Area Forecast Discussion National Weather Service Honolulu HI 332 AM HST Sat Jul 11 2020

SYNOPSIS. Trade winds will continue through next week as a ridge of high pressure stays far north of the main Hawaiian Islands. The current windy trades will be trending softer as we head into a new week, with speeds reaching light to moderate by Thursday. Showers riding in with the trades will favor the windward and mountain areas with a few drifting into the lee side of the smaller islands.

DISCUSSION. A broad 1027 mb surface high pressure system is located 1040 miles north- northeast of Kauai this morning, moving slowly east. A ridge extends southwestward from the high to just north of Midway Atoll, located 1340 miles west-northwest of Kauai. By the middle of next week, the ridge is expected to drift northward from Midway and get stretched further as the parent high becomes stationary off the west coast. This mean trades will be with us through most if not all of next week.

The trades are currently blowing moderate to strong island-wide, possibly enhanced by the presence of a westward moving weak disturbance located far south of the islands. By tonight, this disturbance will be further away from the islands, resulting in the start of a softening process for the trade winds. By Monday or Monday night, trades will blowing in mainly the moderate range. Light to moderate trades should be in place by Thursday, lasting into Saturday.

The frequency of these trade showers may vary from day to day, depending on the low cloud coverage upwind of the islands. Commonly though, the frequency will increase overnight, then diminish by noon. The windward and mountain areas will take in most of these trade showers, leaving the lee areas of the smaller island dry. Except for the lee side of the Big Island, where the wind sheltered area promote a day time sea breeze that will lead to afternoon/evening clouds and showers.

An upper level low is forecast to drop southwestward to point 500 miles north of the islands by Sunday night. The low then drifts westward through the middle of next week to a point 420 miles northwest of Kauai. The low is currently half way between the islands and the west coast. At this range, it will be closely enough to enhance the trade showers between Sunday night and Wednesday. Models also show two pools of low level moisture with the first coming in Sunday night and a higher dosage on Tuesday. With this said, this boost in trade showers will be enhanced by the upper level low. This is a few days out, and this may change. So, more to come.

Current satellite imagery showers mainly stable stratocumulus clouds passing through the islands from east to west. Radar is picking up a few showers embedded within these clouds, and is drier compared to a day or two ago. So, we expect a relatively dry morning to say two days ago.

AVIATION. High pressure north of the state will keep moderate to locally breezy trades in place through the weekend. Some MVFR cigs/vsbys may periodically affect windward areas, with VFR conditions expected in leeward locales.

AIRMET Tango remains in effect for moderate low level turbulence over and downwind of the terrain. This AIRMET is expected to continue through the weekend.

No other AIRMETs are in effect and none are expected through the daylight hours Saturday.

MARINE. A breezy trade wind pattern will likely hold into Monday before trending down slightly. A Small Craft Advisory (SCA) remains posted for the typically windier waters around the Big Island and Maui County, as well as for windward Maui waters and the Kaiwi Channel. The windward Maui waters and Kaiwi channel SCA goes through this afternoon and the SCA for the waters around Maui County and the Big Island through Sunday. This may need to be extended into Monday.

No significant swells are due well into next week. A mix of background south and southeast swells will continue to produce small surf along south facing shores through next week. Trade wind swells will hold into early next week, producing choppy surf along east facing shores. Additionally, TC Cristina in the far East Pacific could produce a small moderate-period east swell the middle of next week. Surf along north facing shores will remain nearly flat through next week.

HFO WATCHES/WARNINGS/ADVISORIES. Small Craft Advisory until 6 PM HST Sunday for Maalaea Bay- Pailolo Channel-Alenuihaha Channel-Big Island Leeward Waters-Big Island Southeast Waters.

Small Craft Advisory until 6 PM HST this evening for Kaiwi Channel-Maui County Windward Waters.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
