Looking Ahead
Light-east southeast flow will continue through the day Thursday. A somewhat unstable airmass along with sufficient moisture at the surface will likely result in some moderate to heavy showers at times through Wednesday. Trade winds will briefly strengthen from Thursday night through Friday night. An increase in showers and humidity is expected this weekend as remnant moisture from a former tropical cyclone moves across Hawaii this weekend.
