SPC May 16, 2021 0100 UTC Day 1 Convective Outlook

SPC 0100Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0755 PM CDT Sat May 15 2021 Valid 160100Z - 161200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF THE CENTRAL AND SOUTHERN PLAINS... ...SUMMARY... Scattered strong to severe thunderstorms will continue across the central/southern High Plains this evening. Hail and wind are the primary hazards. ...

Central/Southern Plains... Strong boundary-layer heating once again was the primary instigator in convective initiation across the central/southern High Plains this afternoon. An elongated corridor of strong/severe convection has evolved from southeast CO-western OK Panhandle-along the TX/NM border into northern Mexico southwest of DRT. Modest steering currents between I-40 and I-20 will result in slow eastward propagation this evening. Somewhat stronger flow could allow for upscale growth with activity near Sanderson/Del Rio. Ultimately, an MCS could mature and propagate along the Rio Grande into south TX later tonight. Otherwise, low-level warm advection across KS should encourage significant convection during the overnight hours. In both cases, hail/wind are the primary threats. ...


Elsewhere... A few strong storms will linger this evening across the upper MS Valley and over northeast NV. In both cases, onset of diurnal cooling should result in weakening convection. ..Darrow.. 05/16/2021 Read more LIVE: spc.noaa.gov
