A WEST TO EAST FLOWING JET STREAM FLOWING ALONG 30N IN THE WESTERN NORTH PACIFIC ABRUPTLY TURNS NORTHWARD NEAR 170W AS IT SLAMS INTO A STRONG UPPER LEVEL RIDGE CENTERED ALONG 150W. HOWEVER...A SMALL AMOUNT OF THE ENERGY FROM THE JET STREAM IS UNDERCUTTING THE UPPER RIDGE...SPILLING OVER THE MAIN HAWAIIAN ISLANDS...AND DROPPING INTO A CUTOFF UPPER LEVEL LOW CENTERED ABOUT 375 MILES NORTHEAST OF THE BIG ISLAND NEAR 23N150W. THE UPPER LEVEL LOW IS DRIFTING TO THE EAST AND IS SUPPORTING A LOW LEVEL TROUGH ALONG 29N152W...24N151W...AND 18N151W THAT IS DRIFTING TO THE WEST. TO THE EAST OF THE TROUGH...A 400 MILE WIDE AREA OF BROKEN TO OVERCAST LAYERED CLOUDS IS CENTERED ALONG 26N149W... 20N146W...AND 14N146W...WITH ISOLATED...EMBEDDED THUNDERSTORMS RISING TO 43 KFT. TO THE WEST OF THE MAIN HAWAIIAN ISLANDS...A FRONT IS MOVING ALONG THE EASTERN END OF THE ZONAL JET STREAM. THE FRONT IS MARKED BY A 225 MILE WIDE BAND OF BROKEN LAYERED CLOUDS WITH EMBEDDED THUNDERSTORMS RISING TO 44 KFT ALONG 30N167W TO 26N171W. THE FRONT NARROWS AND CONTINUES TO THE WEST TO 23N180 AS A 100 MILE WIDE BAND OF BROKEN LOW CLOUDS. THE FRONT IS TRAVELLING TO THE EAST NEAR 25 MPH. PREFRONTAL THUNDERSTORM COVERAGE HAS DIMINISHED THIS AFTERNOON BUT PERSISTS BETWEEN THE FRONT AND 163W NORTH OF 24N...ABOUT 300 MILES NORTHWEST OF KAUAI. THE SYSTEMS TO THE WEST AND EAST OF THE MAIN HAWAIIAN ISLANDS ARE HOLDING SURFACE HIGH PRESSURE FAR NORTH NORTHEAST OF THE AREA... RESULTING IN A WEAK TRADE WIND FLOW. FEW TO SCATTERED LOW CLOUDS NEAR KAUAI ARE TRAVELING FROM THE EAST AROUND 10 MPH...BACKING OUT OF THE NORTHEAST ACROSS THE REST OF THE STATE. UNDER THE WEAK FLOW...AFTERNOON SEA BREEZES HAVE PRODUCED BROKEN TO LOCALLY OVERCAST LOW CLOUDS OVER LEEWARD TERRAIN ON ALL ISLANDS. CLOUD COVER ACROSS WINDWARD TERRAIN IS SLIGHTLY LESS EXTENSIVE...THOUGH BROKEN LOW CLOUDS ARE FOUND ACROSS MOST AREAS. MIDDAY... SATELLITE DERIVED...PRECIPITABLE WATER ESTIMATES OVER AND JUST UPSTREAM OF THE ISLANDS ARE RUNNING BETWEEN 1 TO 1.1 INCHES...SLIGHTLY BELOW NOVEMBER NORMS. $$ DWROE +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
