LAYERED CLOUDS WITH EMBEDDED TOWERING CUMULUS /TCU/ AND CUMULONIMBUS /CB/ CLOUDS COVER THE SOUTHEASTERN FLANK OF THE LOW TO AROUND 700 MILES AWAY FROM THE CENTER. LIGHTNING DETECTION INSTRUMENTS HAVE PICKED UP POSITIVE STRIKES WITH THE EMBEDDED STORM CELLS AND TOPS EXTEND TO 45 KFT IN HEIGHT. ANOTHER UPPER LOW IN THE NORTH CENTRAL PACIFIC IS CENTERED AT 37N174W AND IS NEARLY STACKED ON TOPS OF IT/S SURFACE REFLECTION AS THE LOW LEVEL CLOUD CIRCULATION CAN BE OBSERVED ON INFRARED SATELLITE. THE ASSOCIATED WEAKENING COLD FRONT IS OBSERVED FROM 35N165W TO 25N172W CONSISTING OF A 225 MILE WIDE BAND OF LAYERED AND CIRRUS CLOUDS. CLOUDS FROM THE FRONT DO EXTEND FURTHER SOUTH THAN 25N BUT ARE BEING PUSHED BACK WEST BY A SURFACE RIDGE. THE RIDGE EXTENDS FROM A HIGH CENTERED AT 33N147W AND RUNS ALONG A LINE TO 29N162W TO 24N174W ACCORDING TO SATELLITE SCATTEROMETER DATA. CIRRUS CLOUDS ARE ALSO PASSING ON THE NORTH SIDE AN UPPER RIDGE WITH AN AXIS FROM 20N173W TO 11N173W. THE MENTIONED SURFACE HIGH AND RIDGE ARE PRODUCING THE FRESH TO STRONG TRADE WINDS OVER THE MAIN HAWAIIAN ISLANDS THIS EVENING. WINDWARD COASTAL WATERS ARE DOMINATED WITH SCATTERED OPEN-CELLED CUMULUS CLOUDS AND ISOLATED SHOWERS. LOW CLOUDS UPSTREAM OF THE ISLANDS ARE MOVING FROM THE EAST AROUND 25 MPH. THESE CLOUDS ARE PUSHING ONTO WINDWARD AND MOUNTAIN PORTIONS OF THE ISLANDS...THROUGH CLOUD COVER IS NOT AS EXTENSIVE AS IT HAS BEEN OVER THE LAST 24 HOURS AND SOUNDING MOISTURE VALUES HAVE SHOWED A CONTINUED DRYING TREND SINCE THEN. LEEWARD SIDES OF THE ISLANDS ARE MOSTLY CLEAR WITH THE EXCEPTION OF THE KONA COAST ON THE BIG ISLAND WHERE BROKEN AFTERNOON SEABREEZE CLOUDS STILL REMAIN. LEEWARD WATERS ARE ALSO MOSTLY CLEAR THIS EVENING WITH THE EXCEPTION OF SOME PLUME CLOUDS WEST OF THE BIG ISLAND...LANAI AND MOLOKAI. ISOLATED THUNDERSTORMS ARE PRESENT FAR SOUTH OF THE STATE IN THE ITCZ...MOSTLY BETWEEN LATITUDES 06N AND 09N. SOME OF THE STORM CELLS EAST OF 151W ARE BEING ENHANCED BY THE UPPER LEVEL DYNAMICS OF THE MENTIONED UPPER LOW AT 21N147W AND BRINGING THUNDERSTORMS NORTH TO AROUND 12N. $$ FOSTER +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
