The atmospheric set up at the height of the outbreak – 18:00 on 27 October.

A rapidly deepening low-pressure extratropical cyclone tracked quickly south on the afternoon of 27 October. The central pressure of the system was Шаблон:Convert at midnight on the 27th, deepening to Шаблон:Convert by 18:00. The low pressure helped to sustain a stream of strong southerly winds, as in days previous, sustaining significantly warmer than average conditions.

The low pressure brought cooler air to the country by the 31st.
