SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0131 AM CST Sun Feb 07 2021 Valid 091200Z - 101200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe storms are not expected on Tuesday. ...Synopsis... A broad upper trough will remain over the CONUS on Tuesday. A shortwave impulse migrating through this larger-scale trough will dig across the southwestern U.S., resulting in weak surface lee troughing over the southern High Plains. Meanwhile, a cold front will move offshore the northeast and mid-Atlantic coasts, while a stationary boundary remains draped across central TX and the northern Gulf coast. As the upper shortwave trough pivots eastward across the Southwest, south/southwesterly low level flow will continue to support warm advection and isentropic ascent along the Gulf coast. Showers and isolated thunderstorms will continue to be possible, though forcing will remain weak and any appreciable instability will remain offshore, precluding severe thunderstorm potential. ..Leitman.. 02/07/2021
