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, will have to minor to potentiall PM thundershowers later in the week. Temperatures will remain above average through next weekend, with dry conditions currently expected.
