Here in the November chart you can see how the month began quite warm before dropping into the moderate normal range. If you notice the colder blue portion showing minimums down to their record lows you can see an overall trend that we often experience that causes us consternation and can put certain of our plants under considerable stress. It shows two ranges of quite cold lows, with records well below the norm. These sudden temperature drops can do considerable freeze damage to many plants that may have ‘sailed’ through on mild Fall temps only to get ‘hammered’.
