PHOENIX -- High pressure building into the region will kick off a warming trend in the Valley with temperatures returning to the mid 90s.
Meanwhile, freezing overnight temperatures in the high country are allowing leaves to change into vibrant fall colors.
A cold front that swept across Arizona late last week, kicked up breezy northeasterly winds Saturday. Those winds are expected to lighten up moving into part two of the weekend.
Cooler air also filtered into the region Saturday afternoon, preventing Valley highs from escaping the 80s, but the 90s are on tap for Sunday and into the first half of the week as high pressure takes over.
Saturday night in Phoenix, expect a low of 60, with a high of 92 Sunday. Lows will remain in the 60s through Wednesday night. Temperatures in the Valley will peak Tuesday with a high of 94 for Phoenix.
In northern Arizona, overnight lows in the 20s and 30s with daily sunshine and highs ranging from the 50s to 60s has turned leaves into yellows, reds and oranges. According to John Brice with Arizona Snowbowl, aspen leaves are at their peak. Approximated 50 percent of tree canopy in the Flagstaff area has turned color. Brice said the next two weeks will be prime time to view the color change.
Last week, Arizona Snowbowl announced they’d expand their scenic chairlift operations for leaf-peepers in the wake of national park closures due to the government shutdown.
