Forecasters' discussion

From the National Weather Service office in HFO, issued 3 hrs ago

Synopsis

High pressure far north of the Hawaiian islands will begin to weaken, allowing winds to decrease to moderate levels for the remainder of the week. Passing showers will be carried in on the trade wind flow over the next several days, with an increase in shower activity this weekend.

Short Term Update

The satellite imagery this evening continues to show unsettled cloud bands riding into each island on the trade winds. A band of cirrus clouds blanketing Maui and the Big Island are courtesy of a subtropical jet stream aloft.

The afternoon forecast grids look good. No evening updates.

Prev Discussion

Issued at 332 PM HST Tue Oct 20 2026 No significant changes to the forecast with the afternoon package. Main changes were to align the later parts of the forecast with the latest National Blend of Models (NBM). There remains uncertainty with the differences in the global models, so aligning with the NBM seems the prudent choice at this time.

A high pressure ridge remains to the north of the islands, maintaining a moderate to locally windy trade wind pattern over the region. As the associated high weakens, we expect the pressure gradient over the islands to relax, allowing trades to return to moderate levels across the islands.

Passing showers will continued to be carried in on the trade wind flow this evening, but with satellite derived precipitable water (PW) showing a drier than normal airmass upstream of the islands, we expect shower activity to taper off overnight, with isolated shower activity expected then through Friday.

Good model agreement continues between the ECMWF and GFS models that the high mentioned above will weaken Wednesday as a strong low, currently more than 2000 miles to the northwest, moves to the east and sets up far north of the islands Thursday. The low is forecasted to strengthen and sink southward into the weekend, with an associated front then moving towards the islands over the weekend. Currently both global models are in good agreement with showers increasing during the weekend and into next week.

There are indicators in the global models that winds atop the Big Island summits could reach warning levels during the first to middle part of the next week. The GFS is currently more aggressive that the ECMWF. The forecast for Monday through Wednesday has been nudged to the GFS solution, but tapered back a bit to account for the conservative nature of the ECMWF at this time.

An increase in dewpoints is expected during the second half of the weekend and into the early part of the new week, which will bring warm and humid conditions back to the islands.

Aviation

VFR. Moderate trades will hang in through Wednesday morning and then gradually weaken through the day. Widely scattered showers with only brief MVFR conditions possible within more organized showers.

AIRMET Tango is in effect for tempo moderate turbulence downwind of terrain below flight level 090.
