A favored composite of overall compatible guidance indicates a
return of a more typical and drier trade flow pattern over the 
rest of the week as moisture levels gradually decrease as nearby 
troughing loses influence and as surface high pressure bridges to 
the north and northeast of the state. There is then a growing 
guidance signal in support of energetic mid-latitude upper trough 
passage to the north of the state later weekend and early next 
week that would disrupt trades while forcing an associated and
rainfall focusing cold front toward the islands to monitor.
