TUCSON - The first taste of fall is just a day away from southern Arizona.
High pressure keeping highs in the 90s for the first part of October will give way to much cooler weather as soon as tomorrow, according to Meteorologist John Patrick. A Pacific low inches closer to Arizona tomorrow knocking the temperatures down into the mid 80s for daytime highs.
The approaching front kicks up the winds into the 15-25mph range out of SSW tomorrow afternoon. Winds should stay below advisory criteria but some patchy blowing dust may be possible near the problem areas along I-10.
Rain chances come as soon as tomorrow afternoon and evening and stick around through the overnight hours. The heaviest precipitation looks to stay in northern Arizona with this system but some valley locations could pick up 0.10"-0.25" with heavier amounts in thunderstorms.
General clearing is expected throughout Friday afternoon as rain tapers off from the southwest to the northeast. Friday afternoon looks beautiful with highs in the mid 70s for Tucson, temperatures we haven't seen since April.
A warm up starts this weekend as an area of high pressure starts to build back into the region. At least we'll keep it below average both Saturday and Sunday with highs in the low to mid 80s, however, the 90s return early next week.
