Isolated non-severe thunderstorms will be possible tonight across west Texas and southeast New Mexico. ...Synopsis... Within a southern stream, a midlevel shortwave trough will move southeastward over NV toward northwest AZ by early Wednesday. Farther east, a modifying air mass will begin to return to south TX and the lower Rio Grande Valley, though moistening farther northwest into west TX/southeast NM will likely occur near and above the 700 mb level. Midlevel lapse rates will be sufficiently steep to allow for the development of weak buoyancy aloft, and warm advection may support a few embedded convective elements capable of producing isolated lightning flashes tonight. Otherwise, gradual low-level moistening will continue across southeast FL in a persistent east-northeasterly flow regime, and across the lower TX coast with onshore flow. Shallow convection/showers are probable in both areas, but the threat for convection deep enough to produce lightning before 12z still appears fairly low. ..Thompson/Gleason.. 12/12/2023 Read more View the full article Quote Link to comment Share on other sites More sharing options...
