Guidance shows a persistent trade pattern over the next seven 
days with precipitable water values tending to be near or somewhat
below climatology. Also expect upper ridging to prevail over and 
north of the main islands into midweek, possibly weakening by next
Thursday. Thus generally windward/mountain-focused showers should
be fairly light. The modest decrease in heights aloft may lead to
a subtle increase in rainfall around the end of the period. 
Initially moderate wind speeds should become brisk Friday onward 
due to one high passing by to the north on Friday and then another
high to the northwest/north by Tuesday-Wednesday. The latter high
should weaken some mid-late week but a decent gradient will 
likely remain over the state.


This is the final discussion of my career. It has been an honor 
and a source of great satisfaction to work in NOAA/NWS for the 
past 30+ years while witnessing the tremendous advances in weather
forecasting over that time. Now it's on to a retirement that 
hopefully offers as much excitement as the weather. Best wishes to
all, and to all happy forecasting!
