Winds Statewide in a glance ...just go HERE(this link is also the 4th drop down under weather)
Apr 17, 2014 3:30 AM HST
High pressure north of the area will keep moderate trades across the islands through the next couple of days. Winds are expected to increase during the upcoming weekend and into early next week as reinforcing high pressure develops north of the island chain. Clouds and showers will continue to favor windward and mountain areas. Leeward areas of the Big Island will see increased clouds and showers each afternoon and early evening.
Strong surface high pressure centered far N of the main Hawaiian islands is keeping the area under a trade wind weather regime. In the meantime, water vapor imagery still depicts a persisting weak upper level trough over the area, which may keep enhancing the trade showers especially at night.
Short range model solutions indicate a gradual reduction of pressure gradients during the next couple of days as the high N of the area migrates E and weakens. This will likely bring a decrease in trade wind speeds, which will remain moderate through the rest of the work week. The long range model solutions suggest an even stronger high pressure system building behind the current one, which intensifies as it moves N of the islands by Saturday. This should bring back stronger trades with breezy conditions returning during the upcoming weekend.
In general, expect trade wind showers to continue through the rest of the forecast period with rainfall focusing over windward and mountain areas. Only exception will be the leeward side of the Big Island where afternoon clouds and showers are expected as onshore develops each day.
A small swell from the west northwest will peak below advisory levels later today. No other significant swells are expected.
