Mesoscale Precipitation Discussion 0821 NWS Weather Prediction Center College Park MD 1117 PM EDT Mon Sep 10 2018
Areas affected...Deep South Texas and Texas Coastline....
Concerning...Heavy rainfall...Flash flooding possible
Valid 110320Z - 110900Z
SUMMARY...Slow moving, highly efficient convection near the coast and stalled mid-level wave in Deep South Texas.
DISCUSSION...At the tail end of the large scale westerly trof, an inverted low level trof and possible closed 850mb wave remains across far Deep South Texas into Northeast Old Mexico. Current GOES-16 satellite suite suggests the MCV/wave is just south of the Rio Grande near Rio Grande City, TX with maximized low level moisture convergence to spark cycling moderate sized updrafts with tops cooling occasionally to -70C. WV suite, denotes the western edge of the Subtropical jet from Central Nuevo Leon to across Starr and paralleling the TX coast before angling north to an exiting mid-level shortwave near Austin to College Station, TX. Moisture remains pooled across Deep South TX, with total PWATs near 2.5". With freezing levels aoa 15Kft, warm cloud processes similar to the past few days remain with scattered convection that develops. Given weak inflow, cells have been maintained about 1-2 hours and with mean cell motions less than 10kts...localized totals over 2-3" remain likely resulting in potential flash flooding.
Later in the period, toward 05/06z, low level surface flow will slightly increase with general confluence along the coast enhanced by frictional convergence particularly near points/bays/coves that will spark new development. Upper level winds are weak, but generally unidirectional to support slightly tilted updrafts (downdrafts) for slightly downstream rainfall that should not choke inflow...leading to persisent heavy rainfall and potential flash flooding along the coast line from Kenedy county to Galveston Bay. HREF mean suggests greatest threat remains near Baffin to Aransas Bay, though a few showers development can be seen as far NW as Matagorda Bay. Increase of 850mb flow toward 07z up to 15kts from the due south has the potential to reduce coastal flash flooding, leading to propagation offshore after 07z...though shifts threat for best coastal convergence toward Galveston. Given repeat nature over past few days, soils have become more saturated and susceptible to hydrophobic conditions leading to greater flooding/inundation to occur. As such flash flooding/inundation is considered possible through 09z.
