Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 148 AM EST Wed Feb 05 2020 Valid 00Z Thu Feb 06 2020 - 00Z Thu Feb 13 2020 An upper low moving towards Hawaii on Wednesday will drive a cold front southward across the island chain into Friday. This will bring scattered to widespread showers and a few thunderstorms. A much cooler airmass, with gusty northerly winds, will follow behind the front persisting into the weekend. Models continue to show decent agreement that a second, possibly stronger, upper level low will drop towards the state early next week. Depending on proximity of this low to the islands itself, at least unsettled conditions are likely to continue through the middle of next week. Santorelli
