DISCUSSION

Issued at 119 AM CST Sun Jan 11 2026

Northwest flow aloft will be the prevailing feature of the upper- level weather pattern this week. A cutoff low pressure system over the Baja Peninsula will shear out and become absorbed in the flow aloft, setting up a more traditional positive PNA pattern over the CONUS by mid week. The anomalously strong ridge will anchor over the West Coast while a trough deepens over the eastern CONUS and comes to dominate the central CONUS by late week. This flow will reinforce cooler air across our region throughout the week and prevent substantial moisture return until next weekend. Light rain is possible around Wednesday as the remnants of the cutoff low pass through the region, but confidence isn't high for accumulations. While some model guidance hint at some potential for wintry precip around the region, the details don't support much chance for meaningful moisture to coincide with air that might be cold enough. The pattern is less certain next weekend, but some chance for better rainfall could develop depending on how the trough sets up. /NF/
