NEAR THE ISLANDS...BROKEN LOW CLOUDS TRAVELLING FROM THE EAST AT 25 TO 30 MPH ARE PILED UP ALONG WINDWARD AND MAUKA PORTIONS OF THE STATE. THE TRADES ARE STRONG ENOUGH TO CARRY SCATTERED TO LOCALLY BROKEN LOW CLOUDS OVER LEEWARD PORTIONS OF THE SMALLER ISLANDS AS WELL. HIGH PRESSURE ALOFT CENTERED NORTH OF THE ISLANDS NEAR 30N152W IS PRODUCING STRONG SUBSIDENCE AND STABLE CONDITIONS OVER AND EAST OF THE STATE THAT IS CAPPING THE LOW CLOUDS AROUND 9 KFT. SATELLITE- DERIVED PRECIPITABLE WATER VALUES ARE HOVERING AROUND 1.25 TO 1.4 INCHES NEAR THE ISLANDS...DROPPING RAPIDLY TO THE EAST AND REACHING ABOUT 1 INCH NEAR 150W. THE STABLE CONDITIONS FROM THE HIGH PRESSURE ALOFT IS SPREADING IN FROM THE EAST OVER THE ISLANDS AS AN UPPER LOW 560 MILES WEST OF KAUAI NEAR 22N169W MOVES OFF TO THE NORTHWEST AROUND 12 MPH. THIS WEAK FEATURE IS MANAGING TO TRIGGER ISOLATED TOWERING CUMULUS CELLS...AND POSSIBLY A THUNDERSTORM...WITH TOPS TO 30 KFT DIRECTLY UNDER THE CENTER. TO THE SOUTH OF THE STATE...THUNDERSTORM ACTIVITY WITHIN THE ITCZ IS LESS THAN NORMAL...THOUGH A WEAK TROUGH ALONG THE NORTHERN FRINGE OF THE ITCZ IS LOCATED 525 MILES SOUTHEAST OF THE BIG ISLAND. THE TROUGH RUNS ALONG 15N148W TO 11N142W AND IS MOVING TO THE WEST AT 20 MPH. BROKEN CUMULUS CLOUDS ARE FOUND WITHIN 150 MILES OF THE TROUGH...WHILE A COLLAPSING THUNDERSTORM IS NOTED AT THE SOUTHERN END OF THE FEATURE. ELSEWHERE...A COLD FRONT MOVING TO THE SOUTHEAST AT 15 MPH IS NEAR THE NORTHWEST PORTION OF THE AREA AT 30N180 AND IS WEAKENING THE TRADE WIND FLOW NEAR MIDWAY ATOLL. $$ DWROE +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
