Hawaii Extended Forecast Discussion
NWS Weather Prediction Center College Park MD
821 AM EDT Wed May 24 2017

Valid 00Z Thu May 25 2017 - 00Z Thu Jun 01 2017

Dissipating boundary just to the north of Kauai will wash out as a
strong high pressure (1041mb) slides northeastward and weakens.
Moisture axis with the front will slowly sink a bit farther south
and linger for a few days before PW values decrease. Showers will
be more widespread over Kauai and maybe Oahu into Thursday.
Heights will lower later this week into the weekend as a trough
swings by to the northeast of the region, but the area will stay
on the relative drier side of the upper flow, with mainly
scattered windward showers. Next week, ensembles agree on rising
heights to the NW and SE of the 50th state that eventually
converge over Hawai'i during the middle of the week, promoting a
rather quiet and drier pattern with slowly increasing trades.
