Indian Summer

Through most of Autumn we've seen above normal temperatures, with many saying it was an "Indian Summer", but was it?

First we have to look at the definition of an Indian Summer; this happens when we see a period of above normal warm weather, after we see the first killing freeze of autumn.
A killing freeze is defined when temperatures reach 28° or less for the first time in the growing season. We didn't see the killing freeze until October 17th, this is when our minimum temperature reached 28°. So any warmth before that time in autumn, wasn't considered an 'Indian Summer.' Temperatures were very warm October 19th-21st, with highs in the mid 70's. This period could also be thought of as an Indian Summer. Overall the month of October was very warm, the month ended up being 2.4° above normal. This week is also the definition of an Indian Summer, as temperatures will be about 10-15° above normal. There can be more than one 'Indian Summer' in one season. Monday, Tuesday, and Wednesday all look to stay in the low 70's, however cloud cover could impact temperatures a bit. Overall, temperatures will be very mild going forward through midweek, but we return to more seasonable temperatures by the end of the week.
