Hawaii Extended Forecast Discussion
NWS Weather Prediction Center College Park MD
112 AM EST Sat Nov 7 2020

Valid 00Z Sun Nov 8 2020 - 00Z Sun Nov 15 2020

The weather pattern for this weekend will be featured with a large
upper ridge centered to the northeast of Hawaii, and an amplifying
trough to the west of the state that evolves into a closed low
near 175W, with the GEFS mean slightly stronger with it. 
Meanwhile, the upper ridge along with the surface high retrogrades
westward some by the middle to end of next week, with good overall
model agreement on this.

In terms of sensible weather, the building high north of the state
will tend to increase the Trades with windy conditions at times
for the beginning to middle of the week.  The upper low and
surface trough are expected to be far enough west to not cause a
heavy rainfall threat, with mainly terrain induced showers for
much of the forecast period.  There may more numerous showers by
next Friday as a weak upper low could approach the Big Island from
the east.
