December heating oil prices began the overnight session on a weak note but managed to rebound from an early test of yesterday's low. The outside market tone is supportive for heating oil prices this morning and Brent crude oil prices are up nearly $2.00 on the session. There have been some concerns over falling Midwest diesel prices as Gulf coast supplies have arrived in the region and there has been a boost in refinery activity. At least in the early morning action, December heating oil is choosing to look at outside markets for direction.
