Wet pattern will continue for a couple more days as the weakness
aloft slowly moves southwestward away from the region. By late
Saturday and Sunday, drier air should work into the region and
surface high pressure will drift westward along 34N, promoting a
more typical trade pattern. For next week, the ensembles show a
building upper high to the NW of the area near 30N/170E that is
forecast to slide westward through Thursday which may allow
another weak upper trough to move toward or over Hawai'i. In
addition, the remnants of what is currently Tropical Storm Orlene
may approach the islands by next Thursday. The recent 00Z/06Z GFS
were on the more aggressive side of the multi-center ensemble
envelope as far as increasing moisture over the eastern islands
next Thursday. Please consult the latest information from the
National Hurricane Center on Orlene.
