Several thunderstorms, some quite intense, emerged over the Northland this afternoon due to an upper-level trough and colder temperatures aloft, with 500mb temperatures dropping to -20 to -21C. Lapse rates also increased to approximately 7.0-8.0 C/km. These conditions, coupled with warmer surface temperatures, led to heightened instability and the development of scattered thunderstorms. Some storms produced small hail, measuring between 0.25 inch and 0.75 inch, accompanied by gusty winds reaching up to 50 mph.
