TUCSON - Fall is officially underway as of 7:49am this morning but it's certainly not going to feel like it.
We bring in the fall season with our 72nd day at or above 100 for Tucson, according to Meteorologist John Patrick. High pressure holds strong to keep daytime highs nearly ten degrees above average through the weekend. High will hover between 100-103 for the first weekend of fall with overnight lows dipping into the 60s and 70s. Mostly sunny skies will prevail with a few cumulus cloud build-ups possible over the higher elevations.
An upper level low approaches the west coast to start off the work week bringing some cooler temperatures to the region. This system will keep the precipitation off to our north but a gradual cool down will start Monday. A high near 96 is forecast for Monday and temperatures slowly drop from there wrapping up the work week with highs in the upper 80s.
