SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1127 PM CST Mon Feb 08 2021 Valid 101200Z - 111200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Organized severe thunderstorms are not forecast on Wednesday. ...Synopsis... A shortwave upper trough over the southwestern U.S./northwest Mexico Wednesday morning is forecast to track eastward to the central/southern High Plains and northern Mexico vicinity by Thursday morning. At the surface, high pressure will encompass much of the northern U.S. into the Midwest. The arctic airmass associated with this high pressure will continue surging southward across the southern Plains/TX. The arctic front will sag southward from the mid-South to the lower MS Valley and into south TX. South/southwesterly low/midlevel flow ahead of the front and upper trough will result in a warm advection regime from parts of TX through the Gulf coast states. Isentropic ascent will lead to showers and isolated thunderstorms from TX through portions of the Southeast. Thunderstorm activity will be elevated, to the cool side of the front given boundary-parallel shear vectors. Meanwhile, instability also will remain limited, with higher-quality moisture remaining offshore over the Gulf. As such, organized severe storms are not anticipated. ..Leitman.. 02/09/2021
