One last humid day is in store today as trade winds gradually build in from east to west. Dew point temps are down a couple of degrees since yesterday, but they remain rather high in the 73 to 76 degree range as the tail end of the humid air mass remains over the islands. During the last couple of hours, easterly trade winds have picked up from Molokai eastward, and a line heavy moderate to locally heavy showers pushing onto windward Oahu appears to be the leading edge of the rebuilding trades. Farther west, a surface trough, marked by thunderstorms a hundred miles north of Kauai and Oahu, is cutting off the trade winds this morning. As this feature weakens, trade winds will filter in. Rebuilding trades will focus clouds and showers across windward slopes today, but afternoon clouds and chances for spotty afternoon showers will linger on Kauai and Oahu. Some showers could be briefly heavy due to waning instability created by a weakening upper level trough centered a few hundred miles northwest of Kauai. As this feature weakens, so will the surface trough north of Kauai and Oahu. This process will allow trades to surge back in this afternoon and tonight, ushering the humid air mass off to the west. A typical summer time trade wind regime will become established tonight with winds becoming locally breezy on Wednesday. Mid to upper level ridging will gradually build, creating an inversion around 6000 to 8000 ft that will stabilize the atmosphere. Trade winds will pick up a notch as a 1032 mb high remains parked about 1400 miles north of the state. This will pattern will focus clouds and modest showers over windward slopes. Leeward areas will be rather dry, with the exception of the Big Island slopes where afternoon clouds and showers will develop.
