Surf will be small today, although short-period windswell will affect some south facing shores, especially along beaches of the western end of the island chain. The new west-northwest swell will likely produce surf reaching the High Surf Advisory criteria along exposed north and west facing shores of most islands, including the west facing shores of the Big Island, from Sunday into Monday. Looking ahead, a new north-northwest is expected to arrive late Wednesday, peak Thursday, and then gradually lower on Friday. The new west-northwest swell is expected to arrive over the waters northwest of Kauai later Saturday, is expected to peak on Sunday, and will then gradually subside early next week. Light and variable winds are expected from late Sunday into early next week as a surface ridge builds back in from the east while another ridge builds in from the west. Another high building to the northwest of the region may push another front toward the islands around the middle of next week.

Weather Outlook for Saturday

Warm and humid conditions will persist through the weekend as a cold front moves into the area, then stalls and dissipates Sunday night into Monday over the islands. Increasing rain chances and cloud coverage will accompany the front through Sunday, especially west of Maui County. Another cold front will approach the islands early next week, then move into the area through the mid-week period, which will translate to increasing rain chances once again.

The latest surface analysis and satellite imagery depicted a cold front extending south within one hundred miles west of Kauai that was moving eastward around 30 to 35 mph. Recently animated water vapor imagery showed the short wave trough associated with this front lifting away from the area toward the northeast. A sufficient amount of Q-G forcing associated with this short wave trough, deep-layer moisture and instability continued to support thunderstorms developing along and ahead of the front early this morning, that were mostly located well northwest of Kauai and Niihau across the offshore waters. A few storms, however, were approaching the northwest Kauai waters. As a result, the morning package will include a slight chance of thunderstorms across these waters through the morning period.

Through Sunday night, The latest numerical guidance has initialized well with this synoptic pattern and generally remains in good agreement through the weekend. Outside of the potential for a storm or two moving into the northwest Kauai waters this morning, as previously mentioned, all sources indicate the better dynamics and forcing for ascent will remain well north and northwest of the islands as the upper trough continues northward and away from the region, which should limit thunderstorm chances across the islands through the weekend. Rain chances and cloud coverage, however, will steadily rise today as the weakening cold front moves into the area. The best rain chances are expected across Kauai and Oahu through tonight. The front is expected to weaken and slowly dissipate west of Maui County Sunday and Sunday night.

Monday through Friday, The extended deterministic and ensemble guidance remain in decent agreement Monday through Tuesday and depict a weak surface ridge of high pressure building north of the islands in the wake of the previously discussed front. Slightly drier air and light to moderate northerly winds will fill in across the smaller northwest islands through this time. Some residual moisture associated with the dissipating frontal boundary previously discussed will likely remain in place across the central portions of the islands.

The progressive pattern is forecast to continue through the mid-week period as a series of short wave troughs dig southward across the central Pacific and drive another cold front toward and over the region Wednesday through Friday. Forecast uncertainty begins to increase through this period as the models begin to introduce some differences. Regardless of these differences, increasing rain chances and cloud coverage will likely be the result through this period, which are supported in the current forecast package.
