The weather forecast undershot this one. Heading for -24 tonight and high of -10 tomorrow. Clouds of blowing snow pushed by ferocious NW winds were the excitement of the day. Those Alberta Clippers have a bite. Glad I fired the boiler this morning and early afternoon. 800 gallons of storage was at 150-165 at 5:00 pm when the boiler shut down. It will be a warm night.
