A weakening cold front or shear line will sink southeastward
through the Big Island on Sunday with scattered showers and breezy
north winds (about 20-25 kts with higher gusts) in its wake. Winds
will slowly subside and veer back to east-northeasterly then
easterly next week as heights build over the area. A typical trade
pattern is expected for much of next week with generally light
windward/mauka showers. By next Friday, the ensembles show
troughing developing to the northwest of the area and either
passing by to the north (per most of the ECMWF and Canadian
ensembles) or settling near 160W (per most of the GEFS). With some
ensemble overlap near Hawai'i, prefer something along the lines of
a weaker version of the 00Z GFS which would be wetter than the 00Z
ECMWF.
