SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 1253 AM CST Sun Jan 19 2025 Valid 211200Z - 221200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not forecast on Tuesday. On Tuesday, a large upper trough will extend from the upper Great Lakes into the Southwest, and will progress eastward into the Northeast. Meanwhile, another backside speed max will dive southward across the Rockies, while a ridge remains along the West Coast. At the surface, substantial high pressure will be in place from the Great Basin to the East Coast, with dry offshore winds along the Gulf Coast. This high will shift east through the period, but another centroid is forecast over the Intermountain West. There is a low chance of weak elevated instability developing into Wed morning over southern FL, in association with the aforementioned initial upper trough. While some thunderstorms may affect parts of the Gulf of Mexico, poor lapse rates aloft will likely limit even weak thunderstorm potential over land. ..Jewell.. 01/19/2025
