HONOLULU (KHON2) – Expect weakening trade winds to make way for prevailing light winds that will persist through the remainder of the work week.
Upper ridging across Hawaii combined with a relatively dry environment will result in little rainfall expected over the next several days.
Daytime sea breezes and nighttime land breezes will lead to interior cloud build ups throughout the day followed by clearing at night.
Confidence in the forecast decreases thereafter as there are hints of a pattern change across the islands despite some minor model discrepancies during beginning this weekend.
Latest model guidance suggests an upper-level low will make way into the proximity of the islands toward the latter end of the week, increasing the instability across the region.
The latest forecast has been derived from this GFS model run, exhibiting the upper-level low to arrive as soon as Saturday afternoon, enduring a wetter regime beginning Saturday and continuing into the first half of next week.
Additional moisture moving in from the tropics from the southeast and the remnants of a backdoor front from the north will increase overall clouds and showers, especially once the upper-level low propagates southward across the state.
These showers may become locally heavy at times and may even bring some snow during this period over the summits of Mauna Kea and Mauna Loa.
However, given that the development of these features and their arrival to the islands are still several days out, confidence remains low with regards to location and impacts at this time.
