Today

ARTICLE CONTINUES BELOW AD

We expect mostly cloudy skies today and showers are likely. The area of instability that caused thunder, lightning and heavy rain conditions over the last couple of days is still in our vicinity. Therefore, the possibility of heavy rain and a slight chance of thunderstorms exists. I will watch the situation and bring you the latest should any severe weather pop up. East winds are forecasted up to about 15 mph. High temperatures from 78° to 83°.

UV index at 8 (“very high” exposure level)

Tonight

Mostly cloudy skies are expected with showers likely for windward spots and scattered showers for the leeward side. Northeast winds are forecasted from 10 to 20 mph. Low temperatures from 68° to 73° are expected.

Next Full Moon: 8:06 a.m. on Mar. 5

 

Looking Ahead 

Instability in our area will create moist and unstable conditions over Big Island through today. Locally breezy trade winds are expected to focus clouds and showers over windward slopes. Showery trade wind weather will continue through at least mid week, especially for the Big Island. Another area of instability is expected to bring unsettled weather next weekend or perhaps a couple days later. Will watch the models to see how the situation develops.
