Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 810 AM EDT Sat Sep 24 2016 Valid 00Z Sun Sep 25 2016 - 00Z Sun Oct 02 2016 Latest guidance shows no significant differences with large scale pattern. By Monday-Tuesday expect trades to strengthen to moderate/brisk levels as a front stalling well north of the state dissipates and trailing high pressure builds across the central/eastern Pacific. Showers will tend to favor windward locales but moisture may occasionally reach other locations as well. Precipitable water values should decrease somewhat after today with some day to day fluctuations thereafter. Latest GFS/ECMWF runs differ on exactly when and where PWATs may be relatively higher or lower. Scale is sufficiently small that predictability is quite low for that aspect of the forecast but at the moment these differences in PWATs appear to have fairly modest impact on expected rainfall.
