A mid-level high will continue to extend across the region between
upper high centers off California and near 35N/175E through the
weekend as a brief surge in moisture passes from east to west.
Early next week, current tropical storm Lane (10.4N/126.4W as of
09Z) is forecast to track WNW to near 15N/150W per the latest NHC
update with a trend westward just south of the Big Island next
Tue-Thu per the ensemble consensus and yesterday's NHC/WPC day 6-7
(Tue/Wed) coordination call. Ensembles also indicate the upper
high near the Dateline to move eastward to about 36N/160W by next
Thursday which should help keep the system to the south of the
area. Precipitation is highly uncertain next week as it depends on
how close the system approaches Hawai'i. As always, please consult
the latest forecast from the NHC and later the CPHC.
