Abstract : This study is a continuation of a summertime stratus study completed in 1953. In this study an attempt is made to determine a quantitative relationship between the strength of the flow, as determined by selected pressure differences, and the occurrence of cloudiness and ceiling heights at McChord AFB, Washington. The purpose of this study is to make available at 1300P daily an objective forecast giving the probability of occurrence of the ceiling category for McChord AFB between 2200P that night and 1200P the following day. The data used was North Bend-Seattle and Portland-Seattle pressure differences at 1300P for June, July and August, 1958 through 1963 as dependent data, and the same months for 1964 as independent data.
