environment favorable for surface-based storms, with all severe
modes possible. A WW is being considered for areas downstream. DISCUSSION...An ongoing strong to severe MCS continues from near AUS
to near SAT currently. These storms likely remain slightly elevated
atop a cool surface later left behind from early morning convection. Recent observations suggest that the eastern edge of this cool
layer was eroding due to advection and surface warming, with upper
60s to low 70s F dewpoints now located roughly 50-75 miles
downstream of the ongoing MCS. As these storms migrate eastward,
they will gradually become surface-based, with the ongoing threat
shifting toward damaging winds and perhaps a couple tornadoes. As
such, a Tornado Watch is being considered for areas downstream. ..Cook/Thompson.. 04/24/2019 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...LCH...SHV...HGX...FWD...EWX...
