HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
212 AM EST FRI DEC 13 2024
VALID 00Z SAT DEC 14 2024 - 00Z SAT DEC 21 2024
UPPER RIDGING OVER HAWAII SHOULD CONTINUE TO SUPPORT MODERATE TO
STRONG TRADE WINDS THROUGH AT LEAST THIS WEEKEND. TRADE WINDS
SHOULD TREND WEAKER AND SHIFT IN A MORE SOUTHERLY DIRECTION AS A
WEAK SHORTWAVE MOVES OVER JUST TO THE NORTH. THIS MAY BRING SOME
INCREASED MOISTURE AND SEA BREEZE INFLUENCED PRECIPITATION EARLY
TO MID NEXT WEEK. BY THURSDAY, THE GUIDANCE CONTINUES TO SHOW A
COLD FRONT AND ASSOCIATED MOISTURE BAND REACHING VERY CLOSE OR
INTO THE MAIN ISLANDS, WITH SOME INCREASE IN SHOWERS EXPECTED.
THERE IS SOME UNCERTAINTY STILL ON HOW FAR SOUTH THE COLD FRONT
MAY REACH BUT A GENERAL MODEL COMPROMISE SHOULD WORK WELL AT THIS
POINT GIVEN TYPICAL LOW PREDICTABILITY THIS FAR OUT IN TIME.
