Valid 180536Z - 180730Z
The severe weather threat for Severe Thunderstorm Watch 709
continues.
SUMMARY...Strong storms continue in a frontal band crossing western
Texas, where damaging winds and marginal hail are possible.
DISCUSSION...Latest radar loop shows a broken band of locally
vigorous convection occurring ahead of a cold front
organizing/moving eastward across far West Texas at this time. Very
strong flow aloft -- including winds in excess of 50 kt just 1km AGL
-- continues to support local storm organization, including bowing
segments at least transiently organizing within the convective band.
At this time, weak instability remains a limiting factor, in terms
of more robust severe risk. With that said, a surface warm front
continues shifting rapidly northward/northwestward across central
Texas, at the leading edge of a high theta-e (low 70s dewpoints)
airmass. As storms advance slowly eastward, and higher theta-e air
continues advecting northwestward, an eventual uptick in risk is
expected.
