Isolated thunderstorms should occur Thursday across parts of central/southern California and southern Arizona. Severe thunderstorms are not expected. ...Synopsis and Discussion... An upper low should be centered well off the coast of southern CA early Thursday morning. This low is expected to drift gradually southward through the day, before moving more eastward towards the coast overnight and into Friday morning. Large-scale ascent, ample mid-level moisture, and cold mid-level temperatures associated with this upper low should encourage isolated thunderstorms along and near the central/southern CA coast through the period. As the low moves gradually eastward, showers and occasional thunderstorms are forecast to expand eastward across southern Arizona through early Friday morning. Weak instability should preclude a meaningful threat for severe thunderstorms across these areas. ..Gleason.. 12/20/2023 Read more View the full article Quote Link to comment Share on other sites More sharing options...
