VALID 00Z MON MAR 3 2025 - 00Z MON MAR 10 2025  
  
A COL DEVELOPS WITHIN THE SUBTROPICAL RIDGE AXIS AS A FRONTAL  
BOUNDARY CROSSES THE NORTHWESTERN ISLANDS EARLY IN THE WEEK, WITH  
THE SURFACE HIGH BUILDING NORTH OF THE STATE 30-35 DEGREES NORTH.   
THE CORE OF THIS HIGH MAKES STEADY EASTWARD PROGRESS THROUGH THE  
WEEK, WITH ANOTHER COL IN THE RIDGE DEVELOPING NORTH OF THE STATE  
FOR THE END OF THE WEEK AS ANOTHER FRONTAL BOUNDARY APPROACHES.   
THERE IS GOOD OVERALL AGREEMENT IN THE ENSEMBLE MEANS REGARDING  
THE SYNOPTIC SCALE PATTERN THROUGH THE FORECAST PERIOD.  
  
THE MODEL GUIDANCE SUGGESTS THE HEAVIEST RAINFALL WITH THE COLD  
FRONT MONDAY SHOULD STAY WELL NORTH OF THE ISLANDS, WITH MAINLY  
TRADE WIND ENHANCED SHOWERS EXPECTED MOST DAYS AND NO MAJOR  
RAINFALL EVENTS ON THE HORIZON.  IN TERMS OF WINDS, BREEZY  
EASTERLY FLOW IS EXPECTED THROUGH MUCH OF THE WEEK WITH THE HIGH  
BUILDING IN TO THE NORTH.  THERE MAY BE SOME VEERING TO THE  
SOUTHEAST DEPENDING ON THE TIMING AND EVOLUTION OF THE NEXT  
TROUGH/COL.
