NEW YORK, Nov 19 (Reuters) - U.S. crude oil futures fell Thursday on the dollar's strength, slumping equities and continued concern about demand. "Wall Street had a weak opening, which added to the pressure on crude from the dollar's moving up some," said Tom Bentz, analyst at BNP Paribas Commodity Futures Inc in New York. Bentz and other sources also noted the government forecast for December temperatures to have equal chance of being above or below average in the U.S. Northeast and above average temperatures for the Midwest and Great Lakes. The dollar and the yen rose as equity and commodity markets fell, encouraging investors to pare back exposure to perceived riskier currencies. [USD/] U.S. stocks fell more than 1 percent shortly after the open after a bearish analyst comment on semiconductor stocks, even as data showed no change in weekly jobless claims.
