HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
239 AM EST FRI MAR 03 2023
VALID 00Z SAT MAR 04 2023 - 00Z SAT MAR 11 2023
ANOTHER DAY OF WET TRADE WIND WEATHER IS LIKELY FRIDAY, AS A
PACIFIC HIGH TO THE NORTH CREATES A PRESSURE GRADIENT FOR EASTERLY
WINDS WITH SUFFICIENT MOISTURE IN PLACE. A WEAK UPPER LOW ATOP THE
STATE CONTINUES TO PROVIDE INSTABILITY FOR POTENTIALLY EVEN SOME
THUNDERSTORMS, AND AMPLE SHOWERS THAT COULD BE LOCALLY HEAVY. BUT
LATE FRIDAY AND OVER THE WEEKEND, LOW PRESSURE IS FORECAST TO PUSH
EASTWARD ACROSS THE PACIFIC AND DISPLACE THE SURFACE HIGH. THIS
WILL QUICKLY WEAKEN THE WINDS OVER HAWAII FOR A SEA/LAND BREEZE
PATTERN WITH FEWER SHOWERS OVERALL. NEXT WEEK, TROUGHING ALOFT
ACROSS THE PACIFIC AS WELL WILL HELP PUSH COLD FRONTS ACROSS
HAWAII, SERVING TO FOCUS MOISTURE ALONG AND AHEAD OF THE FRONTS
FOR SHOWERS AND POSSIBLE STORMS. MULTIPLE FRONTS AND THUS MULTIPLE
ROUNDS OF RAIN ARE POSSIBLE ACROSS ALL ISLANDS, BEFORE A DRYING
TREND BEHIND THE FRONTS BY AROUND THURSDAY-FRIDAY OF NEXT WEEK.
