HONOLULU (KHON2) - As we head into the weekend, atmospheric stability will increase as mid level ridging begins to build in from the west, with increasing subsidence and mid level temperatures.
At the surface, a weak front will approach from the northwest, which will effectively weaken and veer
the surface flow out of the east- southeast as the surface ridge is nudged south and east.
This lighter east-southeast surface flow will allow for sea breeze development each afternoon.
With the increasing stability aloft and drier air filtering in from the east, sea breezes will likely increase cloud cover over leeward areas during the afternoon periods, but any shower development will likely be limited.
For the same reasons, shower activity will also be limited over windward areas through early next week.
The weak front will dissipate as it nears the state, leaving a diffuse boundary with some remnant moisture northwest of Kauai on Sunday night into Monday morning.
Some of that moisture may edge into the western end of the state during that period and increase the chance of showers across Kauai.
In addition, another batch of low level moisture riding into the eastern end of the state may bring an uptick in shower activity across the Big Island Sunday into Monday.
However, ensemble guidance is leaning towards keeping most of the state dry. ...read more read less
