A few clouds and high pollen counts aside, we tacked on another winner to close out the work week. Those of you who want this to carry over to the weekend get your wish. Saturday is also exceptionally nice, though tending more summery than springlike. Sunday isn’t too shabby either, although clouds may build late.
