SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0151 AM CST Fri Dec 13 2024 Valid 151200Z - 161200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorm potential is expected to remain limited on Sunday. ...Synopsis... An upper trough will migrate east from the Rockies into the Plains on Sunday. As this occurs, a surface low will track across the northern Plains. Meanwhile, a cold front will develop southeast across much of the northern/central Plains through the day. The front will continue southeast through the nighttime hours, becoming positioned from near Lake Michigan southwestward toward the Red River by Monday morning. Southerly low-level flow ahead of the front will allow 60s F dewpoints to spread north across east TX into southeast OK, and eastward across AR/LA. While vertically veering wind profiles typically would support some potential for organized convection, thermodynamics are expected to remain rather poor due to low-level inhibition and weak lapse rates. Furthermore, stronger height falls are not expected across the region until late in the period, further suppressing deep convective potential through much of the forecast period. While isolated elevated convection is possible in the low-level warm advection regime, severe potential appears limited. ..Leitman.. 12/13/2024
