SYNOPSIS
An approaching upper level trough to the west, with deepening moisture ahead of this feature, will introduce regionally unsettled weather the next several days. Trade winds will remain the dominant wind pattern so expect the highest rainfall from passing showers to better focus along windward areas.



DISCUSSION
IR satellite depicts a jet stream streaming over the eastern half of the islands this evening. A high 1.8 inch pwat moist southern air mass streaming up within the jet has moistened the regional column to above 15,000 ft this afternoon. The atmosphere is marginally unstable but, with the divergence brought on by the northeast-exiting jet and deep tropical moisture, the threat for thunderstorm activity remains alive but only with isolated coverage. The possibility of isolated thunderstorm with this evolving situation will bear close monitoring tonight. A Winter Storm Warning in is effect of the Big island summits through Monday afternoon for frequent periods of snow and freezing rain.
Temperatures at the summits of the Big Island are right at freezing, and are expected to fall several degrees below freezing tonight. Winds are generally light at the summits, but the moisture moving in and below freezing temperatures support the Winter Weather Warning that is in effect there through Monday afternoon. There is some mention of winter weather on Haleakala in tomorrow night's forecast. However, at this time, temperatures will likely be too warm and moisture not deep enough over Maui to support any significant frozen precipitation accumulation.
Rainfall chances will definitely be higher over windward Mauna Kea and Mauna Loa and Haleakala's slopes through Tuesday night.

High pressure to the northeast is moving away and will be replaced by a new high to the north of the islands tomorrow. This will result in strengthened trades Monday night and Tuesday.
Trades will return to locally windy levels for the remainder of the week. The upper level trough moving over the islands from the west will introduce more instability to the islands. Therefore, there is a higher possibility of thunderstorms and higher rainfall for primarily Kauai and Oahu from Monday night through Tuesday morning. The trough is expected to sink further south across the central islands Tuesday. This will help enhance areawide trade wind showers throughout the remainder of the week.

AVIATION
Moderate trade winds will increase to breezy levels on Monday as a high pressure system builds in north of the state. A low level trough moving from east to west across the islands and an upper level trough and subtropical jet stream will enhance showers for all islands favoring windward and mountain areas. Periods of MVFR/IFR conditions with low ceilings and visibility in showers are expected mainly over windward airfields lasting through Monday. The eastern slopes of the Big Island will see more frequent MVFR/IFR conditions over the next 24 hours.

AIRMET Sierra remains in effect for mountain obscuration along windward slopes of Kauai, Oahu and Big Island due to clouds and showers. This AIRMET will likely be needed into Monday.

AIRMET Tango is in effect for moderate leeward mountain wave turbulence over all islands due to breezy winds. This AIRMET will likely be needed through today. The subtropical jet will also bring the potential for moderate high level turbulence over and to the north and east of the state later today.



MARINE
High pressure to the northeast is moving east and will be replaced by a new high to the north of the state Monday keeping fresh to strong trade winds in place over the coastal waters. A Small Craft Advisory (SCA) is out for all waters through Monday afternoon due to a combination of winds and seas. An upper level trough moving through the islands from the west will keep the potential for instability and thunderstorms through tonight.

A moderate, medium period north (010 degree) swell came in larger than guidance has peaked this afternoon and will gradually ease tonight into Monday. Given the northerly direction of this swell, minor surges remain possible within north-facing harbors tonight into early Monday, especially at Kahului and Hilo. See the latest Marine Weather Statement for further details.

In addition to the gradually declining north swell, a moderate, medium to long period northwest (310 degree) swell is currently moving through the islands and will peak tonight through Monday morning. This swell will keep surf elevated along exposed north and west facing shores, peaking near or slightly below High Surf Advisory levels. This northwest swell will begin to gradually decline Monday afternoon through the rest of the week, with surf along north and west facing shores slowly declining.

Choppy, moderate trade wind swell will remain in place throughout the next several days, keeping surf rough along east-facing shores. Surf along south facing shores will remain small this week with no significant south swells expected.
