Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 258 AM EST Sun Mar 01 2020 Valid 00Z Mon Mar 02 2020 - 00Z Mon Mar 09 2020 ...Heavy rain possible into early this week... Upper low over the islands this weekend will weaken by next week as it rotates around an upper high to the northeast. At the surface, models continue to show a ~1040mb high settling well north of the state, and the resulting strong pressure gradient across Hawaii will yield breezy trades into the beginning of next week, with a brief break Wednesday-Friday as heights begin to rise again. A second high pressure center builds north of the state next weekend, bringing a return to gusty winds and showery activity. The upper low will bring a cold/unstable airmass across the region, possibly supporting convection and the potential for heavy snow in some of the higher terrain. Several inches of rain are possible as the upper low passes through, but guidance continues to show the heaviest precipitation staying just offshore to the east. By mid to late next week, with the upper low likely disintegrated and heights rising, rainfall amounts and coverage should decrease. Santorelli
