 Mesoscale Discussion 0429
NWS Storm Prediction Center Norman OK
1006 PM CDT Tue Apr 23 2019 Areas affected...Texas Big Bend and Edwards Plateau into north
central Texas Concerning...Severe Thunderstorm Watch 95... Valid 240306Z - 240400Z The severe weather threat for Severe Thunderstorm Watch 95
continues. SUMMARY...A new severe weather watch may be issued by 1030-11 PM
CDT, as at least some severe weather potential probably will persist
into the overnight hours. DISCUSSION...East and south of the Dallas-Fort Worth metroplex, and
east of the Interstate 35 corridor to the south, weaker boundary
layer instability appears likely to prevail in association with some
combination of continuing surface cooling, stronger mid-level
inhibition, and warmer air above than across much of west Texas. This is expected to result in considerable weakening of ongoing
storms now across and southwest of the Dallas-Fort Worth metroplex
as it spreads eastward through midnight-1 AM. However, in the presence of continuing moderately large CAPE in
excess of 1000 J/kg, strong to severe storm development may persist
into the overnight hours and spread across parts of the Edwards
Plateau into the Hill Country. Additional storms may develop off
the higher terrain to the west of the Rio Grande River and spread
northeastward, ahead of the mid-level closed low gradually turning
eastward toward the Big Bend region. ..Kerr.. 04/24/2019 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...FWD...EWX...SJT...MAF... LAT...LON 31730249 32090151 32119992 32719815 33279735 32829607 31249759 30099830 29309919 28910046 28850156 28920231 29430355 29710383 31730249
