WEST OF THE RIDGE IS AN UPPER LEVEL TROUGH WITH A CENTER AXIS FROM 40N174E TO 21N179W. THIS UPPER LEVEL TROUGH IS PRODUCING A LARGE AREA OF MULTILAYERED CLOUDS 400 TO 500 MILES WIDE ALONG AN AXIS FROM 30N180 TO 36N175W TO 32N168W TO 21N174W TO 13M175E. ISOLATED CUMULONIMBUS CLOUDS WITH TOPS TO 50 KFT ARE EMBEDDED WITHIN THE CLOUD BAND. WHILE MOST OF THIS THUNDERSTORM ACTIVITY IS SOUTH OF 24N...A FEW POPPING TOWERING CUMULUS /TCU/ CLOUDS ARE LOCATED ON THE COLD SIDE OF THE SURFACE LOW WHICH IS CENTERED AT 29N177W. THE TCU CLOUDS ARE CONTAINED WITHIN A 150 MILE RADIUS OF THE SURFACE LOW. A COLD FRONT IS BURIED BENEATH THE UPPER LEVEL CLOUD FEATURES EXTENDING SOUTHWEST FROM THE SURFACE LOW CENTER TO 24N180 TO 21N173E. A FEW LOW CLOUDS ARE ASSOCIATED WITH THE BOUNDARY AS IT LAGS BEHIND THE DENSE LAYERED CLOUD BAND. A STATIONARY FRONT ALSO EXTENDS EAST FROM THE LOW TO 31N147W. A BROAD LINE OF LAYERED CLOUDS ASSOCIATED WITH A 150 MPH JET STREAK ORIENTED WEST TO EAST. THE JET HAS AN AXIS FROM 30N145W ALL THE WAY OVER THE WESTERN CONTINENTAL UNITED STATES. UNDERNEATH THE JET...SHORTWAVE ENERGY AT THE MIDLEVELS AS WELL AS THE STATIONARY FRONT LOW ARE PROVIDING CLOUDS BENEATH THE JET. MOST OF THIS DENSE CLOUD COVER IS LOCATED TO THE NORTH OF 29N. SCATTERED TO BROKEN CUMULUS CLOUDS COVER MUCH OF THE WINDWARD COASTAL WATERS OF THE MAIN HAWAIIAN ISLANDS THIS MORNING. THE CUMULUS CLOUDS ARE TRAVELING TO THE WEST-NORTHWEST AT 15 MPH. PLUME CLOUDS ARE OBSERVED ON INFRARED SATELLITE ACROSS LEEWARD WATERS OF THE ISLANDS. A FEW CLOUDS ARE REPORTED OVER LAND ACCORDING TO OBSERVATIONS AND INFRARED SATELLITE SUPPORTS THIS. FAR SOUTH OF THE HAWAIIAN ISLANDS...SCATTERED ITCZ CONVECTION IS FIRING MAINLY EAST OF 150W AND BETWEEN 06N AND 10N.
