Weekend Weather USA: December 2025 Forecast Shows Warm
As the final weekend before Christmas arrives on December 20-21, 2025, the United States is experiencing a sharp weather divide. Following early December’s arctic outbreaks and snow, a major pattern shift has brought unseasonably warm temperatures to much of the central, southern, and eastern regions. In contrast, the West Coast, particularly California, is dealing with ongoing heavy rainfall from atmospheric rivers, raising concerns for flooding. This USA weekend weather forecast will help with holiday planning, travel, and outdoor activities.
National Overview
Above-average temperatures dominate much of the country this weekend, with record warmth possible in the Southwest, Texas, and parts of the Plains. Highs could be 20-30 degrees above normal in some areas, leading to rapid snow melt from earlier storms. Dry conditions prevail east of the Rockies, while the Pacific Northwest and California see persistent precipitation, including heavy rain and mountain snow. No widespread severe winter weather is expected in the East.
