Guidance still reasonably agrees that moderate to locally breezy
mean trades will prevail this week as high pressure bridges to the
north of the state. Meanwhile, mean upper troughing over the state
should enhance instability and may prove slow to dislodge. This
pattern will favor showers over windward and mountain areas, but
with potential for some spillage into leeward areas. Blended
precipitation water satellite loops show deeper moisture up into
the state and flood advisories have already been issued for the
southern islands. There is also some threat for wintry weather in
this pattern over higher elevations of Mauna Loa and Mauna Kea
where there is a Winter Weather Advisory in effect. Trades may
weaken in a drier pattern by later weekend into early next week as
ample closed upper trough development over the mid-latitudes may
drive a trailing cold front to the northwest of the state.
Overall, predictability and continuity overall seem better than
average for this forecast period.
