THE JET STREAM IS FLOWING OUT OF THE WESTERN PACIFIC INTO AN UPPER TROUGH ALONG 30N...ABRUPTLY BOTTOMING OUT AND TURNING NORTH NEAR 160W AS IT SLAMS INTO AN UPPER LEVEL RIDGE CENTERED ALONG 155W. THE JET ROUNDS THE TOP OF THE UPPER RIDGE IN ALASKA THEN DIVES INTO A BROAD AND DEEP UPPER TROUGH CENTERED OVER THE EASTERN PACIFIC AND WESTERN U.S. A SMALL PORTION OF THE JET STREAM ENERGY FROM THE EAST PAC UPPER TROUGH IS CARVING OUT A WEAK UPPER LEVEL TROUGH JUST EAST OF THE STATE. THIS UPPER TROUGH RUNS ALONG 30N144W TO A WEAKENING UPPER LEVEL LOW CENTERED NEAR 23N145W TO 17N156W. THE UPPER LOW IS FILLING AS IT MOVES TO THE EAST AT 15 MPH. BROKEN LAYERED CLOUDS ARE FOUND ALONG THE EASTERN FLANK OF THE UPPER LOW FROM 26N TO 20N EAST OF 146W. ISOLATED THUNDERSTORMS WITH TOPS TO 36 KFT ARE FLARING TO THE SOUTHWEST OF THE UPPER LOW AS FAR AWAY AS 21N150W. A WEAK SURFACE TROUGH IS DRIFTING WESTWARD FROM THIS AREA ALONG 22N152W TO 20N152W...ABOUT 200 MILES NORTHEAST OF THE BIG ISLAND. THE UPPER LEVEL TROUGH TO THE WEST IS SUPPORTING A FRONT 500 MILES NORTHWEST OF KAUAI. THE FRONT IS MARKED BY A 200 MILE-WIDE BAND OF BROKEN LOW CLOUDS ALONG 30N164W AND 26N171W. ISOLATED THUNDERSTORMS RISE TO 47 KFT ALONG THE LEADING EDGE OF THE FRONT. TO THE WEST OF THE FRONT...HIGH CLOUDS ARE STREAMING OVER MIDWAY ATOLL FROM A SYSTEM FARTHER WEST. THE FRONT NORTHWEST OF KAUAI AND THE SURFACE TROUGH NORTHEAST OF THE BIG ISLAND HAVE WEAKENED THE PRESSURE GRADIENT OVER THE STATE... LEADING TO A WEAK TRADE WIND FLOW NEAR THE ISLANDS. FEW TO SCATTERED LOW CLOUDS NORTH OF THE ISLANDS ARE TRAVELLING FROM THE EAST NEAR 10 MPH...LIGHT ENOUGH TO ALLOW LAND BREEZES TO PERSIST THIS MORNING. AS A RESULT...SKIES OVER THE ISLANDS ARE MOSTLY CLEAR...WITH THE EXCEPTION OF FEW LOW CLOUDS OVER WINDWARD KAUAI AND OAHU. $$ DWROE +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
