SPC Jan 24, 2022 1630 UTC Day 1 Convective Outlook

SPC 1630Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1010 AM CST Mon Jan 24 2022 Valid 241630Z - 251200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated weak thunderstorms are possible from southeast Texas into southwest Louisiana through tonight. ...Northwest Gulf coast through tonight... Only minor adjustments to the outlook area. Surface cyclogenesis is underway along a baroclinic zone near the middle TX coast, and this cyclone will progress eastward across the northwest/north central Gulf of Mexico in advance of a midlevel shortwave trough now over west TX. Modifying surface warm sector will remain offshore, which will preclude any threat for severe storms inland. Elevated convection will produce occasional lightning flashes in the zone of warm advection/ascent preceding the midlevel trough, based on weak buoyancy and 7-7.5 C/km lapse rates in roughly the 700-500 mb layer. The threat for thunderstorms will spread eastward across southeast TX today and persist into southwest LA through tonight. ..Thompson.. 01/24/2022 Read more CHECK UPDATE ZOOM GRAPHIC
