Summary

A high pressure ridge will remain in the north of the state for the remainder of the week with moderate to stormy trade winds forecast through Friday. Minor disturbances at altitude will keep short transient showers in the forecast until at least Thursday, affecting mostly windward and mountainous areas. The ridge seems to weaken from late Friday through the weekend with decreasing trends in our wind speeds.

discussion

Satellite imagery from this morning continues to show a large high pressure ridge north of the region with a low pressure system near the date line. Radar images show that brief showers mainly affect windward and mountain areas, with only the strongest showers reaching some leeward locations. The amount of precipitation remains low at most locations.
Short-term weather models suggest weak intermediate-level disturbances sweeping the islands, with the forecast holding some showers through Thursday. The cross-sections of the weather model show the subsidence inversion, which limits vertical cloud development and ranges from 6,000 to 8,000 feet in elevation for most of the week. This inversion height is high enough for short passing showers, which favor windward and mountain areas with trade winds. Drier conditions are forecast for areas protected from the wind. There is a higher probability of rain in the typical night to early morning hours.
The high pressure ridge north of the state will weaken by late Friday due to this approaching front, and wind speeds will drop into the light to medium range by the weekend. Lighter winds in this area are expected during the night hours. The long-range guidance keeps clouds and showers with this dissipated front too far north of the Hawaiian Islands, which limits the increased precipitation activity with this system.

aviation

The high pressures in the north of the state will allow moderate east-northeast trade winds to persist for the remainder of the morning and into the afternoon. Therefore, scattered showers will mainly be limited to windward slopes and coasts. This activity may involve short periods of MVFR caps and visibility.
AIRMET TANGO remains in effect for southwest to west of the mountains due to tempo-wise turbulence below 8,000 feet.

marine

High pressure north of the islands will hold moderate to strong trades during the week. A Small Craft Advisory (SCA) now applies to the waters around Maui and Big Island until 6:00 p.m. on Friday. This SCA will likely need to add additional waters Tuesday through Thursday.
The current south-southwest swell will continue to subside tonight through the weekend ahead, followed by mostly southern background swells and below normal surf for south-facing banks. Aside from a little trade wind swell wrap, surfing along the north coast will be flat this coming weekend. The only noticeable surf over the next 7 days will be along the east facing coastline, where sustained moderate to strong trades will keep the surf near the summer average.

HFO watches / warnings / notices

Small Craft Advisory until Friday 6:00 p.m. HST for Maalaea Bay, Pailolo Channel, Alenuihaha Channel, Big Island Leeward Waters, Big Island Southeast Waters.
