(Reuters) - Cotton futures rose on Wednesday supported by concerns that dry weather in West Texas, the largest U.S cotton-producing region, may weigh on U.S supplies of the crop.

* Cotton contracts for May  rose 0.54 cent or 0.7% to 79.76 cents per lb by 2:10 p.m EDT (1810 GMT). It traded within a range of 78.84 cents and 80.64 cents a lb.

* The market is likely waiting for some further developments with cotton planting and weather, especially in West Texas, said Jon Marcus, president of Lakefront Futures and Options brokerage in Chicago.

* "You are basically seeing some consolidation (in cotton) ... until we settle over about 81.05 cents in that market - you'll probably see lower to sideways trade," Marcus added.

* Also boosting sentiment for cotton were gains in the U.S. corn and soybean markets.

* "The May (cotton) contract should experience resistance near 81.00-82.00 and support near 77.00–78.00 over the near- to medium-term," Louis Rose, director of research and analytics at Tennessee-based Rose Commodity Group, said in a note.

* Increased volatility and drought conditions in Texas could move December cotton futures into the high 80s or low 90s, Rose added.

* Total futures market volume fell by 13,874 to 34,965 lots. Data showed total open interest gained 985 to 229,592 contracts in the previous session.
