* Front month remains above recent four-month spot low * Above-normal temperatures still on tap for both coasts * Nuclear plant outages continue above average By Eileen Houlihan NEW YORK, July 5 (Reuters) - U.S. natural gas futures fell more than 2 percent early on Friday in quiet post-holiday trade despite above-normal nuclear power plant outages and forecasts for heat in consuming regions in the Northeast in the coming days. Traders said many offices remained shut on Friday or had skeleton crews after closing on Thursday for the U.S. Independence Day holiday. Milder weather in consuming regions and healthy inventories should help limit near-term gains, traders said, despite a slew of 90 degree (Fahrenheit) temperatures expected for key Northeast cities over the next few days that should stir demand for air conditioning. As of 9:18 a.m. EDT (1318 GMT), front-month August natural gas futures on the New York Mercantile Exchange were at $3.601 per million British thermal units, down 8.9 cents, or more than 2 percent. The contract rose in the prior three sessions, boosted by the hotter weather outlook. The latest National Weather Service six- to 10-day forecast, issued on Thursday, called for above-normal temperatures for about the western third of the nation and along much of the East Coast, with normal or below-normal readings in the middle of the nation. Wednesday's gas storage report from the U.S. Energy Information Administration, issued a day early this week due to the holiday on Thursday, showed total domestic inventories rose last week by 72 billion cubic feet, in line with Reuters poll estimates for a 71 bcf build and the five-year average build of 71 bcf for that week. Total gas inventories at 2.605 trillion cubic feet are about 16 percent below last year's record high level, but only 1 percent below the five-year average level. Early injection estimates for next week's storage report range from 82 bcf to 102 bcf, versus a 34 bcf build during the same week last year and a five-year average increase for that week of 74 bcf. Nuclear plant outages on Friday totaled 5,800 megawatts, or 6 percent of U.S. capacity, even with Wednesday's outages, down from 9,300 MW out a year ago, but up from a five-year average outage rate of 4,900 MW. Baker Hughes data on Wednesday, also issued early this week due to the holiday, showed the gas drilling rig count rose for a second straight week, gaining 2 to 355, after posting an 18-year low of 349 three weeks ago.
