Severe thunderstorms are not expected through tonight. ...Synopsis/Discussion... The mid/upper-level pattern will be characterized by a belt of gently difluent, west-northwesterly northern-stream flow from the Pacific Northwest to the Great Lakes. This flow will weaken considerably and become much more difluent over the Ohio Valley, mid Mississippi Valley and Appalachians. The strongest flow aloft will be well-displaced from any substantial low-level moisture/theta-e, which is expected to remain along and south of a quasistationary front draped across north-central FL. Scattered daytime thunderstorms are expected to form along FL East and West Coast sea breezes, shifting inland as the boundaries (including outflows from the first generation of convection nearer the coasts) merge. Weak deep-layer flow and lack of shear will preclude organized severe potential. Localized strong gusts are possible in wet downbursts with enhanced lift along colliding boundaries, 1500-2000 J/kg preconvective MLCAPE, and rich inflow- layer moisture (surface dewpoints 70s F and PW commonly over 2 inches). Elsewhere, very isolated/brief lightning may occur near the AZ/NM border and Mogollon Rim, but with barely enough moisture for convection, coverage is expected to be too small for a 10% area. ..Edwards/Dean.. 10/02/2024 Read more View the full article Quote Link to comment Share on other sites More sharing options...
