Looking Ahead 

The leading edge of a slow-moving front will remain near the Big Island through today. When combined with a disturbance high in the atmosphere conditions are expected to be quite messy bringing widespread showers, strong winds, lightning, thunderstorms, hail and flooding conditions. Locally heavy showers are also possible. The threat for this potentially severe weather exists through Wednesday as the disturbance flaring up thunderstorms becomes a cutoff low and lingers in our area. The front is expected to fall apart on Tuesday but a surface low might develop which could suck moisture out of the south and up over the islands. The forecast is still a bit uncertain when it comes to the surface low developing and will be tweaked as it becomes more certain.
