Mid-level ridging that currently forms an umbrella over the region
is forecast to be replaced by troughing early next week.
Associated surface cold front should approach and perhaps dip
through the NW islands but mostly wash out as it sinks toward
21-22N lat by midweek. The ensembles diverge by this point with
many 00Z GEFS members -- which are a bit deeper/slower with the
upper trough -- lowering PW values near Lihue to near or under 1
inch while the ECMWF members -- a bit quicker/weaker with the
trough -- maintain values near 1.50 inches. 06Z GFS and 00Z ECMWF
may forge a reasonable solution. By the end of next week,
additional troughing should pass by to the north of the state,
though this time the ECMWF members lag behind the GEFS members.
