WHILE THE LAYERS COMPOSING THIS BAND STARTED TO SHEAR APART...MOVING AT DIFFERENT SPEEDS DEPENDING ON HEIGHT...THEY REMAINED FAIRLY DEEP AND DENSE. THIS FEATURE AS A WHOLE SHIFTED NORTH SLOWLY. CLOSER TO THE NORTHWEST...SCATTERED TOWERING CUMULI AND THUNDERSTORMS...AND THEIR LAYERED DEBRIS CLOUDS WITHIN 125 MILES OF THE LINE FROM 17N 180 TO 27N 158W...MARKED ANOTHER FRONT. THIS FEATURE REMAINED NEARLY STATIONARY. FURTHER NORTHWEST...DENSE LAYERED HIGH TO MIDDLE CLOUDS ASSOCIATED WITH A JET STREAM OBSCURED LOWER FEATURES NORTH OF THE CURVE FROM 30N 176W TO 23N 176W TO 26N 166W TO 30N 163W.

MARINE STRATOCUMULI AND LOW TO MIDDLE STRATUS LAYERS ORGANIZED INTO NOTICEABLE BANDS AS WIND CONVERGED SOUTHEAST OF THE FRONTS. ONE AREA OF CONVERGENCE WAS LOCATED WITHIN 150 MILES OF THE LINE FROM 17N 160W TO 29N 144W...EXCEPT FOR A GAP OVER THE BIG ISLAND. THE CLOUDS MAKING UP THIS FEATURE WERE FAIRLY WELL DEVELOPED...EVEN INCLUDING A THUNDERSTORM NEAR ITS SOUTHWEST END. A LESS DEVELOPED AREA OF CONVERGENCE WAS LOCATED WITHIN 150 MILES OF THE LINE FROM 13N 154W TO 22N 142W. THE CLOUDS COMPOSING THIS FEATURE WERE LESS DEVELOPED AND GENERALLY LOWER IN HEIGHT. OTHERWISE...CLOUD COVER ACROSS HAWAIIAN WATERS CONSISTED MAINLY OF FRAGMENTED MARINE STRATOCUMULI AND CUMULI. THESE CLOUDS GENERALLY MOVED TOWARD THE WEST AT 10 TO 15 MILES AN HOUR...THOUGH NEAR THE FRONTS THEY TURNED TOWARD THE NORTHWEST AND THEN THE NORTH. THEY TYPICALLY ROSE TO HEIGHTS OF 6000 TO 9000 FEET...THOUGH TALLER CUMULI APPROACHED 15000 FEET. ACROSS THE MAIN HAWAIIAN ISLANDS...CLOUD COVER CONSISTED MOSTLY OF A FEW SPARSE MARINE CUMULI MOVING ASHORE ALONG SLOPES FACING EAST. LAYERED DEBRIS CLOUDS FROM DAYTIME CUMULUS BUILDUPS ON TUESDAY HAD DISSIPATED FOR THE MOST PART. THESE CLOUDS GENERALLY ROSE TO HEIGHTS OF 4000 TO 5000 FEET. RADAR DATA FROM NEAR THE ISLANDS SHOWED ISOLATED SHOWERS AT MOST. $$ RYSHKO +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
