Thunderstorms are not expected today or tonight over the continental USA. ...Synopsis/Forecast... A moderately amplified but progressive split upper-flow regime will exist over much of the CONUS, particularly to the west of an elongated upper trough over the Midwest and East. The prevalence of high pressure east of the Rockies and relatively dry/stable conditions will considerably limit the potential for thunderstorms. Air mass modification will occur with early stage low-level moisture return over the western Gulf of Mexico, to the south of a southward-advancing front tonight across Texas and Louisiana. Forecast soundings suggest that thermodynamic profiles will not be particularly conducive to thunderstorms tonight, even while some convective showers may increase late tonight/early Monday toward the Texas coastal vicinity. ..Guyer.. 12/31/2023 Read more View the full article Quote Link to comment Share on other sites More sharing options...
