The urban heat island might be done with 32 or below, out here though it's usually a few degrees colder or more than the city at night. And like PSV said, lots of blooming here over the last week. Hopefully the cold air sets up west of us like usual again so we don't see plant damage. Of course I'd be more than happy to keep the bugs away a few more weeks. With all this rain the mosquitoes will be awful later in the spring.
