March natural gas prices traded sharply lower during the early morning hours and established a lower low in the process. Some traders pointed to above average temperatures limiting heat-related demand in the face of abundant supplies as a key factor weighing on prices. Meanwhile, a longer term demand positive might have come yesterday after Clean Energy Fuels announced a deal with Navistar to make more natural gas vehicles and build more fueling stations. Expectations for this morning's EIA natural gas storage report are for a decline in the range of 120 to 125 bcf, which compares to last year's draw of 187 bcf.
