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 154W. 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 DROPPING INTO A WEAK UPPER LEVEL TROUGH JUST EAST OF THE STATE. THIS UPPER TROUGH RUNS ALONG 30N142W TO A WEAKENING UPPER LEVEL LOW CENTERED NEAR 23N144W TO 16N153W. THE UPPER LOW IS FILLING AS IT MOVES TO THE EAST NORTHEAST AT 15 MPH. A THINNING MASS OF BROKEN LAYERED CLOUDS ALONG THE EASTERN FLANK OF THE UPPER LOW IS FOUND FROM 26N TO 20N EAST OF 144W. A WEAK SURFACE TROUGH THAT ORIGINATED FROM THIS AREA IS DRIFTING WESTWARD ALONG 23N153W TO 19N152W...ABOUT 175 MILES EAST OF THE BIG ISLAND. THE UPPER LEVEL TROUGH TO THE WEST IS SUPPORTING A FRONT 425 MILES NORTHWEST OF KAUAI. THE FRONT IS MARKED BY A 250 MILE-WIDE BAND OF BROKEN LOW CLOUDS ALONG 30N162W...27N166W...AND 25N171W...NARROWING TO 100 MILES WIDE TO 24N180. TO THE EAST OF 166W...ISOLATED THUNDERSTORMS RISE TO 47000 FT ALONG THE LEADING EDGE OF THE FRONT...WHICH IS MOVING TO THE EAST AROUND 18 MPH. THE WESTERN END OF THE FRONT IS NEARLY STATIONARY. 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 NORTHEAST AT LESS THAN 10 MPH...LIGHT ENOUGH TO ALLOW SEA BREEZES TO TAKE OVER ON LAND. AS A RESULT...BROKEN TO OVERCAST LOW CLOUDS HAVE DEVELOPED ALONG ALL SLOPES BELOW 10000 FT THIS AFTERNOON. $$ DWROE +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
