PHOENIX -- A partly sunny, warm and dry day is expected in the Valley with an afternoon high around 103 degrees.
An Ozone Health Watch is in effect for the Valley today. People with a sensitive respiratory system, including people with asthma, are urged to limit their time outside today. Everyone can help out by limiting driving or carpooling, avoiding gas-powered equipment and refueling after dark.
A few clouds are expected today and tomorrow, but dry and warm conditions are expected still before a strong early fall storm moves our way from the Pacific. Rain chances start Friday night in the Valley and increase during the day on Saturday.
Rainfall totals between a quarter of an inch and an inch are possible in the Valley, with higher amounts expected in the mountains of the state.
Thunderstorms including strong winds and hail are possible Saturday, too.
Behind the cold front, Sunday looks much cooler, and that cool air sticks around into the middle of next week.
Highs from Sunday through Wednesday range from the upper 80s to low 90s and overnight lows fall to the 60s.
