Thermometers soared to record levels on the Saturday most will remember as the quintessence of Winter 2006/2007.

The interesting thing about this event is that the record high temperature was broken at 7am in the morning. We reached 67° in the afternoon, smashing the old record by 14°! The old record for the maximum daily high temperature was 53°, set back in 1949. This was also the warmest day ever recorded in January in Portland. The day was warm from end to end, with the Portland JetPort recording a new record warmest low temperature of 48°. This also ties 1950 as first place for warmest low temperature for a day ever recorded in January in Portland. If you average the high and low temperature, you get the daily average temperature. And Portland broke that record too! We set several new average temperature records: 1) Daily average temperature for today's date was 43° and the normal is 22° - the new record is an astounding 58°; 2) Warmest daily average temperature for any day in January- the old record was 56° on January 4th, the new record is the 58°.
Another very interesting part of this event is that when compared to the climate normals, the daily average temperature from this day exceeded the running average by more than any other record... We exceeded the normal daily average by 36°! The old record for this was set back in January 4, 1950 when our daily average temperature exceeded the average by 33°.
Rain showers were falling in the morning and then the occlusion came on through the area. This resulted in high dewpoints across the area (into the 50s!) and when the breaks of sun arrived behind the front, the temperatures soared. Clearing arrived in the Portland area and held through until the 'cold' front came through that evening. Many areas were still into the 60s (with isolated low 70s) and the frontal passage kicked up some low-topped thunderstorms. There were reports of downed trees in Coos County in New Hampshire and gusts to about 50 mph in the Oxford Hills. Portland had mostly just a quick shot of heavy rain. These storms triggered the EAS with Severe Thunderstorm Warnings issued for Oxford, Franklin, Somerset and a few other counties. So not only was this day more summer-like than winter-like insofar as temperatures, but to have a severe thunderstorm warning in Maine in January makes this up to now a rare event.
Side note: Just two days later, areas like Fryeburg and Berlin, NH who were in the low to mid 60s got several inches of snow. This is a change from temperatures in the 60s to snow in just over 36 hours.
