Mar 09, 2014 4:00 AM HST
Moderate trade winds will persist this week, strengthening next weekend. Clouds and showers will favor windward and mauka areas today with brief passing showers making it onto leeward areas. Wet weather will continue for windward Maui and Big Island through Tuesday. Drier conditions expected for all areas Wednesday through Friday morning. Another frontal system will approach the islands late Friday into the weekend.
A fair amount of clouds and showers remain across the state this morning. Moderate-strength trade winds are focusing most of the rainfall onto windward and mauka areas, with brief passing showers making onto leeward sides of the smaller islands. The clouds and showers are due to remnant moisture from a front that moved southeast of the Big Island overnight. The atmosphere is stabilizing with an 8000 foot inversion and precipitable water value of 0.95 inches on the Lihue sounding this morning. Moisture is a bit deeper at Hilo.
Expect the clouds and showers to carry through much of the day today for windward and mauka areas. Leeward areas should begin to see decreasing showers and partly sunny skies by afternoon, except for leeward Big Island which will receive typical afternoon clouds. By tonight / Monday, expect most of the showers to slide east and focus on the windward sides of Maui and the Big Island. The trade winds will continue to push moisture across Maui and the Big Island through Tuesday. A temporary weakening of the trade winds is expected Monday and Monday night as another front passes north of the state, but this will be the only impact to our weather.
An upper trough will pass just northeast of the Big Island Tuesday and will provide a bit of enhancement to the showers. Afternoon convection across the leeward Big Island slopes will be possible Monday and Tuesday, while the associated jet stream with the upper trough may bring windy conditions to the Big Island summits. Moderate trades will fuel drier and more pleasant conditions to the western part of the state Monday and Tuesday, then spread to all islands Wednesday and Thursday.
Another front and upper trough will pass over the state Friday through Saturday night, bringing a higher chance for rain. A strong surge of northeasterly trade winds will build in right behind the front. Assuming models are correct, this may spark a wind advisory for some or all areas of the state beginning Friday night or Saturday. Winds will mix with showers providing rather blustery conditions through the weekend.
