KWAJALEIN FORECAST DISCUSSION
Dry conditions and lighter winds are expected to continue across the Kwajalein Atoll tonight and tomorrow. Subtropical ridging to the north continues to promote a very dry, stable atmosphere that is greatly suppressing shower activity. The surface dew points have also been unusually low over the last few days, adding to the unfavorable conditions for rain and cloud development, although some convection to the south is generating cirrus clouds that may overspread the area tonight and tomorrow. Only occasional stray showers are anticipated, and any that are able to develop are expected to be brief and light. The main subtropical high-pressure system to the north is positioned further to the northeast than what typically occurs in a dry-season pattern. This, along with the lack of a well-organized Inter-Tropical Convergence Zone (ITCZ) to the south, has relaxed the pressure gradient across the RMI, resulting in lighter winds for the weekend. Winds will generally be east-northeasterly in the low-mid teens tonight decreasing a couple of knots tomorrow with higher gusts possible near any showers that do occur. Starting Monday, a fragmented ITCZ may develop and shift northward toward the south-central RMI. This could push a couple of weak atmospheric waves through the Atoll and lead to periods of slightly wetter weather starting Monday night and lasting through the middle of next week. However, this is unlikely to make a significant dent in our rainfall deficit. Shower coverage will be <10% tonight and tomorrow. Combined seas on the open ocean will be 4-6 feet. SMS
