Area Forecast Discussion National Weather Service Honolulu HI 347 PM HST Wed Apr 1 2020

SYNOPSIS. Deep low pressure developing far northwest of the state on Thursday will cause trade winds to veer out of the southeast, leading to a somewhat unstable land and sea breeze regime that will produce spotty showers, some briefly heavy, over the islands during the afternoon hours. Winds will turn more southerly on Friday and the weekend, likely drawing up deeper moisture over the islands and fueling more shower activity. A front associated with the low is expected to maintain wet conditions over the state on Monday and Tuesday.

DISCUSSION. Weak trades have been overpowered by sea breezes this afternoon, while an upper level trough overhead is maintaining unstable conditions. As a result, heavy showers and isolated thunderstorms have flared over interior sections, mainly on the Big Island and also on Oahu, where a weak surface trough is passing by. Expect heavy shower activity to taper off late this afternoon, with showers lingering on the Big Island a bit longer. The weak trough will move westward, bringing a few showers to windward Kauai.

For tonight, weak trades will hang on with modest showers favoring windward slopes. Deep troughing at the surface and aloft will continue to dominate across the Pacific north of the state, splitting a pair of strong surface highs and suppressing the local trades. leeward shower activity will clear out quickly by evening. With available moisture limited, modest showers will favor windward slopes, even though conditions will remain unstable.

Trade winds will gradually shift out of the southeast on Thursday as an area of deep low pressure develops in the trough far northwest of the state. While showers will favor east and southeast slopes, a land and sea breeze regime will dominate over leeward areas, leading to clouds and spotty afternoon showers, some briefly heavy. Aside from the interior slopes of the Big Island, thunderstorms are unlikely.

As the deep low settles about 850 miles northwest of the state on Friday, shower chances will increase as winds shift more southerly and draw deeper moisture over the islands. The state will be under the outer portion of the upper level trough associated with the low, likely leading to enough instability to trigger isolated heavy showers. Thunderstorms cannot be ruled out but confidence is not high enough to include them at this time. As a front associated with the low edges closer to the state on Sunday, shower chances should increase, especially across the western end of the state. In addition, the southerly flow will push dew points up to around 70, bringing an increase humidity that we have not experienced for a while.

On Monday and Tuesday, the front, or what is left of it, is expected to push across portions of the island chain, stalling perhaps as far east as Maui during the middle of next week. The latest runs of the GFS and ECMWF have come into better agreement on this scenario, but somewhat high uncertainty remains.

AVIATION. Weak flow will persist this afternoon as a trough passes over the islands. Sea breeze formations along the coast have allowed for shower development over the interiors of the islands. Enough instability exists for isolated areas of heavier showers or thunderstorms.

Most activity is expected to dwindle by sun down. Tonight, light winds will ensue state wide with a few showers along the windward coasts and slopes.

No AIRMETS are in effect at this time.

MARINE. A surface high far northeast of the area is maintaining easterly trade winds across Hawaiian waters, but a trough over the eastern offshore waters will keep the winds gentle to locally fresh though Thursday.

A low south of the Aleutians is forecast to move south and approach the area, causing winds to veer out of the southeast beginning Thursday. Winds will weaken over the western part of the coastal and offshore waters but winds may strengthen over eastern waters, especially where the southeast flow accelerates around the Big Island and Maui. A convergence band associated with the low will likely move over the northwest offshore waters Saturday, strengthening south winds over the western waters and bringing another chance of thunderstorms.

The current small northwest swell will slowly subside through Friday night. A new swell building Saturday will produce moderate surf along north and west facing shores over the weekend, but is expected to remain well below the advisory threshold. Swells from the southern hemisphere will maintain elevated surf along south facing shores through tomorrow, but should remain just below advisory levels. Swells from the distant southeast Pacific will be partly blocked by the islands of French Polynesia, but should be enough to produce small surf through the rest of the week. Surf along east facing shores will remain up through midweek due to an upstream fetch, despite the trades relaxing locally, then subside by the end of the week.

HFO WATCHES/WARNINGS/ADVISORIES. None.
