Friday 6th February 2026
Today light south winds and mostly dry.
Tonight light south winds with widely scattered showers, mostly from Hilo south.
Saturday light to moderate winds turn to northeast in the morning, widely scattered showers increasing to scattered Saturday night.
Sunday breezy northeast trade winds with rain, possibly heavy at times. Isolated thunder is also possible.
Sunday night/Monday morning thunder trades with heavy rain, strong winds from the east, the risk of flooding, and occasional thunder.
Monday and Monday night winds continue to be strong, rain trends towards less frequent.
Tuesday and Wednesday scattered showers with moderate to breezy eastly trade winds.
Thursday and beyond look like wet trades.
This weekend into early next week an upper level low to our west (500mb chart) brings colder air aloft and moves deep moisture over us from the south (700-300mb chart).
At the surface strong high pressure to our north and lower pressure to our south create a steep pressure gradient over us for strong and gusty trade winds (surface chart).
The combination of onshore wind, deep moisture (PW near 2"), and colder air aloft add up to heavy rains. It is likely to be the most stormy Sunday night/Monday morning.
A ridge builds in overhead Tuesday and Wednesday reducing the trade winds and showers. After that, models show a pattern of wet trades.
