High pressure over Arizona will support above-normal temperatures with a south to southwesterly flow drawing remnant moisture from Iselle in the Eastern Pacific northward across the area, making for a very tropical environment with enough mid-level instability for a few showers and thunderstorms at times, mainly during the afternoons. Continued warm with highs in the mid-80s today and tommorrow, while overnights cool to the 50s and 60s. High pressure will shift further east this weekend as a trough of low pressure develops off the West Coast producing gusty west winds 15-25 mph at times. This will lead to cooler temperatures next week as temperatures return to normal. The southwest flow aloft may also draw additional moisture into the region for a chance of showers and thunderstorms across all areas towards the middle of next week, but the extent of moisture and instability for SoCal is unknown at this time. This will be an increasing risk over the next month or so, with an active hurricane season in the Pacific and troughing that develops along the West Coast this time of year.
