High pressure will slowly strengthen over the region this week, leading to above-normal temperatures with highs approaching 90 degrees by the middle of the week. High pressure overhead this week will slowly shift over the Four Corners later in the week, taking on more of an east-west orientation, which is a favorable position to draw monsoon moisture into the region. This could lead to some afternoon thundershowers over the weekend or early next week with cooler temps due to the increase in cloud cover and humidity. Expect mostly sunny skies today as highs top out in the lower to mid-80s, with west winds 5-10 mph during the afternoon. The warm-up will continue through the end of the week as daytime highs reach the mid to upper 80s Wednesday through Friday, while overnight lows cool to the 40s and 50s. An east-to-southeast flow will develop later this week, drawing mid & upper-level moisture into the region for a few high clouds and some afternoon build-ups. Deeper moisture and better instability could arrive over the weekend, with afternoon thundershowers possible by next week.
