KWAJALEIN FORECAST DISCUSSION
Isolated showers and a few stray thunderstorms are expected tonight into tomorrow as a fragmented Inter-Tropical Convergence Zone (ITCZ) continues to influence the region’s weather. A trough embedded within the ITCZ is currently moving through the central Marshall Islands and will be the primary trigger for tonight’s shower activity and potential thunderstorms. Thunderstorm potential will be elevated due to cooler temperatures aloft and favorable upper-level dynamics that support deep convection and lightning development. Winds will remain light, generally in the mid-single digits, but will shift to the north-northeast by tonight and gradually increase into the upper-single digits ahead of another approaching trough. This next system may bring a renewed round of showers and thunderstorms by Sunday morning. Following the trough's passage, the ITCZ is expected to weaken and lift northward. This will likely usher in calmer, doldrum-like conditions with occasional isolated showers through the remainder of the weekend and into the first half of the upcoming work week. Shower coverage will be <10% by tonight, increasing to 15% overnight into tomorrow. Combined seas on the open ocean will be 2-4 feet. CEW
