High pressure northwest of the Hawaiian Islands will bring gusty northeasterly trade winds to the terminals through the TAF period. This will allow for mostly VFR conditions to prevail with brief MVFR trade wind showers. Showers will be focused across mainly windward and mountain areas, although a few showers are anticipated to make it into leeward areas. Northeasterly winds will gust to 20-30kts for the terminals at times this afternoon, decreasing slightly overnight, before returning again on Wednesday. Stronger winds with gusts to 45 kts can be expected across the channels, over higher terrain, and across mountain valleys.

Aside from trade wind showers, mid-level instability will bring the possibility of an isolated thunderstorm with snow showers for the Big Island summits this afternoon.

With gusty winds, AIRMET Tango for turbulence below 8,000 feet is anticipated to remain in effect over and immediately south through west of mountains through tomorrow.
