HONOLULU (HawaiiNewsNow) - "Baby, it's cold outside!" The very cool temperatures we experienced overnight will continue today and tonight. Highs across the state will mostly be in the low to mid 70s. Overnight lows will reach down toward 60 again. The northerly flow of cool, dry air will last until mid-day Saturday when the winds will turn westerly.

 We are experiencing a rather unusual weather dynamic, with a strong, cold, upper low and cool, rather dry surface conditions. The last time we saw this scenario was on January 31, 1985. There were scattered low-topped thunderstorms that day, so the slight chance of thunderstorms is in our forecast today. Drier, more stable conditions are expected Saturday. Sunday should see significant sunshine, although winds will turn southwesterly as a fairly robust cold front approaches from the northwest. That front should bring widespread cloudiness and moderate  to heavy showers to the islands Sunday night and Monday.

 The north shores of all islands and the west shore of Hawaii island are under a HIGH SURF ADVISORY. Two new swells are expected, one from the North and another from the Northwest. Also, a HIGH WIND WATCH will take effect at noon today (Friday) for the summit areas of Mauna Loa and Mauna Kea on the Big Island. Strong west winds of 45 miles per hour with gusts of 60 miles per hour are expected. There is a good chance the Watch will be upgraded to a Warning by late afternoon. The strong winds could combine with the cold air aloft to take wind chill readings down below 0 degrees Fahrenheit on the summits tonight. So a WIND CHILL ADVISORY is also possible for the Big Island summits.
