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

It’s partly cloudy here in Maui County this morning….with some cloudy areas.  The low temperature at my place was 54.5 degrees.

It remains partly cloudy at noon, lots a preponderance of high Cirrus clouds for the most part.

June Precipitation Summary for Hawaii:

June began with high pressure far to the northeast and a deep surface trough to the west of Kauai drew in higher moisture with east-southeast winds. This led to active windward showers around Kauai and Oahu and some sea breeze-driven showers on leeward O?ahu between Honolulu and N?n?kuli, with totals reaching up to 0.25 inches. The wettest windward spots, especially in the terrain of Kauai and Oahu, recorded between 0.5 to 1.5 inches of rainfall. The next couple of days were dominated by moderate to breezy trade winds and mostly dry conditions, with isolated to scattered windward and mountain showers.

Early morning showers returned June 4–5 along the Kona slopes of Hawaii Island (2-day totals around 0.5–1 inches). A decaying front and upper disturbance enhanced rainfall across windward areas on the 6th, enhancing windward and mountain showers, with rainfall up to 1.5 inches in some areas, and around 2 inches at Mt. Waialeale. Weaker trades and sea breezes on the 7th and 8th led to afternoon showers along Kona slopes (0.10 to 1.25 inches, and up to 2 inches near Kealakekua on the 8th), with light rainfall in interior Kauai and Maui. Elsewhere, upper-level troughing and stable mid-levels brought little more than high clouds and minimal additional. Light to moderate trades persisted on the 9th and 10th, with a surface trough west of Kauai and weakening inversion delivering increased moisture and windward showers, mainly over Kauai and Oahu.

Trades strengthened to locally breezy June 11th through the 17th as high pressure built north of the state. Most areas remained dry during this stretch, though a few shallow moisture bands brought scattered windward and mountain showers. Gauges recorded up to 0.25 inches on the night of the 12th to 13th (highest totals on Hawaii Island and Maui), with widespread showers (0.25 to 0.75 inches, locally near 1 inch) across the islands on the night of the 16th into the 17th. Beginning on the 18th, trades weakened slightly as the high shifted eastward. Moderate showers fell on the Kona slopes (0.25–1 inches) through the 20th. Trades returned to breezy-to-locally-strong by the 21st with minimal rainfall statewide.

A weak upper trough passed north of the islands June 23–25, enhancing windward/mountain showers. Kauai saw the heaviest rain (up to 2.9 inches at Mt. Waialeale), with 0.25–1 inches on Oahu and Maui, and 0.25–1.5 inches on Hawaii Island. June closed with breezy trades and generally drier conditions. However, on the 30th, southeast winds allowed localized leeward/interior showers, including 0.1–0.5 inches over interior valley sites of Oahu (around Pearl Harbor), ~0.15 inches for leeward Kauai, and up to 1 inches on the Kona slopes.

 

Hawaii’s Broad Brush Weather Overview:  A strong high pressure ridge north of the Hawaiian Islands will keep breezy to windy trade winds in the forecast through Tuesday. The strongest winds remain in the forecast for the windier areas of Maui and Hawaii Counties.

Dry weather conditions will combine with these strong gusty winds to produce elevated fire danger across the state. Wind speeds will decrease Wednesday onward. A stable ridge aloft will keep only brief passing showers in the forecast favoring windward and mountain areas. Leeward areas will remain dry through the week.

Hawaii’s Weather Details: The two primary weather themes this week will revolve around the breezy to windy trade winds, and the dry afternoon humidity levels lasting through Tuesday. Satellite imagery shows stable stratocumulus clouds riding in on the trade winds. The low tops of these clouds will only produce brief passing showers, as they are driven up the windward mountain slopes of each island in this stable environment.

Temperature inversion heights will range from 6,000 to 7,000 feet today, dropping into the 5,000 to 6,000 foot range Tuesday. Wind speeds observations on Sunday afternoon verified with our low end Wind Advisory forecast. Several areas observed sustained winds around 30 mph with gusts from 40 to 50 mph over the windier areas of Molokai, Maui and the Big Island. Wind speed trends are expected to increase slightly later today. Wind observations on Kauai and Oahu showed lower speeds, below advisory thresholds with sustained winds in the 15 to 25 mph range along with higher gusts up to 35 mph.

The Wind Advisory for windier areas of Maui and Hawaii Counties was expanded in coverage to include the summits of Mauna Kea and Mauna Loa, and also extended in time for 24 hours, now lasting through Tuesday afternoon. Wind speeds will likely peak later today and tonight, before a slight decreasing trend for most areas on Tuesday.

Trade wind speeds will continue to trend lower each day through the week, reaching more moderate wind speed ranges by this weekend. The combination of stronger winds along with stable and dry minimum afternoon humidity levels will elevate fire weather concerns each afternoon through Tuesday.

Fire weather: Breezy to windy trade winds with stable and dry conditions will persist through Tuesday. Minimum relative humidity at lower leeward elevations will likely fall to around 45 percent each afternoon, and with the inversion dropping to as low as 5,000 feet winds will become gusty over and downwind of island mountains. This will result in near critical fire weather conditions over dry leeward areas at times.

Hawaii’s Marine Environment:  High pressure will remain far north of the islands for the next several days, which will support fresh to strong trades across the area. The Small Craft Advisory has been extended until 6pm Tuesday, but this will likely need to be extended for at least some waters as the gusty trades persist. The surface high will move eastward and weaken slightly during the second half of the week, but winds are likely to remain locally breezy in the typical windier channels and waters.

South shore surf is expected to slowly decline as a south swell fades. The next small, long-period south swell is expected to arrive late Tuesday, peaking on Wednesday. This swell may boost south-facing shore surf heights to near summertime averages for the middle of the week. It will then decline through Friday.

Surf along east-facing shores will be rough and choppy in response to the gusty easterly trade winds throughout the next few days.

Interesting:  Ocean, Atmosphere Equally Responsible for Atlantic ‘Cold Blob,’ Scientists Find

A patch of the Atlantic Ocean just south of Greenland is cooling while much of the world warms. The origin of this “cold blob” has been linked to weakening ocean currents that help regulate global climate — called the Atlantic Meridional Overturning Circulation (AMOC). A team of scientists led by Penn State has found a weakening AMOC impacts not just the ocean but also the atmosphere, and that these two factors may contribute equally to the cold anomaly.

The researchers reported their findings in the journal Sciences Advances.

“In the past century, most of the planet has warmed while the subpolar North Atlantic has been stubbornly cooling,” said Pengfei Zhang, an assistant research professor in the Department of Meteorology and Atmospheric Science at Penn State and a co-author on the study. “Our findings help explain why this so-called cold blob exists and shed light on how future changes in ocean currents could ripple through the climate system.”

Previous studies on the cold blob have focused on ocean currents that bring warm water to the North Atlantic. But a cooling ocean will also result in a cooler, drier atmosphere, which can further amplify the cold anomaly, the scientists said.
