SPC 0600Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1255 AM CDT Fri Apr 19 2024 Valid 201200Z - 211200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF SOUTH-CENTRAL AND SOUTHEAST TEXAS... ...SUMMARY... Marginally severe storms capable of strong wind gusts and hail will be possible on Saturday across parts of south-central and southeast Texas. ...South-central and Southeast Texas... A shortwave trough will move toward the southern Plains on Saturday, as zonal flow remains in place across much of the Gulf Coast region. At the surface, a quasi-stationary front is forecast to be located across south-central and southeast Texas. South of this boundary, a moist airmass will be in place with surface dewpoints in the 60s F. Surface heating will result in destabilization across this airmass during the day. As instability peaks during the afternoon, and as low-level convergence increases along and near the front, scattered thunderstorm development is expected. ECMWF forecast soundings in south-central Texas during the late afternoon suggest that MLCAPE will peak near 1200 J/kg, and that 0-6 km shear will be around 40 knots. This would be favorable for an isolated severe threat. The stronger storms could be associated with isolated damaging wind gusts and hail. However, limited large-scale ascent and poor lapse rates will likely keep any severe threat marginal. ..Broyles.. 04/19/2024
