Mesoscale Discussion 1666

   0855 PM CDT Tue Sep 01 2020

   Areas affected...North Central Texas

   Concerning...Severe potential...Watch unlikely 

   Valid 020155Z - 020330Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Storms along an east west oriented outflow boundary have
   shown occasional rotation. Severe potential remains uncertain.

   DISCUSSION...Numerous thunderstorms are ongoing across central Texas
   along and south of a remnant outflow boundary. A warm and moist
   airmass south of the boundary is supporting MLCAPE of 2000-3000
   J/kg. SPC mesoanalysis also shows backed low-level winds are
   supporting ESRH of 150-300 m2/s2. A few storms have shown occasional
   organized rotation and the environment will likely remain favorable
   for low-level mesocyclogenisis this evening. Storms may struggle to
   maintain unimpeded inflow as the outflow counties to slowly shift
   south. While there remains considerable uncertainty on storm
   severity, gusty winds, hail, and a brief tornado will be possible
   for the next couple of hours.
