A BROAD UPPER LEVEL HIGH IS CENTERED NEAR 30N150W OF THE MAIN HAWAIIAN ISLANDS AND IS ALSO BUILDING EAST TO WEST OVER THE STATE TONIGHT. THIS IS RESULTING IN STRONG SUBSIDENCE AND STABLE CONDITIONS OVER AND EAST OF THE STATE THAT IS CAPPING THE LOW CLOUDS AROUND 8 KFT. AT THE SURFACE...A STRONG SURFACE HIGH CENTERED NEAR 40N135W HAS AN ASSOCIATED RIDGE EXTENDING TO 28N158W. FURTHER WEST IS A COLD FRONT WHICH IS TRACKING EASTWARD. THE SOUTHERN FRINGE OF AN ASSOCIATED OVERCAST CLOUD BAND GOES FROM 40N154W TO 30N174W TO 28N174E AND IS AROUND 200 MILES IN WIDTH. THE COMBINATION OF THE STRONG HIGH FAR TO THE NORTHEAST AND THE APPROACHING SYSTEM IS RESULTING IN MODERATE TO FRESH EAST-SOUTHEAST WINDS OVER THE MAIN HAWAIIAN ISLANDS TONIGHT. SOUNDINGS FROM HILO AND LIHUE FROM EARLIER TODAY ALONG WITH SATELLITE-DERIVED PRECIPITABLE WATER VALUES SHOW THESE NUMBERS AROUND 1.2 TO 1.3 INCHES...BUT RAPIDLY DROPPING RAPIDLY TO 1 INCH UPSTREAM TO TO THE EAST. FAR 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 APPROACHING SOUTHERN BIG ISLAND. THE TROUGH IS LOCATED ALONG 18N156W TO 11N141W AND IS TRAVELLING TO THE WEST NEAR 25 MPH. BROKEN CUMULUS CLOUDS ARE MOVING ONTO THE BIG ISLAND FROM THE EAST-SOUTHEAST AND RADAR IS PICKING UP SCATTERED SHOWERS OVER THE HILO DISTRICTS AND THE EASTERN COASTAL WATERS. MOST OF THE BIG ISLAND IS COVERED WITH THESE CLOUDS WITH THE EXCEPTION OF THE WATERS OVER THE KONA AND KOHALA COASTS AND ABOVE THE INVERSION LEVEL OF 8 KFT OVER THE INTERIOR. ACROSS THE STATE THIS EVENING...SCATTERED TO BROKEN CUMULUS AND STRATOCUMULUS CLOUDS ARE MOVING FROM THE EAST-SOUTHEAST AROUND 25 MPH. WHILE WINDS ARE PUSHING MUCH OF THESE CLOUDS OVER WINDWARD AND MAUKA AREAS TONIGHT...THE WINDS ARE STRONG ENOUGH TO CARRY SCATTERED TO LOCALLY BROKEN LOW CLOUDS ALONG WITH A FEW SHOWERS OVER LEEWARD PORTIONS OF THE SMALLER ISLANDS. RADAR IS PICKING UP WIDELY SCATTERED SHOWERS OVER MOST WINDWARD COASTS AND ADJACENT WATERS. $$ FOSTER +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
