Kwajalein Atoll Forecast

KWAJALEIN FORECAST DISCUSSION
Shower chances will remain low across the atoll this afternoon. Stable subtropical pressure remains dominant over much of the RMI, and sinking air along with limited surface forcing continue to inhibit shower development. Winds will generally be east-northeasterly with gentle speeds around the middle single digits throughout the day. Although shower chances will remain about the same through the evening, a tightening pressure gradient will increase average wind speeds towards the low teens tonight, and winds may remain around this level for the next several days. Later tonight, a shallow trough passing to the south will clip the atoll, providing a weak source of lift to slightly amplify shower chances overnight into tomorrow morning. Trough passage may also cause a wind shift to more east-southeasterly winds tomorrow. Late Friday into Saturday morning, another shallow atmospheric wave may once again bring isolated shower activity to the atoll, but outside of these periods, the workweek should see the dry high pressure pattern persist. Shower coverage will be <10% today and tonight, increasing to 10-15% overnight. Combined seas on the open ocean will be 2-4 feet. HWH
