PERSISTENT EAST-NORTHEASTERLY TRADE WINDS WILL CONTINUE ACROSS
THE STATE THROUGH THE SHORT TERM. SOME UPTICK IN LOW-LEVEL
MOISTURE WILL RESULT IN HIGHER SHOWER COVERAGE TODAY INTO
WEDNESDAY.
BY LATER THIS WEEK INTO THE WEEKEND THE PRESSURE GRADIENT WILL
WEAKEN AS THE SUBTROPICAL HIGH TO THE NORTH MOVES AWAY AND A COLD
FRONT APPROACHES THE REGION FROM THE NORTHWEST. THE PRIMARY IMPACT
OF THIS CHANGE WILL BE A DECREASE IN TRADE WIND SPEEDS ALONGSIDE
A GENERAL REDUCTION IN TRADE SHOWER ACTIVITY. GIVEN THE WEAK
SYNOPTIC FLOW, SEA BREEZE SHOWERS OVER THE INTERIOR WILL BE
POSSIBLE.
HEADING INTO NEXT WEEK, MODELS SUGGEST A RETURN OF STRONGER
EASTERLY TRADE WINDS AND STANDARD TRADE SHOWERS. STILL NOT
ANTICIPATING HAZARDOUS WEATHER THROUGH EARLY NEXT WEEK.
