   ACUS03 KWNS 181913 SWODY3 SPC AC 181912 Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0112 PM CST Thu Dec 18 2025 Valid 201200Z - 211200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms are possible across western Oregon and northern California late Saturday night. ...Synopsis... A broad cyclonic flow regime aloft will develop from the central into the eastern CONUS on Saturday, with an upper trough amplifying from the northern Plains into the Great Lakes. Gradual height rises will occur over the West, with weak flow aloft across the southern tier of states. Late in the period into Sunday morning, height falls will begin across the Pacific Northwest with an approaching wave. At the surface, high pressure will exist along the East Coast with southerly winds across the western Gulf and into the southern Plains. While some degree of low-level moisture return will occur, another cold front will push south across the Plains behind the developing Great Lakes system. As a result, any instability over coastal TX/LA should remain capped. Chances for thunderstorms will develop late in the period across the Pacific Northwest as a plume of midlevel moisture arrives out of the west. This moistening and warming in the 850-700 mb layer will result in weak elevated instability sufficient for isolated lightning. ..Jewell.. 12/18/2025 $$ |
