SPC Jan 23, 2022 1630 UTC Day 1 Convective Outlook

SPC 1630Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1026 AM CST Sun Jan 23 2022 Valid 231630Z - 241200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated weak thunderstorms are possible across southeast Arizona and southwest New Mexico today. ...AZ/NM/TX through tonight... A closed midlevel low will move slowly eastward from Sonora/southern AZ to far west TX by Monday morning. Cold midlevel temperatures with association steep lapse rates and weak buoyancy will support the potential for isolated thunderstorms, aided this afternoon by surface heating/mixing. Some elevated convection (rooted near 700 mb) may occur farther east in TX overnight, in the zone of ascent preceding the midlevel trough. However, buoyancy will be limited, and it is not clear that cloud depth will be sufficient for lightning production. ..Thompson.. 01/23/2022 Read more CHECK UPDATE ZOOM GRAPHIC
