SATELLITE DERIVED WINDS INDICATE A 75 MPH JET STREAK ON THE EASTERN FLANK OF THE TROUGH. AN ASSOCIATED SURFACE TROUGH HAS AN AXIS FROM 15N151W TO 10N155W. THIS SYSTEM IS PRODUCING AN AREA OF DENSE LAYERED CLOUDS WITH ISOLATED EMBEDDED CUMULONIMBUS /CB/ CLOUDS WITH TOPS TO 45 KFT. THE CLOUDS ARE BOUNDED BETWEEN 08N TO 16N AND TO 145W TO 155W AND HAS DECREASED IN AREAL COVERAGE OVER THE PAST SIX HOURS. CIRRUS CLOUDS FROM THE JET STREAM RUN TO THE NORTHEAST OF THIS BOUNDED AREA. AN AREA OF STRATUS AND STRATOCUMULUS CLOUDS ARE LOCATED OVER THE HAWAIIAN WINDWARD AND MAUKA AREAS AND ADJACENT COASTAL WATERS AND MOVING EAST TO WEST AT 10 TO 15 MPH. THESE CLOUDS ARE ASSOCIATED WITH WEAK DISTURBANCE PASSING ACROSS THE STATE EARLY THIS MORNING WHICH IS PRODUCING OCCASIONAL SHOWERS FOR THE WINDWARD SIDES OF THE ISLANDS. IR SATELLITE SHOWS MOST OF THE CLOUDS AND SHOWERS CONCENTRATED ACROSS THE SMALLER MAIN ISLANDS AT THIS TIME. THE CLOUDS EXTEND FROM THE ISLANDS NORTHWARD TO AROUND 27N AND ARE BOUNDED AT 155W TO THE EAST. ANOTHER BATCH OF MOISTURE BEGINS 30 MILES UPSTREAM OF THE BIG ISLAND IS MOVING FROM THE EAST TOWARDS THE WINDWARD SIDE. THIS AREA OF CLOSED CELL CUMULUS CLOUDS IS BOUNDED BETWEEN 20N TO 23N AND 138W TO 155W AND IS ALSO TRAVELING TO THE WEST AT 10 TO 15 MPH. FURTHER NORTH IS A STATIONARY FRONT IS POSITIONED ALONG AN AXIS FROM 38N140W TO 31N160W TO 37N178E AND IS CHARACTERIZED BY A 200 MILE WIDE BAND OF OVERCAST STRATUS CLOUDS. THE ASSOCIATED LONG WAVE UPPER TROUGH AND MID AND HIGH LEVEL MOISTURE IS PRODUCING AREAS OF LAYERED CLOUDS WITH TOPS AROUND 30 KFT. FAR SOUTH OF HAWAII IN THE ITCZ...THUNDERSTORMS HAVE DECREASED OVER THE LAST SIX HOURS. SCATTERED CB CLOUDS COVER AN AREA BETWEEN 06N AND 14N ALONG THE CENTRAL PACIFIC BASIN. CLOUD TOPS REACH TO 46 KFT IN HEIGHT. $$ FOSTER +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
