Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 706 AM EST Fri Jan 09 2015 Valid 00Z Sat Jan 10 2015 - 00Z Sat Jan 17 2015 Both the 00Z/09 parallel GFS and ECMWF continue to indicate that Hawai'i will remain under a zonal ridge for the next week, with the polar jet and its attendant shortwaves and synoptically-forced, deep-layer moisture staying to the north of the island chain. Both of the aforementioned models show less than a tenth of an inch of QPF statewide, save the highest peaks where amounts look relatively paltry as well. Cisco
