Precipitation is expected to exceed normal in the Northeast as well as over the central and north Pacific coast. Subnormal amounts are indicated for the southern Plateau, and from the Rockies to the Appalachians except for near normal totals in the southern Plateau, the gulf coast, and Great Lakes regions. Elsewhere near normal precipitation is in prospect. Weather forecast given here is based on the official 30-day "Resume and Qutlook" published twice a month by the Weather Bureau.
