Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 314 AM EDT Mon Aug 17 2020 Valid 00Z Tue Aug 18 2020 - 00Z Tue Aug 25 2020 A weakness aloft will slowly move across the area from east to west Tue/Wed, with a slight decrease in trades and an increase in showers. This low may settle just to the west of the region as periodic higher moisture axes push through. This could extend a more showery period through the week as both the ECMWF and GFS show a surge in PW values from the southeast to around 2 inches Wed into Thu for at least the Big Island and into Maui. Once this passes through, lower PW values between 1.25-1.50 inches will be common, along with more typical trades that may trend higher by next Sun/Mon. Fracasso
