Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 826 AM EDT Mon Jul 08 2019 Valid 00Z Tue Jul 09 2019 - 00Z Tue Jul 16 2019 A broad subtropical ridge will be anchored north of Hawai'i while remnants of what was tropical cyclone Barbara drifts westward. Precipitable water values will rise above 2 inches and this will bring a period of enhanced rainfall to the islands, especially on the East and South sides of the islands. The best potential for heavier showers is for the Big Island and this will elevated the risk for flash flooding. Otherwise, typical trade wind induced showers can be expected through the upcoming week. Campbell
