Scattered, generally weak, thunderstorm activity remains possible late this afternoon through tonight across parts of the Four Corners and southern Rockies into the Texas South Plains and Panhandle vicinity. ...20Z Update... ...Florida... Cloud cover and rain across much of the southeastern Florida Peninsula and Keys have contributed to the maintenance of a generally stable boundary layer, with little forcing in lower-levels to support an appreciable risk for thunderstorms. Some risk for convection capable of producing lightning may linger offshore of coastal areas, mainly along the surface front, to the east of the Greater Miami vicinity. ..Kerr.. 12/13/2023 .PREV DISCUSSION... /ISSUED 1017 AM CST Wed Dec 13 2023/ ...Synopsis/Discussion... A closed mid/upper-level low will continue eastward over the Four Corners area and southern Rockies through tonight, removed from a more progressive belt of westerlies over the northern tier of the CONUS and Canada. Steepening lapse rates and ascent ahead of the aforementioned upper low will support isolated thunderstorm potential from northeast Arizona/southeast Utah into New Mexico especially tonight, while other thunderstorms will be possible today and tonight farther east across eastern New Mexico and western Texas within a persistent warm advection regime. Additionally, a few thunderstorms will be possible across/near south Florida near a convergence zone where a moist air mass persists.
