As high pressure slowly rebuilds this week, temperatures will climb, with our first heat wave of the summer in store for us by weeks' end; monsoon moisture will stay south of the area for the time being. Expect clear blue skies through Tuesday, warmer too with highs back in the mid to even upper 70's; southwest winds 5-15mph at times. More noticeable warming arrives Wednesday through Friday, when daytime temps reach well into the 80's, Thursday will likely be the warmest day of the week, right on cue, summer begins early Thursday morning. High pressure will weaken just a tad over the weekend, allowing temperatures to return to normal (76/40), before high pressure expands back into the region next week, bringing another warm-up with very dry, summer conditions forecast for a while.
