NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
309 AM EDT FRI MAR 15 2024
VALID 00Z SAT MAR 16 2024 - 00Z SAT MAR 23 2024
WEAK HIGH PRESSURE AT THE SURFACE IS EXPECTED TO BE IN PLACE JUST
NORTH OF HAWAII THROUGH FRIDAY AND INTO THE UPCOMING WEEKEND.
MEANWHILE, THE COLD FRONT WILL BE LINGERING NEAR AND JUST
SOUTHEAST OF THE BIG ISLAND THROUGH FRIDAY BEFORE GRADUALLY
DISSIPATING. A COL DEVELOPS IN THE SURFACE HIGH BY EARLY NEXT
WEEK WITH A FRONTAL BOUNDARY PASSING WELL NORTH OF THE ISLANDS
ACCORDING TO THE LATEST ENSEMBLE MEANS. THE SURFACE HIGH WILL
LIKELY BUILD BACK IN NORTH OF THE STATE GOING INTO THE MIDDLE TO
END OF NEXT WEEK.
THERE WILL LIKELY BE ENHANCED SHOWERS FOR THE BIG ISLAND THROUGH
LATE SATURDAY OWING TO THE VICINITY OF THE FRONTAL BOUNDARY, AND
LESS COVERAGE OF SHOWERS FARTHER NORTHWEST. THE ECMWF IS
GENERALLY HIGHER WITH QPF COMPARED TO THE GFS. SCATTERED SHOWERS
ARE LIKELY TO PERSIST BEYOND THIS TIME, BUT ABATING IN INTENSITY
AS A DRIER OVERALL ENVIRONMENT ADVECTS INTO THE REGION. LIGHT TO
MODERATE TRADE WIND FLOW FROM THE NORTHEAST IS EXPECTED THROUGH
EARLY NEXT WEEK, WITH SOME VEERING TO THE EAST BY THE MIDDLE OF
THE WEEK.
