WEST OF 173W. THESE CLOUDS EXTEND UP TO 30000 FT.

AN UPPER LEVEL JET STREAM IS LOCATED SOUTH OF THE LOW. AN AREA OF
CIRRUS AND CIRROSTRATUS CLOUDS ASSOCIATED WITH THE JET IS GREATEST
IN COVERAGE BETWEEN 15N AND 20N WEST OF 150W. AREAS OF HIGH CLOUDS
ARE LOCATED FARTHER SOUTH, AND PATCHES OF THIN CIRRUS ARE LOCATED
FARTHER NORTH, COVERING A PORTION OF THE STATE. THESE HIGH CLOUDS
ARE MOVING TO THE EAST-NORTHEAST AT 40 TO 60 MPH.

FLOW ARE THE MAIN CLOUD FEATURES. THESE CLOUDS ARE GREATEST IN
COVERAGE EAST OF 150W, AND ALSO NORTH OF 26N WEST OF 150W, THOUGH
COVERAGE HAS DIMINISHED SINCE THIS MORNING. THE CLOUDS ARE
