Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 200 AM EST Fri Dec 06 2019 Valid 00Z Sat Dec 07 2019 - 00Z Sat Dec 14 2019 Guidance shows that southeastward digging of mid-upper level shortwave over the state today will combine with pooled moisture with a decaying front to support a period of enhanced rainfall (snow at highest Big Island elevations). Guidance remains reasonable and consistent in tracking the heaviest activity just to the south of the main islands in a region coincident with deepest moisture as per latest blended precipitable water loops. Weakening high pressure will support enough trade flow to focus highest inland rainfalls over windward locations. The weekend will bring a drier trend with more land/sea breezes as high pressure reaches the eastern Pacific and another front approaches the northwestern islands. Guidance maintains modest differences for exact frontal position, but as a whole remains agreeable and run to run consistent. A favored consensus shows this front reaching very close to the northwestern islands before weakening. This concensus would also suggest that weak post-frontal high pressure will revive trades Monday-Tuesday as moderate moisture and ridging overhead should lead to mostly light shower activity. Yet another front will likely approach the area by next Thursday as an upper trough amplifies and passes to the north. This front, which still shows better than average agreement and continuity among the models/means given the distant time frame, would again disrupt trades and offer potential for increased rainfall into next Friday.
