A few showers could move into the far west by Thursday morning. Cold front moves across the area on Friday...with QPF amounts of .50 inches or less. Not expecting severe weather with this front. Models still showing large scale flow to be less amplified and more zonal in a front not likely to slow down quite as much for late Friday into Sat. Adjusted ending time some...sooner Friday Night. Still looks like a dry day on Saturday. More showers for Sunday into a jet max moves across the area. Starting to see signs that dry intrusion and dynamics could support not only thunder...but even strong storms. Cooler and drier conditions for late Tuesday into Wed. Overall a trend toward a cooler and wetter a ridge builds across the west.
