Hawaii’s Mountains – Here’s a link to the live webcam on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii. These webcams are available during the daylight hours here in the islands, and at night whenever there’s a big moon shining down. Also, at night you will be able to see the stars, and the sunrise and sunset too…depending upon weather conditions.

~~~ Hawaii Weather Narrative ~~~

 

Glenn’s Sunday comments: I’m home here in upper Kula, Maui, Hawaii

Good day everyone, I hope you have a great Sunday wherever you happen to be spending it.

521am, it’s clear with a just a few clouds this morning here in Kula, with a low temperature of 52.5 degrees at my place.

Happy Mother’s Day to all you Mom’s out there, we love you!

Hawaii’s Broad Brush Weather Overview:  Weather conditions are improving across the state, as the upper level low slowly drifts eastward away from the island chain. Localized heavy rain and isolated thunderstorms will be limited to the eastern half of the state.

Brief periods of showers in a light wind pattern will continue into the first half of the new week. A stronger low approaches the islands from the north Wednesday, with unstable southerly kona winds, pulling up deeper tropical moisture, and producing periods of heavy showers and thunderstorms across the state through at least Friday. The weather for next weekend may remain unsettled.

Hawaii’s Weather Details:  The upper level low over the islands continues to weaken and slowly drift east. The best forcing and lift associated with an upper level trough on the south side of this low, has moved east of the Big Island, decreasing heavy shower and thunderstorm activity across the state.

Light southeasterly winds will continue to interact with local scale land and sea breezes over each island through Tuesday. The best chances for clouds and showers will develop over island mountain and interior sections each day, with decreasing clouds and showers at night.

Monday through Tuesday…heavy rain and thunderstorm threats diminish Monday, as the low weakens and slowly drifts northeastward away from the state. Light southeasterly winds will continue to allow local scale land and sea breezes to develop over all islands. Weak upper level troughing however will keep brief periods of showers in the forecast, favoring island mountain and interior sections each afternoon and early evening through Tuesday.

Wednesday through Friday…the latest model guidance suggests that another unseasonably strong low will approach the islands from the north Wednesday. A surface low forming under the upper low will be stronger than the previous system, and may produce southerly kona winds over the western half of the state.

The latest forecast guidance shows the surface low center will setup roughly 600 miles northwest of Kauai by Thursday. Unsurprisingly, this surface low position has changed a bit over the past 24 hours. However model solutions continue to show a trailing surface trough with southerly kona winds brewing over the islands through this time period.

This unstable southerly kona wind flow and surface trough may bring another round of heavy rain and thunderstorms favoring the western islands of Niihau, Kauai and Oahu from Wednesday through Friday. In the latest model solutions Kauai County and Oahu are under the highest threats for flooding, thunderstorms, and strong gusty winds during this time period.

This portion of the long range weather forecast will likely change over time. Much of these severe weather impacts are highly dependent upon the precise location of this low pressure system and surface trough relative to each island. Small changes to the location of the low center will make large changes to the forecast for each island. Stay tuned for changes to the long range local weather forecast, as the time period grows shorter, and island by island weather impacts evolve.

Interesting:  NOAA Expands Availability of New Heat Forecast Tool Ahead of Summer

NOAA is expanding the availability of a new experimental heat tool called HeatRisk ahead of the hot summer months. A collaboration with NOAA’s National Weather Service (NWS) and the Centers for Disease Control and Prevention (CDC), HeatRisk provides information and guidance for those who are particularly vulnerable to heat and may need to take extra precautions for their health when the temperature rises.

HeatRisk provides historical context for high temperature forecasts, identifying how unusual the heat will be for any given time of year across a spatial area with coverage across the contiguous U.S. It also identifies temperatures that are expected to bring increased heat impacts over a 24-hour period, up to seven days in advance.

The tool takes into account cumulative impacts of heat by identifying the expected duration of the heat, including both daytime and nighttime temperatures. HeatRisk is divided into a number and color-coded scale — ranging from zero to four and minor to extreme — that identifies the risk of heat-related impacts.
