NWS Honolulu, HI wrote its last area forecast discussion before the first event at Feb 15, 9:57 AM HST, 51 minutes earlier.
Area Forecast Discussion National Weather Service Honolulu HI 957 AM HST Thu Feb 15 2018 .SYNOPSIS... A wet pattern with mainly light winds will remain over portions of the state through the holiday weekend. Rainfall will be focused across the eastern half of the island chain during the next couple of days as a front and its associated moisture stall over the area. The moisture is expected to drift back toward the west on Saturday and Sunday as a potent upper level low drops over the state. This may produce heavy showers and thunderstorms late Saturday through the Monday holiday. && .DISCUSSION... A slow moving front is focusing rainfall across Maui and southern slopes of the Big Island this morning, though most islands are seeing some shower activity. The front extends northward and wraps into a dissipating surface low located a couple hundred miles northwest of Kauai. An upper level low slowly passing north of the state is triggering a few heavy showers along the front over Maui and along the west coast of the Big Island. Deeper instability to the north is driving scattered thunderstorms along the front just north of the coastal waters northeast of Maui. During the past six hours, generally 1 to 2 inches of rain has fallen across leeward slopes of Maui, and locally heavy showers have been banked up along southern slopes of the Kau and Puna Districts on the Big Island. To the west of the front, moderate showers produced less than a half inch of rain on Molokai and Oahu during this time, while minimal rain fell on most portions of Kauai. Rainfall will remain focused over Maui and the Big Island today, where a Flash Flood Watch is in effect. The front will creep slowly eastward, keeping the deepest moisture and highest rainfall chances across the eastern end of the state. The nearby upper level low will drift northward, maintaining enough instability to trigger a few heavy showers mainly along the front. Across the western half of the state, slowly improving conditions are expected under a westerly, post-frontal flow. Dew points have dropped into the low to mid 60s from Kauai to Molokai, but enough moisture remains to produce additional spotty showers today. The front will stall and dissipate near the Big Island tonight and Friday as the upper level low lifts away from the state. Low level moisture will remain focused across the eastern end of the state, maintaining high shower chances near the Big Island and Maui. Although the upper level low will be lifting out, we still cannot rule out heavy shower development along the old frontal boundary. Across the western half of the island chain, light northwest to north winds will provide drier conditions. A land and sea breeze pattern will promote afternoon clouds and a few interior showers followed by clearing at night. Another round of unsettled weather is looking increasingly likely later Saturday through the Washington's Birthday (Presidents' Day) holiday. The GFS and ECMWF show a potent upper level low dropping over the state from the northwest during the weekend. At the same time, moisture from the dissipated front is expected to drift westward, back up the island chain. This combination could set the stage for heavy showers, thunderstorms, and potential flooding. && .AVIATION... MVFR ceilings and visibility will prevail across most of the state today as bands of clouds and showers along a dissipating front affects the islands. AIRMET Sierra is in effect for tempo mountain obscurations across Oahu to the Big Island, with IFR conditions over the island of Lanai. AIRMET Tango for occasional moderate turbulence from 150 to FL350 is in effect for the entire area. && .MARINE... A weak low a few hundred miles WNW of Kauai will continue to weaken and move E over the next few days. An associated stationary front between Maui and the Big Island will continue to weaken and transition to a trough by Friday, before retreating W over the smaller islands this weekend. Wet conditions are expected for the next several days around the state. Light winds can be expected into the middle of next week. A series of small WNW swells will move through the islands over the next several days. Surf associated with these swells will remain below advisory thresholds. Long term guidance shows a larger and longer period swell arriving next Wednesday, which could bring advisory level surf to the exposed N and W facing shores. High pressure NE of the state will produce short period surf along E facing shores, building this weekend and early next week. Surf could near the advisory levels. No significant S swells are expected. Winds and seas should remain below the Small Craft Advisory levels at least through the middle of next week. && .HFO WATCHES/WARNINGS/ADVISORIES... Flash Flood Watch until 4 PM HST this afternoon for the Big Island, Maui, and Kahoolawe. Wind Advisory until 6 PM HST this evening for Big Island Summits. && Discussion...Wroe Aviation...Foster Marine...Eaton
