Residents in Honolulu can expect light and variable winds today moving into tomorrow as a dry and stable air mass dominates the region, limiting rainfall opportunities, according to the National Weather Service Honolulu. Islanders should take pleasure in pleasant afternoons as the weather forecast anticipates dew points to stay in the lower to mid 60s, which will allow for cooler evening temperatures below normal through the weekend.
A weak shallow front is predicted to stir modest changes by moving across the western end of the island chain on tomorrow night into Monday, while satellite imagery has been showing a high cloud flow is also crossing the state but expected to thin out today, which will keep skies relatively clear, especially as high clouds associated with the jet streak aloft will begin to dissipate across the western half today then the eastern end by Monday, as the National Weather Service Honolulu indicates.
The upcoming weather conditions are not anticipated to cause significant disruptions, with minimal impacts and only a slight uptick in shower activity predicted preceding the frontal passage, as for aviation, light winds will maintain sea and land breezes until mid-week when light to moderate trades are expected to return, and in the meanwhile, VFR conditions should persist, although some light SHRA and isolated brief MVFR conditions are possible in the evenings particularly along windward and mauka locations.
For those taking to the sea, weak high pressure will maintain gentle sea conditions through most of the weekend, though a weak front into the far western waters by tomorrow evening is anticipated before dissipating by Tuesday afternoon and as for surfers, the excitement builds as north and west facing beaches can expect increasing swell, approaching High Surf Advisory criteria tomorrow before subsiding early next week, also an elevated surf on east-facing shores will be noticed as more northerly swells peak today into tomorrow, wrapping into eastern exposures.
From a fire weather standpoint, despite the elevated KBDI values across the state and the potential for relative humidity values to dip below the critical 45% threshold during afternoon hours, the good news is that lighter winds are expected to mitigate fire weather concerns for the time being, as per the forecast, so for now, no watches, warnings, or advisories have been issued.
