Strong upper high to the WNW of the region (+2 sigma 500mb
heights) will weaken in place near 25N/Dateline through early next
week. Very deep troughing south of the Gulf of Alaska (-5 sigma
500mb heights) will drag the tail end of a cold front through
Hawai'i Monday into Tuesday but with limited enhanced
precipitation. Trades should increase near the frontal passage and
then decrease late next week as the ensembles as upper ridging and
a surface high builds into the area yet again. Another surge in
moisture may approach the northwestern islands next Thursday into
Friday as another low deepens well north of the region near 45N
and the tail end of its front sinks southward, fighting the
ridging overhead. The trend seems to be to hold the front farther
north.
