An upper-level ridge remained over the region keeping temperatures warm and conditions dry on Saturday, and this will remain through Sunday morning before a surface cold front associated with an upper-level trough from the Pacific Northwest begins to move through the area Sunday afternoon.
Expect windy conditions up to 55 mph along the Rocky Mountain Front and adjacent plains. As a result, on Sunday there is a High Wind Watch in effect for the Rocky Mountain Front over to Liberty County from 3 PM to Midnight.
