KWAJALEIN FORECAST DISCUSSION
Expected relatively dry weather tonight across Kwajalein Atoll, with fresh easterly winds continuing. Shower coverage will gradually increase overnight into tomorrow as a shallow atmospheric wave from the south may reach the area. A strong subtropical ridge north of the region continues to dominate the local weather pattern. This ridge is pushing drier air into the mid to upper atmosphere, which is limiting shower development around the atoll. It's also tightening the pressure gradient across the Marshall Islands (RMI), resulting in stronger than normal winds. Winds tonight and tomorrow will generally be from the east at 15–20 knots, with higher gusts possible near any passing showers. Meanwhile, a fragmented section of the Intertropical Convergence Zone (ITCZ) is situated over the southern RMI. A portion of this could drift northward overnight, increasing the chance for isolated showers into tomorrow morning. Thunderstorms are not expected, as atmospheric conditions remain unfavorable for deep convection to develop. This overall pattern is likely to continue over the next few days—strong winds due to subtropical ridging, with periodic increases in shower activity tied to fragments of the ITCZ. Heading into the weekend, the ridge is expected to weaken, easing the pressure gradient. This will allow the ITCZ to shift northward and become more organized, potentially leading to wetter conditions and lighter winds. Shower coverage will be <10% tonight increasing to 10-15% tomorrow. Combined seas on the open ocean will be 5-7 feet. CEW
