Winds Statewide in a glance ...just go HERE(this link is also the 4th drop down under weather)
Mar 11, 2014 3:54 AM HST
Trade winds will increase across the state this week with clouds and showers favoring windward and mauka areas. A cold front will reach the islands Friday night, bringing strong, gusty trade winds through the weekend.
Showers have diminished across the state overnight with a batch of heavy rain departing south of Big Island waters early this morning. Dew points across the state have dropped 3-5 degrees since yesterday morning and all indicators point to a drier weather regime over the next few days.
A front stalled north of Kauai will keep winds light to moderate today. Partly cloudy skies will pepper the islands with limited showers popping up along the windward slopes. The front will dissipate today allowing high pressure to build from the north. Trade winds will increase through midweek in response to the building high pressure.
A progressive pattern will push weather features quickly from west to east through the forecast period. The current high pressure will move into the east Pacific Wednesday as a cold front pushes across the dateline behind the high. The tail end of the front is forecast to reach Kauai Friday evening bringing showers to the smaller islands Friday night. Strong trade winds will fill in behind the front bringing gusty winds and fast moving showers. Windward areas will be the main focus of rain, but the smaller islands will see showers blow over the mountains to leeward locations at times. The mid and upper atmosphere look to remain stable through the period so showers that do form will remain shallow.
Strong trade winds will diminish next week as the high pressure generating the winds moves into the east Pacific and another cold front crosses the dateline.
Weak trade winds across the Big Island will spread across the remainder of the state by afternoon. Scattered showers and isolated MVFR conds can be expected across eastern and northeastern slopes but high VFR expected all other areas. Airmet sierra for mountain obscuration over windward Big Island will likely be cancelled after sunrise but conditions could redevelop this evening.
Trade winds will approach small craft advisory levels Wednesday in the typical windier waters around Maui county. Winds will strengthen further Friday and over the weekend with the possibility of gales in the Alenuihaha channel. A SCA is likely across the Hawaiian waters.
