345 AWUS01 KWNH 141747 FFGMPD LAZ000-ARZ000-TXZ000-OKZ000-142300- Mesoscale Precipitation Discussion 0433 NWS Weather Prediction Center College Park MD 146 PM EDT Sat Jun 14 2025 Areas affected...portions of eastern Oklahoma through central/southwest Arkansas and far northeast Texas Concerning...Heavy rainfall...Flash flooding possible Valid 141746Z - 142300Z Summary...An intensifying convective complex over eastern Oklahoma will sweep through the discussion area and pose a risk of areas of 1-2 inch/hr rain rates at times. These rates are expected to cause localized/isolated flash flood issues through 23Z/6p CDT. Discussion...Over the past couple hours, a linear MCS has materialized over eastern Oklahoma from near Muskogee to near Ada. Cells within this complex were moving east-southeastward at approximately 25-30 knots, which has mostly kept peak rain rates at around 1-2 inches/hr (just shy of FFG thresholds) so far this afternoon. As storms migrate downstream through the afternoon and early evening, a few considerations for increasing flash flood potential exist, including: 1) deepening convection ahead of the complex, which should allow for a few areas of mergers to prolong/increase rain rates above 2 inches/hr and 2) the orientation of the complex itself - which may allow for localized training on occasion. FFG thresholds should be breached in a few areas of this complex moves through, with low-lying/sensitive areas of particular concern for flash flooding. Over time, a few of these storms may reach areas just north/east of Little Rock that experienced 3-5 inch rainfall totals just a few hours ago. These areas may also be locally sensitive and prone to flooding. Cook ...Please see www.wpc.ncep.noaa.gov for graphic product... ATTN...WFO...FWD...LZK...OUN...SHV...TSA...
