A weakness aloft, just west of the state, will retrograde westward
over the next couple of days to gradually allow upper ridging to
return. An associated deep plume of moisture over the islands,
believed to be the tropical remnants of Greg, will slide south and
west and depart the islands by Monday. This may result in
increasing widespread showers and locally heavier rain over the
weekend. Next week then, a drier and more typical forecast is
expected, as upper ridging builds and easterly trades resume. An
upper trough over the pacific will attempt to build south toward
Hawaii along with a surface cold front but neither will reach the
state. Overall the global models show good agreement with minimal
spread over the next week.
