A localized severe thunderstorm risk is possible over parts of the central Gulf Coast later this evening into the early morning. ...Synopsis... Early evening water-vapor imagery shows a mid- to upper-level trough pivoting northeast across the southern Great Plains and northwest Gulf Coast. An extensive rain shield is located immediately ahead of the trough over the central Gulf Coast/lower MS Valley. Although the primary surface low is forecast to develop from northeast OK into the lower MO Valley tonight, a secondary area of low pressure is forecast to develop from southeast LA into MS/AL during the overnight on the northern periphery of the more appreciably modified-Gulf airmass. It remains possible storm development will occur this evening over southeast LA and move downstream into parts of southern MS/AL. Although the incipient severe risk is conditional upon robust storm development (substantial airmass modification will need to occur based on the 00z Slidell, LA 00z raob; 0 J/kg MUCAPE), will continue with the low probability highlight for a brief tornado/localized severe gust late this evening into the overnight. Elsewhere, quiescent conditions will prevail across the East and areas from the High Plains westward to the West Coast. ..Smith.. 12/25/2023 Read more View the full article Quote Link to comment Share on other sites More sharing options...
