034 FXHW01 KWNH 230736 PMDHI Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 235 AM EST Sat Nov 23 2024 Valid 00Z Sun Nov 24 2024 - 00Z Sun Dec 01 2024 A surface ridge of high pressure stretching west to east across Hawaii will lead to dry conditions over the weekend, with precipitable water values generally below an inch and dewpoints into the 60s, and few if any showers. The ridge will also promote light winds, allowing land and sea breezes to form. By late Sunday into Monday, a weak front is forecast to approach Kauai and move southward as it dissipates. Some weak moisture convergence along/ahead of the fronts and slightly moistening PWs could lead to a few more showers in the western islands, but with no widespread heavy amounts. Winds should also shift to be from the north behind the front, but likely remaining on the weak side. By the latter half of next week winds are forecast to turn back to the more typical easterly direction and strengthen a bit to moderate levels as a weak surface ridge sets up to the north. Generally dry conditions are likely to continue, but any showers that do develop would favor windward and mountain areas. Tate $$
