Brisk island trades will prevail over the next couple of days in
tight pressure gradients underneath strong high pressure to the
north of the state. A relatively dry airmass suggests that daily
windward/mountain-focused showers should be limited. Rainfall
potential will increase Friday through the weekend as a favored
guidance composite decreases heights aloft as an upper ridge to
the north of the state weakens in response to digging trough
energies. Lower atmospheric inverted troughing will develop over
the state as high pressure shifts more into the eastern Pacific
and as upper trough and possible closed low energies settle over
Hawaii and increase instability. Trades should tend to veer and
tap deeper moisture to fuel widespread showers/thunderstorms that
may linger into early next week, especially across the eastern
islands.
