Good Wednesday morning.  Here we go again!  We are tracking another round of rain and possible heavy pockets of showers.

Our models and the radar show, periods of unsettled weather along with humid conditions to continue through at least Thursday. Your First Alert team is tracking a front along with moisture from the southwest that is meandering near and over the state.

On top of that, we are keeping an eye on an upper level weather disturbance that has the potential to periods of heavy rainfall across the western end of the state Wednesday. 

The slow-moving front will slide down the island chain Thursday night into the weekend, bringing periods of wet weather to portions of the state. 

This unstable air mass may trigger a thunderstorm or two for parts of Kauai and Oahu and after daytime heating, a flash of lightning may be seen over parts of the Big Island Wednesday afternoon.  Yesterday, this activity was over Puna where there were several thunderstorms roaring over the island.

The weather continues to remain interesting, as we track a deep moist southwesterly flow that could keep scattered to numerous showers across the islands through Thursday, and some locally heavy downpours can't be ruled out. Additionally, daytime heating may result in an isolated thunderstorm or two developing over the Big Island Thursday afternoon again.

A small northwest swell is expected to arrive Wednesday and continue through Thursday, then gradually subside on Friday. Surf along north and west facing shores will remain below advisory levels. Choppy, short period surf is expected along most south facing shores Wednesday due to the southwest winds. A small, but long period south swell is forecast to arrive early Friday.

Have a safe and wonderful Wednesday.  Make sure to keep track of the radar throughout this week.
