EVENING FORECAST FOR

KWAJALEIN FORECAST DISCUSSION

Widely scattered shower activity will continue this evening, but shower coverage will begin to decrease tonight as a localized area of wind speed convergence exits Kwajalein Atoll. The main driver of last week’s weather pattern has been the Intertropical Convergence Zone (ITCZ), which has now been pushed far south of the atoll by the subtropical ridge, spreading heavy showers over parts of the southern RMI. Locally enhanced trade wind convergence will continue to support moderate shower activity this evening, but without the abundant mid-level moisture brought by the ITCZ, showers will tend to be light to moderate and will generally remain over the southern part of the atoll. Conditions will be unfavorable for thunderstorms as cells will remain too shallow for lightning. Shower coverage will decrease after nightfall as the localized convergence area moves downstream of Kwajalein Atoll. Winds will be east-northeasterly to east-southeasterly in the low to middle teens, with gusts around the mid-20s possible as dissipating showers move in. Tomorrow afternoon, the intensifying subtropical ridge will cause the pressure gradient to tighten over the RMI, increasing surface winds and decreasing the chances for showers. Relatively drier weather may continue through about Wednesday when another active weather wave could approach the atoll. Shower coverage will be 20-25% this evening, decreasing to 10-15% late tonight, then remaining around 10-15% tomorrow. Combined seas on the open ocean will be 4-6 ft. HWH
