Synopsis

We will begin to see the threat for heavy rain increase late tonight into Wednesday as the front moves through from west to east on Wednesday. The front will produce widespread rain and a few thunderstorms and gusty winds. Drier and cooler air will spread over the islands behind the front and continue into the weekend.

Discussion

Latest satellite imagery shows the leading edge of the cold front roughly 300 miles northwest of Kauai this afternoon. As this front approaches the state tonight, we should see the south to southwest winds and showers increasing over the western half of the state tonight. As the leading edge of the front reaches Kauai early Wednesday morning, the chances of thunderstorms will be on the increase. As the front nears Oahu Wednesday morning, added support from the upper levels of the atmosphere is expected to further enhance precipitation along the front. This will likely cause water ponding issues during the morning commute on Wednesday over Oahu. Besides the rainfall, breezy southwest winds ahead of the front could produce some strong gusts especially over the northeast side of the islands. The leading edge of the front is then expected to move into Maui County late morning into the afternoon. As the front moves through Maui, it is expected to gradually weaken as it approaches Big Island Wednesday afternoon. Thunderstorms are still expected along and ahead of the front and the main issues will likely be related to any thunderstorm development. Temperatures will be cold enough for snow over the summits of Mauna Kea and Mauna Loa on the Big Island and we could see several inches of snow Wednesday afternoon into Wednesday night. High pressure will then build behind the front and will bring cool and dry northerly winds. Temperatures are expected to drop down into the low 60s for many areas Wednesday night and Thursday night and into the 50s for select locations behind the front.

Funny Weather News:


Annual Groundhogs Day tradition with Punxsutawney Phil was pulled from his burrow in Gobbler's Knob Tuesday morning at 7:25 am EST (Eastern Standard Time) and saw his shadow, which, according to legend, means six more weeks of winter.
