This will likely lead to higher rain chances over windward and mauka areas, since the light background trade wind flow will transport low clouds and showers into these areas. The forecast guidance also shows an increase in low-level moisture. This will cause the trade winds to weaken, so that local nighttime land breezes and afternoon sea breezes may become established starting Monday night. A weak surface trough, which is a reflection of the mid-level feature, may also move into the islands from the east. A mid-level trough to the east of the islands will move west toward the region at the same time. In addition, expect clouds and some showers over the upslope sections of the Big Island each afternoon through Monday.īy late Monday, the surface high will move east, and the associated surface ridge will start to weaken, and drift south closer to the state. Therefore, expect low clouds and minimal shower activity along windward facing sections. The forecast guidance shows that this dry trade wind weather pattern will likely persist through early Monday. Otherwise, skies are mostly clear across most of the state early this morning.
Loops of infrared satellite imagery and radar reflectivity data show scattered low clouds and isolated showers along some windward sections of the islands. In addition, the air mass remains dry over most of the state. The atmosphere remains stable across the state due to upper-level ridging above the region. The tight pressure gradient south and southwest of these features is producing locally breezy trade winds across the state early this morning. A surface ridge extends west-southwest from this high through a point about 360 miles north of Lihue. The trade winds are expected to strengthen again later this week.Ī 1020 mb surface high pressure system is centered near 32N 138W, or about 1360 miles east-northeast of Hilo.

In addition, a disturbance aloft moving into the area plus increased low-level moisture may cause an increase in clouds and showers, including over leeward and interior areas Tuesday and Wednesday afternoons. The trade winds are expected to gradually weaken starting late Monday, which will allow local nighttime land breezes and afternoon sea breezes to develop from Monday night into mid-week. Locally breezy trade winds combined with stable atmospheric conditions will result in a dry trade weather pattern through early Monday.
