VALID 00Z SUN 27 APR 2025 - 00Z SUN 04 MAY 2025
EXPECT WINDS TO BECOME FAIRLY LIGHT DURING THE WEEKEND INTO EARLY
NEXT WEEK AS A SURFACE TROUGH MOVES INTO THE STATE FROM THE WEST.
MEANWHILE A SHARPENING UPPER TROUGH TO THE NORTH SHOULD
ULTIMATELY CLOSE OFF A LOW CENTER THAT TRACKS OVER OR JUST
NORTHEAST OF THE MAIN ISLANDS AROUND TUESDAY-TUESDAY NIGHT. THIS
IMPROVED GUIDANCE CLUSTER FOR THE UPPER LOW REPRESENTS THE
SOUTHWESTERN HALF OF THE ENVELOPE FROM 24 HOURS AGO. THE
COMBINATION OF THESE FEATURES ALONG WITH AN AXIS OF ENHANCED
MOISTURE WILL LEAD TO THE POTENTIAL FOR SOME LOCALLY HEAVY SHOWERS
AND POSSIBLY A LITTLE THUNDER EARLY IN THE WEEK, WITH SEA/LAND
BREEZE FOCUS. GUIDANCE IS AGREEABLE AND CONSISTENT IN SHOWING A
RETURN OF MODERATE TO BRISK TRADES WITH WINDWARD/MOUNTAIN SHOWER
FOCUS FROM MIDWEEK ONWARD, AS THE UPPER LOW CONTINUES EASTWARD AND
SURFACE HIGH PRESSURE PASSES BY TO THE NORTH. IN ADDITION
RAINFALL SHOULD TREND LIGHTER AS PRECIPITABLE WATER VALUES DECLINE
TO NEAR OR SLIGHTLY BELOW CLIMATOLOGY.
