Kwajalein Atoll Forecast
Tuesday, April 23, 2024
Tonight, Kwajalein Atoll will see mostly cloudy skies with a few showers, and shower activity may increase up to scattered tomorrow when the nearby Intertropical Convergence Zone (ITCZ) sends a trade-wind trough through the region. Increasing nocturnal instability has begun to promote shower development upstream of Kwajalein Atoll, and periods of light to moderate rain may be expected around the atoll overnight. Cloud cover will mainly take the form of upper-level blowoff alto- and cirrostratus from deep convection which is passing south of the atoll. By tomorrow, a low-level trade wind surge entering the region will likely support a further increase in shower activity. Increased divergence in the upper levels could also deepen convective development, providing opportunities for a couple of downpours or thunderstorms while the trade wind surge remains over the atoll tomorrow and Thursday. Surface winds during this time will generally rise to the upper teens to low twenties, and strong gusts may be expected near showers. By Friday, the trade wind surge will depart, and a drier trade wind inversion pattern will move into the central Marshall Islands, bringing the region back to dry season-like weather with an elevated possibility for advisory-level winds through Saturday. Then, another pattern shift back to less windy but wetter weather may arrive on Sunday. For the near term, shower coverage will be 10-15% this evening but will gradually increase up to 30-40% by tomorrow morning. Combined seas on the open ocean will be 5-7 ft. HWH
