Kwajalein Atoll Forecast
Wednesday, April 21, 2021
Convective burst from the north aided by the Tropical Upper Tropospheric Trough (TUTT) has pushed through much of Kwajalein Atoll after midnight. The atmosphere is stabilizing from all the rain and embedded thunderstorms earlier this morning. The TUTT will gradually move eastward later today which should keep weather conditions less active today. Plenty of cloud debris will be present this morning from convective activity earlier, however skies will gradually clear later this morning leading to mostly sunny skies by the afternoon. A low level ridge axis will push through westward tonight and will keep Kwajalein Atoll mostly dry which should continue through tomorrow morning. A fairly inactive weather pattern will continue for the rest of the week under general subsidence. Gentle breezes are expected throughout the forecast period. Shower coverage will be <10% today and 10% tonight. Combined seas on the open ocean will be 2-4 feet. NMM
