THIS FEATURE CONSISTED MOSTLY OF DENSE LOW TO MIDDLE CLOUD LAYERS FRAGMENTING INTO MARINE STRATOCUMULI. CLOUD COVER NORTHWEST OF THIS BAND CONSISTED MAINLY OF COLD-AIR CUMULI...THOUGH STREAKS OF THIN HIGH CLOUD LAYERS PASSED ON A JET STREAM OVERHEAD. A NEARLY STATIONARY BAND OF DEEP LAYERED CLOUDS PRECEDED THE MAIN FRONTAL CLOUD BAND NORTH OF THE CURVE FROM 30N 162W TO 24N 162W TO 19N 164W TO 18N 163W TO 27N 156W TO 30N 156W. SCATTERED EMBEDDED TOWERING CUMULI AND PROBABLE THUNDERSTORMS ROSE THROUGH THE SURROUNDING CLOUD LAYERS. WATER VAPOR IMAGES SHOWED AN AREA OF LOW PRESSURE IN THE UPPER ATMOSPHERE TO THE NORTHEAST OF THE MAIN HAWAIIAN ISLANDS. LAYERED HIGH TO MIDDLE CLOUDS WRAPPING COUNTER-CLOCKWISE AROUND THIS FEATURE PARTLY TO MOSTLY OBSCURED LOWER FEATURES NORTHEAST OF THE CURVE FROM 30N 143W TO 28N 144W TO 26N 143W TO 28N 140W. TO THE SOUTH...LIGHT THUNDERSTORM ACTIVITY CONTINUED IN THE ITCZ BETWEEN 12N AND 07N...MOSTLY EAST OF 154W. LAYERED MIDDLE TO HIGH DEBRIS CLOUDS FROM THIS AND EARLIER CONVECTION MOSTLY TO COMPLETELY OBSCURED LOWER FEATURES EAST OF THE CURVE FROM 22N 140W TO 09N 154W TO 08N 146W TO 11N 140W. OTHERWISE...CLOUD COVER ACROSS HAWAIIAN WATERS CONSISTED MAINLY OF A LAYER OF MARINE STRATUS BREAKING UP INTO STRATOCUMULI AS IT APPROACHED FROM THE NORTHEAST. THE NEARLY SOLID OVERCAST WAS LIMITED TO NORTHEAST OF THE CURVE FROM 30N 147W TO 25N 144W TO 23N 140W... BUT ARCS OF STRATOCUMULI REACHED AS FAR SOUTHWEST AS THE CURVE FROM 30N 156W TO 24N 151W TO 16N 145W TO 18N 140W. INDIVIDUAL STRATOCUMULUS AND CUMULUS FRAGMENTS OCCURRED FURTHER SOUTHWEST AS WELL. THESE CLOUDS GENERALLY ROSE TO HEIGHTS OF 6000 TO 9000 FEET... AND MOVED TOWARD THE WEST SOUTHWEST AT AROUND 15 MILES AN HOUR. ACROSS THE MAIN HAWAIIAN ISLANDS...MIDDLE TO HIGH CLOUD LAYERS ASSOCIATED WITH THE FRONTAL CLOUD BAND PARTLY OBSCURED KAUAI COUNTY AND OAHU. OTHERWISE...CLOUD COVER CONSISTED MOSTLY OF MARINE CUMULI AND STRATOCUMULI MOVING ASHORE ALONG SLOPES FACING NORTHEAST... THOUGH LAYERED DEBRIS CLOUDS FROM AFTERNOON CUMULUS BUILDUPS OVER HIGHER TERRAIN ON TUESDAY STILL LINGERED IN PLACES...ESPECIALLY ALONG LOWER TO MIDDLE SLOPES OF SOUTH KOHALA DISTRICT ON THE BIG ISLAND. THESE LOWER CLOUDS GENERALLY ROSE TO HEIGHTS OF 6000 TO 8000 FEET. RADAR DATA FROM NEAR THE ISLANDS SHOWED SCATTERED SHOWERS OVER THE EAST TIP OF MAUI...AND INDIVIDUAL HEAVY SHOWERS OFFSHORE TO THE SOUTHWEST OF NIIHAU AND SOUTHEAST OF THE BIG ISLAND...BUT ISOLATED LIGHT SHOWERS AT MOST ELSEWHERE. $$ RYSHKO +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
