IMPROVING CONDITIONS WILL CONTINUE TO BE THE CASE GOING THROUGH
SUNDAY AFTER THE RECENT INCLEMENT WEATHER FROM THE KONA LOW, WITH
A COL REMAINING IN THE SUBTROPICAL RIDGE AXIS IN ITS WAKE NORTH OF
THE STATE THROUGH MONDAY. THE ENSEMBLE MEANS INDICATE THE
SUBTROPICAL HIGH WILL BUILD IN BETWEEN 30-35 DEGREES NORTH BY
MID-WEEK, AND THIS HIGH WILL MOVE EAST AS A STORM SYSTEM NEAR 40
DEGREES NORTH APPROACHES WITH A TRAILING COLD FRONT REACHING THE
FAR NORTHWESTERN ISLANDS BY LATE WEEK, WITH THE GEFS MEAN FASTER
WITH THIS SYSTEM COMPARED TO THE EC MEAN.
TRADE WINDS WILL GENERALLY BE MORE VARIABLE GOING THROUGH THE
WEEKEND WITH THE COL NORTH OF THE STATE, BUT WINDS SHOULD BECOME
NOTICEABLY STRONGER OUT OF THE EAST TO NORTHEAST BY TUESDAY AND
WEDNESDAY WITH THE SURFACE HIGH PASSING NORTH OF THE STATE. SOME
VEERING OF THE FLOW TO THE SOUTHEAST IS LIKELY GOING INTO THE END
OF THE WEEK WITH THE FRONTAL BOUNDARY APPROACHING FROM THE
NORTHWEST. RAINFALL IN THE WAKE OF THE KONA LOW SHOULD RETURN TO
THE FAVORED UPSLOPE AREAS WITH THE DEEPEST MOISTURE REMAINING WELL
TO THE SOUTH.
