The next low pressure system crosses north of Hawaii Thursday
night around 30 degrees north, with the trailing cold front
crossing the state late Friday.  The ECENS and GEFS means have
come into good agreement on the track and intensity of the low. 
With enhanced southwesterly low level ahead of the front, periods
of heavy rainfall are likely for the southern facing terrain, and
this will include areas that don't often get significant rainfall
from the normal trade wind pattern.  It's possible that some
locations could get 2-4 inches of rain through Friday evening, and
this may lead to some flooding.

With the surface low and front lifting out of the region Saturday,
a quieter pattern returns for the weekend.  The subtropical high
slowly builds back in to the northwest of the state through early
next week, and the trade wind flow will veer from southwesterly to
northwesterly through Sunday, and then more northeasterly by early
next week.  Precipitation will return to the normal trade wind
induced showers.
