    SPC 0100Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0804 PM CDT Fri Mar 22 2019 Valid 230100Z - 231200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR PORTIONS OF THE TX PANHANDLE/SOUTH PLAINS INTO FAR WESTERN OK... ...SUMMARY... A few severe thunderstorms will be possible through mid-evening across parts of the Texas/Oklahoma Panhandles and South Plains regions. Large hail and locally severe wind gusts are the primary threats. ...West TX...TX/OK Panhandles...Western OK... A broken line of thunderstorms is propagating eastward across the TX Panhandle at 01Z. While low-level moisture is relatively limited (dewpoints in the upper 40s/low 50s F), steep midlevel lapse rates and cold temperatures aloft (as noted on 00Z AMA sounding) are still supporting MLCAPE of 500-1000 J/kg. 40-50 kt of effective shear continues to support organized storm structures, with a few embedded supercell structures ongoing despite the increasingly linear storm mode. While the severe threat may be past its peak, ongoing activity will continue to pose some hail and wind risk until around 03-04Z, with some backbuilding possible immediately to the southwest of the ongoing line. See MCD 226 for more details regarding the short-term threat in this area. Further south, convection has struggled to deepen across the TX South Plains. While there is still a small window a surface-based storm or two to pose a hail threat, it appears that the primary severe threat for the remainder of the evening will be further north with ongoing convection. ..Dean.. 03/23/2019 Read mor […]
