September natural gas prices broke out to a three session high during the initial morning hours, helped by upside follow though action following yesterday's outside day reversal. The latest six to ten day weather maps show extreme heat coming back into the forecast, with above average temperatures across the Northeastern region into August 30th, and that is seen as a force lifting air-conditioning demand for natural gas. Tropical storm activity provides a measure of support, with the ninth tropical depression developing about 700 miles east of the Leeward Islands.
