THE MORE SUBSTANTIAL BAND OF DEEP LAYERED CLOUDS WAS LOCATED WITHIN 75 MILES OF THE CURVE FROM 25N 180 TO 28N 173W TO 30N 164W AND FURTHER WEST AND NORTHEAST. THE MORE BROKEN-UP BAND OF LOW TO MIDDLE CLOUD LAYERS AND STRATOCUMULUS FRAGMENTS WITH A FEW TOWERING CUMULI EMBEDDED NEAR 30N WAS LOCATED WITHIN 75 MILES OF THE CURVE FROM 17N 180W TO 19N 174W TO 23N 173W TO 30N 159W AND FURTHER NORTHEAST. THESE FEATURES SHIFTED EAST SLOWLY. LOOSELY PACKED COLD-AIR CUMULI PREVAILED BETWEEN THE NORTHERNMOST BAND AND 30N. TO THE SOUTH...THERE WAS LITTLE THUNDERSTORM ACTIVITY TO MARK AN ITCZ. LAYERED LOW TO MIDDLE DEBRIS CLOUDS FROM EARLIER CONVECTION MOSTLY OBSCURED LOWER FEATURES BETWEEN 08N AND 02N. HOWEVER... ISOLATED THUNDERSTORMS AND THEIR DEEP LAYERED DEBRIS CLOUDS ASSOCIATED WITH A TROUGH OF LOW PRESSURE OCCURRED WITHIN THE AREA BOUNDED BY THE CURVE FROM 14N 163W TO 10N 158W TO 08N 159W TO 04N 174W TO 08N 176W TO 12N 168W. THIN LAYERED HIGH TO MIDDLE CLOUD LAYERS FOLLOWING A JET STREAM NORTHEAST FROM THOSE THUNDERSTORMS...TOGETHER WITH SOMEWHAT MORE SUBSTANTIAL CLOUD LAYERS FORMING IN ASSOCIATION WITH A WEAK TROUGH OF LOW PRESSURE IN THE MIDDLE ATMOSPHERE...MOSTLY TO PARTLY OBSCURED LOWER FEATURES WITHIN 100 MILES OF THE LINE FROM 19N 166W TO 12N 163W...AND NORTH OF THE CURVE FROM 30N 158W TO 22N 166W TO 22N 157W TO 25N 140W. LOWER IN THE ATMOSPHERE...A LAYER OF MARINE STRATUS MOVING IN FROM THE NORTHEAST BROKE UP INTO FRAGMENTS AND BANDS OF MARINE CUMULUS AND STRATOCUMULUS IN THE CORNER NORTH OF 10N AND EAST OF 160W... THOUGH THE SOLID OVERCAST WAS LIMITED MOSTLY TO NORTH OF 17N AND EAST OF 150W. THESE CLOUDS GENERALLY MOVED TOWARD THE WEST SOUTHWEST AT 15 TO 20 MILES AN HOUR...AND ROSE TO HEIGHTS OF 6000 TO 9000 FEET...THOUGH A FEW TOWERING CUMULI ALONG THE SOUTHWEST EDGE OF THIS AREA APPROACHED 22000 FEET. ACROSS THE MAIN HAWAIIAN ISLANDS...HIGH TO MIDDLE CLOUD LAYERS OBSCURED LOWER FEATURES MOSTLY OVER KAUAI COUNTY...AND PARTLY OVER OAHU. WHERE THEY WERE VISIBLE...LOWER CLOUDS CONSISTED MAINLY OF MARINE CUMULI AND STRATOCUMULI MOVING ASHORE ALONG SLOPES FACING EAST...ESPECIALLY ON MAUI AND THE BIG ISLAND. A FEW REMNANTS OF LAYERED DEBRIS CLOUDS FROM DAYTIME CUMULUS BUILDUPS ON WEDNESDAY STILL LANGUISHED IN PLACES...MOSTLY ALONG LOWER WEST SLOPES OF THE BIG ISLAND. THESE LOWER CLOUDS GENERALLY ROSE TO HEIGHTS OF 6000 TO 9000 FEET. RADAR DATA FROM NEAR THE ISLANDS SHOWED SCATTERED SHOWERS OVER THE KOOLAU RANGE ON OAHU...ALONG THE SOUTHEAST COAST OF THE BIG ISLAND...AND OFFSHORE TO THE NORTH OF MOLOKAI....BUT ISOLATED 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.
