PHOENIX -- The Valley’s streak of 80-degree temperatures continues into Monday, but newly formed tropical system ‘Octave’ could have an impact on Arizona down the road.

High pressure off the west coast continues to pump a warm air mass into Arizona. This is keeping temperatures about five degrees cooler than normal for this time of year.

Phoenix reached a high of 86 Sunday afternoon. Seasonal average for this time of year is 90. Monday morning, expect a low of 61 in Phoenix with an afternoon high of 85. The mid 80s will return each afternoon through next Sunday, with overnight lows in the upper 50s and low 60s.

Meanwhile, a low pressure system is brushing mostly north of Arizona as it tracks eastward. This is creating some locally breezy winds, especially in the high country. The speeds should not be strong enough to reach advisory criteria and should subside Monday.

Early Sunday, tropical storm Octave formed several hundred miles southwest of the Baja Peninsula.

As of Sunday afternoon, it had sustained winds of 65 miles per hour. It’s expected to make landfall in Mexico Wednesday as a tropical depression. Until then, Octave is streaming some moisture across southern Arizona, New Mexico and Texas.

As for now, forecasting models indicate storm development in Arizona from this topical moisture is very slim, however it’s not entirely out of the question. The 3TV forecasters will continue to keep a close eye on Octave in the coming days.
