A relatively strong surface high will dominate Hawaiian weather for the next week. The 1032 mb high is located about 1100 miles northeast of the state and will continue a slow northwest drift through tomorrow. As a result, trade winds will be locally strong and gusty in the short term. Subsidence ahead of an advancing upper level low led to gusty downsloping winds early last night, and a wind advisory remains in effect for all islands. As the upper low passes overhead today and tonight, advisory level wind gusts will likely be isolated and confined to ridge tops and areas to the lee of terrain. The current forecast calls for advisory level winds to persist into Thursday, and we will take a closer look at the likelihood of the stronger winds holding that long. The upper level low will lead to an increase in showers today, mainly for the eastern end of the state. The upper low is currently centered about 65 miles southeast of Hilo and is travelling to the west near 15 mph. Even though moisture is limited in the trade wind flow, this feature has managed to enhance showers moving onto windward Big Island slopes, where one quarter to one half of an inch of rain has fallen in the past 12 hours. Expect the enhanced rainfall to persist into the evening on windward Big Island and possibly Maui, and leeward Big Island slopes will see an increase in showers this afternoon. Across the rest of the state expect modest windward showers and dry leeward conditions. A stable and relatively dry trade wind flow will redevelop state-wide on Thursday as the upper low departs. Precipitable water values in the upwind trade wind flow look to be below normal, and with a strengthening inversion in place, rainfall will be on the lighter side and largely confined to windward slopes. Breezy and gusty trades will hold on through the holiday weekend then decline next week. The high will remain anchored in place through Monday then begin to weaken and move to the southeast on Tuesday. As the high weakens trade will gradually decline to moderate strength.
