Weather Bureau Chief Explains Long Heat Wave.

Chief Willis L. Moore, of the government weather bureau at Washington has issued a signed statement explaining the cause for the hot wave of the past ten days and telling why he befieves more or less permanent relief is at hand. “For a prolonged period,” says the chief, “the barometric pressure has been above normal over the Atlantic Ocean and low over the northwestern portion of the American continent. The international weather map of Wednesday showed a reversal of this pressure distribution—an extensive area of high barometric pressure appearing over Alaska, while the pressure over the middle latitudes of the Atlantic Ocean has fallen to below normal. This changed pressure distribution is strong, indicative of the dissipation of the warm weather over the Eastern states and jn the middle West in the immediate future, and a period of moderate temperature in these districts lasting through the remainder of this week and continuing into next week.” Lower temperatures were reported from almost all points Wednesday.
