High pressure over the area will lead to above-normal temperatures this week, with a slight chance of afternoon showers or thunderstorms at times. A heat advisory remains in effect through Tuesday, which will likely be extended throughout the week, while an extreme heat watch remains in effect for areas below 5,000 feet. Expect partly cloudy skies on Monday with highs in the mid 80s, southwest winds 5-10 mph during the afternoon. Little change throughout the week, with some warming by Wednesday and Thursday as highs reach the mid to upper 80s, with overnight lows generally in the 50s. High pressure will meander over Arizona much of the week, with a weak southerly flow drawing limited monsoon moisture into the region. Moisture and instability will increase a bit early in the week with a chance for an afternoon thundershower Monday and Tuesday, then possibly again later in the week.
