SPC Jun 28, 2021 0100 UTC Day 1 Convective Outlook

SPC 0100Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0800 PM CDT Sun Jun 27 2021 Valid 280100Z - 281200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... A few strong thunderstorms will remain possible this evening from the Ozarks to portions of Lower Michigan, and over the southern New Mexico/far west Texas region around El Paso. ...Discussion... Scattered showers and isolated thunderstorms -- a few which remain strong at this hour -- continue from the Ozarks to southern Lower Michigan in the vicinity of the remnant surface baroclinic zone. However, storms have remained largely sub-severe across this region today, and with a diurnal decrease in surface-based instability over the next few hours, severe potential appears likely to further diminish overall. Therefore, the MRGL risk area is being removed from this area. Farther to the southwest, A few stronger storms are ongoing southwest of El Paso, in northern Mexico, where 1000 to 1500 J/kg mixed-layer CAPE is indicated. However, much weaker instability on the U.S. side of the border is correlated with weaker storms per recent radar, and this should remain the case this evening/overnight. Therefore, will also remove the MRGL risk area from the far West Texas vicinity, as well. ..Goss.. 06/28/2021 Read more LIVE:
