THE SOURCE OF THE CIRRUS IS FROM THUNDERSTORM ACTIVITY IN THE WAKE ISLAND AND KWAJALEIN AREA LOCATED 2100 MILES WEST SOUTHWEST OF KAUAI. THE WIDTH OF THE CIRRUS BAND IS 300 MILES WIDE. THE SOUTHWEST WIND FLOW HIGH ABOVE THE HAWAIIAN SKIES IS MADE POSSIBLE BY AN UPPER LEVEL LOW AND ASSOCIATED TROUGHS LOCATED WEST OF THE MAIN HAWAIIAN ISLANDS. THE UPPER LOW IS NEAR 28N167W OR 520 MILES NORTHWEST OF KAUAI. A TROUGH EXTENDS SOUTHWARD FROM THE LOW AND THE OTHER TOWARD THE NORTHEAST. THE UPPER LOW NORTHEAST OF KAUAI HAS BEEN INCHING SOUTHEASTWARD DURING THE COURSE OF THE EVENING AND IS ACCOMPANIED BY SOME TOWERING CUMULUS CLOUDS. THE CIRRUS ALSO GIVES THE POSITION OF THE SUB TROPICAL JET STREAM. THE DENSE CIRRUS THAT HAD MASKED KAUAI COUNTY AT SUNSET HAVE THINNED DURING THE EVENING. THIS HAS GIVEN FORECASTERS TO VIEW THE LOW CLOUD SITUATION OF THE MAIN HAWAIIAN ISLANDS AND ITS SURROUNDINGS. SATELLITE IMAGERY SHOWS SCATTERED TO BROKEN COVERAGE OF SHOWER BEARING CLOUDS EMBEDDED IN THE TRADE WIND FLOW. THIS IS CONFIRMED BY WEATHER RADAR WHICH IS DETECTING SCATTERED SHOWERS OVER THE WINDWARD WATERS FROM OAHU TO THE BIG ISLAND AND THE WATERS OFF THE KAU COAST. A PLUME OF TWO OF SHOWERS ARE ALSO PRESENT ACROSS THE STATE/S LEEWARD WATERS...ORIGINATING FROM THE KONA COAST. THE KONA COAST AND ADJACENT WATERS HAVE TURNED MOSTLY CLOUDY LATELY WITH ISOLATED SHOWERS. SURFACE OBSERVATIONS AND SATELLITE IMAGERY...BOTH SUPPORT LOCALLY BROKEN LOW CLOUDS WITH A FEW SHOWERS OVER THE WINDWARD AND MOUNTAINS DISTRICTS OF MAUI AND THE BIG ISLAND...AND FAIR SKIES OVER THE LEEWARD COMMUNITIES OF THE SMALLER ISLANDS. THE LOW LEVEL WINDS AROUND THE STATE IS TRADES BLOWING AT 15 TO 20 MPH. IN THE TROPICS SOUTH OF THE HAWAIIAN ISLANDS...THERE HAS BEEN A SLIGHT UPTICK IN THUNDERSTORM ACTIVITY ALONG THE INTERTROPICAL CONVERGENCE IN PAST COUPLE OF HOURS. THE ACTIVITY IS MAINLY WITHIN 100 MILES EITHER SIDE OF A LINE FROM 11N146W TO 10N166W. ISOLATED MODERATE THUNDERSTORMS ARE OCCURRING BETWEEN 10N AND 06N FROM 170W TO THE DATELINE. $$ LAU +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
