A cold front will approach and stall west of Hawaii in 
association with a deep trough and cutoff low west of the state. 
Heavy rainfall along the front is likely to remain west of the 
main islands. Wind speeds across the entire island chain, but 
especially the western islands, look moderate to gusty later in 
the week, but should moderate back to normal easterly trades by 
the weekend. A compact cut off low will meander east of the state 
this weekend as well, which may lead to some increased 
precipitation for eastern parts of the Big Island. Another cold 
front may approach Hawaii around mid week next week, but there is 
uncertainty on how close it will be.
