KWAJALEIN FORECAST DISCUSSION
Expect increased shower activity today as a trade wind trough moves across Kwajalein Atoll. The Intertropical Convergence Zone (ITCZ) has become somewhat fragmented near the RMI, allowing trade wind troughs to become the primary driver of rainfall over the next few days as the ITCZ slowly reorganizes. A stray thunderstorm or two is possible, supported by relatively cool upper-level temperatures. Deep pockets of moisture are moving through the region, increasing the possibility of heavy showers at times. Winds will generally be from the east-northeast, ranging in the mid-teens, with gusts near heavier showers potentially shifting to the east-southeast and reaching up to 30 knots. As this initial trade wind trough moves out of the area this evening, both wind speeds and shower activity are expected to decrease overnight. However, conditions will likely become active again early Sunday morning with the arrival of another trade wind trough. Overall, the weekend is shaping up to be quite wet, with additional trade wind troughs forecast through the weekend and into early next week. Shower coverage will be 15-20% today, decreasing to around 10% for tonight. Thunderstorm coverage will be <1% today and tonight. Combined seas on the open ocean will be 5-7 feet. MDM
