Additional totals of 2 to 4+ inches will be possible. DISCUSSION...1450Z radar imagery showed a lingering MCS just north of the DFW Metroplex with areas of training that have MRMS-estimated hourly rainfall values of 1 to 2 inches. Infrared satellite imagery has shown overall warming of cloud tops over the past two hours but a lingering flash flood threat remains over locations just downstream from the ongoing MCS for the next 1 to 2 hours. A very moist (PWATs near 2 inches) and unstable (MLCAPE 1000-1500 J/kg) airmass was in place south and east of the MCS cold pool with 30 to 35 kt of SSW 850 mb flow to its south. The MCS is expected to continue tracking eastward over the next few hours with an overall weakening, though localized new convective bursts remain possible. Areas of training will remain likely in the short term with 1 to 2 inches of rain over an hour for portions of northern TX. Additional convective development may occur over southeastern OK as the MCS/cold pool moves through, and while these cells are expected to be largely progressive from west to east, they could move across portions of the Ouachita Mountains which picked up 3 to 6 inches of rain over the past 24 hours. Farther south into TX, There could be new convective development along the southeastern flank of the MCS as it progresses east near or just after 18Z. Over and just southeast of the DFW Metroplex is another area that received heavy rain and flash flooding before sunrise this morning. Isolated pockets of 2 to 4+ inches will be possible through early afternoon. Otto ...Please see www.wpc.ncep.noaa.gov for graphic product... ATTN...WFO...FWD...LZK...OUN...SHV...TSA...
