Looking at a gorgeous weekend out there with near-normal temperatures and dry conditions for our last day of spring, summer officially arrives tomorrow at 1:24 AM. Expect mostly sunny skies today with highs in the mid to upper 70s, west winds 5-15 mph during the afternoon. Clear tonight with light winds as lows cool to the mid 40s. Little change for Father's Day with highs in the 70s, west winds 5-10 mph at times. High pressure will strengthen across the region through next week, leading to our first summer heatwave as temperatures reach the mid-80s by midweek. Forecast models are also hinting at an increase in monsoon moisture from the south, which should bring at least some afternoon clouds, a few thundershowers cannot be ruled out later in the week. Temperatures will remain above average through next weekend, with dry conditions currently expected.
