SYNOPSIS

A tight pressure gradient from a surface ridge to the north and Tropical Storm Pena passing far to the south will generate breezy trades through tonight before gradually easing Monday to more typical moderate to locally breezy levels. Trades will strengthen again to possibly locally windy levels Wednesday through Thursday as a strong surface high builds north of the state. Dry and stable airmass will limit clouds and showers mainly along windward and mauka areas. A band of moisture may move from north to south across the state during the second half of the week bringing an uptick in showers to windward areas.

DISCUSSION

Latest satellite imagery shows a pocket of low level clouds and showers just east of Oahu through Big Island. Radar shows most of the embedded showers are light and expected to continue to impact mainly windward areas but could spill over to leeward areas of the smaller islands at times. Rainfall totals are expected to remain modest as inversion heights slope from around 5,000 ft from Kauai to 6,000 ft to Hilo and available moisture is near to below average under a dry and stable atmosphere. Showers will trend down during the day tomorrow and winds will gradually ease to more typical moderate to locally breezy strengthens through Tuesday.

A strong surface high will sink just north of the state Wednesday, strengthening trades back to breezy to locally windy levels. A band of moisture embedded within the trade wind flow will track south over the state Wednesday night through Thursday bring an uptick in showers to exposed windward areas. The high will gradually weaken into the weekend allowing trades to ease back to more typical moderate to breezy speeds while pockets of moisture continue to focus along windward and mauka areas.
