Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 811 AM EDT Fri Aug 11 2017 Valid 00Z Sat Aug 12 2017 - 00Z Sat Aug 19 2017 Quiet pattern for Hawai'i over the next several days per the ensembles. A strong upper high (+2.5 sigma 500mb heights) to the north of the area will slowly drift northeastward, flatten, and reorient itself near 37N/136W by next Friday as it again strengthens. Breezy trades will continue into early next week as the sfc high reaches about 1031mb. Limited moisture (precipitable water values about 1-2 sigma below average) suggests generally light/scattered windward and mauka showers, some of which may spill over to leeward areas over the next several days. A weakness aloft will push through Hawai'i around next Wednesday/Thursday as trades weaken a bit but the ensembles do no show much of a rise in PW values through Friday. Fracasso
