Well wish me luck. Officially under a hurricane warning now as of 5pm. Expecting a high end cat 1 impact here, maybe higher. Yeah we’ll be fine eventually, but it’s going to be a rough 72-96 hours. Most stores sold out of water yesterday, but luckily we were able to locate some more in Waikiki today. Not sure how well Aulani is built to handle such an impact but I guess we’re going to find out.

Be safe x85

With my .07" of rain today it boosted my monthly total to 11.38" which is the second wettest August in my 45 years of record keeping and overall the sixth wettest month.

Wettest months:

2 - 15.79"  October 2005

3 - 14.21"  September 1999 (aided by Hurricane Floyd)

4- 11.97"   May 1989

5 -11,88"   April 2007

6 - 11.38:  August 2018 (as if August 23)

 

Total precipitation for 2018 so far   46.90"     Total precipitation since July 15, 2018  - 17.55"

Looks like hurricane warnings for Maui and Hawaii are overdone. Maybe volcano summits see hurricane force wind gusts but most likely TS winds for those islands.  Looking at euro and ensembles appears same may be true for Oahu. Regardless, it looks like the worse case scenario is less likely, so you should get some decent video of gusty showers.  Hope the rest of your stay is back on track once Lane moves on.  

Regardless, I’m taking this seriously. I still think we get gusts to hurricane strength where I am and sustained winds over 60mph tomorrow. It’s not going to be a major when it gets here, but then again I never expected it would be. 

Still 135 mph max at 8am

Remainder of August averaging 80degs., or 7degs. AN.

Month to date is  +2.1[77.7] and should end near +2.9[78.1].   This just makes the Top Ten.

Should get mighty interesting with a big ridge in the east and the tropics finally waking up, both the gfs and Euro have started to show more tropical systems in the LR.

But the CFS which can be full of exaggerated systems near the EC, looks like a ***** cat during the next 30 days.   High pressure predominates in eastern half of US.   Best chance mid-month, weak system.   Precip. should be near Normal for the month.

Following the big heat next week, Euro and GFS have a cooler back door pattern with easterly flow for the Labor Day weekend. It has been a challenge all summer and spring to getting decent beach weather on the weekends. The top beach days this summer have often been during the week. This doesn't help people that have to work during the week.

Enjoy it. That is a great beach to miss the weekend crowds. Today was our one big radiational cooling morning for the whole month.

Models are trending towards cutting off the heat wave early, looks like the 90s will be confined to Mon-Wed.

Heat reloads after next weekend, EPS shows even more ridging for early September. 

Getting 90s in September is a lot more difficult, but the potential is definitely there.

You know it's going to get hot this week when both the Euro and GFS MOS have mid to upper 90's. The heat index will go over 100 with the dew points in the 70's. Closer to normal temperatures expected for next Thursday through Saturday behind the backdoor cold front.

Looks like models are less with the closed low / easterly flow next weekend and more of a 2 -3 (Fri-sat/ sun) day cool down towards normal with more heat on/around labor day itself and into sep 4th week.  850s peaking 18 - 22 Tue - thu (8 28 - 30) ahead of front

As of today station Aug mean temp stands at 76.9°...Warmest on 40 year record is 78.6° set in 2016, so with the up coming warmth will probably finish  3rd or so warmest.

Interesting pattern since meteorological winter of the last month of each season having the warmest departure.

LGA

Dec...-2.0

Jan...-1.5

Feb...+7.1

Mar....-1.4

Apr.....-3.3

May..+4.9

Jun...+0.7

February was +6.7F at KHPN and so far August has been +4.7F. Last month was +2.2. April was a coldest departure from normal at -2.1F, since March of 2015, which was -2.7 and February 2015 which was -6.7F. That February was the coldest departure from normal I have in that dataset since December 2010. Overall since I began compiling this data for tick projects, KHPN is running +1.8F above the 1981-2010 normals.

I agree, my thinking has been that  we are close to 2 degrees above the 1981-2010 average for today's climate.

August will likely finish +3 to +4 and Feb was a blowtorch as noted above...

I meant after Feb. I do agree that we are really about 2 degrees in reality over the 1981-2010 average today. Perhaps we should use 1.5 to 2 degrees over those averages and that would fit for today's climate.
