Enjoyed a gorgeous Independence holiday weekend with seasonal weather and dry conditions. High pressure will slowly build over the area, leading to warmer temperatures as we experience our 2nd heatwave of the summer season, with temperatures possibly approaching 90 degrees by the middle of the week. High pressure overhead this week will slowly shift into the Four Corners region towards the end of the week, taking on more of an east-west orientation, which is more favorable to draw monsoon moisture into the region. This could lead to some afternoon thundershowers by the weekend with cooler temps due to the increase in cloud cover and humidity. Expect mostly clear skies through Monday as highs top out around 80 degrees once again with west to northwest winds 5-10 mph. As the warm-up progresses throughout the week, daytime highs will reach the mid to upper 80s by Wednesday, while overnight lows cool to the 40s and 50s. As an east-to-southeast flow develops later in the week, we'll begin to see some afternoon build-ups, which could generate a few thundershowers over the weekend into next week.
