Area forecast discussion, Feb 3, 4:00 PM HST, 52 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HONOLULU HI 400 PM HST TUE FEB 3 2009 .SYNOPSIS... SKIES WILL BE MOSTLY CLOUDY FOR THE NEXT COUPLE OF DAYS AS HIGH CLOUDS MOVE UP OVER THE STATE FROM THE SOUTH. WINDWARD AND MAUKA AREAS WILL EXPERIENCE SCATTERED SHOWERS AS MOISTURE RIDES IN WITH THE GUSTY TRADES. WINDS ARE EXPECTED TO DIMINISH LATER THIS WEEK AND INTO THE WEEKEND. && .DISCUSSION... IT LOOKS LIKE IT GOING TO BE RATHER CLOUDY OVER THE ALOHA STATE FOR THE NEXT COUPLE OF DAYS. AN UPPER TROUGH IS PRESENTLY LOCATED JUST TO THE SOUTHWEST OF THE STATE. THIS IS DRAWING UP A VAST SWATH OF HIGH CIRRUS CLOUDS ON ITS EASTERN PERIPHERY. THESE CIRRUS CLOUDS ARE RATHER THICK AND WILL LIKELY OBSCURE MUCH OF THE SUN AND BLUE SKIES ABOVE. MODELS GRADUALLY DRIFT THIS UPPER TROUGH EASTWARD SO THE CIRRUS SWATH SHOULD GRADUALLY SHIFT EASTWARD AS WELL WITH TIME. THE BIG ISLAND AND POSSIBLY MAUI WILL STILL EXPERIENCE THESE HIGH CLOUDS FOR A DAY OR TWO LONGER. IN THE LOWER LEVELS OF THE ATMOSPHERE REMNANT MOISTURE FROM AN OLD SHEARLINE IS PROVIDING LOW CLOUDS AND SHOWERS FOR MOST WINDWARD AND MAUKA AREAS. THE TRADE WINDS ARE SUFFICIENTLY STRONG ENOUGH TO BLOW A FEW OF THESE SHOWERS OVER LEEWARD AREAS OF THE SMALLER ISLANDS AT TIMES. THIS MOISTURE IS EXPECTED TO GRADUALLY SHIFT SOUTH AND WEST. THERE IS STILL ABUNDANT MOISTURE UPSTREAM OF THE ISLANDS SO THERE WILL STILL BE SCATTERED SHOWERS OVER WINDWARD AND MAUKA SECTIONS AS WE HEAD INTO THE WEEKEND. IT WILL BE RATHER BREEZY TONIGHT AS STRONG HIGH PRESSURE SLOWLY MOVES EASTWARD FAR NORTH OF THE STATE. WINDS SHOULD GRADUALLY DROP OFF LATE TOMORROW THROUGH THE REST OF THE WEEK AS THE HIGH TAKES UP A POSITION FAR NORTHEAST OF THE ISLANDS. TRADE WINDS WILL BE LIGHTER OVER THE WEEKEND. MOISTURE RIDING IN ON THE TRADES WILL CONTINUE TO BRING SCATTERED SHOWERS FOR WINDWARD AND MAUKA AREAS. ALSO THE ABOVE MENTIONED UPPER TROUGH MAY PLAY A FACTOR AS MODELS HAVE IS STALLING BUT WEAKENING OVER THE CENTRAL AND EASTERN HALF OF THE STATE. THE UPPER LOW MAY CAUSE SOME CONVECTIVE SHOWERS TO FORM WITH THE MOST LIKELY PLACE FOR THEM OCCURRING BEING OVER THE BIG ISLAND SLOPES MAINLY DURING THE AFTERNOON AND EVENING HOURS. && .MARINE... A SMALL CRAFT ADVISORY REMAINS UP THROUGH WEDNESDAY FOR ALL HAWAIIAN WATERS DUE TO STRONG WINDS AND ROUGH SEAS. MARGINAL HIGH SURF IS EXPECTED FOR NORTH FACING SHORES FROM NIIHAU TO MAUI THROUGH TONIGHT. THE COMBINATION OF A NORTH SWELL AND WIND WAVES PRODUCED BY THE TRADES WILL PRODUCE ADVISORY LEVEL SURF FOR EAST FACING SHORES THROUGH WEDNESDAY. && .HFO WATCHES/WARNINGS/ADVISORIES... HIGH SURF ADVISORY UNTIL 6 AM HST WEDNESDAY FOR NIIHAU-KAUAI LEEWARD-OAHU NORTH SHORE-MOLOKAI LEEWARD. HIGH SURF ADVISORY UNTIL 6 PM HST WEDNESDAY FOR KAUAI WINDWARD- OAHU KOOLAU-OLOMANA-MOLOKAI WINDWARD-MAUI WINDWARD WEST-MAUI CENTRAL VALLEY-WINDWARD HALEAKALA. HIGH SURF ADVISORY UNTIL 6 PM HST WEDNESDAY FOR SOUTH BIG ISLAND- BIG ISLAND NORTH AND EAST. SMALL CRAFT ADVISORY UNTIL 6 PM HST WEDNESDAY FOR ALL HAWAIIAN WATERS. && BURKE
