The recent stretch of weather is quite unusual. High temperatures are averaging in the 70s with overnight lows in the 50s. This type of weather is more common in late August and early September than the middle of October. While it's not unusual to see this type of weather show up, keeping it around is very unusual. The weather looks to stay very mild here through the rest of the week.
In addition to the warmth, there's been a lack of a killing frost across the region. By now, the majority of Central New York has seen at least one frost. The average frost date for the Adirondacks is the third week of September. Outlying areas see frost the last week of September, and frost is common the first week of October in the Mohawk Valley. We're not only behind in the Mohawk Valley, but also in those cooler spots. This means a longer growing season, along with a longer insect season.
The weather is expected to change on Saturday, as a strong cold front approaches the region. Temperatures will drop from 70s to 50s by Sunday.
