Severe thunderstorms are not expected on Christmas Day (Wednesday). ....Discussion... A lead southern-stream shortwave trough will tend to weaken across the Lower Mississippi Valley/Tennessee Valley on Wednesday, while a secondary shortwave trough modestly amplifies as it progresses east-southeastward over the southern Rockies toward far west Texas Wednesday night. Some thunderstorms may linger during the day across Louisiana and the upper Texas coast, and possibly into other parts of the Lower Mississippi Valley. Related to the secondary shortwave trough, isolated elevated thunderstorm development may also occur late Wednesday night across far eastern New Mexico into west/northwest Texas including the Texas Panhandle, with forecast soundings plausibly showing a couple hundred J/kg MUCAPE across this region by daybreak (12z) Thursday. Additionally, a few thunderstorms could again occur near the coastal Pacific Northwest/northern California Wednesday night as a shortwave trough/frontal band approaches and mid-level lapse rates steepen. Little or no severe-weather potential is currently expected with any of these scenarios, largely attributable to minimal buoyancy in each instance. ...Guyer.. 12/23/2024 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
