG THE COASTAL FLATLANDS OF NE MEXICO INTO S TX WITH AN INCREASE OF PWS FROM 1-1.25" EARLY THIS MORNING TO AROUND 1.4-1.6" ACROSS THE SAME AREA. FIRST IMPULSE HAS ROTATED THROUGH WITH THE NOSE OF THE 80KT SPEED MAX LEADING TO TRIGGERING OF THE SECOND CURRENT OVER ATASCOSA COUNTY. THESE COMPLEXES HAVE BEEN PRODUCING 1-1.5"/HR RATES GIVEN RELATIVELY WARM TOPS AND MODERATE AVAILABLE MOISTURE... LEAVING A SWATH OF 2-3" TOTALS ACROSS WEBB AND LASALLE EVENTUALLY TO KARNES BUT NOT ENOUGH TO REACH FFG VALUES ATTM. . AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED BELOW IN APPROXIMATELY 10-15 MINUTES. . SHORT TERM OUTLOOK VALID 1200-1800Z...MEDIUM CONFIDENCE FACTOR IN SHORT TERM OUTLOOK... PERSISTENT CONVECTION COULD BE LEADING TO THE DEVELOPMENT OF A COLD POOL POTENTIALLY LEADING TO INCREASED FRONTOGENSIS ACROSS S TX... WITH PERPENDICULAR 20-25KT 925MB FLOW... ISENTROPIC FORCING ACROSS THIS ENHANCED BOUNDARY COULD INCREASE COVERAGE AND INCREASE MST FLUX FOR MORE EFFICIENT CELLS. WITH OR WITHOUT THIS FRONTOGENETICAL FORCING... CONTINUED UPSTREAM MIDLEVEL FORCING CONTINUES TO SUPPORT BACKBUILDING CELLS INTO THE FRONT RANGE OF THE SIERRA MADRE. WIND PROFILES ALOFT WILL ALSO SUPPORT CONTINUED ENELY MOVEMENT FOR CONTINUED TRAINING... EVENTUALLY ECLIPSING THE HIGH FFG VALUES IN THE AREA. . ....NESDIS IS A MEMBER OF 12 PLANET.... .
