Based on data through 2:00 pm Mar 29 2015 HST

Latest water vapor satellite imagery show an upper level ridge located over the main Hawaiian islands gradually migrating E. Also, an upper level low continues to support an area of overcast layered clouds and thunderstorms centered around 06.9°N 141.1°W or 1200 miles SE of the Big Island. Cloud tops in these thunderstorms are reaching 43 thousand feet. Meanwhile, a surface cold front is located about 230 miles NW of Kauai with an associated 120 mile-wide cloud band extending from 30.0°N 153.7°W to 26.7°N 161.8°W to 23.0°N 180. Cloud tops in this band range from 12 to 16 thousand feet, highest near 30°N.

Closer to the islands, broken to overcast low clouds with a few showers cover most areas of the Big Island below 7 thousand feet, except between the Volcano park and wood valley where mostly clear skies prevail. On Maui county, broken to overcast low clouds can be observed across much of the central valley in Maui, the leeward slopes of Haleakala, windward coastal locations from hamoa to keanae, the W Maui mountains and over the E Molokai mountains. Scattered to broken low clouds linger over leeward Lanai. On Oahu, overcast low clouds and scattered showers cover the Koolau mountains and windward locations from Waimanalo to Kahuku. Broken low clouds prevail over most of the rest of Oahu, including the Honolulu metro area. On Kauai county, broken to overcast low clouds cover most of Kauai, except for patches of mostly clear skies between Kalaheo and Hanapepe.

Elsewhere, N of 10°N, mainly scattered to broken cumulus and stratocumulus prevail across the area N of 10°N between 140.0°W to 180 and E of the aforementioned cold front. Individual cloud elements are moving to the W at 15 to 20 mph, turning to the N and NE immediately ahead of the front between 150.0°W and 160.0°W. Mainly broken stratocumulus clouds prevail W of the front with cloud motion to the s/sw at around 20 mph.

Far S of the islands, deep convection with embedded thunderstorms extend along the intertropical convergence zone along 05°N between 165.0°W to 180. Highest cloud tops in these thunderstorms are reaching 50 thousand feet.
