The episode as NWS HFO wrote it up.
A front moving through the islands triggered heavy showers and high winds, especially over the summits of Mauna Kea and Mauna Loa on the Big Island of Hawaii. The costs of any damages were not available. And there was one report of a woman being injured by a falling tree on Kauai on the 30th.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Honolulu, HI wrote its last area forecast discussion before the first event at Dec 26, 4:00 AM HST, 5 hours 30 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HONOLULU HI 400 AM HST FRI DEC 26 2014 .SYNOPSIS... LIGHT NORTHERLY WINDS AND COOL TEMPERATURES WILL PREVAIL THROUGH THE WEEKEND. CLOUDS AND LIGHT SHOWERS WILL LINGER MAINLY OVER NORTH THROUGH WEST SLOPES. MORE TYPICAL TRADE-WIND CONDITIONS WILL RETURN GRADUALLY BY SUNDAY NIGHT AND MONDAY. A WEAK FRONT WILL MOVE SOUTHEAST ACROSS THE STATE FROM MONDAY NIGHT OR TUESDAY INTO WEDNESDAY. && .DISCUSSION... SURFACE OBSERVATIONS AROUND THE MAIN HAWAIIAN ISLANDS REPORTED GENERALLY LIGHT WESTERLY TO NORTHWESTERLY WINDS. THE SUPPORTING TROUGH ALOFT NOW DIRECTED MOST OF ITS ENERGY TO THE NORTHEAST... AWAY FROM THE STATE. CLOUD COVER CONSISTED MOSTLY OF COLD-AIR CUMULI BREAKING IN WAVES OVER THE ISLANDS FROM THE NORTHWEST. OVERALL... THESE STABLE CLOUDS IN THE COOL POST-FRONTAL AIR MASS PRODUCED LITTLE RAIN. HOWEVER...BANDING IN THE CLOUD FIELD PRODUCED RAIN FROM OAHU TO MAUI EARLIER IN THE NIGHT...AND UPLIFT ALONG NORTH SLOPES OF THE SMALLER ISLANDS CONTINUED TO SQUEEZE OUT LIGHT RAIN. SATELLITE ESTIMATES OF PRECIPITABLE WATER DETECTED PLUMES OF ENHANCED MOISTURE SHEARING OFF FROM THE OCCLUSION TO THE NORTH OF THE STATE. GUIDANCE PREDICTED THESE PLUMES TO MOVE SOUTH OVER THE ISLANDS AT TIMES THROUGH THE WEEKEND...PROVIDING FUEL FOR PRECIPITATION IN THE OTHERWISE FAIRLY DRY AIR MASS. POPS AND RELATED FIELDS HAVE BEEN INCREASED...MAINLY FOR THIS MORNING...BUT ALSO THROUGH THE WEEKEND MORE GENERALLY. DESPITE THE HIGHER POPS...ACCUMULATION SHOULD REMAIN LOW HOWEVER. STRONG WINDS OVER HIGHER ELEVATIONS OF THE BIG ISLAND DROPPED OFF BRIEFLY AROUND MIDNIGHT...BUT RECENTLY HAVE RISEN SIGNIFICANTLY AGAIN...AND MAY NOT ABATE COMPLETELY UNTIL THE MID-LEVEL TROUGH MOVES AWAY MORE DEFINITIVELY ON SATURDAY. FOR NOW...A WIND ADVISORY IS IN EFFECT FOR THE SUMMITS ONCE MORE. GUIDANCE PREDICTED SURFACE RIDGING TO THE NORTH TO EXPAND EASTWARD SOMEWHAT MORE SLOWLY THAN USUALLY HAPPENS AFTER A FRONT HERE...SO THAT LOCAL WINDS WILL TURN NORTHERLY...AND THEN NORTHEASTERLY...ONLY GRADUALLY THROUGH THE WEEKEND. WIND DIRECTION MAY NOT RETURN TO CLIMATOLOGY MUCH BEFORE SUNDAY NIGHT OR MONDAY MORNING. NORTHERLY ADVECTION WILL KEEP TEMPERATURES ON THE LOW SIDE DURING THIS TIME. BY MONDAY NIGHT...ANOTHER FRONT WILL APPROACH FROM THE NORTHWEST. SOLUTIONS GENERALLY DEPICTED THIS FEATURE AS WEAKER...AND RECEIVING LESS SUPPORT FROM ALOFT...THAN THE LAST FRONT. STILL...CONSENSUS DID EXPECT THIS FEATURE TO HOLD TOGETHER LONG ENOUGH TO APPROACH THE BIG ISLAND BY WEDNESDAY NIGHT. RAINFALL AND WINDS ACCOMPANYING THIS FRONT LIKELY WILL BE QUITE MODEST. BY LATE NEXT WEEK...GUIDANCE HINTED THAT A MUCH STRONGER MID-LEVEL TROUGH WILL DIG SOUTH SHARPLY TOWARD THE ISLANDS...SUPPORTING THE APPROACH OF A MUCH MORE SUBSTANTIAL FRONT CARRYING LARGE AMOUNTS OF PRECIPITABLE WATER. IF CONSENSUS IS RIGHT...THEN NEXT FRIDAY INTO SATURDAY MAY BE RATHER WET. THE 06Z GFS RUN DEPICTED SUBSTANTIAL SHOWER DEVELOPMENT IN CONVERGENCE AHEAD OF THIS NEXT FRONT... POSSIBLY ALONG THE REMNANTS OF THE ONE FROM EARLIER IN THE WEEK. IF SO...THEN THE BIG ISLAND AND MAUI COUNTY MAY START TO RECEIVE SIGNIFICANT RAINFALL AS EARLY AS THURSDAY NIGHT. THE FORECAST HAS BEEN NUDGED IN THIS DIRECTION...BUT GENTLY...CONSIDERING SOLUTION UNCERTAINTY THAT FAR OUT. && .MARINE... SURF HEIGHTS ALONG NORTH-FACING SHORES ARE EXPECTED TO REMAIN BELOW ADVISORY LEVELS THROUGH THIS AFTERNOON. ANOTHER MODERATE NORTHWEST SWELL SHOULD ARRIVE TONIGHT...PEAK ON SATURDAY...AND THEN DIMINISH A LITTLE ON SUNDAY. A REINFORCING NORTHWEST SWELL WILL ARRIVE ON MONDAY. OVER THE COASTAL WATERS...WIND SPEEDS AND COMBINED SEAS ALSO ARE EXPECTED TO REMAIN BELOW THE THRESHOLD FOR A SMALL CRAFT ADVISORY THROUGH TODAY. THE PENDING MODERATE NORTHWEST SWELL MAY LIFT COMBINED SEAS TO NEAR THE ADVISORY LEVEL BRIEFLY OVER EXPOSED COASTAL WATERS. && .HFO WATCHES/WARNINGS/ADVISORIES... WIND ADVISORY UNTIL 6 PM HST THIS EVENING FOR BIG ISLAND SUMMITS. && RYSHKO
