HONOLULU (KHON2) – The ridge aloft is maintaining very stable conditions with sparse available moisture as evidenced by the statewide empty rain gauges.

The only caveat were the few windward and mauka Kauai rainfall gauges that picked up less than a tenth of 24 hour rainfall.

Generally, southerly winds have kept island-wide dew points elevated (average coastal upper 60s) thus making it feel more humid by winter standards.

The greatest concentrations of volcanic haze (vog) remain confined to Maui County and leeward Big Island but recent GOES GeoColor daytime imagery did depict haze creeping into eastern Oahu late this afternoon.

As the surface ridge axis travels north tonight, east winds filling in underneath it will aid in lowering dew points to more seasonable lower to middle 60s while transporting vog further west over Oahu into Monday.

Thus, Sunday’s conditions will be less sticky but more hazy over Oahu and Kauai.

The surface ridge will move north through early next week as a stronger area of high pressure develops far to the northwest.

This will allow gentle to locally breezy trades to develop across the entire island chain Sunday.

Persistent upper ridging aloft will maintain stable and rather dry conditions the next couple of days.

The highest chance of any rain will be across windward-facing coastal and mauka area and at higher elevation.

As trades fill in from the east tomorrow, Kauai’s leeward areas may experience thicker afternoon clouds and occasional light showers.

Vog concentrations will likely thin out as strengthening trades better mix out haze through a deeper boundary layer.

Trade winds will strengthen from Monday into Tuesday.
