A threat for damaging wind gusts and a few tornadoes will shift eastward across the Lower Mississippi Valley and central Gulf Coast region tonight. ...01z Update... Mid-level heights will fall significantly across the lower MS during the overnight hours ahead of a short-wave trough that is digging southeast across the Plains. Surface front associated with this feature is surging toward the western Gulf States and currently extends from central AR - northwest LA - southeast TX. Scattered convection is slowly organizing along the surging cold front and a squall line is expected to mature over LA later this evening, then progress east along the central Gulf Coast. Greatest buoyancy at 24/00z extended across southeast TX into western LA and this should aid convective development over the next few hours. ..Darrow.. 12/24/2020
