Synopsis

Breezy trade winds will continue this week with high pressure slowly tracking eastward. Scant trade showers will favor windward shores and slopes.

Discussion

High pressure to our north continues to rebound as troughing farther to the north lifts out. The pressure gradient remains steep enough to support breezy trade winds across local waters this morning. Ridging aloft keeps our airmass dry and stable, with overnight soundings showing strong inversions near 6300 feet along with PW around 1.2 inches and positive lifted index values. Satellite loop shows patchy broken to overcast low clouds across windward and mauka areas of Oahu and the islands of Maui County, with only scattered low clouds noted on Kauai. Cloud cover decreased significantly across the Big Island overnight, leaving patchy broken low clouds across windward shorelines and lower slopes. Radar shows only isolated light showers associated with this cloud cover.
Models show high pressure to our north will track eastward through the week, with a low shifting the high a bit southward by next weekend. Our weather pattern will change very little through the period, with minor fluctuations in wind speeds and mostly dry and stable conditions continuing. A few windward clouds and showers will occur at times, but no significant rainfall is expected through the week.

Aviation

High pressure and dry air is in place over the region. This should limit any SHRA activity to windward and mauka locations if at all. A strong inversion will keep cigs low allowing for periods of MVFR conds. VFR conds should reign supreme otherwise. Locally breezy trades will continue slightly increasing through the rest of today.
While conds are generally VFR across the area, AIRMET Sierra for mtn obsc may be needed.
AIRMET Tango is in effect for mod turb S and W of island terrain.

Marine

Fresh to strong easterly trades will continue through much of the week, as the surface ridge strengthens to the north. Guidance suggests a potential weakness forming in the ridge northwest of the state next weekend, which could lead to moderate to fresh east-southeast trades.
Surf along south-facing shores will hold around the advisory level today due to a long-period south-southwest swell moving through. No signs of any downward trend at the offshore buoys early this morning with the peak energy holding steady in the 15 to 17 second bands. As a result, the advisory may need to be extended through tonight. A downward trend is anticipated Tuesday through midweek, with mainly a mix of the fading south-southwest swell and a small, medium-period southeast swell. A similar long- period south swell is expected to arrive Thursday night into Friday, then peak late Friday into Saturday.
Surf along north-facing shores will remain up slightly through the first half of the week as small north to north-northwest pulses move through. The next north pulse should fill in today, with a small north-northwest swell arriving Tuesday into midweek. A return to summertime/flat conditions is likely later this week through next weekend.
Surf along east-facing shores should trend up later this week as the trades become established locally and upstream across the eastern Pacific.
