From the National Weather Service office in HFO, issued 4 hrs ago
Synopsis
High pressure far north of the Hawaiian islands will maintain a moderate to locally windy trade wind pattern over the region into the middle of the week. An area of showers moving in on the trades tonight will maintain passing showers over the windward and mountains into Tuesday. Moderate trades and fewer showers are expected during the second half of the week, with an increase in shower trends this weekend.
Short Term Update
Cloud bands riding into the islands on the brisk trade winds will continue to produce periods of showers favoring the windward mountain areas of all islands through early Tuesday morning.
The afternoon forecast grids look good, no evening updates.
Previous Discussion
Issued at 319 PM HST Mon Oct 19 2026 The forecast for tonight has been updated to increase PoPs and associated fields for the windward sides of the islands, particularly over Maui County and the Big Island with an area of showery low clouds riding in on the trade wind flow. Satellite derived precipitable water (PW) shows values 1.3 inches upstream of the islands. The afternoon soundings at Lihue and Hilo had 1.19 and 1.06 inches of PW respectively. The 1.3 is near normal for this time of year, so just expecting a few more showers than we have been seeing in the last couple of days.
High pressure far to the north will linger into Wednesday, with a tight pressure gradient over the islands maintaining the moderate to locally breezy trades. A few sites in the windiest locations (along ridges) have seen winds briefly reach advisory levels, but not expecting any widespread or persistent advisory conditions so have held off on any headlines. There is good model agreement with the ECMWF and GFS models that the high will weaken Wednesday as a strong low, currently far to the northwest in the Western Pacific, moves to the east and sets up far north-northwest of the islands. The high will weaken and move to the east, as the low deepens, and an associated front moves closer to the islands over the weekend.
With the high weakening, the pressure gradient over the islands will weaken, and winds are expected to return to moderate levels. A drier airmass moving over the islands will result in fewer showers during the Wednesday through Friday time period.
As the above mentioned front moves closer to the islands this weekend, moisture will be drawn northward over the islands, increasing shower activity. And then the second half of the weekend and into next week, the tail end of a front may impact the northern islands by increasing shower activity.
Aviation
Issued at 319 PM HST Mon Oct 19 2026 Breezy trades will persist through tomorrow. Passing showers will mainly be concentrated in windward and mountain areas. These showers may produce short-lived MVFR ceilings and visibility.
AIRMET Tango remains in effect for tempo moderate turbulence downwind of terrain below flight level 090.
