High pressure over the Desert Southwest will strengthen through the end of the week into the weekend, bringing another major heatwave with temperatures locally nearing 10 degrees above average. While we won't be excessively hot in the mtns, it will still be very warm where a heat advisory is in effect all the way through Monday. We also have lingering monsoon moisture that will bring a few afternoon clouds with an isolated shower or thunderstorm possible at times. Expect mostly clear skies this evening with lows in the 50s. Mostly sunny and warmer on Thursday with highs in the mid-80s, east winds 5-10 mph at times. Temperatures will increase Friday through the weekend as daytime highs top out in the upper 80s, while overnight temps also remain mild with lows in the 60s. Monsoon moisture will increase this weekend over Arizona, so we'll have to watch for any potential outflow or easterly wave sneaking into our area, which could trigger isolated convection. Expect more of the same throughout next week!
