HAWAII EXTENDED FORECAST DISCUSSION  
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD  
303 AM EDT FRI APR 23 2021  
 
VALID 00Z SAT APR 24 2021 - 00Z SAT MAY 01 2021  
 
A WEAK UPPER LOW DRIFTING SOUTHWARD OVER THE ISLANDS THIS WEEKEND  
MAY BRING A BRIEF DISRUPTION TO TRADES AND POSSIBLY INCREASE  
WINDWARD SHOWERS FOR MAINLY THE BIG ISLAND. OTHERWISE, HIGH  
PRESSURE BUILDING NORTH OF HAWAII WILL MAINTAIN MODERATE TO BREEZY  
TRADE WINDS THROUGH MUCH OF THE NEXT WEEK ALONG WITH MOSTLY DRY  
WEATHER. THE GUIDANCE INDICATES A FRONT WILL SINK SOUTHEASTWARD  
FROM THE DATELINE AROUND MIDWEEK, BUT SHOULD STAY NORTH OF THE  
STATE OR MAYBE OVER THE FAR NORTHERN ISLANDS. IF THE FRONT REACHES  
HAWAII AT ALL, EXPECT SOME INCREASE IN SHOWERS ALONG AND AHEAD OF  
THE FRONT BY LATER NEXT WEEK.
