Forecaster:  Henz, D.


Happy October 1st and the beginning of Water Year 2015! A final word on last month, September 2014 went down as the second wettest for Phoenix Sky Harbor Airport with 5.11” of rain (courtesy of the NWS Phoenix WFO). The forecast from yesterday remains on track for today as a weak disturbance is progged to move southeast across the Great Basin/Northern AZ today bringing only some increased gusts to the region. Dry northwesterly flow aloft will remain in place through the remainder of the week to go along with redevelopment of high pressure over the Desert Southwest meaning quiet weather and a steady warming of temperatures into this weekend.


For today plan on mainly clear skies as afternoon temperatures climb into the 89˚F-93˚F range around the Valley with higher terrain areas limited to the mid to upper 80s. Variable winds will generally remain in the 4-10mph range with occasional afternoon/evening gusts approaching 15-20mph. Overnight lows will dip into the low 70s around the urban corridor with upper to mid 60s in outlying communities under clear skies and light northeasterly winds.


For tomorrow plan on another healthy dosing of sun around the region. Daytime temperatures will climb into the low to mid 90s around the Valley. Variable winds will remain in the light category with no gusts of any consequence expected. A modest warming trend really gets going Friday with developing high pressure over the region. Temperatures should warm another few degrees into the mid to upper 90s before possibly reaching the 100F mark on Saturday (likely the warmest day of the week).
