A STRONG NORTHWESTERLY UPPER LEVEL JET IS MOVING INTO THE AREA ALONG THE SOUTHWESTERN FLANK OF THIS LOW. A WEAK NORTH TO SOUTH ORIENTED UPPER RIDGE AXIS IS LOCATED JUST EAST OF THE BIG ISLAND MOVING EAST AT 10 MPH. AN UPPER LOW CENTERED 1120 MILES NORTHEAST OF THE BIG ISLAND MOVING FURTHER TO THE NORTHEAST AT 10 TO 15 MPH. A 130 MILE WIDE BAND OF LAYERED CLOUDS IS CENTERED ALONG A LINE FROM 19N163W TO 31N157W. SCATTERED PRE-FRONTAL THUNDERSTORMS WITH TOWERING CUMULUS TOPS TO 37 KFT ARE EMBEDDED WITHIN THIS CLOUD BAND WHICH IS MOVING EAST AT 12 MPH. ANOTHER 80 MILE WIDE CLOUD BAND CONSISTING OF CUMULUS AND TOWERING CUMULUS IS POSITIONED ALONG A COLD FRONT FROM 30N160W TO 25N160W TO 22N164W WHICH IS ALSO TRAVELING EASTWARD AT THE SAME SPEED. ANOTHER FRONTAL CLOUD BAND CONSISTING ABOUT 200 MILES WIDE BAND OF CLOUDS STRETCHES FROM 37N174W TO 30N172W TO 22N174E.

THESE CLOUDS ARE MOVING ONTO OAHU AT THIS TIME. LOCAL RADAR IMAGERY REVEALS SCATTERED SHOWERS AND EMBEDDED ISOLATED THUNDERSTORMS COVERS KAUAI AND NIIHAU AND ARE CURRENTLY TRACKING EAST AT 10 TO 15 MPH TOWARDS OAHU. ELSEWHERE...SCATTERED LOW CLOUDS ARE FOUND OVER THE INTERIOR OF ALL OTHER MAIN HAWAIIAN ISLANDS...WITH CLOUD TOPS AROUND 9 TO 10 KFT IN HEIGHT. ITCZ CONVECTION IS SOMEWHAT LIMITED BETWEEN 06N AND 10N. ISOLATED THUNDERSTORMS PERSIST WEST OF 176W CROSSING THE DATELINE AND EAST OF 145W. A TROUGH WITH AN AXIS FROM 10N155W TO 17N142W AND IS PRODUCING A 100 MILE WIDE LINE OF SCATTERED THUNDERSTORMS. $$ FOSTER +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
