SPC Jan 16, 2023 0600 UTC Day 1 Convective Outlook

LIVE MAP (ABOVE) ... SPC 1200Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1146 PM CST Sun Jan 15 2023 Valid 161200Z - 171200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Appreciable severe-weather potential is not evident today. ...Discussion... As an upper low off the East Coast drifts slowly northward toward the Canadian Maritimes, and an upstream ridge moves slowly eastward across the Appalachians, a more progressive pattern will prevail farther west. Here, a short-wave trough crossing the mid Missouri Valley early, will shift northeastward to the Upper Great Lakes, while second/complex area of troughing, initially near and just off the West Coast, digs southeastward across central and southern California, likely reaching the Colorado River Valley by the end of the period/Tuesday morning. Showers and embedded thunderstorms are forecast across southern California and into the Desert Southwest, as several upper disturbances -- and an associated surface low, to cross this region through the period. Meanwhile, showers and a few thunderstorms are also expected From the Iowa vicinity southeastward across the mid Mississippi and lower Ohio Valleys, as the aforementioned central U.S. upper trough, and its accompanying surface low, traverse this region. Appreciable severe risk is not anticipated in either of these areas of enhanced convective potential. ..Goss/Bentley.. 01/16/2023 Read more CHECK UPDATE ZOOM GRAPHIC
