Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 812 AM EDT Thu Aug 22 2019 Valid 00Z Fri Aug 23 2019 - 00Z Fri Aug 30 2019 Generally light trades on Friday will increase for the weekend into next week as surface high pressure moves eastward to the north of the area. Aloft, a mid-level upper low will push westward to the south of the upper high to rejoin the westerlies near 40N early next week. Upper ridging will weaken through the week as troughing deepens in the mid-latitudes between Hawai'i and Alaska. Models/ensembles generally agree on keeping deep tropical moisture along the ITCZ, with any protuberances likely east or west of the Aloha state by several hundred miles. However, model consistency has been rather poor given the weak nature of such systems, so confidence is low in any specific solution. Generally expect a typical trade wind pattern next week with scattered windward/mountain showers. Fracasso
